The invention provides a method and system for calculating the appearance size of a vehicle body, and the method comprises the steps: detecting the shape of the vehicle body, detecting the size information of the vehicle body through a vehicle shape calculation system, and transmitting the size information to a vehicle appearance early warning system; detecting a lane scene, collecting image information of a lane in front of the vehicle through a lane long-distance detection system, and obtaining road obstacle position information; and calculating collision risk, allowing the vehicle appearance early warning system to compare the size information with the road obstacle information, and giving out a prompt if the collision risk exists so that the size change of the vehicle body appearance and the obstacle information on the road can be detected in the driving process, judging the vehicle collision risk by calculating the size of the vehicle body and the remaining passing space of a lane under the obstruction of an obstacle, sending warning information and providing the warning information to a driver and passengers.
本发明提供一种车身外观尺寸的计算方法及系统,检测车身形状,车身外形计算系统检测车身的尺寸信息,并将尺寸信息发送至车辆外形预警系统;检测车道场景,通过车道远距离检测系统采集汽车前方车道的图像信息,获取道路障碍物位置信息;计算碰撞风险,车辆外形预警系统将尺寸信息与道路障碍物信息的进行比较,若存在碰撞风险则发出提醒,能够在行车过程中实施检测车身外观的尺寸变化,和道路上的障碍物信息,通过计算车身尺寸和车道在障碍物的阻碍下剩余的通行空间,判断车辆发生碰撞的风险大小,并发出警报信息,提供驾驶员和乘客。
