Method and device for detecting vehicle violation

Abstract

The invention provides a method and device for detecting vehicle violation. The method includes the steps of detecting a target vehicle in collected images, obtaining a first relative location ratio of a licence plate of the target vehicle to the target vehicle, and according to the first relative location ratio, determining a standard value; in the process of tracing the target vehicle, collecting tracing images, and obtaining the locations of the target vehicle at tracing points of the tracing images; utilizing the locations of the target vehicle at the tracing points of the tracing images to obtain a second relative location of the license plate of the target vehicle to the target vehicle, and judging whether or not the second relative location ratio is equal to the standard value; if not, utilizing the standard value to modify the locations of the tracing points, utilizing the locations of the tracing points after rectification to obtain a trail modification value of the tracing images, and according to the trail modification value of the tracing images, judging whether or not the target vehicle breaks traffic regulations. By means of the locations of the tracing points after the rectification, the trail modification value is obtained, whether or not the vehicle breaks the traffic regulations is judged according to the trail modification value, and therefore the problem ofjudgement errors can be avoided.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method and device for detecting vehicle violations. Background technique [0002] Electronic police are playing an increasingly important role in traffic management because of their ability to alleviate the problem of insufficient police force. Take the snapshot of violating rules by running a red light as an example. After a vehicle has violated the rules, the ideal image chain of violation evidence required by the traffic control department is the snapshot of the vehicle that has not crossed the stop line (such as Figure 1A The first type of evidence image shown), the snapshot of the vehicle has crossed the stop line (such as Figure 1B The second type of evidence image shown) and the snapshot of the vehicle going straight toward the opposite intersection after crossing the stop line (such as Figure 1C shown in the third category of evidence image). ...
