Digital 3D reconstructed models A proposition for structuring visualisation workflows using semantic technologies for recommendations

Abstract

It is common for cultural heritage applications to use spatial and/or spectral data for documentation, analysis and visualization. Knowledge of data requirements coming from the cultural heritage application and technical alternatives to generate the required data, based on object characteristics and other influential factors, pave the way for the optimal selection of a recording technology. It is a collaborative process, requiring the knowledge of experts both from cultural heritage domains and from technical domains. Currently, this knowledge is structured and stored in an ontology (so-called COSCH KR ). Its purpose is to support CH experts who are not familiar with technologies by prescribing an optimal spatial or spectral recording strategy adapted to the physical characteristics of the cultural heritage object and the data requirements of the targeted CH application. The creation of digital 3D reconstructed models for analysis and visualization purposes is becoming more and more common in humanities disciplines. Therefore, an implementation of the mechanisms involved in visualization applications into this ontology would have huge benefits in creating a powerful recommendation solution. Illustrating the overall structure of COSCH KR , this paper addresses and discusses challenges in structuring the processes of cultural heritage visualization and implementing these into the ontology.

Development of Expert System for the Selection of 3D Digitization Method in Tangible Cultural Heritage

“…These objects have been characterized by different dimensions, shape, color, texture, resistance to negative environmental influences and other characteristics. It is important to document activities related to protection of cultural heritage with as much information as possible [3,4]. Renju et al introduced a 3D digitizing pipeline for cultural heritage by using 3D technology for recovering geometry and texture with high precision [5,6].…”

“…Analyzing the costs related to 3D digitization in cultural heritage, Niccolucci [7] presented the figures from some case-studies and showed that owing to technological advancements, the costs of 3D data acquisition had been constantly decreasing. Selection of 3D digitization method in the field of cultural heritage represents a big challenge, especially for persons who are not experts in the field of 3D digitization (conservators, art historians, archaeologists) [4]. The aim of this paper is to develop an expert system for the selection of the most suitable 3D digitization method for scanning of different individual cultural heritage objects.…”

3D digital conservation and restoration skills for the 21st century

“…The creation of a 3D model and the subsequent steps towards restoration is, as Wefers et al (Wefers et al, 2017) states, a multidisciplinary task. The detailed requirements are set by CH experts, but the task itself is often executed by technical experts.…”
