Embodiment Construction
[0065] The present invention will be further described below in conjunction with the accompanying drawings.
[0066] Such as figure 1 Shown is a flow chart of a night vehicle detection method based on vehicle light recognition, including the following steps:
[0067] (1) Capture the nighttime traffic video through the strong light suppression camera, determine the region of interest in the image, and obtain the conversion relationship parameters between the actual spatial distance in the region of interest in the image and the pixel distance in the video;
[0068] (2) Binarize the captured video signal, perform morphological processing on the obtained binarized image, and then obtain connected area information on this basis;
[0069] (3) Establish car light screening rules to screen vehicle lights;
[0070] (4) Establish the recognition criteria for car light pairs, eliminate impossible car light pair combinations, match the car lights one by one, and establish scoring stand...
