Flight path repeating method and device, server and storage medium

Abstract

A flight path repeating method and device, a server and a storage medium are disclosed, the method comprising: acquiring flight state data collected by an aircraft at a plurality of flight times, andgenerating an original flight path according to the flight state data (S301); determining a safety speed of each position in the original flight path according to the original flight path (S302); andaccording to the safety speed of each position, generating a repeating trajectory, and according to the repeating trajectory, generating a control instruction for controlling the aircraft to fly alongthe repeating trajectory (S303). Uniform-speed flight of the aircraft in the repeating process can be realized while the repeating trajectory is generated.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a flight trajectory replay method, device, server and storage medium. Background technique [0002] Trajectory reenactment is very useful in the field of unmanned driving. In the trajectory replay stage, the aircraft can record the waypoints with time significance, that is, record the position, speed, acceleration and time, and then generate the replay trajectory through the optimization method, and follow the trajectory, which can realize multiple repetitions after one rehearsal flight. The trajectory replay effect obtained in this way is better, but because the recorded waypoints contain time meaning, when the original trajectory contains stop waypoints (most original trajectories include stop waypoints), the aircraft will It is difficult to drive at a constant speed in the middle of the road, which will cause unnecessary pauses in the trajecto...

AI Technical Summary

Problems solved by technology

The trajectory replay effect obtained in this way is better, but because the recorded waypoints contain time meaning, when the original trajectory contains stop waypoints (most original trajectories include stop waypoints), the aircraft will It is difficult to drive at a constant speed in the middle of the road, causing unnecessary pauses in the trajectory replay, and affecting the effect of the trajectory replay

[0003] It can be seen that with the current trajectory replay method, it is impossible to achieve a uniform replay trajectory
