本发明公开了基于时空轨迹重构异常道路高精地图快速生成系统与方法,所述系统包括:路侧传感单元、车载单元和大数据服务平台,所述路侧传感单元获取行驶车辆的动态与特征信息并采集路况与交通状态信息,车载单元获取车辆本身轨迹信息与周围环境信息,采集的数据均传送至大数据服务平台进行逆向时空轨迹重构,重构后的数据与此区域原始高精地图数据进行差分对比,将差异之处与原有高精地图叠加生成全新道路高精地图,并将路侧传感单元和车载单元采集的异常道路信息融合至全新道路高精地图,在地图中标注出异常位置,供多个用户端进行调用。本发明解决了现有地图不能及时反馈道路突发状态,不能快速生成新的通行方案的问题。

    The invention discloses a rapid generation system and method for reconstructing an abnormal road high-precision map based on a space-time trajectory. The system includes: a roadside sensing unit, a vehicle-mounted unit and a big data service platform. The roadside sensing unit acquires dynamic and characteristic information of a running vehicle and acquires road condition and traffic state information. The vehicle-mounted unit obtains track information of a vehicle and surrounding environment information. The collected data is transmitted to the big data service platform for reverse space-timetrajectory reconstruction; difference comparison is carried out on the reconstructed data and original high-precision map data of the region; and a difference is superposed with an original high-precision map to generate a brand-new road high-precision map, abnormal road information acquired by the roadside sensing unit and the vehicle-mounted unit are fused to the brand-new road high-precision map, and an abnormal position in the map is marked and thus can be called by a plurality of clients. According to the invention, the problems that the existing map cannot feed back the road emergency state in time and cannot quickly generate a new passing scheme are solved.
