The invention relates to the technical field of image recognition, and discloses a trailer track determination method, device and equipment and a storage medium, and the method comprises the steps: extracting left and right contour images of a trailer according to an obtained side view image of the trailer when a reversing signal request is received; determining an area ratio of the contour based on the left and right contour images, and determining a hook angle of the trailer based on the area ratio of the contour; and obtaining the physical size of the whole vehicle and the current vehicle speed of the tractor, and determining the trailer track of the trailer according to the physical size of the whole vehicle, the current vehicle speed and the hooking angle. The left and right contour images of the trailer are extracted according to the side view image of the trailer, the area occupied by the left and right contours of the trailer is determined based on the left and right contour images, the hooking angle of the trailer is determined based on the area ratio of the contours, and the trailer track of the trailer is determined based on the physical size of the whole vehicle, the current vehicle speed of the tractor and the hooking angle. Compared with the prior art, the trailer track can be determined in real time, and the user experience is improved.
本发明涉及图像识别技术领域,公开了一种拖车轨迹确定方法、装置、设备及存储介质,该方法包括:在接收到倒车信号请求时,根据获取的拖车侧视图像提取拖车的左右轮廓图像;基于左右轮廓图像确定轮廓所占面积比,并基于轮廓所占面积比确定拖车的挂钩角度;获取整车物理尺寸以及牵引车的当前车速,并根据整车物理尺寸、当前车速以及挂钩角度确定拖车的拖车轨迹。由于本发明根据拖车侧视图像提取拖车的左右轮廓图像,再基于左右轮廓图像确定拖车左右轮廓的轮廓所占面积,并基于轮廓所占面积比确定拖车的挂钩角度,基于整车物理尺寸、牵引车的当前车速以及挂钩角度确定拖车的拖车轨迹,相比于现有的,本发明可实时确定拖车轨迹,提升了用户体验。
