Résumé :

In the framework of the Belgian BELSPO AGORA 3D and DIGIT03 programs, we have evaluated 3D digitising technologies with regards to the quality of the acquisition, the capacities and limitations of each technique and also the direct cost of the different 3D digitisation processes. It is on this latest topic that the paper is focused. In order to evaluate the cost of 3D digitisation, we considered the time for the digitisation, cost of the equipment and cost of the staff. Our preliminary results show that the real cost by specimen depends on the amount of specimens to digitise. Techniques that appear to be low-cost can be the most expensive in the framework of massive digitization programs, whilst more expensive equipment can be more efficient in the long term. Therefore low-cost equipment is mainly recommended for occasional digitisation or small series of digitisations.

Résumé :

Abstract. This paper focuses on the exceptional results of the EU Study (Commission et al., 2022) to map the parameters, formats, standards, benchmarks and methodologies relating to the 3D digitisation of tangible cultural heritage (CH). The overall objective of our paper is to further the quality of the 3D digitisation process by enabling cultural heritage professionals, institutions, content developers, stakeholders and academics to define and produce high-quality digitisation standards and sustainable conservation models for the preservation, documentation, understanding, and accessibility of tangible cultural heritage assets. The aim is to achieve high quality results during the 2D and 3D recording process of CH tangible assets. This work identifies for the first time in this domain, key parameters of the digitisation process, estimated the relative complexity and how it is linked to technology, its impact on quality and its various factors. It also presents standards and formats used for 3D digitisation, including data types, data formats and metadata schemas for 3D structures within a holistic documentation approach. Finally, this work presents and describes all the features and parameters of the complexity and quality that influence the methodology and infrastructure to be used for high quality results regarding digital cultural heritage. These complexity and quality factors are illustrated in the form of radial charts with the corresponding relevant information at the end of the paper.

Résumé :

<p><strong>Abstract.</strong> The 3D digitisation of precious or delicate cultural heritage artefacts via photogrammetry is highly important for historical preservation purposes. Doing so can help mitigate against events such as natural disasters, war, and tourism damage, whilst enabling access to 3D data for researchers around the globe. While the digitisation of such artefacts offer many significant societal and academic benefits, the process in which data is captured is resource intensive and often results in inaccurate outcomes. This paper presents a novel small object scanner which automates the photogrammetry image acquisition process for the highly detailed and efficient 3D digitisation of cultural heritage artefacts across large museum collections.</p>

Résumé :

One of the challenges that museums often face is how to present their ‚treasures‘ in a form that is both comprehensive and relevant to today‘s audiences. Digital content alone is not enough in this context and 3D content is increasingly gaining importance. One of the most accessible and at the same time most effective 3D digitisation methods is photogrammetry. The result, if procedures are followed correctly, is not only high-quality content with a wide range of uses, but also potential stepping stones for effective business models. This can reduce acquisition costs quite significantly and make 3D digitisation accessible to a wider range of institutions.

Résumé :

Abstract. The present work is aimed at showing the results obtained by testing different operational solutions for single-camera photogrammetric acquisitions of numerous complex metal liturgical artefact preserved in the Church of Santa Maria di Costantinopoli in Naples (Italy). The digitisation activity is aimed at supporting documentation, restoration, valorisation and dissemination of a rich liturgical collection that is not accessible to the public for security reasons. The number and diversity of the pieces required an expeditious surveying activity conducted in situ with low-cost instrumentation and image-based techniques adopted and compared with reference to the geometric-formal complexity and state of conservation of the objects. According to the level of difficulty acquisition, this work shows the results of the digitalisation of three different types identified among the many different liturgical objects of the collection about their different geometric, compositional and technological configuration in terms of topology, shape, composition, materials and manufacturing technique. The adopted workflow produced results that allow qualitatively assess the examined objects and their materials, supporting architects, experts in the restoration of metal artefacts and art historians: the produced digital documentation represents a 3D digital support for restoration activities and, above all, to plane activities aimed at conservation and preventive maintenance, as well as for valorisation and dissemination activities through digital information systems.

Résumé :

The fragmentary nature of pottery is considered a common place. Conservators are requested to apply a proper restoration solution by taking under consideration a wide range of morphological features and physicochemical properties that derive from the artefact itself. In this work, the authors discuss on a low-cost pottery-oriented restoration pipeline that is based on the exploitation of technologies such as 3D digitisation, data analysis, processing and printing. The pipeline uses low-cost commercial and open source software tools and on the authors' previously published 3D pose normalisation algorithm that was initially designed for 3D vessel shape matching. The authors objectively evaluate the pipeline by applying it on two ancient Greek vessels of the Hellenistic period. The authors describe in detail the involved procedures such as the photogrammetric 3D digitisation, the 3D data analysis and processing, the 3D printing procedures and the synthetic shreds post processing. They quantify the pipeline's applicability and efficiency in terms of cost, knowledge overhead and other aspects related to restoration tasks.

