Abstract: Sentiment analysis on social media such as Twitter is a challenging task given the data characteristics such as the length, spelling errors, abbreviations, and special characters. Social media sentiment analysis is also a fundamental issue with many applications. With particular regard of the tourism sector, where the characterization of fluxes is a vital issue, the sources of geotagged information have already proven to be promising for tourism-related geographic research. The paper introduces an approach to estimate the sentiment related to Cilento’s, a well known tourism venue in Southern Italy. A newly collected dataset of tweets related to tourism is at the base of our method. We aim at demonstrating and testing a deep learning social geodata framework to characterize spatial, temporal and demographic tourist flows across the vast of territory this rural touristic region and along its coasts. We have applied four specially trained Deep Neural Networks to identify and assess the sentiment, two word-level and two character-based, respectively. In contrast to many existing datasets, the actual sentiment carried by texts or hashtags is not automatically assessed in our approach. We manually annotated the whole set to get to a higher dataset quality in terms of accuracy, proving the effectiveness of our method. Moreover, the geographical coding labelling each information, allow for fitting the inferred sentiments with their geographical location, obtaining an even more nuanced content analysis of the semantic meaning.

Abstract: Mosaic is an ancient type of art used to create decorative images or patterns combining small components. A digital version of a mosaic can be useful for archaeologists, scholars and restorers who are interested in studying, comparing and preserving mosaics. Nowadays, archaeologists base their studies mainly on manual operation and visual observation that, although still fundamental, should be supported by an automatized procedure of information extraction. In this context, this research explains improvements which can change the manual and time-consuming procedure of mosaic tesserae drawing. More specifically, this paper analyses the advantages of using Mo.Se. (Mosaic Segmentation), an algorithm that exploits deep learning and image segmentation techniques; the methodology combines U-Net 3 Network with the Watershed algorithm. The final purpose is to define a workflow which establishes the steps to perform a robust segmentation and obtain a digital (vector) representation of a mosaic. The detailed approach is presented, and theoretical justifications are provided, building various connections with other models, thus making the workflow both theoretically valuable and practically scalable for medium or large datasets. The automatic segmentation process was tested with the high-resolution orthoimage of an ancient mosaic by following a close-range photogrammetry procedure. Our approach has been tested in the pavement of St. Stephen's Church in Umm ar-Rasas, a Jordan archaeological site, located 30 km southeast of the city of Madaba (Jordan). Experimental results show that this generalized framework yields good performances, obtaining higher accuracy compared with other state-of-the-art approaches. Mo.Se. has been validated using publicly available datasets as a benchmark, demonstrating that the combination of learning-based methods with procedural ones enhances segmentation performance in terms of overall accuracy, which is almost 10% higher. This study's ambitious aim is to provide archaeologists with a tool which accelerates their work of automatically extracting ancient geometric mosaics.

Abstract: Starting from a multi–scalar and multi–dimensional survey, most interdisciplinary researches, based on representation, are becoming a tool for dialogue between the new trends of Artificial Intelligence (AI) and the most compelling needs of our CH. The approach here proposed stems from the desire to understand how much of the skills useful in architecture analysing and modelling can be made available to the “machine”, with the goal to accelerate cognitive or management processes. Some HBIM models, as an existing digital heritage, were used to obtain the semantic intelligence. From this specialised intelligence comes a cyclical path which, through AI, transforms this knowledge into new forms of collective intelligence, at the service of the heritage. The paper presents a research that brings very promising results for the segmentation of point clouds and the facilitation of ScanToHBIM approaches, made possible by the large amount of data acquired on the Ducal Palace of Urbino.

Autore/i: Pierdicca, Roberto; Frontoni, Emanuele; Puggioni, Maria Paola; Malinverni, Eva Savina; Paolanti, Marina
Classificazione: 2 Contributo in Volume
Abstract: Augmented and virtual reality proved to be valuable solutions to convey contents in a more appealing and interac- tive way. Given the improvement of mobile and smart devices in terms of both usability and computational power, contents can be easily conveyed with a realism level never reached in the past. Despite the tremendous number of researches related with the presentation of new fascinating applications of ancient goods and artifacts augmenta- tion, few papers are focusing on the real effect these tools have on learning. Within the framework of SmartMarca project, this chapter focuses on assessing the potential of AR/VR applications specifically designed for cultural heritage. Tests have been conducted on classrooms of teenagers to whom different learning approaches served as an evaluation method about the effectiveness of using these technologies for the education process. The chapter argues on the necessity of developing new tools to enable users to become producers of contents of AR/VR experiences.

Classificazione: 1 Contributo su Rivista
Abstract: The aim of this manuscript is to define an operational pipeline of work, from data acquisition to the report creation, for the smart management of PV plants. To achieve such an ambitious result, we exploit the implementation of a conceptual model, deployed through a relational database to retrieve any kind of information related to the PV plant. The motivation that drove this research is due to the increasing construction of PV plants. In fact, following European and international investments that heavily stimulated the use of clean energy, the need to maintain PV plants in their maximum efficiency for their whole lifecycle emerged, to bring about benefits from both the ecological and the economic points of view. While the research community focuses on finding new and automatic ways to detect faults automatically, few efforts have been made considering the so-called Operation and Maintenance (O&M). A relational conceptual model may facilitate the management of heterogeneous sources of information, which are common in complex PV plants. The purpose of the present study is to provide companies and insiders with a GIS-based tool to maintain the energy efficiency of a PV plant. Indeed, it is a common practice used by companies dealing with O&M of PV plants to create technical reports about the health status of the plants. This operation, made manually, is very time consuming and error prone. To overcome this latter drawback, this work attempts to encourage the use of GIS in the PV plants O&M, which proves to be efficient to deal with fault management and to assure a good level of energy production. The developed conceptual model, tested on two real case studies, proved to be complete, cost-effective and efficient to be replicated in other existing plants.

Abstract: Industry 4.0 is reinventing the way in which production is performed. Based on its eight pillars, I4.0 environments are adopting digital solutions in order to make production smart. One of these is the concept of augmented operator, which can act with the aid of digital tools to facilitate daily work. Augmented Reality can represent the turnkey. In this light, the aim of this research is to present a case study of a “security and safety” application through the use of AR smart glasses, tested in a real scenario. For our experiments, Vuzix Blade smart glasses have been tested in combination with a cloud-based architecture connected with an oil-extractor plant. The goal is to develop an AR application that allows to assist the operator during the working process. In particular, it acts as a guide system for the operator who wears glasses, provides remote support (remote operator) and, from a security point of view, sends real-time alerts in dangerous situations. The application has been validated after a number of practical tests carried out by specialised technicians who normally perform the work.

Abstract: This paper describes REMEMBER, an EU project which aims at establishing a network for joint valorization of 8 ports in Italy and Croatia, trying to shift the paradigm of touristic flows toward a sustainable tourism. The key point is an innovative ICT architecture, modular and scalable, to share information at different system levels of detail and fruition, with an interoperable and multi-channel approach. Given its flexibility, contents can be conveniently displayed in different ways: Web portals, fixed installations, mobile devices etc. This infrastructure enables a great number of Digital Experiences (DEs) that can be exploited at both global and local scale. Since the project is on going, the paper presents a first overview of the instantiate methodology, as well as briefly introduces the DEs that are currently designed and, finnaly, reports a prospective outlook related to the post-pandemic scenario.

