The present application provides a method and device for detecting vehicle violations. The method includes: detecting the target vehicle in the collected image, obtaining the first relative position ratio between the license plate of the target vehicle and the target vehicle, and determining the standard value according to the first relative position ratio; In the process of tracking the target vehicle, the tracking image is collected, and the position of the tracking point of the target vehicle in the tracking image is obtained; the second relative position between the license plate of the target vehicle and the target vehicle is obtained by using the position of the tracking point of the target vehicle in the tracking image. Position ratio, to determine whether the second relative position ratio is the same as the standard value; if not, use the standard value to correct the position of the tracking point, use the corrected position of the tracking point to obtain the rear correction value of the tracking image, and according to the tracking The rear correction value of the image is used to determine whether the target vehicle violates regulations. The present application obtains the correction value of the rear of the vehicle through the position of the corrected tracking point, and then judges whether the vehicle violates the regulations according to the correction value of the rear of the vehicle, which can avoid the problem of misjudgment.
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). ...
