The invention discloses a full-road-section full-time-domain vehicle-road cooperative auxiliary positioning method based on a roadside thunder-view array. The method comprises the following steps: (1) arranging a thunder-view all-in-one machine on a roadside and matching with an RSU roadside unit; (2) detecting the positioning information of a target vehicle by a radar module of the all-in-one thunder-vision machine in the thunder-vision monitoring area; (3) completing matching association of the license plate ID and the target vehicle in an association area by a thunder-vision all-in-one machine association module; (4) smooth splicing of the target vehicle information is completed in the splicing area through the Leiyu all-in-one machine splicing module, and the continuity of the information is ensured; and (5) the RSU road side unit sends the speed, the coordinates, the timestamp, the license plate ID and other information of the vehicle recorded by the thunder-vision all-in-one machine to the surroundings, and vehicle-road cooperative auxiliary positioning is completed. The method does not depend on satellite navigation and vehicle-mounted positioning technologies such as a GPS (Global Positioning System) and the like, and ensures that the vehicle can still be safely and stably positioned by utilizing a vehicle-road cooperation technology through cooperation with road infrastructures under the condition that a GPS signal fails.
本发明公开了一种基于路侧雷视阵列的全路段全时域的车路协同辅助定位方法,方法:(1)将雷视一体机布设在路侧并搭配RSU路侧单元;(2)在雷视监控区雷视一体机雷达模块检测目标车辆的定位信息;(3)在关联区雷视一体机关联模块完成车牌ID与目标车辆的匹配关联;(4)在拼接区雷视一体机拼接模块完成实现目标车辆信息的平滑拼接,确保信息的连续性;(5)RSU路侧单元将雷视一体机记录的车辆的速度、坐标、时间戳和车牌ID等信息发送到周围,完成车路协同辅助定位。本发明方法不依赖GPS等卫星导航和车载定位技术,通过与道路基础设施的协同,利用车路协同技术来确保车辆在GPS信号失效的情况下依然能够安全、稳定地进行定位。
