The digitization process for religious artifacts is subject to inherent difficulties often ignored in theoretical models or pipelines. In this paper we aim to describe these problems, which are present in practical environments such as temples and churches, using white light scanners instead of other common devices or technologies such as laser scanners and photogrammetry. Our case study is based on the digitization of two religious statues belonging to a Catholic brotherhood located in a village of the Province of Jaén (Spain), one of them presenting especially several limitations. After performing the scanning process with a portable hand-held scanner, the images captured were processed until the final models were acquired. On the basis of the results obtained, we discuss the problems arising after using well-known procedures for the reconstruction of 3D models, their causes and some possible solutions to achieving a correct digitization. It should be noted that it is not the aim of this study to establish procedures for the digitization of religious artifacts, but rather to transmit the inherent constraints of these types of scenes.

Abstract. The microphotogrammetric survey of the roman emperor Maximianus Herculeus’ medallion, described in this report, demonstrated that, despite the use of an “old” and, nowadays, “low cost” camera sensor it is still possible to obtain a detailed 3D textured model useful for different scientific purposes and virtual enhancement. Here are presented the photogrammetric results reached with the selection of the best solutions in terms of number of images, in order to speed up the entire photogrammetric workflow and pursue the goals previously explained. This medallion is one of the most important examples of roman medallions which belongs to the numismatic collection stored at the Correr Museum in Venice. Its 3D survey was developed as a parallel step of a main project which aims to acquire in three-dimensions, with a structured light scanner, the complete roman collection of medallions. This digitization project proposes to record the volumetric information of these small archaeological remains and to realize an online virtual gallery in the web site of the museum (using 3DHOP, an open source web viewer developed by the Visual Computing Lab of the CNR-ISTI of Pisa). At the end of the microphotogrammetric workflow, a distance analysis was computed to highlight the differences between the meshes obtained with a photogrammetric approach and a structured light scanner.

It is a matter of fact that 3D visualisation and proper documentation of cultural objects helps to preserve the history and memories of historic buildings, archaeological sites and cultural landscapes, and supports economic growth by stimulating cultural tourism. Preservation, visualisation and recreation of valuable historical and architectural objects and places has always been a serious challenge for specialists in the field. Today, the rapid developments in the fields of close-range photogrammetry, terrestrial laser scanning (TLS) and computer vision (CV) enable to carry out highly accurate 3D models so as to be extremely effective and intuitive for users who have stringent requirements and high expectations. In this note we present the results of the survey and 3D modeling of an ancient gate, Porta Savonarola, located within the remains of the medieval town walls surrounding the historical city center of Padua, Italy. The work has been undertaken within the framework of the project “Walls Multimedia Museum” (WMM) promoted by the local private association “Padua Walls Committee”. The goal of the project was to develop a prototype of an “extended” virtual museum, spreaded along most interesting locations of the town walls. The survey of the ancient gate was performed with a Leica C10 and P20 terrestrial laser scanners. Once the acquired scans were properly merged together, a solid model was generated from the global point cloud, and plans and elevations were extracted from it for restoration purposes. A short multimedia video was also created for the “Walls Multimedia Museum”, showing both the outer and inner part of the gate. In the paper we will discuss all the steps and challenges addressed to provide the 3D solid model of Porta Savonarola from the TLS data.

The article presents the 3D scanning methodology for large architectural objects, using stationary laser scanners in case of objects of cultural heritage. The developed methodology was tested in the field during 3D scanning of architectural monuments of the city of Samarkand in Uzbekistan. Particular attention is paid to technical and organisational problems of the 3D scanning process of architectural objects which appeared during the Second Scientific Expedition of the Lublin University of Technology to Central Asia. Next, methods for obtaining digital models adequate to the assumed archiving goals and dissemination of cultural heritage of Central Asia are presented. The described case study is, according to the authors, representative for 3D scanning of much-frequented architectural objects being monuments of great importance for cultural heritage.

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.

