The embodiment of the invention provides an anti-collision and early-warning method based on fusion of laser ranging and image ranging, and the method comprises the steps: obtaining a first distance between a to-be-measured object and a target vehicle through a laser radar, and calculating a second distance between the to-be-measured object and the target vehicle through a camera according to a binocular vision ranging method; acquiring a third distance between the to-be-measured object and the target vehicle according to the first distance and the second distance; and under the condition that the third distance is smaller than or equal to the safe distance of the target vehicle, carrying out collision early warning on the target vehicle. According to the method provided by the embodiment of the invention, the problem of single distance measurement method in the prior art is solved, and more accurate distance measurement is realized by combining multiple distance measurement methods, so that false alarm of an early warning system is prevented.

    本申请实施例提供了一种基于激光测距和图像测距融合的防撞和预警方法,该方法,包括:通过激光雷达获取待测物体与目标车辆之间的第一距离,以及通过摄像头根据双目视觉测距方法计算得到待测物体与目标车辆之间的第二距离;根据第一距离和第二距离,获取待测物体与目标车辆之间的第三距离;在第三距离小于或者等于目标车辆的安全距离的情况下,对目标车辆进行碰撞预警。本申请实施例提供的方法,解决了现有技术中测距方法单一的问题,结合多种测距方法,实现更准确的测距,从而防止预警系统产生误报。
