Unmanned aerial vehicle return method and device, unmanned aerial vehicle and storage medium

Abstract

The embodiment of the invention discloses an unmanned aerial vehicle return method and device, an unmanned aerial vehicle and a storage medium, and the method comprises the steps: calculating the remaining flight time and return time of the unmanned aerial vehicle according to a preset period in a process that the unmanned aerial vehicle operates according to a preset operation path; determining whether the remaining flight time is greater than return time; if yes, obtaining a target return point on the preset operation path, and determining whether to return to the step of calculating the remaining flight time and return time according to the preset period or not according to the current position and the target return point; if not, taking the current position as a target return point, and flying from the target return point to the return destination when flying to the target return point; and if not, determining the current position as a target return point, and flying from the target return point to the return destination. According to the embodiment of the invention, the operation efficiency and the battery energy utilization rate of the unmanned aerial vehicle can be improved, the unmanned aerial vehicle can have enough electric quantity to return, and safe return of the unmanned aerial vehicle is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of drones, and in particular, to a method and device for returning a drone, a drone, and a storage medium. Background technique [0002] With the development of drone technology, the application fields of drones are becoming more and more extensive. For example, drones are used in aerial photography, exploration, traffic command, power inspection and agricultural plant protection and other fields. [0003] At present, drones are generally equipped with an automatic return function. For example, when an abnormality is detected in the system or the power is lower than a certain threshold, the drone will interrupt the current task and start the return function, returning from the current position to the starting point or the preset return. destination. [0004] However, there are the following problems in controlling whether the drone returns autonomously according to the remaining po...
