Recently, new forms of documentation such as photogrammetry are increasingly used in forensic sciences. Photogrammetry enables an actual 3D recording of crime scenes. This technique can be used to extract 3D models of an object in digital form (coordinates and derived geometric elements, e.g. measurements, surface, area) or graphical form (sketches, maps). Photogrammetry can be applied on large and small scale, from landscape to fingerprints. The aim of this chapter is to introduce forensic experts to the principles and applications of photogrammetry for 3D recording of crime scenes, evidence, and people (living or deceased individuals). Some applications in forensic pathology, including the integration of photogrammetry with post-mortem computed tomography (PMCT), are presented.
