本发明涉及一种用于车辆的高级驾驶员辅助系统(100),所述高级驾驶员辅助系统(100)用于检测在所述车辆前方道路的透视图像中的车道标记,所述透视图像定义了消失点。所述高级驾驶员辅助系统(100)包括:特征提取单元(101),用于从所述透视图像中提取多个特征(尤其是车道标记),用于生成特征坐标组(尤其是车道标记坐标),其中所述特征坐标组定义了在所述透视图像中多个特征的各自位置;处理单元(109),用于:生成多个特征坐标对,其中每个特征坐标对定义一条直线;基于所述多个特征坐标对的子集估计车道曲率,其中对于所述多个特征坐标对的所述子集的每个特征坐标对,所述特征坐标对定义的直线与所述透视图像的预定义的目标部分相交,所述预定义的目标部分包括所述消失点的多个可能位置。

    A driver assistance system detects lane markings in a perspective image of a road in front of a vehicle. The driver assistance system extracts a plurality of features, in particular lane markings, from the perspective image for generating a set of feature coordinates, in particular lane marking coordinates. The system generates a plurality of pairs of feature coordinates, each pair defining a straight line, and estimates a lane curvature on the basis of a subset of the pairs of feature coordinates. For each pair a straight line defined by the pair intersects a predefined target portion of the perspective image, the predefined target portion including a plurality of possible positions of a vanishing point.
