The development of close-range photogrammetry has produced a lot of new possibility to study cultural heritage. 3D data acquired with conventional and low cost cameras can be used to document, investigate the full appearance, materials and conservation status, to help the restoration process and identify intervention priorities. At the same time, with 3D survey a lot of three-dimensional data are collected and analyzed by researchers, but there are a very few possibility of 3D output. The augmented reality is one of this possible output with a very low cost technology but a very interesting result. Using simple mobile technology (for iPad and Android Tablets) and shareware software (in the case presented “Augment”) it is possible to share and visualize a large number of 3D models with your own device. The case study presented is a part of an architecture graduate thesis, made in Rome at Department of Architecture of Roma Tre University. We have developed a photogrammetric survey to study the Aurelian Wall at Castra Praetoria in Rome. The surveys of 8000 square meters of surface have allowed to identify stratigraphy and construction phases of a complex portion of Aurelian Wall, specially about the Northern door of Castra. During this study, the data coming out of 3D survey (photogrammetric and topographic), are stored and used to create a reverse 3D model, or virtual reconstruction, of the Northern door of Castra. This virtual reconstruction shows the door in the Tiberian period, nowadays it's totally hidden by a curtain wall but, little and significative architectural details allow to know its original feature. The 3D model of the ancient walls has been mapped with the exact type of bricks and mortar, oriented and scaled according to the existing one to use augmented reality. Finally, two kind of application have been developed, one on site, were you can see superimposed the virtual reconstruction on the existing walls using the image recognition. On the other hand, to show the results also during the graduation day, the same application has been created in off-site condition using a poster.

<p>Everyone knows the importance of new technologies and the growth they have had in mobile devices. Today in the field of study and dissemination of cultural heritage (including archaeological), the use of digital 3D models and associated technologies are a tool to increase the registration quality and consequently a better basis for interpretation and dissemination for cultural tourism, education and research. Within this area is gaining positions photogrammetry over other technologies due to its low cost. We can generate 3D models from forografí as through a set of algorithms that are able to obtain very approximate models and very realistic textures. In this paper we propose the use of game-engines to incorporate one element diffusion: the ability to navigate the 3D model realistically. As a case study we use a Menga dolmen that will serve as a study and demonstration of the techniques employed. </p>

The Riace Bronzes are two full-size bronzes cast around the 5th century BC, located at the ‘Museo Archeologico Nazionale della Magna Grecia’ in Reggio Calabria; they truly represent significant sculptural masterpieces of Greek art in the world due to their outstanding manufacture. This paper describes the methodology for the achievement of a 3D model of the two sculptures lead by the Geomatics Laboratory of the Department of Civil, Energetic, Environmental and Material Engineering (DICEAM) of the Mediterranean University of Reggio Calabria. 3D modeling is based on the use of imaging techniques such as digital photogrammetry and computer vision. The achieved results demonstrate the effectiveness of the technique used in the cultural heritage field for the creation of a digital production and replication through 3D printing. Moreover, when considering renewed interest in the context of international museological studies, augmented reality (AR) innovation represents a new method for amplifying visitor numbers into museums despite concerns over returns on investment. Thus, in order to further valorize and disseminate archaeological heritage, we are developing an app for tourism purposes. The created app allows the user, in real time, to obtain additional information on the object of investigation, even allowing them to view the 3D model in AR.

In this paper, we present the software architecture of a complete mobile tourist guide for cultural heritage sites located in the old town of Chania, Crete, Greece. This includes gamified components that motivate the user to traverse the suggested interest points, as well as technically challenging outdoors augmented reality (AR) visualization features. The main focus of the AR feature is to superimpose 3D models of historical buildings in their past state onto the real world, while users walk around the Venetian part of Chania’s city, exploring historical information in the form of text and images. We examined and tested registration and tracking mechanisms based on commercial AR frameworks in the challenging outdoor, sunny environment of a Mediterranean town, addressing relevant technical challenges. Upon visiting one of three significant monuments, a 3D model displaying the monument in its past state is visualized onto the mobile phone’s screen at the exact location of the real-world monument, while the user is exploring the area. A location-based experience was designed and integrated into the application, enveloping the 3D model with real-world information at the same time. The users are urged to explore interest areas and unlock historical information, while earning points following a gamified experience. By combining AR technologies with location-aware and gamified elements, we aim to promote the technologically enhanced public appreciation of cultural heritage sites and showcase the cultural depth of the city of Chania.

