[0037] Below in conjunction with specific implementation mode, this technical solution is further described:
[0038] Step 1: Use median filtering to preprocess the traffic scene images recorded by the electronic police system at road intersections to eliminate the noise contained in the images. Light compensation is then used to eliminate the effects of unstable lighting or dark weather on the image.
[0039] In the first step, median filtering is used to denoise the urban traffic scene image, and light compensation is used to preprocess the urban traffic scene image. According to different image characteristics, different filter functions are selected. In this patent, the median filter is used as the filter function to preserve the details of the image. Use formula (1) to carry out median filter processing on the image.
