The invention provides a light shield, a method for determining the front end boundary of the light shield and a vehicle, and belongs to the technical field of front-view camera accessory arrangement. Considering the influence area of stray light at the position of an instrument panel in a vehicle on a foresight camera, light path analysis is utilized to find out the front end boundary where light reflected by a windshield enters the influence area, and the boundary position where the stray light needs to be shielded by a light shield is determined according to the light path. Therefore, while the size of the light shield is reduced, the requirement of shielding stray light in the vehicle can be met, and the influence on shooting recognition of the front-view camera is prevented.

    本发明提供遮光罩、确定遮光罩的前端边界的方法及车辆,属于前视摄像头配件布置技术领域,通过本申请的前视摄像头遮光罩前端边界的确定方法来确定遮光罩布置时的前端边界位置,考虑车辆内仪表盘位置的杂散光对前视摄像头影响的区域,利用光路分析找到经挡风玻璃反射的光线射入存在影响区域的前端边界处,根据光路确定需要遮光罩遮挡杂散光的边界位置,从而缩减遮光罩的尺寸的同时也能满足遮挡车内杂散光的需求,防止对前视摄像头的拍摄识别产生影响。