Classificazione: 1 Contributo su Rivista
Abstract: Point clouds obtained via Terrestrial Laser Scanning (TLS) surveys of historical buildings are generally transformed into semantically structured 3D models with manual and time-consuming workflows. The importance of automatizing this process is widely recognized within the research community. Recently, deep neural architectures have been applied for semantic segmentation of point clouds, but few studies have evaluated them in the Cultural Heritage domain, where complex shapes and mouldings make this task challenging. In this paper, we describe our experiments with the DGCNN architecture to semantically segment historical buildings point clouds, acquired with TLS. We propose a variation of the original approach where a radius distance based technique is used instead of K-Nearest Neighbors (KNN) to represent the neighborhood of points. We show that our approach provides better results by evaluating it on two real TLS point clouds, representing two Italian historical buildings: the Ducal Palace in Urbino and the Palazzo Ferretti in Ancona.

Abstract: In the Digital Cultural Heritage (DCH) domain, the semantic segmentation of 3D Point Clouds with Deep Learning (DL) techniques can help to recognize historical architectural elements, at an adequate level of detail, and thus speed up the process of modeling of historical buildings for developing BIM models from survey data, referred to as HBIM (Historical Building Information Modeling). In this paper, we propose a DL framework for Point Cloud segmentation, which employs an improved DGCNN (Dynamic Graph Convolutional Neural Network) by adding meaningful features such as normal and colour. The approach has been applied to a newly collected DCH Dataset which is publicy available: ArCH (Architectural Cultural Heritage) Dataset. This dataset comprises 11 labeled points clouds, derived from the union of several single scans or from the integration of the latter with photogrammetric surveys. The involved scenes are both indoor and outdoor, with churches, chapels, cloisters, porticoes and loggias covered by a variety of vaults and beared by many different types of columns. They belong to different historical periods and different styles, in order to make the dataset the least possible uniform and homogeneous (in the repetition of the architectural elements) and the results as general as possible. The experiments yield high accuracy, demonstrating the effectiveness and suitability of the proposed approach.

Classificazione: 1 Contributo su Rivista
Abstract: Nel panorama della ricerca sul patrimonio storico, la segmentazione semantica delle nuvole di punti 3D sta guadagnando sempre più attenzione, poiché permette di riconoscere automaticamente gli elementi architettonici storici. Tuttavia, la segmentazione semantica è particolarmente difficile nell'architettura storica e classica, a causa della complessità delle forme e della limitata ripetibilità di elementi in edifici diversi, che rende difficile definire modelli comuni all'interno della stessa classe architettonica. Inoltre, poiché i modelli di deep learning richiedono una quantità considerevolmente grande di dati annotati per essere addestrati al fine di gestire adeguatamente nuove scene, la mancanza di sufficientemente ampi data set di nuvole di punti annotate pubblicamente disponibili per edifici storici è un problema enorme, tanto da costituire un collo di bottiglia nella ricerca. D’altra parte, la creazione di una massa critica di nuvole di punti etichettate mediante annotazione manuale è molto dispendiosa in termini di tempo e poco pratica. A tal fine, in questo lavoro viene esplorata l'idea di sfruttare i dati sintetici delle nuvole di punti per addestrare modelli di deep learning che eseguono la segmentazione semantica delle nuvole di punti. Per raggiungere questo scopo, viene presentata una versione migliorata della Dynamic Graph CNN (DGCNN) denominata RadDGCNN. Negli esperimenti presentati in questo lavoro, i modelli vengono addestrati su dataset sintetici (disponibili pubblicamente) di due diversi edifici storici: Palazzo Ducale di Urbino e il Palazzo Ferretti ad Ancona. La filiera si imposta sui modelli degli stessi edifici acquisiti tramite Laser Scanner Terrestre. La rete RadDGCNN produce buoni risultati, dimostrando migliori prestazioni di segmentazione sui dataset reali

Classificazione: 1 Contributo su Rivista
Abstract: In the Cultural Heritage (CH) context, art galleries and museums employ technology devices to enhance and personalise the museum visit experience. However, the most challenging aspect is to determine what the visitor is interested in. In this work, a novel Visual Attentive Model (VAM) has been proposed that is learned from eye tracking data. In particular, eye-tracking data of adults and children observing five paintings with similar characteristics have been collected. The images are selected by CH experts and are-the three “Ideal Cities” (Urbino, Baltimore and Berlin), the Inlaid chest in the National Gallery of Marche and Wooden panel in the “Studiolo del Duca” with Marche view. These pictures have been recognized by experts as having analogous features thus providing coherent visual stimuli. Our proposed method combines a new coordinates representation from eye sequences by using Geometric Algebra with a deep learning model for automated recognition (to identify, differentiate, or authenticate individuals) of people by the attention focus of distinctive eye movement patterns. The experiments were conducted by comparing five Deep Convolutional Neural Networks (DCNNs), yield high accuracy (more than 80%), demonstrating the effectiveness and suitability of the proposed approach in identifying adults and children as museums’ visitors.

Classificazione: 1 Contributo su Rivista
Abstract: Historical heritage is demanding robust pipelines for obtaining Heritage Building Information Modeling models that are fully interoperable and rich in their informative content. The definition of efficient Scan-to-BIM workflows represent a very important step toward a more efficient management of the historical real estate, as creating structured three-dimensional (3D) models from point clouds is complex and time-consuming. In this scenario, semantic segmentation of 3D Point Clouds is gaining more and more attention, since it might help to automatically recognize historical architectural elements. The way paved by recent Deep Learning approaches proved to provide reliable and affordable degrees of automation in other contexts, as road scenes understanding. However, semantic segmentation is particularly challenging in historical and classical architecture, due to the shapes complexity and the limited repeatability of elements across different buildings, which makes it difficult to define common patterns within the same class of elements. Furthermore, as Deep Learning models requires a considerably large amount of annotated data to be trained and tuned to properly handle unseen scenes, the lack of (big) publicly available annotated point clouds in the historical building domain is a huge problem, which in fact blocks the research in this direction. However, creating a critical mass of annotated point clouds by manual annotation is very time-consuming and impractical. To tackle this issue, in this work we explore the idea of leveraging synthetic point cloud data to train Deep Learning models to perform semantic segmentation of point clouds obtained via Terrestrial Laser Scanning. The aim is to provide a first assessment of the use of synthetic data to drive Deep Learning--based semantic segmentation in the context of historical buildings. To achieve this purpose, we present an improved version of the Dynamic Graph CNN (DGCNN) named RadDGCNN. The main improvement consists on exploiting the radius distance. In our experiments, we evaluate the trained models on synthetic dataset (publicly available) about two different historical buildings: the Ducal Palace in Urbino, Italy, and Palazzo Ferretti in Ancona, Italy. RadDGCNN yields good results, demonstrating improved segmentation performances on the TLS real datasets.

