The invention provides an automatic anti-dazzling high beam illumination method and system based on vehicle foresight visual perception, and the method comprises the steps: carrying out the site calibration based on a vehicle foresight visual perception system, and obtaining the inverse perspective transformation relation of a front target between a ground coordinate system and a vehicle lamp image coordinate system; obtaining a detection result of a front target and a lane line in vehicle foresight visual perception; determining whether to trigger an anti-dazzling lighting function or not according to the detection results of the front target and the lane line; if yes, a first position area of the front target in the ground coordinate system is determined, and a second position area of the front target in the vehicle lamp image coordinate system is obtained according to the inverse perspective transformation relation and serves as an anti-dazzling area; and the projection range and brightness of the high-beam vehicle lamp module are controlled and adjusted, the brightness of the lamp beads corresponding to the anti-dazzling area is adjusted, and the automatic anti-dazzling function of the high-beam vehicle lamp module can be achieved.
本发明提供了一种基于车辆前视视觉感知的自动防眩目远光照明方法及系统,其中,方法包括:基于车辆前视视觉感知系统进行场地标定,得到前方目标于地面坐标系和车灯图像坐标系之间的逆透视变换关系;获取车辆前视视觉感知中前方目标和车道线的检测结果;根据前方目标和车道线的检测结果,确定是否触发防眩目照明功能;若是,确定前方目标在地面坐标系下的第一位置区域,并根据逆透视变换关系得到前方目标于车灯图像坐标系中的第二位置区域,作为防炫目区域;控制调节远光车灯模组投射范围和亮度,包括调节防炫目区域对应灯珠的亮度,能够实现远光车灯模组的自动防眩目功能。
