Item 3D Digitizing and Visualizing a Prehistoric Portable Art Object: a 12,000 Years Old "Bâton Percé"(The Eurographics Association, 2010) Subsol, Gerard; Bourdin, Pierre; Duranthon, Francis; Braga, J.; Alessandro Artusi and Morwena Joly and Genevieve Lucet and Denis Pitzalis and Alejandro RibesIn this paper, we present some results on 3D digitizing and visualizing a prehistoric portable art object. This 12,000 years old artifact was scanned with a surface scanner and with two volume scanners. With this last device, we can reach a high resolution which allows one to distinguish the engravings. It is not so easy to visualize and interact in 3D with such a complex object and we describe a framework composed of a stereoscopic visualization system coupled with a low-cost tangible interface based on a Wiimote.Item 3D Pipeline from Data Acquisition to Data Visualization of the Hellenistic-Roman Theatre of Paphos(The Eurographics Association, 2010) Gabrielli, Roberto; D'Andrea, Andrea; Angelini, Andrea; Amico, Nicola; Iannone, Giancarlo; Georgiou, Ropertos; Alessandro Artusi and Morwena Joly and Genevieve Lucet and Denis Pitzalis and Alejandro RibesIn this paper is described the fusion of two different technologies for the three dimensional acquisition of the Hellenistic-Roman Theatre of Paphos located at the island of Cyprus. A laser scanner and an innovative device for the aerial photogrammetry have been used for this purpose. Despite the size of the archaeological site and the complexity of the survey; it has been possible in a short time to acquire the whole theatre using photogrammetric and laser scanning techniques. The final result is the complete 3D model of the theatre at present, which was used for 3D stereoscopic vision simulation.Item 3D Reconstruction of Archaeological Sites Using Photogrammetry(The Eurographics Association, 2010) Dutailly, Bruno; Mora, Pascal; Vergnieux, Robert; Alessandro Artusi and Morwena Joly and Genevieve Lucet and Denis Pitzalis and Alejandro RibesThe 3D reconstructionof an archaeological site is a difficult task, taking into account the available documentation. Our team, supported by the TGE Adonis, is specialized in 3D reconstruction and conservation of 3D data. We already use numerous sources, like excavation documentation, ancient texts, any kind of representation, land surveys, in-situ pictures, laser or time of flight scannography, and experiments of archaeologists, anthropologists and architects. Since the 80's, each model we produce are scientifically checked by specialists, and regularly updated to follow new knowledges and investigations. In this paper, we present the use of photogrammetry to reconstruct a 3D model of an archaeological site, as a new source of data, less expensive and more accessible than scanners.We present concrete cases: a chapel (12 century p.C., Moissac, France), catacombs of St Pierre et Marcellin (250 p.C., Rome, Italy) and a roman coin (5 a.C., Loron, Croatia). The question of scale and texture mapping is explored through the software like photomodeler and PMVS. Finaly, we discuss the accuracy of photogrammetry in comparison to scanners, the accessibility of this technique to archaeologists, and the interest for fragile artefacts in museums.Item 3D-Digitization of the ''Wild Goat'' Vases(The Eurographics Association, 2010) Kolin, David; Joly, Morwena; Alessandro Artusi and Morwena Joly and Genevieve Lucet and Denis Pitzalis and Alejandro RibesThe wild-goat vases are a style of Greek vases that have been crafted between the 7th and 6th century BC. The 3D-digitization of these vases has been ongoing at the C2RMF for a few years now. Different scanning techniques have been used, and the latest and most effective, is through the use of a NextEngine camera. The aim of this project is to help curators to digitally analyse the vases, compare their shape and colours, and monitor their state through time.Item Architectural 3D Modeling for a 3D GIS Web-Based System(The Eurographics Association, 2010) Apollonio, Fabrizio I.; Gaiani, Marco; Baldissini, Simone; Alessandro Artusi and Morwena Joly and Genevieve Lucet and Denis Pitzalis and Alejandro RibesWe describes a 3D GIS system entirely founded on Google Earth (GE), designed to make available on this platform high-quality 3D models of one of the architect Andrea Palladio, conceived as a metaphor for navigating through the data and developed as a scalable applications able to allow the use of the same database for different user simply filtering the data according to the specific requirements.Item Automation in Multi-Image Spherical Photogrammetry for 3D Architectural Reconstructions(The Eurographics Association, 2010) Barazzetti, Luigi; Fangi, Gabriele; Remondino, Fabio; Scaioni, Marco; Alessandro Artusi and Morwena Joly and Genevieve Lucet and Denis Pitzalis and Alejandro RibesThe derivation of 3D metric information from spherical images for interactive exploration and realistic 3D modeling is receiving great attention due to their high-resolution content, large field-of-view, lowcost, easiness, rapidity and completeness. We present a methodology for accurate 3D reconstruction from spherical (panoramic) images acquired by mosaicking separated