The invention discloses a method for matching a roadside laser radar and a regional vehicle based on a Frechet distance. The method comprises the following steps that: the laser radar acquires information of traffic participants such as pedestrians, non-motor vehicles and motor vehicles in a measurement range; the target vehicle needing to be matched obtains traffic information data of the target vehicle according to the vehicle-mounted navigation system; the target vehicle communicates with the road side unit through the vehicle-mounted unit and sends traffic information data of the target vehicle to the road side unit; after receiving the traffic information data of all matched vehicles, the road side unit screens the sent data of the vehicles in combination with local laser radar data, calculates a matching value of the sent data of the vehicles and the laser radar data according to a discrete Frechet distance after screening, and matches the data of the vehicles and the laser radar data according to a calculation result; according to the invention, the radar data and the vehicle report data are effectively matched.

    本发明公开了一种基于Frechet距离的路侧激光雷达与区域车辆匹配的方法,包括:激光雷达采集得到测量范围内的行人、非机动车和机动车等交通参与者的信息;需要匹配的目标车辆根据车载导航系统得到自身的交通信息数据;目标车辆利用车载单元与路侧单元进行通信,将自身的交通信息数据发送给路侧单元;路侧单元接收到所有匹配车辆的交通信息数据后,结合本地的激光雷达数据,对车辆的发送数据进行筛选,筛选后根据离散Frechet距离计算得到车辆发送数据和激光雷达数据的匹配值,根据计算结果进行两者数据的匹配;本发明有效地对雷达数据和车辆上报数据进行匹配。
