A method and camera-based system for determining an end position of a trailer that extends rearward from a traction unit of a vehicle and is rotatable by processing camera images captured in succession times, the method performed by the camera-based system comprises the steps of: capturing camera images continuously in time by an image sensor of at least one image capturing device of the camera-based system; determining a plurality of feature points in each camera image according to the at least one image parameter, wherein one feature point corresponds to at least one pixel in the camera image; selecting a relevant feature point from the plurality of feature points as a path element in a preferred direction defined by the density and position of the feature points according to a temporally successive position displacement (dx, dy) between the plurality of feature points in the one camera image and the corresponding plurality of feature points in the one camera image; generating at least one path describing the trailer along the preferred direction according to the path elements; and determining the position on the path as the tail end of the trailer.

    一种方法和基于摄像头的系统,用于通过处理连续时间捕获的摄像头图像,确定从车辆的牵引单元向后延伸并可转动的拖车的末端位置,基于摄像头的系统执行的方法包括以下步骤:通过基于摄像头的系统的至少一个图像捕捉装置的图像传感器连续时间捕捉摄像头图像;根据至少一个图像参数确定每个摄像头图像中的多个特征点,一个特征点与摄像头图像中的至少一个像素相对应;根据一个摄像头图像中的多个特征点与一个摄像头图像中的相应多个特征点之间在时间上相继的位置位移(dx,dy),从多个特征点中沿着由特征点的密度和位置定义的优选方向选择相关特征点作为路径元素;根据路径元素沿优选方向生成至少一条描述拖车的路径;将路径上的位置确定为拖车末端。
