Embodiment Construction

[0059] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0060] In related technologies for planning a path for an aircraft, a search-based path planning method performs a graph-based path search through a Dijkstra algorithm (Dijkstra algorithm) and an A-Star algorithm (abbreviated as A* algorithm). Among them, the A* algorithm searches out the shortest path from the start point to the end point in the graph by traversing the graph nodes, calculating the cost value of the graph node path consumption and heuristic estimation. However, only using the A* algorithm or the Dijkstra algorithm to search for the path of the graph does not take into account the complex business factors other than obstacles encountered by th...

Abstract

The present disclosure relates to a method, device, storage medium and electronic equipment for generating a flight path. The method includes: determining the target space according to the flight start point and the flight end point of the aircraft. There are multiple space points in the target space, and each space point Corresponding to time planning information and position information, the time planning information is used to represent the flight path that is not allowed to pass through the space point within the no-fly time period; in the process of searching for multiple target space points through the path search model, when determining In the case of the i-th target space point, according to the time planning information and position information corresponding to each space point and the flight speed of the aircraft, obtain the candidate space point required for searching the i+1 target space point; The flight path of the aircraft is generated by connecting target space points. The no-fly time can be added as a node screening factor in the candidate node search stage of the path search to improve the accuracy of the node search, thereby improving the efficiency of flight path planning.

Description

technical field [0001] The present disclosure relates to the field of artificial intelligence, and in particular, to a method, device, storage medium and electronic equipment for generating a flight path. Background technique [0002] With the development of science and technology, the application of aircraft in various industries is becoming more and more frequent. For aircraft such as drones and aircraft that support autopilot, it is necessary to plan the flight path for them in advance before use. Due to the regulations of the regulator, the aircraft needs to fly in the sky according to certain rules, rather than randomly generating flight paths. Based on business needs and the complexity of the urban geographical environment, for example, there are many building obstacles and a large number of aircraft frequently passing through the same space, etc., higher requirements are also placed on the flight path planning of the aircraft. Contents of the invention [0003] Th...