Abstract: The adoption of dissemination strategies based on Information and Communication Technologies (ICTs) has generated a paradigm shift, empowering users to identify, customize and exploit tourism services. The paper outlines an innovative way to disseminate the archaeological landscape, based on the Flaminia NextOne Distretto Culturale Evoluto (DCE) research project. The contribution summarizes the main achievements of the project in the light of technical improvements in AR applications and mobile cloud management, and also describes the collaborative approach of a public-private partnership. Data analytics from the web platform are also provided, in order to understand the potential and the drawbacks of this methodology. The discussion of the method, the pilot cases and their scalability derive from the main objective of the project which is to promote cultural heritage throughout the territory and to study the socio-economic implications of digital mediation, as discussed in the 2016 L&A En Route seminar. L’adozione di strategie di comunicazione basate su tecnologie dell’informazione e della comunicazione (TIC) ha generato un cambio di paradigma, consentendo agli utenti di identificare, personalizzare e sfruttare i servizi turistici. L’articolo delinea un modo innovativo per veicolare il paesaggio archeologico, basato sul progetto di ricerca Flaminia NextOne Distretto Culturale Evoluto (DCE). Il contributo riassume i principali risultati del progetto alla luce dei miglioramenti tecnici ottenuti nelle applicazioni AR e nella gestione di un cloud dati, nonché nell’approccio collaborativo del partenariato pubblico-privato. Viene fornita anche un’analisi dei dati della piattaforma web, al fine di comprendere le potenzialità e gli svantaggi della metodologia. La discussione del metodo, i casi pilota e la loro scalabilità derivano dal valore intrinseco del progetto per promuovere il patrimonio culturale diffuso sul territorio e studiare le implicazioni socio-economiche della mediazione digitale, come discusso nel seminario L&A En route del 2016.

Abstract: National Strategy For Cultural Heritage 2017-2027 is a Kosovo Government document that aims the enhancement of the system for the protection and preservation of Kosovan cultural heritage. Among the listed goals, one can find the promotion of an integrated data management approach towards cooperation platforms that involve advanced technologies and information systems applied to cultural heritage. In a country with a low technological progress, as Kosovo is, an innovative information management system like HBIM is a huge challenge. This research contributes in opening the debate about the use of HBIM even for historical architecture, illustrating a methodology of information management promoting the conservation and the valorization of a Kosovan ottoman mosque. The workflow pipeline started with the close range photogrammetric survey, obtaining first spherical panoramas and then the wire-frame processed in a 3D modelling environment, suitable to implement the HBIM project. Basing on the accuracy of the data acquisition, the availability of information about the building and the related level of knowledge, we proposed a semantic representation of the complex structure integrating in an HBIM collecting in an "ad hoc" database the geometrical building components, enriched with attributes as images, materials, decay, interventions, etc., linked to each features. Our approach is an example of how efficient semantic classification can be repeated for the analysis and the documentation of other similar ottoman mosque, simplifying the management of construction by a sort of unique and searchable archive. The advantage of the interoperability concept allows the data sharing is now stressed by HBIM.

Abstract: I recenti progressi nella tecnologia dei Multibeam Echosounder (MBES) hanno introdotto una gamma più ampia di bande operative capaci di coprire diverse centinaia di kHz e di offrire una migliore risoluzione di gamma per la raccolta di dati batimetrici. Tale tecnologia ha inoltre migliorato la capacità di discriminare i fondali marini, ponendo le basi per la ricerca sul backscattering multispettrale. In questo lavoro, sono presentati i risultati delle prime prove di un’indagine MBES multispettrale di una scogliera artificiale. La scogliera è costituita da piramidi e gabbie in calcestruzzo. Il sensore adoperato per le indagini è il Multibeam Echosounder EM 2040C, montato sulla barca da ricerca “Tecnopesca II” appartenente all’ISMAR – CNR di Ancona. I dati sono stati raccolti nell’agosto 2018 e successivamente analizzati per evidenziare variazioni da confrontare con dati monitorati da qualche decennio con sonar monofrequenza. Grazie all’alta risoluzione del MBES, i cambiamenti del fondale marino sono stati oggetto di studio per monitorare le strutture impiantate: molte delle gabbie e delle piramidi sono cadute cambiando la configurazione dell’impianto e la mappatura iniziale. Nel presente articolo saranno utilizzati metodi quantitativi, applicati per la segmentazione e la classificazione su dati MBES, sui dati batimetrici così da fornire informazioni sulla morfologia e la tessitura dei fondali marini. L’analisi è stata eseguita sia in ambiente GIS che con RSOBIA (Remote Sensing Object Based Image Analysis). A causa dell’assenza di verità a mare (ground-truth) è stato inoltre eseguito un primo approccio di classificazione unsupervised di tipo ISODATA (Iterative Self-Organizing Data Analysis Techinique Algorithm).

Abstract: In increasingly hyper-connected societies, where individuals rely on short and fast online communications to consume information, museums face a significant survival challenge. Collaborations between scientists and museums suggest that the use of the technological framework known as Internet of Things (IoT) will be a key player in tackling this challenge. IoT can be used to gather and analyse visitor generated data, leading to data-driven insights that can fuel novel, adaptive and engaging museum experiences. We used an IoT implementation-a sensor network installed in the physical space of a museum-to look at how single visitors chose to enter and spend time in the different rooms of a curated exhibition. We collected a sparse, non-overlapping dataset of individual visits. Using various statistical analyses, we found that visitor attention span was very short. People visited five out of twenty rooms on average, and spent a median of two minutes in each room. However, the patterns of choice and time spent in rooms were not random. Indeed, they could be described in terms of a set of linearly separable visit patterns we obtained using principal component analysis. These results are encouraging for future interdisciplinary research that seeks to leverage IoT to get numerical proxies for people attention inside the museum, and use this information to fuel the next generation of possible museum interactions. Such interactions will based on rich, non-intrusive and diverse IoT driven conversation, dynamically tailored to visitors.

Abstract: Augmented Reality (AR) offers the possibility to enrich the real world with digital mediated content, increasing in this way the quality of many everyday experiences. While in some research areas such as cultural heritage, tourism, or medicine there is a strong technological investment, AR for game purposes struggles to become awidespread commercial application. In this article, a novel framework for AR kid games is proposed, already developed by the authors for other AR applications such as Cultural Heritage and Arts. In particular, the framework includes different layers such as the development of a series of AR kid puzzle games in an intermediate structure which can be used as a standard for different applications development, the development of a smart configuration tool, together with general guidelines and long-life usage tests and metrics. The proposed application is designed for augmenting the puzzle experience, but can be easily extended to other AR gaming applications. Once the user has assembled the real puzzle, AR functionality within the mobile application can be unlocked, bringing to life puzzle characters, creating a seamless game that merges AR interactions with the puzzle reality. The main goals and benefits of this framework can be seen in the development of a novel set of AR tests and metrics in the pre-release phase (in order to help the commercial launch and developers), and in the release phase by introducing the measures for long-life app optimization, usage tests and hint on final users together with a measure to design policy, providing a method for automatic testing of quality and popularity improvements. Moreover, smart configuration tools, as part of the general framework, enabling multi-app and eventually also multi-user development, have been proposed, facilitating the serialization of the applications. Results were obtained from a large-scale user test with about 4 million users on a set of eight gaming applications, providing the scientific community a workflow for implicit quantitative analysis in AR gaming. Different data analytics developed on the data collected by the framework prove that the proposed approach is affordable and reliable for long-life testing and optimization.

