Document Type and Number:
WIPO Patent Application WO/2019/006773
Kind Code:
A1
Abstract:
A return flight method and device for an unmanned aerial vehicle in a low electric quantity, which relates to the remote control field of unmanned aerial vehicles and can resolve the problem of the unmanned aerial vehicle failing to normally fly back caused by insufficiency of the electric quantity during a return flight. The method comprises: obtaining initial electric quantity information and an initial position of an unmanned aerial vehicle (101); when the electric quantity becomes a preset electric quantity due to the flight of the unmanned aerial vehicle, sending a return flight prompt to a user (102); computing, according to a current position and the initial position, a flight direction and path of the unmanned aerial vehicle during a return flight (103); and according to the flight direction and path during the return flight, guiding the unmanned aerial vehicle to fly back (104).
