The embodiment of the invention provides a vehicle early warning method and device, equipment and a storage medium. The method comprises the following steps: acquiring a pavement image of a road ahead of a vehicle; obtaining a target lane line in the road surface image, and a relative distance and a relative speed between an obstacle in front of the vehicle and the vehicle by using a deep learning model; correcting the relative distance according to the width of the target lane line near the vehicle and the width of the target lane line near the front obstacle in the pavement image; correcting the relative distance according to the size of a front obstacle surrounding frame in the multi-frame road surface image; according to the corrected relative distance and relative speed, whether the front obstacle has a collision risk with the vehicle or not is judged; and if yes, outputting collision risk warning information. According to the method, only the camera needs to be installed on the vehicle, the number of needed sensors is small, the system cost is low, maintenance is easy, and meanwhile the collision risk prediction precision is high.
本申请实施例提供一种车辆预警方法、装置、设备及存储介质。该方法包括:获取车辆行驶前方道路的路面图像;利用深度学习模型,获取路面图像中的目标车道线、车辆前方障碍物与车辆的相对距离及相对速度;根据路面图像中车辆附近目标车道线的宽度、前方障碍物附近目标车道线宽度对相对距离进行校正;根据多帧路面图像中前方障碍物包围框的大小对相对距离进行校正;根据校正后的相对距离、相对速度,判断前方障碍物与车辆是否存在碰撞风险;若是,则输出碰撞风险警示信息。该方法仅需要在车辆上安装摄像头,需要的传感器数量较少,系统成本低,维护容易,同时具有较高的碰撞风险预测精度。