Abstract: Thrilling the society toward science and research is not trivial. Albeit the “academic industry” lavishes many efforts to spread its results not only among the insiders but to the whole mankind, the importance of sharing the knowledge of research is seldom a priority. The European Researcher Night is probably the most important EU action trying to overcome this limitation, putting altogether researcher from different disciplines to show their findings through stands, short communications and events. Within this framework, the event able to attracts citizens is the video mapping projection. In this article is described a multi-disciplinary process that makes use of a photogrammetric survey as an accurate source for video projection mapping. While well-established geomatics technologies (e.g. laser scanning and photogrammetry) paves the way for the virtual reconstruction of the architecture, they are even essential to perform analysis and studies which enables visual artist or art historians to tell the story of a building in a new and fascinating way. Besides the realization of the visual mapping and a critical discussion over the procedure that has been used to translate a 3D model in a visual storytelling of the building, the article also describes an innovative way that has been set up for the management of the whole SHARPER event. The system is app-based and was designed to allow the visitors to interact with the event directly from their smartphones; several active sensors have been displaced among the city, asking the user to search for virtual owls and to catch them by answering some questions, engaging the people by exploiting the gamification paradigm. This latter has been stressed further, since the video projection was conceived as a competition between the students of the Master degree course in Engineering-Architecture. Through the application, the attendant to the visual mapping where thus enabled to vote his/her favourite video in real-time.

Abstract: In recent years, the digitization of historical data related to the architectural heritage and the development of ICT-based methodologies applied to cultural goods have become increasingly relevant. In this context, the use of GIS (Geographical Information System) is growing significantly, with the aim of collecting, analysing and managing heterogeneous data in a spatial context. Given such premise, the site identified for this case-study is a historical Italian Garden into the Villa Buonaccorsi in Potenza Picena (MC, Italy). The project aims at creating a methodology, that organizing natural and artificial elements in the GIS, to support management and planning of this landscape architecture, considering also the changes during the time. A suitable GIS can promote and ensure a correct use of the heritage knowledge, preserving the historical identity, overlaying the data. The data management system, specifically developed for this case, is based on an open source GIS, where surveyed data coming from different sources and the relation to the attributes have been descripted in a conceptual model. The inventory of this geodatabase, in a dedicated GIS, has allowed to perform some queries, making in output a dialogue box with all the information, in form of report, useful to the manager of a historical garden. The structure of the GIS can significantly to help who works with similar cases and it can be useful for analysis, management, storage and integration of information related to Italian gardens.

Classificazione: 1 Contributo su Rivista
Abstract: Umm ar-Rasas is a Jordan archaeological site, located 30 km southeast of the city of Madaba, in the northern part of Wadi Mujib. It preserves findings dating back the period from the end of 3rd to the 9th century AD and, since 2004, it belongs to the world heritage list of UNESCO. In 2015 a multidisciplinary work was undertaken over the archaeological site, mainly focusing on the Church of Saint Stephen, with the main purpose of enhancing the knowledge and documenting the conservation state of the polychrome mosaic floor, which covers the entire surface of the hall and presbytery. A huge amount of data has been collected, coming from archaeological and historical investigations, geophysics and geodetic inspections and geomatics surveying, which produced also a true orthophoto of the mosaic floor. Data has been organized in a geo-database, facilitating the exchange of information between different actors. Moreover, the management of data within a dedicated Geographic Information System (GIS), has allowed in-depth analysis for understanding the evolution of the iconographic repertoire that, over the centuries, has undergone several disfigurements due to the iconoclastic age. The knowledge of the mosaic has also been vital for the implementation of multimedia applications and for the creation of virtual experiences, in which the information can be conveyed and visualized directly on the virtual reconstruction of the whole archaeological site. The innovation of the proposed work, is therefore in the management of a data flow that can be exploited by different actors through different platforms: experts, thanks to the use of GIS, and visitors with the use of multimedia applications (such as Augmented Reality (AR) or highresolution web visualization) for dissemination purposes, in order to preserve this priceless mankind heritage.

Abstract: Purpose: The purpose of this paper is to demonstrate the importance of exploiting a geographic information system (GIS)-based data management, designed and implemented for an important monumental site. In particular, data collected during the years have been used to create a storytelling experience to disseminate the tangible and intangible heritage of Chan Chan (Peru), the wider site in mud bricks of Latin America. Design/methodology/approach: The paper discusses the steps that have been performed to use the data stored in a GIS, arguing over the importance of sharing the knowledge through web-based tools, and in particular by the implementation of a storytelling. In this context, the data were structured in interoperable forms in order to preserve the universal value of the archaeological site. The exploitation in an all-in-one solution of the archival research, field surveys and planning represents a step forward for let known ancient testimonies to the whole mankind. Findings: The GIS-based inventories represent the backbone for an affordable management of heritage resources. The novelty of the proposed approach lies on the creation of an integrated, accessible and updatable data system sharable on web. Originality/value: The GIS of Chan Chan is an example of documentation of a wide archaeological area (14 km2) with complex and heterogeneous data. The developed web tool makes use of these data which can be queried even by non-expert users. The pipeline of this paper can act as useful guidelines to practitioners and researchers who want to disseminate cultural information.

Abstract: National Strategy For Cultural Heritage 2017-2027 is a Kosovo Government document that aims the enhancement of the system for the protection and preservation of Kosovan cultural heritage. Among the listed goals, one can find the promotion of an integrated data management approach towards cooperation platforms that involve advanced technologies and information systems applied to cultural heritage. In a country with a low technological progress, as Kosovo is, an innovative information management system like HBIM is a huge challenge. This research contributes in opening the debate about the use of HBIM even for historical architecture, illustrating a methodology of information management promoting the conservation and the valorization of a Kosovan ottoman mosque. The workflow pipeline started with the close range photogrammetric survey, obtaining first spherical panoramas and then the wire-frame processed in a 3D modelling environment, suitable to implement the HBIM project. Basing on the accuracy of the data acquisition, the availability of information about the building and the related level of knowledge, we proposed a semantic representation of the complex structure integrating in an HBIM collecting in an "ad hoc" database the geometrical building components, enriched with attributes as images, materials, decay, interventions, etc., linked to each features. Our approach is an example of how efficient semantic classification can be repeated for the analysis and the documentation of other similar ottoman mosque, simplifying the management of construction by a sort of unique and searchable archive. The advantage of the interoperability concept allows the data sharing is now stressed by HBIM.

Abstract: Planning urban parks is a burdensome task, requiring knowledge of countless variables that are impossible to consider all at the same time. One of these variables is the set of people who use the parks. Despite information and communication technologies being a valuable source of data, a standardized method which enables landscape planners to use such information to design urban parks is still broadly missing. The objective of this study is to design an approach that can identify how an urban green park is used by its visitors in order to provide planners and the managing authorities with a standardized method. The investigation was conducted by exploiting tracking data from an existing mobile application developed for Cardeto Park, an urban green area in the heart of the old town of Ancona, Italy. A trajectory clustering algorithm is used to infer the most common trajectories of visitors, exploiting global positioning system and sensor-based tracks. The data used are made publicly available in an open dataset, which is the first one based on real data in this field. On the basis of these user-generated data, the proposed datadriven approach can determine the mission of the park by processing visitors' trajectories whilst using a mobile application specifically designed for this purpose. The reliability of the clustering method has also been confirmed by an additional statistical analysis. This investigation reveals other important user behavioral patterns or trends.

