The invention discloses a radar target intersection queuing keeping and track association method and system, and relates to the field of intelligent traffic management, and the method comprises the steps: carrying out the target state obtaining through comprehensively considering the traffic lane number, the traffic lane width, the stop line position and other intersection topological information and detection data, and combining the position, the vehicle type, the reflection intensity and other target detection results, the bipartite graph matching algorithm is adopted to associate the motion state information of the moving target and the queuing target in the scene of switching from the static state to the starting state of the vehicle, so that the association accuracy of tracks between the moving target and the queuing target can be ensured; and meanwhile, short-time prediction is performed on the static target, and retention is performed in combination with the stop line position and the front vehicle data, so that distortion caused by long-time prediction on the low-speed and static target is prevented, false targets formed by setting fixed retention time are avoided, and the correlation accuracy of the tracks between the moving target and the queuing target is further improved.
本发明公开一种雷达目标路口排队保持与轨迹关联方法及系统,涉及智能交通管理领域,包括:综合考虑车道数量、车道宽度、停止线位置等路口拓扑信息和检测数据进行目标状态获取,并结合位置、车型、反射强度等目标检测结果,采用二分图匹配算法对车辆静止到启动切换场景下的运动目标和排队目标的运动状态信息进行关联,可以保证运动目标和排队目标之间轨迹的关联准确度;同时对静止目标进行短时预测,并结合停止线位置和前车数据进行保留,防止对低速和静止目标长时间预测导致的失真,避免设置固定保留时间形成的虚假目标,进一步提升了运动目标和排队目标之间轨迹的关联准确度。
