The invention provides a lane departure early warning method and device, a storage medium and an automobile data recorder. The method comprises the following steps: obtaining a current vehicle front image and current driving information, and extracting a current lane line position and a current vehicle head position from the current vehicle front image; calculating target time required for the vehicle to cross a lane line according to the current lane line position, the current vehicle head position and the current driving information; judging whether the target time is less than a time threshold; if so, sending out a lane departure early warning prompt, and marking the current image in front of the vehicle as an alarm frame image; putting the alarm frame image and a vehicle front image acquired thereafter into a data buffer pool; and when the number of the images in the data buffer pool reaches a preset number, packaging and uploading the images in the data buffer pool and emptying the data buffer pool. Traffic accidents caused by lane departure are effectively avoided; and in addition, lane early warning videos are automatically uploaded, so subsequent driver driving behavior analysis is facilitated.

    本发明提供一种车道偏离预警方法、装置、存储介质及行车记录仪,所述方法包括:获取当前车辆前方图像及当前行驶信息,并从当前车辆前方图像中提取出当前车道线位置及当前车头位置;根据当前车道线位置、当前车头位置及当前行驶信息,计算出车辆越过车道线所需的目标时间;判断目标时间是否小于时间阈值;若是,则发出车道偏离预警提示,并将当前车辆前方图像标记为报警帧图像;将报警帧图像及其之后获取的车辆前方图像放入数据缓冲池中;当数据缓冲池中的图像达到预设数量时,将数据缓冲池中的图像打包上传并清空数据缓冲池。本发明有效避免因车道偏离而导致发生交通事故,此外还自动上传车道预警视频,方便后续对驾驶员驾驶行为进行分析。