Abstract: Information and Communication Technologies (ICTs) and mobile devices are deeply influencing all facets of life, directly affecting the way people experience space and time. ICTs are also tools for supporting urban development, and they have also been adopted as equipment for furnishing public spaces. Hence, ICTs have created a new paradigm of hybrid space that can be defined as Senseable Spaces. Even if there are relevant cases where the adoption of ICT has made the use of public open spaces more “smart”, the interrelation and the recognition of added value need to be further developed. This is one of the motivations for the research presented in this paper. The main goal of the work reported here is the deployment of a system composed of three different connected elements (a real-world infrastructure, a data gathering system, and a data processing and analysis platform) for analysis of human behavior in the open space of Cardeto Park, in Ancona, Italy. For this purpose, and because of the complexity of this task, several actions have been carried out: the deployment of a complete real-world infrastructure in Cardeto Park, the implementation of an ad-hoc smartphone application for the gathering of participants’ data, and the development of a data pre-processing and analysis system for dealing with all the gathered data. A detailed description of these three aspects and the way in which they are connected to create a unique system is the main focus of this paper.

Abstract: A multimedia approach to the diffusion, communication, and exploitation of Cultural Heritage (CH) is a well-established trend worldwide. Several studies demonstrate that the use of new and combined media enhances how culture is experienced. The benefit is in terms of both number of people who can have access to knowledge and the quality of the diffusion of the knowledge itself. In this regard, CH uses augmented-, virtual-, and mixed-reality technologies for different purposes, including education, exhibition enhancement, exploration, reconstruction, and virtual museums. These technologies enable user-centred presentation and make cultural heritage digitally accessible, especially when physical access is constrained. A number of surveys of these emerging technologies have been conducted; however, they are either not domain specific or lack a holistic perspective in that they do not cover all the aspects of the technology. A review of these technologies from a cultural heritage perspective is therefore warranted. Accordingly, our article surveys the state-of-the-art in augmented-, virtual-, and mixed-reality systems as a whole and from a cultural heritage perspective. In addition, we identify specific application areas in digital cultural heritage and make suggestions as to which technology is most appropriate in each case. Finally, the article predicts future research directions for augmented and virtual reality, with a particular focus on interaction interfaces and explores the implications for the cultural heritage domain.

Abstract: During the last few years, there has been a growing exploitation of consumer-grade cameras allowing one to capture 360 images. Each device has different features and the choice should be entrusted on the use and the expected final output. The interest on such technology within the research community is related to its use versatility, enabling the user to capture the world with an omnidirectional view with just one shot. The potential is huge and the literature presents many use cases in several research domains, spanning from retail to construction, from tourism to immersive virtual reality solutions. However, the domain that could the most benefit is Cultural Heritage (CH), since these sensors are particularly suitable for documenting a real scene with architectural detail. Following the previous researches conducted by Fangi, which introduced its own methodology called Spherical Photogrammetry (SP), the aim of this paper is to present some tests conducted with the omni-camera Panono 360 which reach a final resolution comparable with a traditional camera and to validate, after almost ten years from the first experiment, its reliability for architectural surveying purposes. Tests have been conducted choosing as study cases Santa Maria della Piazza and San Francesco alle scale Churches in Ancona, Italy, since they were previously surveyed and documented with SP methodology. In this way, it has been possible to validate the accuracy of the new survey, performed by means an omni-camera, compared with the previous one for both outdoor and indoor scenario. The core idea behind this work is to validate if this new sensor can replace the standard image collection phase, speeding up the process, assuring at the same time the final accuracy of the survey. The experiment conducted demonstrate that, w.r.t. the SP methodology developed so far, the main advantage in using 360 omni-directional cameras lies on increasing the rapidity of acquisition and panorama creation phases. Moreover, in order to foresee the implications that a wide adoption of fast and agile tools of acquisition could bring within the CH domain, points cloud have been generated with the same panoramas and visualized in a WEB application, to allow a result dissemination between the users.

Abstract: Abstract This paper deals with the development of a geographic information system (GIS), specifically designed for the restoration process of Ascoli Satriano Fortress (an important example of military architecture in the south of Italy), using as entry data its 3D modelling obtained with a standard multi-view stereo (MVS) pipeline. The work described has been developed following a methodological approach, highlighting best practices for the management of different information and the creation of specific thematic maps, demonstrating how a close cooperation between restorers and geomatics experts can be the turnkey for the conservation process of the architectural heritage. In this research, the GIS implementation proposed for the cataloguing and the management of historical buildings serves to define the abacus of the materials and the decay analysis performed by restorers The aim is to create a link between the survey’s output and both quantitative/descriptive information, useful for managing the restoration process in all the steps of the work. The management of an historical building into an integrated system enables all the actors involved in the process to be as much faithful as possible with the real building features.

Abstract: A mosaic, made of small coloured tiles, called tesserae or tessellas, is a form of decorative art to create images and patterns on a surface. One of the first steps to obtain digital mosaics is the segmentation process to separate (identify) tesserae. Then, various tools are necessary to catalog the digitalized scenes, to extract the figures, such as animal or human beings, from the puzzle of small pieces, to geolocalize the segmented objects and to assign a semantic meaning to them. While some mosaic segmentation approaches have already been reported in the literature, currently, mosaic segmentation is still done by human operators, resulting time consuming and error prone. We propose in this paper an automatic approach, based on Deep Learning, to segment the mosaic floor tesserae of the church of S. Stephen in Umm ar Rasas. Our approach allows to obtain automatically and with good reliability the description of the main elements of a mosaic (the tesserae) that are not homogeneous. The experients performed on the collected tesserae dataset yield high accuracies and demonstrate the effectiveness and suitability of our approach.

Abstract: Surveying techniques have increased their pro- ductivity, improving the amount and the quality of Cultural Heritage data for documentation purposes. The reason of this improvement is twofold: on one hand, CH related researches gained more and more attention given the tremendous impor- tance they represent for the whole mankind. On the other, their knowledge and accurate documentation is urgent. Even if there are several acquisition techniques for each scale of representation, there is not still the winning solution for every condition; the consequence is that most of the surveying projects related to large and complex sites integrate multiple sensors and techniques [1]. Towards this direction, producers are introducing in the market sophisticated tools which integrates multiple sensors in an ”all in one solution” that in the literature are defined as combination of methods. One of them, recently introduced, is the SLAM (Simultaneously Localization and Mapping) technology, that has introduced a new system to acquire millions of 3D points in a short time and with good accuracy also in indoor location. In this light, the work that will be described in the article deals with the comparison of dense point clouds obtained with different acquisition techniques (namely TLS and Mobile Mapping), using as a case study a Roman Amphitheater, since, given its complexity, represents a challenging benchmark for such study. For a more detailed documentation of the site and to cope with the lack of imagery information from these latter techniques, a drone flight was performed. The main contributions of the article are: i) testing in a real case scenario a novel tool which integrates different sensors, assessing its suitability for archaeological settings; ii) validating its accuracy w.r.t. other well established techniques; iii) performing the complete mapping of an important ar- chaeological sites, combining terrestrial and aerial acquisition techniques.

Abstract: Today, museum visits are perceived as an opportunity for individuals to explore and make up their own minds. The increasing technical capabilities of Augmented Reality (AR) technology have raised audience expectations, advancing the use of mobile AR in cultural heritage (CH) settings. Hence, there is the need to define a criteria, based on users’ preference, able to drive developers and insiders toward a more conscious development of AR-based applications. Starting from previous research (performed to define a protocol for understanding the visual behaviour of subjects looking at paintings), this paper introduces a truly predictive model of the museum visitor’s visual behaviour, measured by an eye tracker. A Hidden Markov Model (HMM) approach is presented, able to predict users’ attention in front of a painting. Furthermore, this research compares users’ behaviour between adults and children, expanding the results to different kind of users, thus providing a reliable approach to eye trajectories. Tests have been conducted defining areas of interest (AOI) and observing the most visited ones, attempting the prediction of subsequent transitions between AOIs. The results demonstrate the effectiveness and suitability of our approach, with performance evaluation values that exceed 90%.

