The invention discloses an anti-dazzling self-adaptive high beam automobile headlamp control method and system.The headlamp is covered with a glass cover, the glass cover is made of electrochromic glass, and the glass cover is divided into a plurality of regions.The method comprises the steps that an image in front of a vehicle in the running process of the vehicle is obtained in real time; identifying an opposite vehicle and a pedestrian in the image in front of the vehicle by using an image identification technology, and calculating to obtain distance information from the vehicle to the opposite vehicle and the pedestrian and height information of the opposite vehicle and the pedestrian; the method comprises the following steps: calculating angle information of covering opposite vehicles and pedestrians by high beam illumination emitted by a headlamp, determining a corresponding area on a glass cover according to the angle information, adaptively changing voltage or current of the area, adjusting the color of the area on the glass cover so as to adjust light transmission, and further controlling the high beam illumination intensity corresponding to the area to be reduced. According to the positions and sizes of vehicles and pedestrians in the opposite direction, the high beam illumination intensity of the headlamp is adjusted and controlled in a self-adaptive mode, and safe driving is guaranteed.
本发明公开了一种防眩目的自适应远光汽车前照灯控制方法及系统,前照灯上罩有玻璃罩,玻璃罩采用电致变色玻璃制备,且玻璃罩被划分为多个区域,该方法包括:实时获取车辆行驶过程中的车辆前方图像;利用图像识别技术识别车辆前方图像中的对向车辆和行人,并计算获取车辆距离对向车辆和行人的距离信息以及对向车辆和行人的高度信息;计算前照灯发出的远光光照覆盖对向车辆和行人的角度信息,根据角度信息确定玻璃罩上对应的区域,自适应改变所述区域的电压或电流,调整玻璃罩上所述区域的颜色以调整透光性,进而控制所述区域对应的远光光照强度降低。本发明根据对向车辆及行人的位置及大小,实现自适应调控前照灯的远光光照强度,保障安全驾驶。