Résumé :

Digitisation of cultural content represents one of most challenging problems of contemporary IP law. Cultural artefacts, let it be books, paintings or 3D objects, are often very old, so there are no issues in copyright protection of their content. However, the public availability of such content is in these cases strongly limited namely due to physical conditions of the carriers and subsequent conservation demands.Digitisation might serve here as powerful enabler of re-use of these works that are frequently of enormous cultural value. On the other hand, getting useful (and re-usable) digital images of 2D or 3D cultural objects means to invest into advanced technologies that are able to capture the respective content while protecting its fragile carriers from physical damage or destruction. Consequently, there is a need for business models that can motivate investors by offering them valuable consideration for such efforts.Recently, such business models are based namely on exclusive agreements between digitisers and cultural institutions that, together with specific copyright protection of digitised images in some jurisdictions, create new form of legal barriers to re-use of even very old cultural content. The paper critically discusses these new restrictive legal instruments namely in the light of the revised PSI re-use directive.

Résumé :

The utilisation of 3D digitisation and visualisation has grown considerably since 2008 and is becoming an increasingly useful tool for the digital documentation and metric analysis of archaeological artefacts and skeletal remains. It provides public access to rare and fragile specimens of palaeontological and palaeopathological importance whilst reducing the physical impact on these remains. Research in engineering and computer vision provides some insight into the impact of surface properties such as colour, specularity, reflectance and shape on the quality of the recorded 3D image, but within the archaeological and palaeontological disciplines comparable work has not yet been developed. If archaeology and anthropology are to provide long term reliable data from archaeological and palaeontological specimens in a way that doesn’t require repeated re-digitisation, we need to understand the impacts that the taphonomic histories of such samples have on our ability to 3D record them. Understanding the relationship of these taphonomic histories and the surface and optical properties will promote informed choices about the suitability of recording techniques. This thesis considers the taphonomic processes that affect the preservation of bone over archaeological, forensic and palaeontological timescales and the effect this has on the quality of 3D digital models. The digital refit of fragmentary bone samples is considered in relation to the effect of taphonomic alterations to bone. Conclusions regarding the key taphonomic factors and 3D digital model quality are drawn and areas of further work are identified.

Résumé :

A partir des usages de la numérisation 3D en archéologie, le projet de thèse Archaeoroom interroge les pratiques actuelles tant pour la recherche que pour la conservation des vestiges. Les outils déployés sur le terrain possèdent une certaine utilité en fonction des projets. Toutefois ils ne répondent pas pleinement aux besoins de précision et de résolution pour la lecture fine du relief et de la couleur dans des contextes particuliers. Le corpus se veut donc le plus large possible afin de couvrir un maximum de faciès, de matériaux, de périodes et de méthodes de travail. Il comprend des grottes ornées (Chauvet, Pech-Merle, Mas d'Azil, Marsoulas, Bédeilhac, Foissac) pour lesquelles la création de supports pour toutes les disciplines est cruciale notamment pour l'étude de l'art pariétal, des mégalithes afin de produire des relevés 3D standardisés sur un large territoire (statues-menhirs rouergates, stèles du pays Gédéo en Ethiopie, dolmen de Gréalou dans le Lot) et du mobilier archéologique issu de plusieurs musées pour confronter les outils à la notion de vérité terrain sur des objets complexes (Musée d'archéologie nationale à Saint-Germain-en-Laye, Musée Saint-Raymond à Toulouse, Centre de Préhistoire du Pech Merle à Cabrerets, Musée et sites archéologiques de Saint-Romain-en-Gal). La thèse propose l’utilisation d’une méthode confidentielle dans les sciences du patrimoine issue du domaine de la vision par ordinateur. Ce projet interdisciplinaire entre archéologie et informatique, s’applique à déterminer l’utilité de la stéréophotométrie ainsi que sa complémentarité avec les pratiques afin d'en faciliter son appropriation par les acteurs. Cette recherche s’appuie sur le développement du logiciel open-source AliceVision Meshroom avec le souhait qu’il intègre pleinement la boîte à outil des archéologues. De plus, avec la révolution en cours des méthodes par réseau de neurones, la stéréophotométrie multi-vues a désormais la capacité de modifier le processus de numérisation 3D du patrimoine en devenant un outil de reconstruction 3D à part entière
Based on the uses of 3D digitisation in archaeology, the Archaeoroom thesis project examines current practices for both research and the conservation of remains. The tools deployed in the field have a certain usefulness depending on the project. However, they do not fully meet the need for precision and resolution for the accurate reading of relief and colour in specific contexts. The corpus is therefore intended to be as broad as possible, to cover as many facies, materials, periods and working methods as possible. It includes decorated caves (Chauvet, Pech-Merle, Mas d'Azil, Marsoulas, Bédeilhac, Foissac) for which the creation of supports for all disciplines is crucial, particularly for the study of cave art, megaliths in order to produce standardised 3D readings over a wide area (statue-menhirs from Rouerga, stelae from the Gédéo country in Ethiopia, dolmen at Gréalou in the Lot department) and archaeological objects from several museums in order to test the tools against the notion of ground truth for complex objects (Musée d'archéologie nationale at Saint-Germain-en-Laye, Musée Saint-Raymond in Toulouse, Centre de Préhistoire du Pech Merle at Cabrerets, Musée et sites archéologiques de Saint-Romain-en-Gal). The thesis proposes the use of a confidential method in the heritage sciences stemming from the field of computer vision. This interdisciplinary project between archaeology and computer science aims to determine the usefulness of stereophotometry and its complementarity with current practices, in order to facilitate its appropriation by those involved. This research is based on the development of the open-source software AliceVision Meshroom, which we hope will become an integral part of the archaeologists' toolbox. In addition, with the ongoing revolution in neural network methods, multi-view stereophotometry now has the capacity to modify the process of 3D digitisation of heritage by becoming a fully-fledged 3D reconstruction tool

