The invention relates to an image forensic method for the
traffic management industry, in particularly to a method for the
image forensics of motor vehicle plate covering and
staining behaviors, wherein an
induction coil or
video detection is utilized to detect vehicles, and when a passing vehicle is detected, a
signal is sent to a control host; the control host receives the
signal, a
wireless network is utilized, and simultaneously, a plurality of high-definition cameras are enabled to
shoot; the cameras
shoot from multiple angles, the shot pictures of the cameras from the adjacent angles can clearly capture the common part of the vehicle, and condition that the pictures are a
group of pictures of the same vehicle from different angles is proved; the
road surface has an obvious mark when the vehicle is shot, the mark can be identified from the shot picture, so the
group of pictures are further proved to be taken on the same vehicle from multiple angles at the same place; through
global positioning system (GPS) timing, all the cameras are synchronized, times and places are added onto the pictures after the cameras take the pictures, so the
group of pictures are further proved to be taken on the same vehicle from multiple angles at the same place; according to steps 3 to 5, an complete chain of evidence is formed; and a plate
identification system is utilized to compare a head picture with a
tail picture of the vehicle to find out the plate covering or
staining condition.
