The invention belongs to the field of vehicles, and discloses a driving early warning method, device and equipment and a storage medium. The method comprises the following steps: determining a to-be-detected target frame according to an environment image collected by a camera; selecting a to-be-detected point from the to-be-detected target frame, and determining a linear distance between a to-be-detected target and the current vehicle according to the to-be-detected point; determining an included angle between the to-be-detected target and the current vehicle; determining a longitudinal distance between the to-be-detected target and the current vehicle according to the included angle and the linear distance; and determining collision time according to the longitudinal distance and the relative movement speed of the to-be-detected target and the current vehicle, and performing driving early warning according to the collision time. Compared with an existing mode that the vehicle is improved, and more sensors are used around the vehicle body to recognize obstacles around the vehicle, the above mode can improve the vehicle early warning efficiency.
本发明属于车辆领域,公开了一种行车预警方法、装置、设备及存储介质。该方法包括:根据摄像头采集到的环境图像确定待检测目标框;从所述待检测目标框中选取待测点,并根据所述待测点确定待检测目标与当前车辆的直线距离;确定所述待检测目标与所述当前车辆之间的夹角;根据所述夹角和所述直线距离确定所述待检测目标与所述当前车辆的纵向距离;根据所述纵向距离和所述待检测目标与所述当前车辆的相对运动速度确定碰撞时间,并根据所述碰撞时间进行行车预警。相对于现有的对车辆进行改进,在车身周围使用的较多的传感器识别车辆周围障碍物的方式,本发明上述方式能够提高车辆预警效率。