frame images captured with a rotating head and a consumer grade or SLR digital camera. In particular we focus the attention on the orientation of the panoramas which is achieved by extracting the necessary tie points with a new fully automated procedure, based on feature matching and robust estimators. Results of the automated panorama orientations and 3D reconstructions of architectural scenes are presented and discussed.Item A Blender Open Pipeline for a 3D Animated Historical Short Film(The Eurographics Association, 2011) Ponti, Francesca Delli; Guidazzoli, Antonella; Imboden, Silvano; Liguori, Maria Chiara; Franco Niccolucci and Matteo Dellepiane and Sebastian Pena Serna and Holly Rushmeier and Luc Van Gool''APA and the History of Bologna'' is the first 3D stereo movie made with Blender according to high philological standards and related to the history of an entire city with four different geo-referenced historical digital terrain models and several scenarios, from the Etruscan up to the present day. The methodology developed for this realisation, centered on open source and interdisciplinary framework, has been of great help in this endeavour.Item Browsing Historical Pompeian Watercolours Through a Google Earth-based Meta Interface: Luigi Bazzani's Exhibition(The Eurographics Association, 2012) Coralini, A.; Guidazzoli, Antonella; Liguori, Maria Chiara; Baglivo, A.; Spigarolo, Micaela; David Arnold and Jaime Kaminski and Franco Niccolucci and Andre StorkA Google-Earth-based meta interface provides the traditional text-based access to cultural repo DB with an easy and quick way for gaining insight into the full available data. Developed at Cineca for the Department of History and Human Cultures - Bologna University - the interface is proving its flexibility with this case of re-use as a support to an up - coming exhibition about watercolours realized at Pompeii at the turn of XIX century.Item Cloud-based 3D Reconstruction of Cultural Heritage Monuments using Open Access Image Repositories(The Eurographics Association, 2014) Hadjiprocopis, Andreas; Wenzel, Konrad; Rothermel, Mathias; Ioannides, Marinos; Fritsch, Dieter; Klein, Michael; Johnsons, Paul S.; Weinlinger, Guenther; Doulamis, Anastasios; Protopapadakis, Eftychios; Kyriakaki, Georgia; Makantasis, Kostas; Fellner, Dieter W.; Stork, Andre; Santos, Pedro; Reinhard Klein and Pedro SantosA large number of photographs of cultural heritage items and monuments is publicly available in various Open Access Image Repositories (OAIR) and social media sites. Metadata inserted by camera, user and host site may help to determine the photograph content, geo-location and date of capture, thus allowing us, with relative success, to localise photos in space and time. Additionally, developments in Photogrammetry and Computer Vision, such as Structure from Motion (SfM), provide a simple and cost-effective method of generating relatively accurate camera orientations and sparse and dense 3D point clouds from 2D images. Our main goal is to provide a software tool able to run on desktop or cluster computers or as a back end of a cloud-based service, enabling historians, architects, archaeologists and the general public to search, download and reconstruct 3D point clouds of historical monuments from hundreds of images from the web in a cost-effective manner. The end products can be further enriched with metadata and published. This paper describes a workflow for searching and retrieving photographs of historical monuments from OAIR, such as Flickr and Picasa, and using them to build dense point clouds using SfM and dense image matching techniques. Computational efficiency is improved by a technique which reduces image matching time by using an image connectivity prior derived from low-resolution versions of the original images. Benchmarks for two large datasets showing the respective efficiency gains are presented.Item Combining 3D Technologies in the Field of Cultural Heritage: Three Case Studies(The Eurographics Association, 2011) Antlej, Kaja; Eric, Miran; avnik, Mojca; upanek, Bernarda; Slabe, Janja; Battestin, B. Borut; Franco Niccolucci and Matteo Dellepiane and Sebastian Pena Serna and Holly Rushmeier and Luc Van GoolThe advantages of 3D technologies (3D digitisation, visualisation, 3D printing...) are recognised by various professions in the field of cultural heritage (CH). Today these technologies have been technologically improved to the point that allows them to be merged for different purposes. The paper presents projects related to the successful combining of these technologies with regard to CH. In three case studies we discuss processes using 3D technologies for documenting and presenting artefacts, 3D collection by the Digital Library of Slovenia and directly using techology for the restoration of museum object. Although all the examples under discussion show how these tools and processes can be used for different purposes and applications in the area of CH.Item Community-driven Generation of 3D and Augmented Web Content for Archaeology(The Eurographics Association, 2014) Ritsos, Panagiotis D.; Wilson, Andrew T.; Miles, Helen C.; Williams, Lee