The invention relates to the field of traffic monitoring, in particular to a multi-millimeter-wave radar vehicle track splicing method and system in a tunnel. The method comprises the following steps: carrying out space-time calibration on all millimeter wave radars in a tunnel; respectively acquiring a set of vehicle information of all vehicles at any same moment in the overlapping area of all adjacent millimeter wave radars; similarity of adjacent radar vehicle information; and inputting the similarity into a pre-trained BP network, and determining whether to splice the vehicle tracks or not according to a result. According to the method, the vehicle tracks between the millimeter wave radars are spliced by adopting a BP neural network method, and the problem that the splicing effect of the vehicle tracks in the tunnel is not ideal due to the fact that millimeter wave radar signals have a multipath effect in the tunnel, detection interference is large and monitoring data precision is insufficient is solved.
发明涉及交通监测领域,具体涉及一种隧道内多毫米波雷达车辆轨迹拼接方法及系统。所述方法包括以下步骤:将隧道内的所有毫米波雷达进行时空校准;分别获取所有相邻的毫米波雷达在重叠区域内所有车辆在任一相同时刻的车辆信息的集合;相邻雷达车辆信息的相似度;将相似度输入预训练的BP网络,根据结果决定是否对车辆轨迹进行拼接。本发明通过采用BP神经网络的方法来拼接毫米波雷达间的车辆轨迹,解决毫米波雷达信号在隧道内存在多径效应,检测干扰大,监测数据精度不足,导致隧道内车辆轨迹拼接的效果不理想的问题。
