3D scanning represents a broad spectrum of technologies capable of capturing 3D shape of a surface. Each of these technologies has specific advantages and drawbacks that ultimately make it suitable for a a specific purpose. One of the 3D scanning technologies is photogrammetry. This technology differs from all other since it is entirely image based and requires no specialized hardware – any properly captured set of images can be used to reconstruct a 3D shape, which makes it attractive for non-professional users. One aspect of photogrammetry that makes it very useful in art digitalization and conservation work is very high texture quality. This paper explores how ordinary mobile phone cameras can be used to create high quality 3D scans of objects of various sizes. It compares the quality output from two most widely known software for photogrammetry and offers insight into the relevance of certain imaging requirements on the quality of the results. Mesh and texture quality are evaluated, as is processing time and ease of use.
