The invention relates to the technical field of air traffic management, in particular to a flight path planning method applied to a low-altitude airspace, and the method comprises the following steps: obtaining airspace data and flight plan data which represent an air region and flight time and position; the air area is divided into a plurality of grids, each edge of each grid is provided with an entrance point and an exit point, the entrance point is an entrance for the unmanned aerial vehicle to enter the current grid, and the exit point is an exit for the unmanned aerial vehicle to leave the current grid; determining all entry points and exit points as network nodes of the air area; generating a directed graph according to the network nodes and the flight plan data; searching the directed graph according to the flight plan data to obtain a flight path meeting the flight plan, and taking the flight path as a final planned flight path; the flight path planned by the method can reduce complex flight and conflicts, improve flight safety and improve flight path planning efficiency.
本发明涉及空中交通管理技术领域,具体涉及一种应用于低空空域的航迹规划方法,包括以下步骤:获取表示空中区域以及飞行的时间和位置的空域数据和飞行计划数据;将空中区域划分为多个栅格,在每个栅格的每条边上均设置一个入口点和一个出口点,入口点为无人机进入当前栅格的入口,出口点为无人机离开当前栅格的出口;将所有入口点和出口点确定为空中区域的网络节点;根据网络节点和飞行计划数据,生成有向图;根据飞行计划数据对有向图进行搜索,获取满足飞行计划的飞行路径,作为最终规划的航迹;本发明规划的航迹能够减少复杂飞行、冲突提高飞行安全性、提高航迹规划效率。