F.; Tiddeman, Bernard; Labrosse, Frédéric; Griffiths, Seren; Edwards, Ben; Möller, Katharina; Karl, Raimund; Roberts, Jonathan C.; Reinhard Klein and Pedro SantosHeritage sites (such as prehistoric burial cairns and standing stones) are prolific in Europe; although there is a wish to scan each of these sites, it would be time-consuming to achieve. Citizen science approaches enable us to involve the public to perform a metric survey by capturing images. In this paper, discussing work-in progress, we present our automatic process that takes the user's uploaded photographs, converts them into 3D models and displays them in two presentation platforms - in a web gallery application, using X3D/X3DOM, and in mobile augmented reality, using awe.js.Item Connecting Information as Navigation Paths for Exploring Digital Video Collections(The Eurographics Association, 2011) Damnjanovic, Uros; Hermon, Sorin; Franco Niccolucci and Matteo Dellepiane and Sebastian Pena Serna and Holly Rushmeier and Luc Van GoolThe way information is presented to users is of great importance in today's digital world. This is especially true for data collections that are rich in information that is not always easily understood. In this paper we present a solution for accessing digital video collections using specially created interfaces for data exploration. We developed a data navigation model that is used to establish links between data records and created different webbased tools for using these connections as paths that users can follow in their exploration of the content. We argue that by providing a set of interactive tools for data exploration we can increase the amount of information that is passed from data to users. We show how different interface solutions for accessing informative digital collections can be used to improve users experience of exploring the data and help them make effective use of acquired information.Item Content-based Retrieval of 3D Models using Generative Modeling Techniques(The Eurographics Association, 2014) Grabner, Harald; Ullrich, Torsten; Fellner, Dieter W.; Reinhard Klein and Pedro SantosIn this paper we present a novel 3D model retrieval approach based on generative modeling techniques. In our approach generative models are created by domain experts in order to describe 3D model classes. These generative models span a shape space, of which a number of training samples is taken at random. The samples are used to train content-based retrieval methods. With a trained classifier, techniques based on semantic enrichment can be used to index a repository. Furthermore, as our method uses solely generative 3D models in the training phase, it eliminates the cold start problem. We demonstrate the effectiveness of our method by testing it against the Princeton shape benchmark.Item Conveying Archaeological Contexts to Museum Visitors: Case Study Pergamon Exhibition(The Eurographics Association, 2012) Klindt, Marco; Prohaska, Steffen; Baum, Daniel; Hege, Hans-Christian; David Arnold and Jaime Kaminski and Franco Niccolucci and Andre StorkReconnecting the audience of an exhibition to the archaeological context of ancient artefacts and explaining their reception histories is a great challenge. Employing digital devices to support the understanding of connections between exhibits and their past, creates the additional challenge of developing a system that not only achieves comprehension but is also accessible to all museum visitors. We have devised a concept and an implementation of a kiosk application for conveying these contexts and evaluated the effectiveness in a special exhibition about the ancient city of Pergamon. We found that using postcards that are accessible through different navigation views as the central metaphor is an effective way for museum visitors to interact with and to spent time exploring contexts about exhibits.Item Critical Review of 3d Digitization Methods and Techniques Applied to the Field of Architectural Heritage: Methodological and Cognitive Issues(The Eurographics Association, 2011) Buglio, David Lo; Luca, Livio De; Franco Niccolucci and Matteo Dellepiane and Sebastian Pena Serna and Holly Rushmeier and Luc Van GoolThis article concentrates on the epistemological aspects of architectural survey. It offers a critical observation of the technologies used in the field of 3D digitization. More specifically, the study evaluates the way in which the tools and methods used for the acquisition and representation of the data do or do not contribute to the enhancement of architectural knowledge. To understand the relationships between technology and knowledge transfer, we will carry out an observation based on a series of case studies. This is intended to highlight a dual issue of a cognitive nature: the first, perceptual, refers to the comprehension of the object and the second, descriptive, refers to the intelligibility of the 3D information model. This reflexive approach is justified by the fact that the main technological advances rarely compensate the methodological deficiencies encountered. Finally, this article offers perspectives for the in-depth study of all the cognitive mechanisms involved in the architectural survey.Item DC-NET: The Establishment of the Digital Cultural