The invention provides a lane departure early warning method and device, electronic equipment and a storage medium, and relates to the technical field of driving safety assistance. The method comprises the following steps: firstly, acquiring position information of camera equipment mounted on a vehicle relative to the vehicle; establishing an image coordinate system by taking the mounting position of the camera equipment on the vehicle as an original point; under the image coordinate system, taking a driving lane of the vehicle at the current moment as a current lane, and obtaining parameter information of a target lane line of the current lane collected by camera equipment; calculating the transverse distance between the outer edge position of the front wheel of the vehicle at the current moment and the target lane line based on the parameter information of the target lane line of the lane and the position information of the camera equipment relative to the vehicle; and when the transverse distance between the outer edge position of the front wheel of the vehicle at the current moment and the target lane line meets a preset distance condition, performing early warning processing on the vehicle. According to the mode, the accuracy of lane departure early warning is improved.
本申请提供一种车道偏离预警方法、装置、电子设备及存储介质,涉及行车安全辅助的技术领域。该方法包括:先获取安装在车辆上的摄像设备相对于车辆的位置信息;然后以摄像设备在车辆上的安装位置为原点,建立图像坐标系;在图像坐标系下,将车辆在当前时刻的行驶车道作为本车道,并获取摄像设备采集到的本车道的目标车道线的参数信息;再基于本车道的目标车道线的参数信息和摄像设备相对于车辆的位置信息,计算车辆在当前时刻的前轮的外缘位置与目标车道线之间的横向距离;当车辆在当前时刻的前轮的外缘位置与目标车道线之间的横向距离满足预设距离条件时,对车辆进行预警处理。上述方式提高了车道偏离预警的准确性。
