The invention provides an anti-collision early warning method, a vehicle-mounted device and a storage medium. The anti-collision early warning method comprises the steps that image information and radar information are acquired; determining a main lane line in the vehicle driving direction according to the image information; the image information and the radar information are fused, obstacles in the main lane line are determined, and motion parameters of the vehicle and the obstacles are obtained; calculating the predicted collision time of the vehicle and the obstacle according to the motion parameters; the braking time of the vehicle is calculated, and if the predicted collision time is smaller than the braking time, early warning information is sent out. According to the invention, the accuracy of anti-collision early warning of the vehicle can be improved.
本申请提供一种防撞预警方法、车载装置及存储介质,所述包括:获取影像信息以及雷达信息;根据影像信息确定车辆行驶方向上的主车道线;对影像信息以及雷达信息进行融合,确定在主车道线内的障碍物以及获取车辆与障碍物的运动参数;根据运动参数计算车辆与障碍物的预计撞击时间;计算车辆的制动时间,若预计撞击时间小于制动时间,发出预警信息。本申请能够提高对车辆的防撞预警的准确度。
