The invention discloses an underground parking lot positioning and navigation method and system, and relates to the technical field of navigation, and the method comprises the steps: generating a driving route according to an end point coordinate, and uploading the driving route to a cloud; obstacles in the driving path are detected, and then the driving path is made again according to the current position; the unmanned aerial vehicle ascends to a specified height, overlooks the driving route of the vehicle, and re-plans the route according to the overlooks image; the vehicle moves along the travel route and detects the environment around the route, after which environmental data is generated on the re-planned route. According to the underground parking lot positioning and navigation method and system, the unmanned aerial vehicle is adopted for high-altitude assistance, and then the unmanned aerial vehicle simulates the movement of the vehicle, so that the technical problem that the path planning is too idealized in the path planning process of the existing vehicle is effectively solved, accurate obstacle avoidance is further realized, and the positioning and navigation efficiency of the underground parking lot is improved. And meanwhile, the effectiveness and accuracy of route planning can be improved, and advancing errors of vehicles are avoided.

    本发明公开了一种地下停车场定位与导航方法与系统,涉及导航技术领域,根据终点坐标生成行驶路线,再将行驶路线上传至云端;检测行驶路径中的障碍物,再根据当前位置重新制定行驶路线;无人机上升到达指定高度,俯瞰车辆的行驶路线,并根据俯瞰图像重新规划路线;车辆沿着行驶路线移动,并检测路线周围的环境,之后将环境数据生成在重新规划的路线上。本发明所述的一种地下停车场定位与导航方法与系统,由于采用了无人机进行高空协助,再由无人机模拟车辆的移动,所以,有效解决了现有的车辆在路径规划过程中,路径规划过于理想化的技术问题,进而实现了精准的避障,同时还能提高路线规划的有效性和准确性,避免车辆出现行进误差。