Senseable Spaces: from a theoretical perspective to the application in augmented environments
Autore/i: Pierdicca, Roberto
Editore: Università Politecnica delle Marche
Classificazione: 8 Tesi di dottorato
Abstract: Grazie all’ enorme diffusione di dispositivi senzienti nella vita di tutti i giorni, nell’ ultimo decennio abbiamo assistito ad un cambio definitivo nel modo in cui gli utenti interagiscono con lo spazio circostante. Viene coniato il termine Spazio Sensibile, per descrivere quegli spazi in grado di fornire servizi contestuali agli utenti, misurando e analizzando le dinamiche che in esso avvengono, e di reagire conseguentemente a questo continuo flusso di dati bidirezionale. La ricerca è stata condotta abbracciando diversi domini di applicazione, le cui singole esigenze hanno reso necessario testare il concetto di Spazi Sensibili in diverse declinazioni, mantenendo al centro della ricerca l’utente, con la duplice accezione di end-user e manager. Molteplici sono i contributi rispetto allo stato dell’ arte. Il concetto di Spazio Sensibile è stato calato nel settore dei Beni Culturali, degli Spazi Pubblici, delle Geosciences e del Retail. I casi studio nei musei e nella archeologia dimostrano come l’ utilizzo della Realtà Aumentata possa essere sfruttata di fronte a un dipinto o in outdoor per la visualizzazione di modelli complessi, In ambito urbano, il monitoraggio di dati generati dagli utenti ha consentito di capire le dinamiche di un evento di massa, durante il quale le stesse persone fruivano di servizi contestuali. Una innovativa applicazione di Realtà Aumentata è stata come servizio per facilitare l’ ispezione di fasce tampone lungo i fiumi, standardizzando flussi di dati e modelli provenienti da un Sistema Informativo Territoriale. Infine, un robusto sistema di indoor localization è stato istallato in ambiente retail, per scopi classificazione dei percorsi e per determinare le potenzialità di un punto vendita. La tesi è inoltre una dimostrazione di come Space Sensing e Geomatica siano discipline complementari: la geomatica consente di acquisire e misurare dati geo spaziali e spazio temporali a diversa scala, lo Space Sensing utilizza questi dati per fornire servizi all’ utente precisi e contestuali.

Abstract: In 2010, just before the war, professor Fangi made a trip in Syria and it was the occasion to make a fast documentation of some Syrian Cultural Heritage monuments. Most of the images were not taken properly to make a survey, but rather as a photographic report. Nevertheless, the images represent an important source of data, which can be processed in a rigorous manner, following the 4x4 CIPA rules, to obtain a 3D modelling by Spherical Photogrammetry. These surveys could be useful in case of reconstruction and in case of lack of a suitable alternative of metric documentation. Then, with the realization of an open access database it was possible to organize and collect all available data information supporting the documentation and preservation of Syrian monuments, sites and identities, and finally to share this documentation on different web platform.

Abstract: The use of 3D models to document archaeological ndings witnessed to boost in the latest years, mainly thanks to the large adop- tion of digital photogrammetry for the virtual reconstruction of ancient artifatcs. For this reason, the widespread availability of digital 3D objects obliges the research community to face with a hard challenge: which is the best way for allowing visitors being in contact with the real estate of cultural goods? The work described in these pages answers to these questions by describing a novel solution for the enhanced interaction and visualization of a complex 3D model . The installation consists in an autostereoscopic display paired with a remotely connected (with a wired connection) touch-pad for the interaction with the contents displayed in it. The main advantage of using such technology is represented by the fact that one is not obliged to wear cumbersome devices but at the same time one can have a 3D view of the object without any additional aid. The system allows, through a touch-pad, to manage the 3D views and interact with with a very small object that in its virtual dimension is magnied with respect to a classical museum arrangement. The research results, applied to the real case exhibition presented, have proved the innovation and usability of the multimedia solutions, which required the use of complex hardware components and a tricky implementation of the whole software architecture. The digital disruption in the CH domain should be also entrusted in the use of advanced interfaces that at the same time are intuitive and usable interaction methods

Classificazione: 1 Contributo su Rivista
Abstract: The impressive hydraulic system built by the Assyrian King Sennacherib is composed by different archaeological areas, displaced along the Land of Nineveh, in Iraqi Kurdistan. The extensive project we are working on has the aim of mapping and geo-referencing any kind of documentation in order to design an archaeological-environmental park able to preserve and enhance the archaeological complex. Unfortunately, the area is failing a topographic documentation and the available cartography is not sufficient for planning and documentation purposes. The research work presented in these pages moves towards this direction, by exploiting Pleiadés Very High Resolution (VHR) images (in both nadir and stereo configuration) for an accurate mapping of the site. In more depth, Pleiadés nadir VHR images have been used to perform a pansharpening procedure used to enhance the visual interpretation of the study area, whilst stereo-pair have been processed to produce the Digital Elevation Model (DEM) of the study area. Statistical evaluations show the high accuracy of the processing and the reliability of the outputs as well. The integration of different products, at different Levels of Detail within a unique GIS environment, besides protecting, preserving and enhancing the water system of Sennacherib’s, paves the way to allow the Kurdistan Regional Government to present a proposal for the admission of the archaeological complex in the UNESCO World Heritage Tentative List (WHTL)

Abstract: The documentation of the archaeological heritage through 3D models to know ancient findings, has become a common practice within the international panorama. Using minimal hardware, as well as its ease of use in almost every environmental condition, make 3D sampling solutions based on Multiple View Stereo (MVS) matching and Structure from Motion techniques ideal for on-site documentation of excavations or emergencies. Moreover, the availability of inexpensive platforms for web-based visualization represents great benefit in the field of archaeology, where generally the low budged and the limitation of more complex instruments are a must. The case study presented in these pages, experienced in Petra, Jordan, moves towards this direction. In the close proximity of the El- Khasneh fac¸ade, is situated an excavation where two entrance, well preserved, give access to the Tomb of Pharaoh. The documentation described in these pages has the twofold objective of providing the research community with a priceless dataset, acquired for one of the most important heritage of the world that is partially still unknown and to share on line these computations. This work confirms how cultural heritage documentation and dissemination of architectural rests, that are important for tourism and their interactive visualization, can strongly benefit from the creation of 3D models and their sharing on the web. This particular archaeological setting is an interesting base for investigation, given the complexity of the structure and its precarious condition.

