Abstract:
Photogrammetry is the process of making measurements and acquiring dense 3D geometric information from photographs or stereoscopic image overlaps, especially for recovering the exact positions of surface points. Three-dimensional/computer aided design (3D/CAD) photogrammetry has been shown to have extensive applications in a variety of fields, including for documentation of forensics-relevant traumatic injuries. Forensic, 3-D/CAD-supported photogrammetry creates morphologic data models of the injury and of the suspected injury-causing instrument allowing the evaluation of a match between the injury and the instrument [1, 2]. This enables comparing the virtual 3D model of the injury against the virtual 3D model of the possible injury-causing instrument. In subjects with traumatic injuries of the skin and bones, 3-D/CAD photogrammetry can help determine the shape and size of the injury as well as a true-to-scale correlation of the wound and inflicting tool.
