The invention discloses an emergency braking method and system based on a binocular stereo camera and an intelligent terminal, and the method comprises the steps: obtaining the information of an obstacle meeting a preset condition in an image collected by the binocular camera, and calculating the three-dimensional coordinate information corresponding to the obstacle; estimating a self-vehicle driving route; and outputting a corresponding braking instruction according to the relative position relationship between the central position of the obstacle and the driving route of the vehicle, so that the vehicle alarms and/or brakes according to the braking instruction. Braking instructions matched with the obstacles can be output according to different conditions, accurate collection of the obstacles is achieved, coping strategies are output in time, an alarm is given to a driver before the collision danger possibly occurs, and the emergency braking function is automatically triggered. The method helps a driver prevent traffic accidents such as collision and rear-end collision caused by various conditions such as fatigue driving, distraction and novice on the road, and improves the driving experience. The technical problem that in the prior art, the accuracy of obstacle collection is low, and consequently emergency braking timeliness is poor is solved.
本发明公开了一种基于双目立体相机的紧急制动方法、系统和智能终端,通过获取双目相机所采集图像中符合预设条件的障碍物信息,并计算该障碍物对应的三维坐标信息;预估自车行驶路线;根据障碍物中心位置与自车行驶路线的相对位置关系,输出相应的制动指令,以便车辆按所述制动指令实施报警和/或制动。其能够根据不同情况输出与之相匹配的制动指令,实现障碍物的准确采集,并及时输出应对策略,在可能发生碰撞危险前向驾驶员发出报警提醒,自动触发紧急制动功能,帮助驾驶者预防因疲劳驾驶、分神、新手上路等各种状况引发的碰撞、追尾等交通事故,提升驾驶体验。解决了现有技术中障碍物采集准确度较低,导致紧急制动及时性较差的技术问题。
