Vehicle light control method and device based on camera

The invention provides a vehicle light control method and device based on a camera. The method comprises the following steps: acquiring traffic state information corresponding to a vehicle and acquiring environment state information corresponding to the vehicle based on a preset camera, and acquiring vehicle state information of the vehicle based on a controller local area network bus; and generating a corresponding light control instruction based on the traffic state information, the environment state information and the vehicle state information so as to control the vehicle to perform high and low beam switching operation. According to the vehicle light control method based on the camera, the application scene is wider, the applicability is higher, the implementation cost is low, intelligent switching of the high beam and the low beam can be comprehensively achieved, the vehicle light control efficiency and precision are effectively improved, and therefore the risk of traffic accidents at night is greatly r
