Evaluation of an Impact of Different 3D Surface Scanning Protocols on Sex and Age-at-Death Assessment from Os Coxae in Bioarchaeology

Summary

This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology.

In the contemporary bioarchaeology and anthropology in general, 3D imaging technologies are being used more frequently. They offer many new possibilities, among which we can mention for instance a possibility of permanent documentation, an easier and faster sharing of data among institutions or new opportunities of data analysis. 3D surface data may be acquired with laser or structured light scanners. The present contribution investigates two important questions: (1) whether data acquired by different scanning devices are comparable and (2) whether potential differences may affect anthropological analyses, such as age-at-death and sex estimation. 3D models of pelvic bones (n=29) were acquired by laser (NextEngine) and structured light (HP 3D Structured Light Scanner PRO 2) scanners. Resulting 3D models from both scanners were subjected to age-at-death (Stoyanova et al., 2017 quantitative method) and sex (DSP 2) analyses. Furthermore, for a small sample (n=5) we created reference surfaces with RedLux Profiler device providing high-quality scans to which the outputs from both scanners were compared using surface deviation and color maps. Our preliminary results suggest that in spite of differences between the two scanners, this fact does not have a significant effect on biological profile estimation.
