The invention discloses a vehicle collision early warning method based on vehicle-road cooperation trajectory prediction, and the method comprises the following steps: a vehicle end sensor and a road end sensor not only can provide own related information, but also can detect related information of an object in an accessory range; each vehicle on the road is provided with a GPS receiver and sends the data of the vehicle to the roadside end; the road end is provided with a laser radar and a visual sensor, so that the target can be tracked, and the target in the range can be effectively tracked by using a target detection and tracking algorithm; in order to reduce the time complexity of the algorithm in the subsequent fusion stage, the data is sorted and deduplicated; fusing the GPS track and the visual tracking track; predicting the trajectory of the target to realize early warning of future traffic accidents; and early warning of vehicle collision is realized by predicting whether the trajectory has a possible intersection point in the same coordinate system or not. According to the invention, possible traffic collision accidents can be predicted quickly, accurately and efficiently.
本发明公开了一种基于车路协同轨迹预测的车辆碰撞预警方法,包括如下步骤,车端及路端感知器不仅可以提供本身的相关信息,还可以检测附件范围内物体有关信息;道路上每辆车都安装GPS接收器,并向路侧端发送本车数据;路端装有激光雷达和视觉传感器,可以实现对目标的跟踪,利用目标检测与跟踪算法,对范围内的目标进行有效的跟踪;为了降低后续融合阶段算法的时间复杂度,对数据进行了排序以及去重操作;GPS轨迹和视觉跟踪轨迹的融合;预测目标的轨迹实现对未来交通事故的预警;通过预测的轨迹在相同坐标系内有无可能出现的交汇点,实现对车辆碰撞的预警。本发明能够快速准确高效的预测可能发生的交通碰撞事故。
