DISTANCE ESTIMATION OF VEHICLE HEADLIGHTS

The present invention relates to a method for determining the distance to a vehicle for use in an AHC-System, comprising:capturing a raw image by using a camera of an AHC-System at nighttime; determining by the AHC-System that the raw image includes a headlight of a vehicle;extracting by the AHC-System an image segment of the raw image including the headlight of a vehicle; refining the image segment by applying a classifier, such as to generate a refined image including the a headlight of a vehicle; building a feature vector based on the refined image; and estimating the distance to the vehicle based on the feature vector. The present invention also relates to an image processing system adapted to perform the above method. 车辆前灯的距离估计。本发明涉及在AHC系统中使用的用于确定到车辆的距离的方法，该方法包括：在夜间通过使用AHC系统的摄像头拍摄原始图像；由AHC系统确定该原始图像包括车辆的前灯；由AHC系统提取原始图像中包括车辆的前灯的图像片段；通过应用分类器来精选该图像片段，以生成包括车辆的前灯的精选图像；基于该精选图像构建特征向量；以及基于该特征向量估计到该车辆的距离。本发明还涉及用于执行上述方法的图像处理系统。
