Example Embodiment

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0016] An obstacle avoidance method based on multi-rotor UAV includes the following steps:

[0017] 1) When the drone is flying, the flight control activates the lidar detection device to detect obstacles and distance;

[0018] 2) When the lidar detection device detects an obstacle in front of the UAV, the UAV flight control controls the UAV to fly upwards vertically. The lidar detection device detects that the distance between the UAV and the obstacle is a, and then detects The distance between the drone and the obstacle is b, ...

Abstract

The invention discloses an obstacle avoidance method of a multi-rotor unmanned aerial vehicle. The method comprises the following steps that: when an unmanned aerial vehicle flies, a laser radar detection device is activated by means of flight control; when the laser radar detecting device detects obstacle occurrence in front of the unmanned aerial vehicle, an unmanned aerial vehicle flight control unit controls the unmanned aerial vehicle to make horizontal and vertical translation to calculate distance and size information of the obstacle. The method is simple and effective; the collision probability of the unmanned aerial vehicle is reduced; and the application efficiency of the battery is increased.

Description

technical field [0001] The invention relates to an obstacle avoidance method for an unmanned aerial vehicle, in particular to an obstacle avoidance method based on a multi-rotor unmanned aerial vehicle. Background technique [0002] With the continuous development of my country's drone industry, drones are more and more widely used in the civilian consumer market, such as aerial photography, environmental monitoring, geological exploration, daily entertainment, etc. Autonomous and safe flight of UAVs deserves more and more attention. Especially when the one-button return function is not enabled, that is, the UAV flies from the destination to the take-off place according to its own navigation algorithm, and realizes the mode of fully autonomous flight. If it cannot effectively avoid obstacles, the UAV will still The possibility of encountering a collision. Although the drone driver is still watching the real-time dynamics of the drone when the drone is performing a one-key ...
