Night vehicle high beam turn-on state discrimination method based on double cameras

The invention discloses a night vehicle high beam turn-on state judgment method based on double cameras, which comprises the following steps: step 1, two cameras are simultaneously arranged in equipment, the two cameras are located at the same position, pictures shot by the two cameras are synthesized into one picture, one picture is a low-exposure picture, and the other picture is a high-exposure picture; 2, the low-exposure image is used for judging the turn-on state of the vehicle lamp. Meanwhile, the driving track of the vehicle is tracked, and the specific processing algorithm is as follows: 2.1, binarization processing is carried out on the image, then expansion processing is carried out on the binary image, a labeling algorithm is carried out on the expanded binary image, and each connected domain is found; through the implementation of the invention, the turn-on state of the high beam of the vehicle running at night can be correctly recognized, and the license plate number of the vehicle can be correc
