A system for determining a distance between a camera and a hitch ball of a vehicle. The system includes a camera configured to be mounted on the vehicle and an electronic processor connected to the camera. The electronic processor is configured to: determine a first location and a second location associated with a point on the trailer; determining a rotation angle between the first position and the second position; and determining a null space of the matrix using the first position, the second position, and the rotation angle. In one example, the matrix is and the null space of the matrix includes a value of the distance (dl) between the camera and the hitch ball. The electronic processor is further configured to perform autonomous or semi-autonomous vehicle operations based on the distance (dl) between the camera and the hitch ball.
一种用于确定车辆的相机和挂接球之间的距离的系统。该系统包括配置成安装在车辆上的相机和连接到相机的电子处理器。电子处理器被配置成:确定与拖车上的点相关联的第一位置和第二位置;确定第一位置和第二位置之间的旋转角度;并且使用第一位置、第二位置和旋转角度来确定矩阵的零空间。在一个示例中,矩阵为并且矩阵的零空间包括相机和挂接球之间的距离(dl)的值。电子处理器还被配置成基于相机和挂接球之间的距离(dl)来执行自主或半自主车辆操作。