Abstract. The creation of three-dimensional models for the cataloguing and documentation of cultural heritage is today an emerging need in the cultural sphere and, above all, for museums. The cultural heritage is still catalogued and documented based on descriptive files assorted of photographic images which, however, fail to outline its spatial richness, possible only through the use of 3D artefacts. The essay aims to propose a methodology of digitalization by low-cost and easy-to-use systems, to be employed even by non-expert survey and photogrammetry’s operators. The case study of the statue of San Nicola da Tolentino, preserved at the Sant’Agostino complex in Bergamo, offered the possibility of a comparison between 3D models acquired with different digitalization tools (professional/action/amateur cameras and smartphone) and processed by several image-based 3D Reconstruction software and methods.

The study provides a methodology for 3D model processing of historic mining landscape, and its features as mining digital cultural heritage with the possibility of using new visualization means in mining tourism. Historic mining landscapes around the towns of Gelnica (eastern Slovakia) had been chosen for the case study. The underground mining spaces around Gelnica, which are currently inaccessible to clients of mining tourism, were processed using 3D modeling. Historically, correctly processed 3D models of mining spaces enable customers of mining tourism to virtually travel not only in space, but what is most important, in time as well. The up-to-date computer-generated virtual mining heritage in the form of 3D models can be viewed via the Internet from different perspectives and angles. The models created this way are currently the latest trend in developing mining tourism.

Digital Photogrammetry

The aim of this work is to present a new practical approach to digital photogrammetry to obtain 3D models of polychromatic sculptures under ultraviolet fluorescence and near-infrared by starting from photographic images. This digital photogrammetry was applied recently to a 17th-century reliquary bust representing St. Rodonio, a saint particularly venerated by the Orthodox Church, presently under restoration in the Laboratories of University of Tuscia and belonging to the Museum of Colle del Duomo of Viterbo (Italy). The acquisitions of ultraviolet fluorescence and infrared frames were performed using a Nikon D5300 digital SLR camera and a modified low-cost digital camera (Samsung Model NX3300), respectively. The three-dimensional UV and IR models were obtained using Agisoft PhotoScan® software. The generated ultraviolet 3D model of the bust makes visible, in a single file, the fluorescence induced by UV radiation on the entire sculpture, highlighting surface abrasions, organic dyes, and ancient protective features. The infrared 3D model allowed for better definition of the details of the drawing used for eyes, nose and mouth definition. In conclusion, the ultraviolet fluorescence and IR 3D models of Saint Rodonio were particularly useful as documentation tools for the conservation status and for the painting construction, allowing us to perfectly map the original and restoration materials and to detect the drawing in single dynamic 3D files following a totally non-invasive, cost-effective, and rapid approach.

Difficult Challenge

Abstract. 3D documentation and visualization of cultural heritage has a great significance in preserving the memories and history, and supports cultural tourism. It is of great importance to study the 3D reconstruction of cultural relics and historic sites. Preservation, visualization of valuable cultural heritage has always been a difficult challenge. With the developments of photogrammetry, terrestrial laser scanning, 3D models were able to obtained quickly and accurately. In this paper we present the survey and 3D modelling of an ancient temple, Banteay Srei, situated in Angkor, which has long been admired as a “Precious Gem” of Khmer Art for its miniature size of structures and exceptional refinement of the sculptures. The survey was performed with FARO Focus3D 330 and FARO Focus3D 120 terrestrial laser scanners, a micro unmanned aerial vehicle (UAV) (DJI Phantom 4 Pro) and a digital camera (Nikon D90). Once the acquired scans were properly merged, a 3D model was generated from the global point cloud, and plans, sections and elevations were extracted from it for restoration purposes. A short multimedia video was also created for the “Digital Banteay Srei”. In the paper we will discuss all the steps and challenges addressed to provide the 3D model of Banteay Srei Temple.
