Method for traffic intersection rule breaking detection based on vehicle license plate recognition technology

Abstract

A method for traffic intersection rule breaking detection based on the vehicle license plate recognition technology comprises the steps that rule breaking information of a vehicle passing through a traffic intersection is detected, so that an image of the vehicle generating the rule breaking information is obtained; the position of a vehicle license plate area is found in the image of the vehicle; the vehicle license plate area is segmented into single character areas; the segmented single character areas are analyzed, so that a number of the vehicle license plate is obtained; the number of the vehicle license plate is correlated to the rule breaking information of the vehicle breaking the rule. According to the method for traffic intersection rule breaking detection based on the vehicle license plate recognition technology, the image of the vehicle license plate area is preprocessed, so that influence of each disturbed image is eliminated to the maximum degree, corresponding treatment can be conducted according to the level of the rule breaking information, traffic jams caused by real-time intervention in the rule breaking information are avoided, vehicles breaking rules multiple times can be treated to the maximum degree, and even vehicles with historical traffic law breaking information are treated in time.

Description

Technical field: [0001] The invention relates to a method for detecting violations at traffic intersections, and more particularly, to a method for detecting violations at traffic intersections based on license plate recognition technology. Background technique: [0002] At present, the detection of traffic violations at intersections usually uses "electronic eyes". Realize all-weather monitoring, capture graphic and text information of vehicle violations, and perform post-processing according to the violation information. [0003] "Electronic eyes" generally take at least three images of illegal vehicles, one is an instant violation image, one is a license plate recognition image, and one is a panoramic image. Among them, the license plate recognition image is very important, which directly determines the identification of the violating vehicle. If the license plate number cannot be accurately recognized, the responsibility of the violating vehicle cannot be investigated. ...

Problems solved by technology

[0004] However, when taking images, the actual situation is often more complicated. Road signs, billboards, trees, pedestrians, buildings, etc. will interfere with the captured images, making certain areas of the acquired images difficult to identify, and therefore may make the acquired images Unable to accurately identify the license plate number
