Embodiment Construction

[0018] The invention proposes a method for detecting the behavior of automatic flopping. This method can effectively improve the monitoring of vehicles that use the automatic card turning device for card decking, and can form an effective deployment and control strategy based on this, and significantly improve the efficiency of public security criminal investigators and traffic police in solving cases. The following describes in detail through specific embodiments.

[0019] The method provided by the embodiment of the present invention is suitable for card flip detection on closed roads. Closed roads are characterized by fixed vehicle entrances and exits. For example, expressways are closed roads. figure 1 An example of a closed road. The closed road includes 11 bayonets from bayonet a to bayonet k; where bayonet a, bayonet i, bayonet j and bayonet k are exit bayonets or entrance bayonets for vehicles entering the closed road; Bayonet b, bayonet c, bayonet d, bayonet e, bay...

Abstract

The invention provides a method for automatically detecting an automatic plate turning device on a closed road. According to the method, whether a vehicle implements the automatic plate turning behavior or not is judged based on the records in an inspection spot meter and a license plate meter and the inspection spot information about getting in and out of inspection spots on the closed road, and a turned plate number of the vehicle is worked out according to the related inspection spot data, the track collision operation and the set operation under the situation that the vehicle implements the plate turning behavior. According to the method, supervising on the vehicle with the covered license plates through the automatic plate turning device can be effectively improved, accordingly, an effective deploy and control strategy can be formed, and the case solving efficiency of public security criminal investigation workers and traffic police is obviously enhanced.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a method and device for detecting a vehicle flip card. Background technique [0002] The automatic flipping of motor vehicle license plates refers to the automatic flipping of vehicles with two sets of license plates by using an automatic flipping device. Usually just tap the remote control in your hand, and the current license plate will be automatically flipped to another license plate. Generally, the flipping of a pair of license plates can be completed within 10 seconds. The automatic flopping of the motor vehicle number plate is a kind of illegal decking. Automatic flopping can not only avoid electronic eyes, but also impose illegal records on other car owners anytime and anywhere. The harm of automatic flop is self-evident. For example, an illegal act of evading off-site law enforcement directly leads to traffic chaos; drivers no longer worry about being punis...
