Comparing The Accuracy Of Close-Range Photogrammetry To Microct Scanning Via Surface Deviation Analysis Of 3d Digital Models Of Hominin Molars, Margaret J. Furtner
LSU Master's Theses
The purpose of this study is to assess whether close-range photogrammetry is a viable alternative to microCT scanning for the construction of 3D models of isolated teeth. Photogrammetric scanning is more cost-effective and less time-consuming than CT scanning, and in paleoanthropological contexts eliminates the possibility of exposing fossils to doses of radiation that affect ESR dating. Samples of fossil (Homo naledi), archaeological, and contemporary human molars were scanned via microCT scanning and close-range photogrammetric scanning. The photogrammetric scans included 96 digital images per tooth which were used to construct a 3D triangular mesh. The resulting models of the tooth crowns …
