Method for image forensics of motor vehicle plate covering and staining behaviors

Abstract

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.

Description

technical field [0001] The invention relates to an image forensics method for the traffic control industry, in particular to an image forensics method for motor vehicle blocking and defacement of license plates. Background technique [0002] With the continuous construction of urban roads, the number of motor vehicles is also increasing, and the traffic monitoring in cities is also increasing. In order to avoid the "electronic eyes" or rush on the road, some drivers deliberately cover or deface the number plate, which brings many traffic hazards. Once a traffic accident occurs, it will be more difficult to investigate and deal with. [0003] At present, the main methods of the traffic control department for such violations are as follows: first, the traffic police patrol the road, and if they find a motor vehicle with a cover plate or defaced number, they will catch up and punish them. In this case, the motor vehicle that violates the rules may be Accelerate escape, increas...
