Obstacle avoiding method and device for unmanned aerial vehicle

Abstract

The invention discloses an obstacle avoiding method for an unmanned aerial vehicle, which is applied to a controller arranged on the unmanned aerial vehicle. A first detector mounted in front of the unmanned aerial vehicle always points to the connection direction of the unmanned aerial vehicle and a target point. When the first detector detects that an obstacle is located on the connection direction, each of other detectors respectively rotates and detects to the other set detection directions along the connection direction. The method comprises the following steps of: obtaining the detectiondata of each detector; determining whether an obstacle is located in each detection direction; and adjusting the unmanned aerial vehicle from the connection direction to a first detection direction when determining that the first detection direction is unobstructed, controlling the unmanned aerial vehicle to fly in the connection direction until determining that the connection direction is unobstructed by the detection data of the first detector. By applying the technical solution provided by the embodiment of the invention, the effective and autonomous obstacle avoidance of the unmanned aerial is realized, the risk of the unmanned aerial crash is reduced, and the flight safety of the unmanned aerial is enhanced. The invention also discloses an obstacle avoiding device for the unmanned aerial vehicle, which has corresponding technical effects.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an obstacle avoidance method and device for an unmanned aerial vehicle. Background technique [0002] In recent years, UAV technology has developed rapidly. It is not only used in the military field, but also in the civilian field. Application of drones for traffic monitoring, etc. [0003] Although UAVs have been more and more widely used, UAV-related technologies are not very mature and are still in the stage of perfection. UAV crashes occur from time to time, causing great economic losses and threatening the ground at all times. personnel safety. A large part of the reason for the drone crash is the weakness of the obstacle avoidance link. [0004] How to realize the effective autonomous obstacle avoidance of UAV is a technical problem urgently needed to be solved by those skilled in the art. Contents of the invention [0005] The purpose of the present ...
