Embodiment Construction

[0020] The overall technical solution of the patent of the present invention is: first, each monitoring point collects pictures of passing vehicles and identifies the corresponding license plate information, compares the license plate information with the same license plate information at other monitoring points, and uses the "time difference" method to determine the license plate Whether there is a suspicion of decking. The "time difference" judgment method is specifically described as: the time when the license plate appears at monitoring point A is T1, and the time when it appears at monitoring point B is T2. If the absolute difference between time T1 and T2 is less than the preset time from point A to B The shortest time point, then the car is suspected of decking.

[0021] The present invention is mainly realized by four major functional modules, i.e. vehicle detection and license plate recognition module, data comparison module, deck car judgment module, information proc...

Abstract

The invention relates to a fake-licensed car detection method based on number-plate identification and gridding supervision. On the basis of number-plate identification and gridding supervision, the method links the number-plate with the information of each supervision point, and finds out suspect fake-licensed cars by detection by time difference judgment. On the basis of video, each supervision point uses the measures of winding triggering, video detection, and the like to detect the cars passing through the point, and to identify and link the number-plates with the identical number-plate data of other supervision points, thereby finding out the suspect fake-licensed cars by detection. The method provides good measures for detecting the fake-licensed cars in the range of supervision, and the problem of fake-licensed car of identical type, which can not be solved by the current technology, can be solved.

Description

technical field [0001] The invention belongs to image processing, pattern recognition and data processing technology, specifically, after using the image processing technology to identify the vehicle license plate, the computer system performs data processing to realize the detection method of the license plate vehicle, especially the same type of license plate vehicle . Background technique [0002] At present, the existing detection methods for license plate vehicles need the support of vehicle model information, and there is no effective detection method for license plate vehicles of the same model. There are also many units in China who are researching the detection technology of license plates, and their research is basically limited to a passive solution, that is, by replacing the license plate and implanting an electronic information card in the vehicle, etc., this type of solution requires the cooperation of the vehicle. implementation and will not be discussed here...
