Massive 3D Digitization of Museum Contents

Abstract

The goal of the 3D-ICONS European Project is to provide EUROPEANA ( www.europeana.eu ) with accurate 3D models of architectural and archaeological monuments and buildings of remarkable cultural importance. The purpose of this paper is to describe the specific processing pipeline that has been set for digitizing a significant part of the Civic Archaeological Museum in Milan (Italy). All the technical and logistic aspects needed for capturing 3D models in a Museum environment, the implication with IPR, and the metadata acquisition, are covered. The main issue is generating a good result by the technical point of view, minimizing the impact on the usual Museum activity during the 3D capturing operations, shortening in the meantime the processing time to the minimal allowed by the different applicable techniques. This condition has led different choices related to the survey technologies (laser scanning and image based modeling) and the related data processing. Both technical and descriptive metadata have been collected for each item acquired, for generating a record of data searchable on EUROPEANA, with the addition of new metadata not defined in the minimal record, for making traceable the path leading to the generated digital content. The paper gives a general discussion of such issues with some specific examples referred to the large set of 3D objects digitized within the 3D-ICONS project

Image-based 3D capture of cultural heritage artifacts an experimental study about 3D data quality

“…Such early comparison on small volumes was later extended by consideration of various commercial and open source image-based solutions by Remondino et al [9], evidencing the not negligible influence of the SfM and Image Matching (IM) algorithms on the final result. However, as demonstrated in digitizing an entire museum [10], the efficiency of image-based 3D digitizing of small objects is nowadays clear, but the metrological quality of the many 3D data collected in that project, although comparable or better than ToF and PS laser scanners, seems not always at the same level of high end triangulation-based range devices. Exploring this specific point is the motivation of the present paper.…”

Digital curation and online resources: digital scanning of surgical tools at the royal college of physicians and surgeons of Glasgow for an open university learning resource

“…Time and again glare has resulted in inaccurate digital model representations, and the results of this study are no different (Nicolae et al, 2014;Guidi et al, 2015). Because the surgical tools were so fragile, only non-invasive methods of glare reduction could be taken.…”

“…Previous studies have highlighted the benefits of using 3D learning tools in academic subjects, improving understanding and concentration (Guidi, Barsanti, Micoli, & Russo, 2015). Although it was not possible to generate 3D digital models in this study, the final products were interactive.…”

SMART SfM: SALINAS ARCHAEOLOGICAL MUSEUM

“…Furthermore, in this first experiment, it was necessary to choose only a part of the collection: the most easily accessible, that was that one in the outdoor atrium, in order to detect any accidents within the indoor paths. (Guidi, G. et al 2015) Then, I have programmed a number of groups depending on the number of types / objects to be photographed. In this way, the The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLII-2/W5, 2017 26th International CIPA Symposium 2017, 28 August-01 September 2017, Ottawa, Canada students were already best routed in order to achieve, each of them, from two to more datasets.…”
