Abstract
With the increasing ubiquity of digital media engagement it is worth considering how heritage artefact digitisation can evolve and adapt. Twenty-first century computing developments bring low-cost three-dimensional (3D) imaging into reach, creating opportunities for cultural materials conservators to implement efficient and comprehensive new avenues in non-contact documentation and engagement. This research presents a workflow for combining efficient photometric stereo capture workflows with structure-from-motion photogrammetry for comprehensive modelling of high- and low-frequency artefact geometry and surface texture. Presenting a range of potential applications in conservation, the excellent topographic mapping of planar surfaces brings granular accuracy and unparalleled detail to condition documentation and digital reproduction of flat objects with finely textured surfaces, such as paintings or printing plates.
