Forensic 3D Surface Digitizing plays an important role in the field of the documentation of forensically-relevant injuries, especially when a detailed 3D reconstruction is necessary.
3D surface digitizing is an optical measuring method, which is normally used for 3D documentation and measurements in prototyping and design technology, where a very high precision is required.
The process consists of two steps: firstly photogrammetry is performed. Utilizing this optical measuring process, highly accurate non-contact measurements of 3D coordinates of discrete object points are obtained. Secondly the 3D surface of bodies, tools and vehicles is acquired by 3D optical scanning.
We are using the TRITOP / ATOS II / ATOS III (GOM, Braunschweig, Germany) system which has the advantage that it can be used for the color true 3D surface documentation of small and large view areas. Using this technology, documentation ranging from fine detailed structures (skin lesions or fine instrument structures) to overview documentation (whole body or entire vehicle) is possible.
The resulting "virtual 3D-models of injured bodies" are used for comparison with "virtual 3D-models of the possible injury-causing instruments" and for the reconstruction of accidents and the course of events.