Heritage Network(The Eurographics Association, 2010) Francesco, Giuliana De; Alessandro Artusi and Morwena Joly and Genevieve Lucet and Denis Pitzalis and Alejandro RibesCore concern of the DC-NET project is to develop and to strengthen the coordination of public research programmes in the sector of Digital Cultural Heritage across Europe and to raise awareness of the possibilities offered by e-Infrastructures to help carry out advanced research programmes. The Network of Common Interest established by DC-NET will provide the forum for coordination. DC-NET Network will agree a set of common priorities for digital cultural heritage research and will work with e-Infrastructures providers to identify how best to carry out this research using the National Research and Education Networks, GRID and other eInfrastructures. A Joint Activities Plan for e-Infrastructure-enabled research in digital cultural heritage will be generated and initiated. This work will pave the way to a series of innovative initiatives and the creation of Virtual Research Communities active in the digital cultural heritage research, powered by access to e-InfrastructuresItem Defixio Digital(is): A Semantic-enabled Digital Archive For the Study of Ancient Curse Tablets(The Eurographics Association, 2011) Felicetti, Achille; Murano, Francesca; Franco Niccolucci and Matteo Dellepiane and Sebastian Pena Serna and Holly Rushmeier and Luc Van GoolIn this paper we present a relevant example of how new technologies can be applied to the study of the ancient world. In particular, we present a set of activities whereby we apply semantic technologies and open source software for the study of a very specific class of archaeological and textual objects, the so-called defixiones. The term defixio refers to a cursing tablet, engraved on thin sheets of lead, especially as used in the Ancient Mediterranean area for various "magical" uses. The study of this field has not yet produced any complete systematisation of all the different material and interpretations. We intend developing a system bringing together all the existing information in order to offer scholars a tool comprising all available knowledge to date and the possibility to extend it with the results of their research.Item Dense Point Cloud Acquisition via Stereo Matching Applied to: the Kilwa Archaeological Site and the Gallo-Roman Theatre of Mandeure(The Eurographics Association, 2010) Hullo, Jean-François; Grussenmeyer, Pierre; Assali, Pierre; Smigiel, Eddie; Alessandro Artusi and Morwena Joly and Genevieve Lucet and Denis Pitzalis and Alejandro RibesIn this paper, we present a methodology for Dense Stereo Matching (DStM) acquisition and processing. Two main applications are detailed. In our application sites, many constraints led us to choose DStM. In the archaeological site of the Gallo-Roman Theatre of Mandeure (France), a initial terrestrial laser scanning campaign had to be completed with patches acquired from DStM because of the site geometric complexity. In the epigraphic and archaeological site of the region of Kilwa (Saudi Arabia), we applied DStM for both prospecting and excavating. We distinguished two kinds of applications in the paper: 1 to 5 stereopairs and 5 to 30 stereopairs. We inserted the data of both kind of cases into larger datasets. These datasets are currently used for archaeological reconstruction purposes of as-built buildings.Item Detection and Classification of Petroglyphs in Gigapixel Images -- Preliminary Results(The Eurographics Association, 2011) Seidl, Markus; Breiteneder, Christian; Franco Niccolucci and Matteo Dellepiane and Sebastian Pena Serna and Holly Rushmeier and Luc Van GoolWith the advances of digital photography, the number of high quality images of rock panels containing petroglyphs grows steadily. Different time-consuming manual methods to determine and document the exact shapes and spatial locations of petroglyphs on a panel have been carried out over decades. We aim at automated methods to a) segment rock images with petroglyphs, b) classify the petroglyphs and c) retrieve similar petroglyphs from different archives. In this short paper, we present an approach for the unsolved problem of rock art image segmentation. A first evaluation demonstrates promising results.Item Evaluating the Curvature Analysis as a Key Feature for the Semantic Description of Architectural Elements(The Eurographics Association, 2014) Adrian, Julie; Buglio, David Lo; Luca, Livio De; Reinhard Klein and Pedro SantosThe recent developments in the fields of photogrammetry and laser scanning, have made possible mass acquisitions of heritage artifacts with a particularly high level of geometric accuracy. A processing of the digital model will be necessary to isolate some characteristics in order to carry on an analysis of the architectural object. In this poster, the potentialities of the curvature maps, extracted from digital acquisitions, are defined to conduct the study on the morphology of architectural elements. The current work focuses on the technical and theoretical issues that will ultimately result in an average surface signature. This will allow to identify the degree of remoteness of each attribute.