This project constructed virtual plant leaf surfaces from digitised data sets for use in droplet spray models. Digitisation techniques for obtaining data sets for cotton, chenopodium and wheat leaves are discussed and novel algorithms for the reconstruction of the leaves from these three plant species are developed. The reconstructed leaf surfaces are included into agricultural droplet spray models to investigate the effect of the nozzle and spray formulation combination on the proportion of spray retained by the plant. A numerical study of the post-impaction motion of large droplets that have formed on the leaf surface is also considered.

Résumé :

AbstractThe digitisation of cultural heritage, particularly within national collections such as those of Heritage Malta, presents a blend of opportunities and challenges. The establishment of the Digitisation Unit has been pivotal in adopting 3D digitisation technology, which enhances the preservation and accessibility of the National Collection. However, the lack of common international standardised methodologies and procedures has led to inconsistencies in the quality and interoperability of 3D models.This paper explores the critical differences between 2D and 3D digitisation, highlighting the advanced equipment and methodological complexities involved in 3D processes. It discusses the experiences faced during the digitisation of the National Collection, with a focus on item prioritisation and the need for robust strategies and standards. The importance of metadata and paradata, along with equipment and methodological challenges, are examined to illustrate the multifaceted nature of 3D digitisation. Despite these challenges, strategic actions such as developing internal guidelines, investing in storage solutions, and participating in initiatives like TwinIt! are identified as crucial for overcoming current barriers. The paper concludes that while the field of 3D digitisation is still evolving, the concerted efforts of institutions like Heritage Malta, coupled with ongoing innovations and standardisation efforts, hold promise for preserving and sharing cultural heritage with future generations, ensuring its accessibility and integrity in the digital age.

AbstractRecent development of built heritage digitisation has not included required interest on scientific control tool. Without such information, such efforts can be useless for later reuse of digital models. Paradata were developed with this purpose but discussion about its content remained limited. This paper aims to provide a first specific set for digital three-dimensional models of built heritage based on other experiences and previous fieldwork. It includes works developed with photogrammetry, 3D scanning and at a lesser extent manual CAD reconstruction. Thanks to these series of paradata it would be possible not only to document the scientific process behind the digitisation of heritage, but also to provide data for further research.

Résumé :

AbstractThe current effort in 3D digitisation of heritage items poses new challenges in accommodating more and higher quality information to be associated with the 3D models that are of interest to users and stakeholders. The Europeana Data Model (EDM) is a metadata schema that distinguishes between the information related to the cultural heritage object as such (represented by the class edm:ProvidedCHO) and the information related to its digital representation (edm:WebResource), brought together in the class ore:Aggregation. Work done in the context of the new common European data space for cultural heritage collected inputs from various experts and initiatives working on 3D data, metadata and paradata, in the light of studying requirements for the extension and adaptation of EDM classes to the more complex scenario of representing and sharing 3D digitised cultural heritage collections.

