The invention relates to a semi-trailer tractor inner wheel difference area anti-collision early warning method based on a visual sensor, and the method comprises the steps: respectively installing an infrared camera at the left side and the right side of a tractor cab, and obtaining the environment information of the corresponding side in the turning process of a tractor; the controller can obtain the included angle beta between the tractor and the trailer in the turning process through image processing calculation. The minimum turning radius in the turning process of the semi-trailer tractor can be obtained through calculation of a preset model, an inner wheel difference area is predicted and simulated, and the inner wheel difference area is displayed to a driver in real time through a center console display screen in combination with visual information. Semantic recognition is conducted on the image information through a deep learning algorithm, and when it is recognized that the information of people, vehicles and objects is in the inner wheel difference area, the vehicle-mounted sound system sends early warning information to a driver, so that the purpose of anti-collision early warning in the inner wheel difference area in the turning process of the semi-trailer tractor is achieved.

    本发明涉及基于视觉传感器的半挂牵引车内轮差区域防碰撞预警方法,在牵引车驾驶室的左右两侧分别安装一个红外摄像头,用于获取牵引车转弯过程中相应侧的环境信息,控制器通过图像处理计算可得出转弯过程中牵引车与挂车之间的夹角β。通过预设模型计算便可得出半挂牵引车转弯过程中最小转弯半径,预测并模拟出内轮差区域,结合视觉信息通过中控台显示屏实时呈现给驾驶员。利用深度学习算法对图像信息进行语义识别,当识别到人、车、物信息在内轮差区域内,车载音响向驾驶员发出预警信息,以达到半挂牵引车转弯过程中内轮差区域防碰撞预警目的。
