Forensic
application of 3D technology on biometric identification
Version
of the method of Forensic 3D reconstruction by use of phase-shift laser 3D
scanner can be applied for biometric identification of suspects in robbery
cases. The main advantage of the method is precise determination of height
of an perpetrator from surveillance camera videos. Precision of the method
is about 1 cm in a single measurement. The method involves "Z+F"
pulse laser 3D scanner and 3D Suspect Measurement software from Delft
Forensics. In real robbery cases perpetrator practically always cover
his/her face with some mask and classical biometric identification is not
possible. In such cases precise determination of height of the perpetrator
seems to be of critical importance for forensic-biometric identification and
especially in cases of exclusion of a suspect as a possible
perpetrator if measurements shows substantial difference between height of
the perpetrator recorded on surveillance camera video and height of
physically measured suspect.