Abstract: The digitization of complex buildings, findings or bas relieves can strongly facilitate the work of archaeologists, mainly for in depth analysis tasks. Notwithstanding, whether new visualization techniques ease the study phase, a classical naked-eye approach for determining changes or surface alteration could bring towards several drawbacks. The research work described in these pages is aimed at providing experts with a workflow for the evaluation of alterations (e.g. color decay or surface alterations), allowing a more rapid and objective monitoring of monuments. More in deep, a pipeline of work has been tested in order to evaluate the color variation between surfaces acquired at different ´epoques. The introduction of reliable tools of change detection in the archaeological domain is needful; in fact, the most widespread practice, among archaeologists and practitioners, is to perform a traditional monitoring of surfaces that is made of three main steps: production of a hand-made map based on a subjective analysis, selection of a sub-set of regions of interest, removal of small portion of surface for in depth analysis conducted in laboratory. To overcome this risky and time consuming process, digital automatic change detection procedure represents a turning point. To do so, automatic classification has been carried out according to two approaches: a pixel-based and an object-based method. Pixel-based classification aims to identify the classes by means of the spectral information provided by each pixel belonging to the original bands. The object-based approach operates on sets of pixels (objects/regions) grouped together by means of an image segmentation technique. The methodology was tested by studying the bas-relieves of a temple located in Peru, named Huaca de la Luna. Despite the data sources were collected with unplanned surveys, the workflow proved to be a valuable solution useful to understand which are the main changes over time.

Abstract: Chan Chan, an archaeological site located at Trujillo, Peru, is a huge historical settlement very large and difficult to visit and some well-conserved architecture, like Huaca Arco Iris, is very far from the core centre of the site. Furthermore many other heavy factors, as illegal excavations, marine salt transported by the wind and the sometime devastating phenomenon of the Ninõ, are the reasons of the lost of many decorative elements, which are covered due to conservation issues. To overcome the aforesaid problems, we designed, developed and realized the museum exhibition called “Esquina Multimedia”, providing the tourists with interactive and enjoyable applications. An Augmented Reality application has been developed in order to discover ancient artefacts that are invisible because covered by the earth (or by protection structures). A web-browser has been specifically designed to show bas-relieves, with HD visualization and with anaglyph stereoscopic view. Herewith, a wall-mounted panel representing a metric 3D reconstruction by an accurate survey of the building helps the user to find the artefact position.

Classificazione: 1 Contributo su Rivista
Abstract: Chan Chan is a wide archaeological site located in Peru. Its knowledge is limited to the visit of Palacio Tschudi, the only restored up to now, whilst the majority of the site remains unknown to the visitors. The reasons are manifold. The site is very large and difficult to visit. Some well-conserved architectures, such as Huaca Arco Iris, are very far from the core centre. Furthermore, there are heavy factors of decay, mainly caused by illegal excavations, by marine salt and by the devastating phenomenon of El Niño. For these reasons, the majority of the decorative elements are protected by new mud brick walls. Finally, the vastness of the buildings makes difficult to understand their real value, even through a direct visit of the site. In order to overcome the aforesaid problems, we designed, developed and realized the museum exhibition presented in this paper. We named Esquina Multimedia an installation where every corner is aimed to solve a specific problem, providing the tourists with interactive and enjoyable applications. The virtual tour allows reaching also the unreachable areas. An Augmented Reality (AR) application has been developed in order to show ancient artefacts covered by the earth. A web-browser has been specifically designed to show bas-reliefs, with HD visualization, anaglyph stereoscopic view and a 3D virtual model of both the structures and the bas-reliefs. At the same time, a wall-mounted panel representing a metric 3D reconstruction of the building helps the user to find the artefact position. Descriptions of the hardware components and of the software details are presented, with particular focus regarding the implementation of the application, arguing how the digital approach could represent the only answer towards a full exploitation of archaeological sites. The paper also deals with the implementation of a web tool, specifically designed to display and browse 3D-Models.

Abstract: The main aim of this work is to rise the challenge of relentless growth of digital technologies into our daily life. Smart phones, smart watches, tablets, etc and Internet have become common tools is several fields of human activities, connecting, guiding, informing, and in a last stance making people interconnected and informed. Public open spaces (POS) (such as, parks, gardens, squares, plazas) would greatly benefit by this growing availability of relevant geolocated information. Therefore, our aim is to unfold two main questions: how can we use digital technologies to attract people to spend more time outdoors for a more active lifestyle; and what opportunities technology opens to increase knowledge about users and uses of public open spaces? The discussion is backed by experience exchanges carried out within the Cyberparks Project and articulates around the ICT potential to enhance communication among (potential) users, transforming public open spaces production an interactive process. Such improved interactivity, on a turn, enables creative community participation, empowerment and capacity building. Besides a discussion on the mobile technology for human interaction with spaces, this paper presents an overview of the possible technological benefits for users, policy makers, practitioners and planners.

DIGITAL APPLICATIONS IN ARCHAEOLOGY AND CULTURAL HERITAGE

Classificazione: 1 Contributo su Rivista
Abstract: Currently, the use of 3D digital acquisition techniques represents the most popular means for the documentation and digitization of archaeological heritage. The advantage of recreating a detailed virtual model of a site is twofold. On the one hand, it provides a support for archaeologists who deal with continuous work of restoration and their associated studies. In fact, the majority of the sites are made of perishable materials, making essential the adoption of fast tool for data acquisition. On the other hand, the different medium of visualization reaches the wider public directly, improving the spread of Cultural Heritage artefacts. The reality-based representation may not be sufficient by itself to convey all the information about a site. We therefore propose an integrated approach based upon a combination of different 3D acquisition techniques for virtual reconstruction of a complex archaeological building. In this paper, a methodology for a low cost acquisition, processing and visualization of data is presented. The aim of this work is to describe a complete workflow for virtual reconstruction, from the acquisition to the model visualization, by integrating spherical photogrammetry and dense reconstruction techniques. This allows one to obtain a model that is metrical and accurate at the same time. Details of the final virtual reconstruction demonstrate the validity of the pipeline. The methodology has been experimented on a typical building called Huaca Arco Iris, situated into the complex of Chan Chan site, an UNESCO archaeological area in Peru. � 2016

Abstract: Latest improvement on mobile devices capabilities definitively changed the way people experience their surroundings. Thanks to the improvement of built in sensors, devices are able to sense the environment at users’ location. The ability to provide contextual services to the visitors is a key aspect to make public parks more accessible, comprehensible end enjoyable. The paper outlines the application of Augmented Reality technologies in a real case scenario. The aim is to equip visitors with an ICT tool able to enhance their perception visiting open spaces and parks. The reporting area chosen for the study case is an Archaeological park, the Cardeto, located within an urban green open space in the outskirts of Ancona, a city in central Italy. Ensuring the success of the experiment has required an hybrid approach, with the main objective of providing visitors with an endless flow of information, anytime and anywhere. To reach this result, a mobile application has been developed, exploiting two different tracking systems: location-based and edge-based. The first one helps users to move along with a network of given Points of Interest disseminated within the park. At the same time, the second system displays a rich set of information each time a user came in close the proximity with artefacts or valuable heritages. This work is part of a wider ongoing project aiming at a better understanding of the potentials inherent the design space for smartphones in context-aware AR applications for tourists. Our experiment demonstrates the validity of purposed methodology as a promising solution for Cultural Heritage purposes.

