“…Because tangible heritage assets are of a three-dimensional (3D) nature, their digitization should follow a 3D digital world representation (provided we do not consider the dimension of time for the moment). 3D digitization of CH [17][18][19][20] brings new possibilities for presentation, research, knowledge dissemination, conservation, and physical duplication. The domain of CH is challenging for 3D digitization methods due to the wide range of object types, sizes, materials, and complexity.…”

Open laboratories (OpenLabs) in Cultural Heritage institutions are an effective way to provide visibility into the behind-the-scenes processes and promote documentation data collected and produced by domain specialists. However, presenting these processes without proper explanation or communication with specialists may cause issues in terms of visitors’ understanding. To support OpenLabs and disseminate information, digital media and efficient data management can be utilized. The CAnTi (Conservation of Ancient Tiryns) project seeks to design and implement virtual and mixed reality applications that visualize conservation and restoration data, supporting OpenLab operations at the Acropolis of Ancient Tiryns. Semantic Web technologies will be used to model the digital content, facilitating organization and interoperability with external sources in the future. These applications will be part of the OpenLab activities on the site, enhancing visitors’ experiences and understanding of current and past conservation and restoration practices.

“…At this point it should be mentioned that saliency maps correspond to textures that highlight the regions on which people eyes focus first and reflect the degree of importance of 3D areas to the human visual system. The differential saliency maps are calculated over 3D models that have been reconstructed via Structure from Motion techniques [2] (SfM) in two different time instances and capture differences on the saliency features that usually correspond to defects. Those models have been originally deployed for generating 3D saliency maps using baseline traditional methods [4], which are later used for training deep neural networks that will facilitate the saliency extraction problem in a costefficient manner.…”

“…In recent years, a wave of new technologies has surfaced to help digitize material assets and bridge the real and the digital world, which were adapted and applied also to the field of CH. In this context, [2] surveys the currently used methods in Cultural Heritage digitization with respect to 3D digitization of tangible heritage, which is currently the most common form of such processes.…”

Climate Change has increased both the severity and the frequency of a number of different types of natural hazards. Its impact on Cultural Heritage sites and monuments can be quite significant, thus mandating adequate adaptation and mitigation strategies. Cyber-Physical Systems can help towards this direction by utilizing Cultural Heritage Digital Twins, coupled with AI/ML algorithms facilitating defect/degradation detection and triggering appropriate actions.

“…3D digitization applications in the field of cultural heritage are directly linked to research and study, with the main objective of producing diverse material that can be used for documentation, restoration, and valorisation purposes (Pavlidis and Koutsoudis, 2022). In the 2019 Declaration of Cooperation on advancing the digitisation of cultural heritage, 27 European countries have called also on the European Commission's Expert Group on Digital Cultural Heritage and Europeana (DCHE Expert Group) to contribute to the development of common guidelines for comprehensive, holistic documentation of European 3D cultural heritage assets.…”

Abstract. 3D digitisation is essential to enhance knowledge and conservation processes for Cultural Heritage (CH). However, movable heritage collected in museums, e.g., archeological finds, statues, coins, and musical instruments, often consists of highly reflective surfaces and/or featureless textures. The aim of this work is to stress the Structure from Motion Dense MultiView Reconstruction (SfM-DMVR) of objects, whose optical properties are challenging to this image-based technique. To improve the results obtained by SfM-DMVR standard acquisition workflow, this study exploited the potential of combining Noise Function Pattern (NFP) projection and light Cross Polarization (CP). Moreover, High Dynamic Range (HDR) image reconstruction was tested on images acquired according to different CP angles. The SfM-DMVR of a texture-less shiny ceramic object was then compared to the one obtained by a structured light triangulation scanner, the most reliable tool for such surfaces, but unfortunately quite expensive. The advantages and limitations of the presented method are discussed.
