A case study of 3D technologies in higher education: Scanning the metalwork collection of museums sheffield and its implications to teaching and learning

Abstract

Abstract-This paper describes results from the fast 3D scanning project conducted at Sheffield Hallam University in collaboration with Museums Sheffield. We focus on the technological aspects that are required for fast scanning and discuss the steps in the process from scanning and noise removal to 3D post-processing and how the resulting 3D models can be made available on a standard web browser. We also discuss some implications to the teaching and learning of 3D technologies to undergraduate and postgraduate courses.

Digitalization and 3D Documentation Techniques Applied to Two Pieces of Visigothic Sculptural Heritage in Merida Through Structured Light Scanning

“…To this end, numerous examples are studied where the technique and methodology are similar to the one applied in the present study. Those that reflect a faithful comparison of their evolution stand out [44][45][46]. The purpose of geometric documentation techniques is to capture the shape, geometry in the coordinate axes (xyz) and colour characteristics (according to the RGB model) of a volume or environment, with the aim of obtaining a three-dimensional model of it with sub-millimetric precision [47].…”

“…There were problems in capturing the geometry of the pieces, since their surfaces reflect too much light. Therefore, and according to Rodrigues and Kormann [46], in order to fix this problem, a thin layer of opaque lacquer or powder was applied to the places that generate this type of issue.…”

Semantic annotation services for 3D models of cultural heritage artefacts

“…representations raise from a museum perspective. The discussion in this Chapter differs from previous related articles [21,22,110,111,152,191,207,208], because the main aim of the 3D scanning process described here is to generate a test-bed of 3D content that can be used to apply, test and evaluate a rich set of annotation services. This work focuses also on the workflow to streamline the generation of multiple 3D and 2.5 D representations of each object.…”

“…3D data acquisition tools such as laser scanners can be used by museum institutions to document their collections precisely in topology and colour, to generate high-fidelity three dimensional surrogates for preservation and archival purposes [110]. Although 3D laser scanners have been used previously to digitize museum artefacts, from small potteries to large statues [21,22,110,111,152,191,207,208], these previous research have focussed on the value of 3D representations from a curatorial perspective. They examine the advantages and potential issues that 3D…”

“…These projects fail to take advantage of community-generated tags and annotations drawn from ontologies. 3DSA also differs from other applications that only use folksonomic tags and keyword/full-text search [256,208,261] which often creates inconsistent and inaccurate search results. The 3DSA project combines user-generated tags/annotations, automatically-inferred metadata and ontologies to deliver a hybrid approach, that provides novel methods for discovering information about 3D cultural artefacts or their significant parts, features or decorations.…”