Abstract: Linear buffer strips (BS) along watercourses are commonly adopted to reduce run-off, accumulation of bank-top sediments and the leaking of pesticides into fresh-waters, which strongly increase water pollution. However, the monitoring of their conditions is a difficult task because they are scattered over wide rural areas. This work demonstrates the benefits of using a standard data layer and Augmented Reality (AR) in watershed control and outlines the guideline of a novel approach for the health-check of linear BS. We designed a mobile environmental monitoring system for smart maintenance of riverbanks by embedding the AR technology within a Geographical Information System (GIS). From the technological point of view, the system's architecture consists of a cloud-based service for data sharing, using a standard data layer, and of a mobile device provided with a GPS based AR engine for augmented data visualization. The proposed solution aims to ease the overall inspection process by reducing the time required to run a survey. Indeed, ordinary operational survey conditions are usually performed basing the fieldwork on just classical digitized maps. Our application proposes to enrich inspections by superimposing information on the device screen with the same point of view of the camera, providing an intuitive visualization of buffer strip location. This way, the inspection officer can quickly and dynamically access relevant information overlaying geographic features, comments and other contents in real time. The solution has been tested in fieldwork to prove at what extent this cutting-edge technology contributes to an effective monitoring over large territorial settings. The aim is to encourage officers, land managers and practitioners toward more effective monitoring and management practices

Abstract: Museums and art galleries are called to preserve and promote their collections. Mobile technologies like Augmented Reality would transform visitors from passive observers to protagonists, creating engaging and personal art experience for the audience. However, the hurdles preventing Augmented Reality from becoming a widespread medium to convey virtual information about the Cultural Heritage, lies in the limitations in adopting fast and agile tools of development. The paper presents an ongoing research, aimed at the creation of a framework to serialize the development of Augmented Reality application, based on a standard data layer. The core of the application is designed to augment artworks, while the standardization of data will permit a fast multi-app development. This framework is useful to bridge the gap between designers and developers, and will facilitate a semi-automatic development of Augmented Reality applications for Cultural Institutions.

Abstract: The exploitation of high quality 3D models for dissemination of archaeological heritage is currently an investigated topic, although Mobile Augmented Reality platforms for historical architecture are not available, allowing to develop low-cost pipelines for effective contents. The paper presents a virtual anastylosis, starting from historical sources and from 3D model based on TLS survey. Several efforts and outputs in augmented or immersive environments, exploiting this reconstruction, are discussed. The work demonstrates the feasibility of a 3D reconstruction approach for complex architectural shapes starting from point clouds and its AR/VR exploitation, allowing the superimposition with archaeological evidences. Major contributions consist in the presentation and the discussion of a pipeline starting from the virtual model, to its simplification showing several outcomes, comparing also the supported data qualities and advantages/disadvantages due to MAR and VR limitations.

Abstract: The huge potential of 3D digital acquisition techniques for the documentation of archaeological sites, as well as the related findings, is almost well established. In spite of the variety of available techniques, a sole documentation pipeline cannot be defined a priori because of the diversity of archaeological settings. Stratigraphic archaeological excavations, for example, require a systematic, quick and low cost 3D single-surface documentation because the nature of stratigraphic archaeology compels providing documentary evidence of any excavation phase. Only within a destructive process each single excavation cannot be identified, documented and interpreted and this implies the necessity of a re- examination of the work on field. In this context, this paper describes the methodology, carried out during the last years, to 3D document the Early Neolithic site of Portonovo (Ancona, Italy) and, in particular, its latest step consisting in a photogrammetric aerial survey by means of UAV platform. It completes the previous research delivered in the same site by means of terrestrial laser scanning and close range techniques and sets out different options for further reflection in terms of site coverage, resolution and campaign cost. With the support of a topographic network and a unique reference system, the full documentation of the site is managed in order to detail each excavation phase; besides, the final output proves how the 3D digital methodology can be completely integrated with reasonable costs during the excavation and used to interpret the archaeological context. Further contribution of this work is the comparison between several acquisition techniques (i.e. terrestrial and aerial), which could be useful as decision support system for different archaeological scenarios. The main objectives of the comparison are: i) the evaluation of 3D mapping accuracy from different data sources, ii) the definition of a standard pipeline for different archaeological needs and iii) the provision of different level of detail according to the user needs.

Abstract: Eye-tracking technology is becoming easier and cheaper to use, resulting in its increasing application to numerous fields of research. Recent years have seen rapid developments in this area. In light of the foregoing, in the context of Cultural Heritage (CH), the definition of a modern approach to understand how individuals perceive art is challeng- ing. Despite the art perception is highly subjective and variable according to knowledge and experience, more recently, several scientific study and enterprises started to quantify how subjects observe art by the applica- tion of the eye-tracking technology. The aim of this study was to under- stand the visual behaviour of subjects looking at paintings, using eye- tracking technology, in order to define a protocol for optimizing an exist- ing Augmented Reality (AR) application that allows the visualization of digital contents through a display. The stimuli used are three famous paintings preserved at the National Gallery of Marche (Urbino, Marche Region, Italy). We applied eye-tracking to have a deeper understanding of people visual activities in front of these paintings and to analyse how digital contents eventually influence their behaviour. The description of the applied procedure and the preliminary results are presented.

Abstract: In this paper we present a methodological workflow developed within the "ArcheoFano" project, improving collection, organization and management of a GIS data structure for the urban-archaeological Roman centre of Fano town. In this context, the proposed methodology is aimed to build up an integrated and multipurpose system. The starting point is data collection by means of archival (for documentation purposes) and highresolution survey techniques (for metrical purposes); afterwards, a conceptual data model organizes archaeological data and realizes an easily updating solution that automatically produce short reports to share with the users. The open source QGIS is used to develop the spatial extension with the aim to manage 2D/3D numerical cartography and detailed 3D model (using open tools such as Virtual Terrain and Enviro). The final geo-database contains all the useful information to support urban planners decision-making. The ability to structure data in a maintainable way helps to ensure cross-disciplinary cooperation in the management and protection of heritage resources. Lastly, an Augmented Reality (AR) experience is carried out. Linked directly to the geo-database, AR allows a quick real time visualization of GIS layers and 3D models, showing the way forward smart tourism and virtual museum applications. This technology is needful when the archaeological findings must be conceived due to conservation issues.

Abstract: In archaeology, findings are completely freed from the earth which had been covering for centuries but in most cases they must be cov- ered again in order to protect them. In this paper we present a augmented reality (AR) experience for the visualization of 3D models in-situ, giv- ing the possibility to see conceived findings. The experience was carried out for archaeological purposes in Chan Chan, the America’s greatest pre-Columbian town. From 2001, our mission is operating at Chan Chan carrying on a wide action of documentation, conservation and exploita- tion. We propose an interesting workflow: image acquisition, 3D pho- togrammetric reconstruction, 3D simplification, AR visualization. Also a knowledge base applied to archaeological sites is here presented.

Classificazione: 1 Contributo su Rivista
Abstract: This paper presents results of a research project “dUcale” that experiments ICT solutions for the museum of Palazzo Ducale (Urbino). In this project, the famed painting the “Citt`a Ideale” becomes a case to exemplify a specific approach to the digital mediation of cultural heritage. An augmented reality (AR) mobile application, able to enhance the museum visit experience, is presented. The computing technologies involved in the project (websites, desktop and social applications, mobile software, and AR) constitute a persuasive environment for the artwork knowledge. The overall goal of our research is to provide to cultural institutions best practices efficiently on low budgets. Therefore, we present a low cost method for high-resolution acquisition of paintings; the image is used as a base in AR approach. The proposed methodology consists of an improved SIFT extractor for real time image. The other novelty of this work is the multipoint probabilistic layer. Experimental results demonstrated the robustness of the proposed approach with extensive use of the AR application in front of the “Citt`a Ideale” painting. To prove the usability of the application and to ensure a good user experience, we also carried out several users tests in the real scenario.
