The invention discloses a vehicle path reconstruction method based on license plate recognition and a checkpoint state. According to the method disclosed by the invention, vehicle path restoration and traffic restoration caused by missing detection or no checkpoint can be completed with relatively high precision, the method has good performance in an actual case, and compared with the existing technical scheme, the method disclosed by the invention has the following beneficial effects: key nodes through which a large number of vehicles pass can be obtained through data of the checkpoint, so that the vehicle path restoration and traffic restoration can be realized; and then key nodes are connected in series by using an algorithm to obtain a path with relatively high precision. In addition, the OD of the motor vehicle can be directly obtained based on the analysis of the checkpoint data, and errors caused by division in a traditional mode are avoided.
本发明公开了一种基于车牌识别和卡口状态的车辆路径重构方法。本发明公开的方法可以较高精度地完成漏检或未安设卡口造成的车辆路径还原和流量修复,在实际的案例中有良好的表现,与现有技术方案相比,本发明具体具有如下有益效果:本发明通过卡口的数据可以获取大量车辆经过的关键节点,然后利用算法串联关键节点即可得到精准度较高的路径。另外,基于卡口数据的分析可以直接得到机动车的OD,避免了传统方式划分的误差。