The Creation

<p class="VARAbstract">During the 19<sup>th</sup> and 20<sup>th</sup> centuries, numerous museums, scientific societies, and royal academies were founded in Europe and America. In this scenario, the Anthropological Museum Montané was founded in Havana, Cuba. Its collection has grown over the years, thanks to researchers, antiquarians, and amateurs. Since its foundation, the Museum Montané has become an essential institution for anthropological and archaeological research in the region. Nowadays, the Museum Montané, like other museums in developing countries, faces a challenge in the introduction of state-of-the-art technologies to digitizing exhibits and the creation of innovative projects to attract visitors. The current possibilities of virtualization of cultural heritage using digital technologies have a favorable impact on the preservation, access, and management of museum collections. The use of three-dimensional (3D) models fosters engagement with visitors, stimulates new forms of learning, and revalorizes the exhibits. In the current study, we use a hand-held structured light scanner to create 3D reality-based models of pre-Columbian crania from the Caribbean and South American collection of the Anthropological Museum Montané. The resulting 3D models were used for producing 3D printing replicas and animated videos. The 3D resources derived will encourage new knowledge through research, and provide broader access to these pre-Columbian crania collection through learning and outreach activities. The significance of digitizing these specimens goes beyond the creation of 3D models. It means protecting these fragile and valuable collections for future generations. The methodology and results reported here can be used in other museums with similar collections to digitally document, study, protect, and disseminate the archaeological heritage. Going forward, we seek to continue exploring the application of novel methods and digital techniques to the study of the pre-Columbian crania collections in Latin American and the Caribbean area.</p><p class="VARAbstractHeader">Highlights:</p><ul><li><p>A hand-held structured light scanner was used to acquire 3D reality-based models of pre-Columbian crania.

AbstractHistorical costumes are part of cultural heritage. Unlike architectural monuments, they are very fragile, which exacerbates the problems of their protection and popularisation. A big help in this can be the digitisation of their appearance, preferably using modern techniques of three-dimensional representation (3D). The article presents the results of the search for examples and methodologies of implementing 3D scanning of exhibited historical clothes as well as the attendant problems. From a review of scientific literature it turns out that so far practically no one in the world has made any methodical attempts at scanning historical clothes using structured-light 3D scanners (SLS) and developing an appropriate methodology. The vast majority of methods for creating 3D models of clothes used photogrammetry and 3D modelling software. Therefore, an innovative approach was proposed to the problem of creating 3D models of exhibited historical clothes through their digitalisation by means of a 3D scanner using structural light technology. A proposal for the methodology of this process and concrete examples of its implementation and results are presented. The problems related to the scanning of 3D historical clothes are also described, as well as a proposal how to solve them or minimise their impact. The implementation of the methodology is presented on the example of scanning elements of the Emir of Bukhara's costume (Uzbekistan) from the end of the nineteenth century, consisting of the gown, turban and shoes. Moreover, the way of using 3D models and information technologies to popularise cultural heritage in the space of digital resources is also discussed.

Purpose Digital curation addresses the technical, administrative and financial ecology required to ensure that digital information remains accessible and usable over the long term. The purpose of this paper is to trace digital curation’s disciplinary emergence and examine its position within the information sciences domain in terms of theoretical principles, using a case study of developments in the UK and the USA. Design/methodology/approach Theoretical principles regarding disciplinary development and the identity of information science as a discipline are applied to a case study of the development of digital curation in the UK and the USA to identify the maturity of digital curation and its position in the information science gamut. Findings Digital curation is identified as a mature discipline which is a sub-meta-discipline of information science. As such digital curation has reach across all disciplines and sub-disciplines of information science and has the potential to become the overarching paradigm. Practical implications These findings could influence digital curation’s development from applied discipline to profession within both its educational and professional domains. Originality/value The disciplinary development of digital curation within dominant theoretical models has not hitherto been articulated.

Landmark Localization

The psychological and social impact of the lipodystrophy syndrome on HIV-infected individuals may be quite considerable and adversely affect their quality of life. Currently no validated assessment tool for facial lipoatrophy is available. The main objective of this paper is to evaluate the reliability of interactive anthropometric landmark localization based on digitized 3D facial images. By comparing both computed tomography (CT) and structured light scanning we try to demonstrate that surface scanning shows a higher sensitivity in measuring facial reference points. Besides, we evaluate the reproducibility of facial 3D white-light scans. Three HIVpositive men attending our plastic surgery outpatient clinic for treatment of facial lipodystrophy were enrolled in the study. Localization of anthropometric landmarks measurements was performed on the patients. All patients underwent a facial CT and a facial white-light scanning on the same day. The inter-landmark distances measured on facial models developed from CT aided with VirSSPA 3D software and structured light scanning were compared to the real human models. We found that facial distances measured in the CT 3D reconstruction showed a mean error margin of 0.357 cm from the real distances measured on patients. On the contrary, mean error margin with the white-light scanning was of 0.096 cm. In both cases, measurements were found to be statistically significant (P&lt;0.05). When compared to CT reconstructions, white-light surface scanning offers a more accurate landmark localization as well as reliable reconstructions of up to less than the tenth of a millimetre as average when compared to real measurements on facial human models.
