When inspecting clothing from a homicide case, it is usually necessary to measure where injuries may have occurred on the body. One means of recording the 3D positions of such clothing defects or marks on clothing involves using a 3D laser scanner. After putting the clothing on a mannequin, we use the laser to sweep through one side, creating a 3D mesh from the surface points.

3D scanning for forensics is an ever growing and useful application of laser based measurement technologies in fighting crimes and reconstructing events. Like all forensic tools, however, 3D scanning has its strengths and its limitations.


12/09/2009

As 3D scanners become more common for capturing and preserving evidence, police, forensic technicians, and others involved in the field need to be aware of the applications, benefits, and limitations of this technology and how it can be used in the analysis of evidence and crime scenes.
