The invention provides a lane-level safety early warning method and system based on the vehicle-road cooperation technology, and relates to the technical field of automobile early warning and intelligent traffic, and the method comprises the steps: obtaining the position information and time information of a vehicle; based on a preset shooting distance, acquiring a road image in front of the vehicle; judging the image of the road in front of the vehicle, determining whether a road abnormal condition exists or not, judging position information of the road abnormal condition relative to the vehicle, and generating abnormal reminding information; matching with a preset control strategy according to the abnormal road condition, and generating a control instruction; and performing prompt content matching, and sending prompt information to a related vehicle. According to the invention, the technical problem in the prior art that the accuracy of early warning for upstream vehicles on different lanes is low and traffic jam is easily caused can be solved. The technical target of continuously monitoring the road condition is achieved, and the technical effects of finding the dangerous condition of the road in time and determining the lane to which the road belongs are achieved.
本申请提供了一种基于车路协同技术的车道级安全预警方法及系统,涉及汽车预警和智能交通技术领域,该方法包括:获取车辆的位置信息、时间信息;基于预设拍摄距离,采集车辆前方道路图像;对车辆前方道路图像进行判定,确定是否存在道路异常情况,判断道路异常情况相对于车辆的位置信息,生成异常提醒信息;根据异常道路情况与预设控制策略进行匹配,生成控制指令;进行提示内容匹配,发送提示信息至相关车辆。通过本申请可以解决现有技术中由于对不同车道上游车辆的预警的精确度较低,容易造成交通拥堵的技术问题。实现了对道路情况持续监测的技术目标,达到能够及时发现道路危险情况并确定所属车道的技术效果。
