The invention discloses a multi-camera lane line departure early warning method and system for a commercial vehicle. The method comprises the steps that the commercial vehicle collects road images including lane line visual information in front and at the rear side through multiple cameras; based on the acquired image, detecting the lane line position of the front-view camera by adopting deep learning, and detecting the lane line positions of the rear-view cameras on the two sides by adopting digital image processing; the lane line deviation distance and deviation speed are calculated according to the lane line position information, finally, the early warning level is judged by combining the two calculation results, and corresponding early warning information is sent; the system comprises an information acquisition module, a detection module and an early warning module. According to the lane line departure early warning method, the departure distance and the departure speed of the lane line and the vehicle are calculated at the same time, the alarm level is divided into multiple levels by combining the departure distance and the departure speed, the departure condition can be reasonably judged, corresponding alarm information is sent out according to different conditions, and the driving comfort is improved while the driving safety is guaranteed.

    一种商用车多相机车道线偏离预警方法及系统,所述方法包括商用车多相机采集前方及侧后方包含车道线视觉信息的道路图像;基于采集的图像,采用深度学习检测前视相机车道线位置,采用数字图像处理检测两侧后视相机车道线位置;根据车道线位置信息计算车道线偏离距离及偏离速度,最后结合二者计算结果判断预警级别,并发送相应的预警信息;所述系统包括信息采集模块、检测模块和预警模块;本发明所提出的车道线偏离预警方法同时计算车道线与本车的偏离距离及偏离速度,并结合二者将警报级别划分为多级,可合理判定偏离情况,根据不同情况发出相应的报警信息,在保证驾驶安全性的同时提高了驾驶舒适性。
