The invention provides a license plate light adjusting method and device and electronic equipment. When the vehicle approaches the intersection, a front image is acquired. And taking the position parameter of the laser radar as a reference, taking the internal parameter, the external parameter and the first distance between the snapshot equipment and the vehicle as virtual shooting parameters, obtaining a two-dimensional point cloud image from the frame point cloud, and performing difference calculation on the two-dimensional point cloud image as a standard image of a front image to obtain a difference value between the two-dimensional point cloud image and the standard image. Determining a brightness value and a frequency value required by a license plate annular lamp of the vehicle based on the difference value; and adjusting a license plate annular lamp of the vehicle based on the brightness value and the frequency value. Therefore, the brightness of the license plate annular lamp can be automatically adjusted at the intersection, and the license plate recognition degree of the intersection snapshot device is improved. The situation that the eyes of a driver are damaged due to the fact that light is supplemented to the snapshot device through a light supplementing lamp is avoided, and driving safety is improved.
本申请提供了一种车牌灯光的调节方法、装置和电子设备。当本车接近路口时,获取前方图像。以所述激光雷达的位置参数为基准,以所述内参、所述外参和抓拍设备与本车的第一距离为虚拟拍摄参数,从所述帧点云中获得二维点云图像,作为前方图像的标准图像进行差异计算,获得两者的差异值。基于所述差异值确定本车的车牌环形灯所需的亮度值和频率值;基于所述亮度值和所述频率值调节本车的车牌环形灯。从而实现了在路口自动调节车牌环形灯的亮度,提高了路口抓拍设备对车牌的识别度。避免了通过补光灯为抓拍设备补光,导致对驾驶员眼睛的伤害,提高了驾驶安全。
