The invention discloses an abnormal parking license plate snapshot method and system based on radar alarm, and a medium, and belongs to the technical field of abnormal vehicle detection. The method comprises the following steps: a configuration preparation stage: establishing a corresponding relation between radar equipment and each scene of a dome camera, and establishing a mapping relation between map longitude and latitude and pixel coordinates of a dome camera scene based on high-precision map data; in the radar abnormal parking warning stage, the radar equipment performs abnormal parking event detection on the high-speed scene in real time, and if the target vehicle has an abnormal parking event, abnormal parking warning information of the target vehicle is output to the data storage center; and a dome camera linkage license plate capturing stage: capturing license plate information of the target vehicle, obtaining final abnormal parking alarm information, and outputting the abnormal parking alarm information to a data storage center. On the basis of radar alarm information, a linkage ball machine pull frame is amplified, complete snapshot of abnormal parking is achieved, the license plate of a vehicle can be automatically and accurately recognized, and a complete and clear evidence chain is formed.

    本发明公开了一种基于雷达告警的异常停车车牌抓拍方法、系统及介质,属于异常车辆检测技术领域。方法包括:配置准备阶段:建立雷达设备与球机各个场景的对应关系,并基于高精度地图数据建立地图经纬度与球机场景图的像素坐标的映射关系;雷达异常停车告警阶段:雷达设备实时对高速场景进行异常停车事件检测,若目标车辆出现异常停车事件,则输出目标车辆的异常停车告警信息到数据存储中心;球机联动抓取车牌阶段:抓取目标车辆的车牌信息,得到最终异常停车告警信息并输出到数据存储中心。基于雷达告警信息、联动球机拉框放大,实现异常停车的完整抓拍,能够自动、准确地识别车辆的车牌,形成完整清晰的证据链。
