用于车辆前照灯的照射距离调节的方法
摘要：
本发明涉及一种用于汽车(1)中的前照灯(2)的照射距离调节的方法，该方法包括以下步骤：检测第一坐标(11)，该第一坐标与车辆(1)的位置相对应；处理与车辆(1)相连的摄像机(4)的至少一个图像，用以检测第二坐标(15)，该第二坐标与车辆(1)前方区域(7)的车道(8)上的对象(9)的位置相对应；根据第一坐标(11)、第二坐标(15)和摄像机(4)相对于车道(8)的高度来计算车辆(1)的参考角(12)；并且根据参考角(12)调节前照灯(2)的照射距离。
摘要（英）：

A method for adjusting the lighting range of a headlamp in a motor vehicle, is performed with the following steps. A first coordinateis acquired that corresponds to a position of the motor vehicle. At least one image of a camera connected with the motor vehicle is evaluated so as to acquire a second coordinate that corresponds to the position of an object on a roadway in the zone ahead of the motor vehicle. A reference angle is calculated for the motor vehicle from the first coordinate, the second coordinate and a height of the camera over the roadway. The lighting range of the headlamp is adjusted based on the reference angle.