Résumé :

AbstractThe 3D find documentation has been an essential part of the Archaeological Heritage Office of Saxony since 2005. The great effectiveness, the considerable gains in accuracy and the consistently high quality of the data have established the 3D laboratory as a centre of expertise. Using the three close-range scanners, over 24,000 objects had been scanned and documented by mid-2020. Various projects, such as the excavation of the Neolithic well at Altscherbitz, the DFG project ‘Automated Classification’ and the international, EU-funded projects on medieval mining in the Erzgebirge, clearly show the advantages of the high-resolution digitisation of archaeological finds. In addition to standard applications, industrial methods are being used to address research questions in archaeology and conservation. For example, dimensional changes during the conservation of waterlogged wooden finds are monitored by multiple scans and wear-and-tear traces are detected and examined. Furthermore, the 3D data are employed in the important area of knowledge transfer in exhibitions and public relations. With the help of common rendered graphics, animations, 3D printing and VR/AR applications, the research results and knowledge thus acquired are presented. With the publication of the Internet portal Archaeo | 3D, a platform has been created to present the 3D data from the last 15 years to both professionals and interested members of the public.

Résumé :

Abstract3D visualisation—be it computer graphic (re)construction or digitisation—has a long tradition in archaeology and cultural heritage; original research approaches, new methodologies, and theoretical frameworks have been developed; scholarly outputs in a range of forms have been published; teaching programmes have been designed; and an array of apparatuses, including organisations, consortia, projects, conferences, journals, and book series exclusively focusing on 3D, have been established. Despite all these, 3D scholarship is still faced with scepticism and hesitation, both due to constant changes in technology and the fragile ecosystem within which it is being developed, but also due to the technological authority, lack of standards, and its non-conventional nature that does not adhere to established academic norms. The development of charters and principles, such as the London and Seville Charters, which were developed to provide guidelines that tackle these issues, have been inconsistently addressed and rarely implemented. By looking back at the origins of paradata in heritage visualisation and the ways that three-dimensionality is perceived, captured, and interpreted in conventional archaeological practice, this chapter explores the variable and dialectic processes that take place at the trowel’s edge and the often neglected perceptual, physiological, and technical factors that influence knowledge production in the process of 3D (re)construction. The chapter argues that 3D scholarship requires a leap of faith and a rethinking of the ‘how, when, and why’ of paradata on a par with our better understanding of the complexity of and recent changes in digital scholarship.

Résumé :

The present chapter investigates the emerging paradigm of cultural heritage experience, as shaped by the continuous advances in information technologies. Recent years have seen the growing digitisation of cultural heritage, leveraged by innovative information technologies (imaging technologies, multimedia, virtual reality etc.). Advanced digitisation, and digital preservation and accessibility have been instrumental in transforming conservation and scientific research methods in the field of cultural heritage, as well as people’s experience of cultural heritage assets, relics, and monuments. Digitisation and immersion technologies are already in use in the context of cultural tourism in museums and on location. At the same time, a manifold of new applications and services can be generated from the adoption and adaptation of relevant technologies already applied in other sectors (e.g. 2D/3D digital scanning technologies applied in the construction industry). The present chapter will provide a thorough review of relevant digital technologies and existing work in the field, highlighting important research efforts and achievements; and will discuss the current challenges and promising avenues for future work. Following a literature review methodology, our research will provide a critical appraisal of carefully selected work from recent scientific literature and contribute to the systematisation of the current knowledge in the field towards the identification of key challenges and the extraction of new insights in terms of potential for practical applications and future research directions in the area.

Résumé :

The three-dimensional digitisation of fortifications may be treated as a specific scenario, that is, fortifications have certain formal, dimensional and typological characteristics, as well as their setting in the territory, which make them worthy of specific study of their digitisation process. This leads us to establish standards and workflows to guarantee the most appropriate application of the chosen methods.This paper aims to analyse the peculiarities of data collection in fortifications, with an emphasis on both big castles and those located on complex orography. At the same time, this paper outlines a process for determining the digitisation resolution standard based on the required scale in order to satisfy the aim of the graphic survey, as well as the recommendations to be considered in the data collection process to obtain it.

