A critical assessment of the potential for Structure-from-Motion photogrammetry to produce high fidelity 3D Dental Models.

The data analysed in the article "A critical assessment of the potential for Structure-from-Motion photogrammetry to produce high fidelity 3D Dental Models" published in the American Journal of Physical Anthropology. The paper assesses the fidelity of 3D dental models of human molars generated using structure-from-motion photogrammetry by comparing them to reference models generated using a structured light scanning system (GOM ATOS core 80). Individuals were from the St. Michael's Litten, Chichester assemblage (dated AD1550-1900) held at University College London, Institute of Archaeology. This collection includes the sets of photographs used to generate 3D models in Agisoft Metashape for each individual. In addition, the composite full focus images produced using focus stacking are included which were used to perform focus stacked structure-from-motion photogrammetry. The specimen numbers correspond to the skeleton numbers of each individual. The site code for St. Michael's Litten is ESC11. Data objects are available to download of the 3D models generated. This includes the structured light scanner reference models (n=17), the structure-from-motion 3D models (n=17) and the focus stacked structure-from-motion models (n=9). All 3D models assessed, and the photographs used to generate the models, are available from the UCL research data repository. Further details of the methods used to generate the 3D models and capture the images for photogrammetry are provided in the associated paper DOI: 10.1002/ajpa.24109.
