A method for determining trailer detection parameters of a trailer includes receiving, at a controller, an image from at least one camera. The at least one camera defines a field of view that includes at least a portion of the vehicle trailer. The method determines a trailer angle of the vehicle trailer relative to the tractor, identifies at least one feature in the trailer image, determines a two-dimensional distance from the at least one feature to a predetermined location on the image, and transforms the two-dimensional distance to a three-dimensional distance based at least in part on the determined angle. The three-dimensional distance is a trailer detection parameter of the trailer.
本发明提供一种用于确定拖车的拖车检测参数的方法,其包括在控制器处接收来自至少一个摄像头的图像。至少一个摄像头限定了包括车辆拖车的至少一部分的视场。该方法确定车辆拖车相对于牵引车的拖车角度,识别拖车图像中的至少一个特征,确定从该至少一个特征到图像上的预定位置的二维距离并且至少部分地基于所确定的角度将二维距离转换为三维距离。三维距离是拖车的拖车检测参数。