Résumé :

Following the action plan implementation of the Virtual Multimodal Museum (ViMM) project, which finished in March 2019, the European Commission issued a Declaration on Cooperation on Advancing Digitisation of Cultural Heritage during the Digital Day in April 2019. One year later, in April 2020, the European Commission (EC) launched a call for tenders to develop a Study on quality in 3D digitisation of tangible cultural heritage (the Study), thus responding to the increasing demand for internationally recognised standards for the holistic 3D documentation of Europe’s rich cultural heritage (CH). To address this lack of standards, the Study aims to map parameters, formats, standards, benchmarks, methodologies and guidelines, relating to 3D digitisation of tangible cultural heritage, to the different potential purposes or uses, by type of tangible cultural heritage, and by degree of complexity of tangible cultural heritage. A team of researchers at the Cyprus University of Technology (CUT) is leading a consortium of partners from industry and academia across Europe to conduct this unique Study. This work in progress paper introduces the objectives and methodology of the Study, as well as presenting some of its first results.

Résumé :

Given the importance of the conservation of cultural property and the use of the digital twin as a tool for the representation of its life cycle and enhancement, we will carry out a digitisation project approach on the Church of San Antonio Abad and its protective environment, located in the city of Valencia (Spain) and currently considered an Asset of Local Relevance. A theoretical approach is made to how the digital twin could be created, taking into account the various existing techniques, namely 3D scanning, photogrammetry, and BIM methodology, to achieve the complete digitisation of the monument. This first approach allows us to understand the evasion of this property and its challenges so that the digital twin can be realised in the future.

Résumé :

The blue domes are perhaps the architectural element that best defines Valencian architecture. These structures, present in numerous historic and religious buildings, beautify the urban landscape and represent the region’s rich cultural and artistic heritage. However, despite their importance, no clear strategic plan exists for their enhancement and conservation. Creating a specialised digital repository for the blue domes of Valencia is an urgent necessity. This repository should include a comprehensive typological classification, documenting each dome's architectural and stylistic characteristics. Advanced technologies such as 3D scanning and photogrammetry can capture and store precise details of these structures. The HBIM methodology can be beneficial, allowing for the integration of detailed data on each dome's construction, materials, and conservation status. A well-organised repository would not only facilitate better heritage management but could also be linked to cultural tourism. Valencia has great potential to attract tourists interested in architecture and history. Promoting tourist routes centred on the blue domes can increase the visibility and cultural value of these elements. Furthermore, the repository could be vital for academic and professional research. Researchers, art historians, and architects would have access to a complete and detailed database, facilitating studies and conservation projects.

Résumé :

We are presenting a Terrestrial Laser Scanner simulator - a software device which could be a valuable educational tool for geomatics and engineering students. The main goal of the VirScan3D project is to cover engineering digitisation and will be solved through the development of a virtual system that allows users to create realistic data in the absence of a real measuring device in a modelled real life environment (digital twin). The prototype implementation of the virtual laser scanner is realised within a game engine, which allows for fast and easy 3D visualisation and navigation. Real life objects can be digitised, modelled and integrated into the simulator, thus creating a digital copy of a real world environment. Within this environment, the user can freely navigate and define suitable scanning positions/stations. At each scanning station a simulated scan is performed which is adapted to the technical specifications of a real scanner. The mathematical solution is based on 3D line intersection with the virtual 3D surface including noise and colour as well as an intensity simulation. As a result, 3D point clouds for each station are generated, which will be further processed for registration and modelling using standard software packages.

Résumé :

Cultural Heritage (CH) 3D digitisation is getting increasing attention and importance. Advanced survey techniques provide as output a 3D point cloud, wholly and accurately describing even the most complex architectural geometry with a priori established accuracy. These 3D point models are generally used as the base for the realisation of 2D technical drawings and 3D advanced representations. During the last 12 years, the 3DSurveyGroup (3DSG, Politecnico di Milano) conduced an omni-comprehensive, multi-technique survey, obtaining the full point cloud of Milan Cathedral, from which were produced the 2D technical drawings and the 3D model of the Main Spire used by the Veneranda Fabbrica del Duomo di Milano (VF) to plan its periodic maintenance and inspection activities on the Cathedral. Using the survey product directly to plan VF activities would help to skip a long-lasting, uneconomical and manual process of 2D and 3D technical elaboration extraction. In order to do so, the unstructured point cloud data must be enriched with semantics, providing a hierarchical structure that can communicate with a powerful, flexible information system able to effectively manage both point clouds and 3D geometries as hybrid models. For this purpose, the point cloud was segmented using a machine-learning algorithm with multi-level multi-resolution (MLMR) approach in order to obtain a manageable, reliable and repeatable dataset. This reverse engineering process allowed to identify directly on the point cloud the main architectonic elements that are then re-organised in a logical structure inserted inside the informative system built inside the 3DExperience environment, developed by Dassault Systémes.
