The invention discloses a lane-level road danger early warning system and method based on a vehicle-road cooperation technology, and belongs to the field of automobile early warning and intelligent traffic. The method comprises the steps that firstly, a vehicle collects a driving road surface image through a vehicle-mounted camera sensor, and the dangerous conditions, such as road damage, obstacles and low-adhesion road surfaces, which are not beneficial to vehicle driving, existing on the road surface are analyzed; then determining the lane where the vehicle is located by using a Beidou navigation positioning system, analyzing the lane where the road is dangerous by using an image processing algorithm, and dividing the lane into a dangerous lane and a safe lane; and finally, the information communication system is used for carrying out different levels of early warning on the vehicles on the dangerous lane and the safe lane. According to the invention, before the vehicle arrives at the dangerous road area, reasonable early warning and prompt are given according to the sensor detection information of the downstream vehicle, and accurate early warning is realized, so that the probability of occurrence of safety accidents is reduced.
本发明公开了一种基于车路协同技术的车道级道路危险预警系统及方法,属于汽车预警和智能交通领域;其中方法包括:首先车辆通过车载摄像头传感器采集行驶路面图像,分析路面存在的不利于车辆行驶的危险情况,例如道路损坏、障碍物和低附着路面等情况;然后利用北斗导航定位系统确定车辆本身所在的车道,利用图像处理算法分析出道路危险情况所在的车道,划分出危险车道和安全车道;最后利用信息通讯系统对危险车道和安全车道的车辆进行不同等级的预警。本发明实现了车辆到达危险道路区域前,根据下游车辆的传感器探测信息给出合理的预警和提示,做到精准预警,从而降低安全事故的发生概率。
