Title:

UNMANNED AERIAL VEHICLE RETURN METHOD AND APPARATUS, UNMANNED AERIAL VEHICLE, AND STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2022/127754

Kind Code:

A1

Abstract:

An unmanned aerial vehicle (600) return method and apparatus, an unmanned aerial vehicle (600), and a storage medium (620). The unmanned aerial vehicle (600) return method comprises: calculating the remaining flight duration and a return duration of the unmanned aerial vehicle (600) according to a preset period during operation of the unmanned aerial vehicle (600) in a preset operation path (S101); determining whether the remaining flight duration is greater than the return duration (S102); if yes, obtaining a target return point on the preset operation path, and determining, according to the current position and the target return point, whether to return the step of calculating the remaining flight duration and the return duration according to the preset period (S103); if not, taking the current position as a target return point (S104); and when the flight reaches the target return point, controlling the unmanned aerial vehicle (600) to fly from the target return point to a return destination (S105). The operation efficiency and the battery energy utilization rate of the unmanned aerial vehicle (600) can be improved, and the unmanned aerial vehicle (600) can return with enough power, thereby ensuring the safe return of the unmanned aerial vehicle (600).
