The invention relates to a method for identifying an included angle between a tractor and a trailer compartment. Devices for implementing the method comprise a tractor main vehicle and the trailer compartment.The method comprises the following steps: arranging a camera on the tractor main vehicle to identify a reference line identifier arranged at a front end of the trailer compartment, and calculating the change of the angle of the reference line identifier in a camera image so as to obtain the included angle between the tractor main vehicle and the trailer compartment. According to the method, complex sensors such as a corner sensor do not need to be installed, installation difficulty is reduced, camera cost is low, the measurement method is simple, measurement is conducted through a computer vision image method, precision is high, and the modeling accuracy of the automatic driving truck system is improved.
本发明是一种牵引车与挂厢夹角的识别方法,包括牵引车主车和挂厢,在所述牵引车主车上设置相机来识别设置在挂厢前端的参考线标识,计算参考线标识在相机图像中角度的变化,从而得到牵引车主车和挂厢的夹角。本发明无需安装转角传感器等复杂的传感器,降低了安装难度,并且相机成本低,测量方法简单,通过计算机视觉图像的方法测量,精度较高,提高了自动驾驶卡车系统的建模准确度。
