Unmanned aerial vehicle, unmanned aerial vehicle return method, and control terminal

Abstract

The embodiments of the invention provide an unmanned aerial vehicle, an unmanned aerial vehicle return method, and a control terminal, and belong to the field of automatic control. The unmanned aerial vehicle return method comprises the following steps: an unmanned aerial vehicle, in a flying process, successively acquiring multiple pieces of position information at a preset frequency on a flight path and a flight height corresponding to each piece of the position information; and after a return instruction sent by a control terminal for controlling the unmanned aerial vehicle is received, the unmanned aerial vehicle, according to the multiple pieces of position information and the flight height corresponding to each piece of the position information, returning on the same route to a position identified by starting point coordinate information along a return route formed by the multiple pieces of position information. The unmanned aerial vehicle return method improves the problem of incapability of successful return due to obstacles met by a conventional unmanned aerial vehicle in an automatic return process.

Description

technical field [0001] The present invention relates to the field of automatic control, in particular to an unmanned aerial vehicle, an unmanned aerial vehicle return method and a control terminal. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft controlled by radio remote control equipment. UAVs usually have an automatic return function, so that when the UAV flies to a distant location, it will automatically fly back to the original starting point without the operator's operation. The existing automatic return method of the UAV is that the UAV directly returns along the straight-line path determined by the current position of the UAV and the original starting position. However, in the straight path determined by the current position of the drone and the original starting position, there may be obstacles that hinder the flight of the drone, making it impossible for the drone to return smo...
