Comparison of the Precision of Photogrammetry with Respect to Traditional Methods in Anthropology

Morphological observations and traditional metric methods carried out by an experienced observer can allow a precise evaluation of parameters of interest in forensic anthropology aimed at identifying remains such as chronological age and sex. However, nowadays digital image processing (3D) techniques are being increasingly used to more accurately identify skeletal remains. The objectives of this work are to carry out a 3D scan of 3 skulls, 4 coxae and 4 femurs and the calculation of the relative error of the measurements obtained by 3D photogrammetry with respect to the measurements with calipers. It is observed that the models obtained by photogrammetric techniques are the same or even better than those obtained by them from traditional anthropometric methods, although this difference is minimal in concordance studies.
