Embodiment 1

[0028] Such as Figure 1-2 Shown, a UAV obstacle avoidance method, comprises the following steps:

[0029] 1) Real-time detection of obstacles in the forward direction;

[0030] 2) If there is an obstacle, establish the obstacle area where the obstacle is located, and collect flight information;

[0031] 3) Establish a collision avoidance route and a route to restore the original flight path according to the obstacle edge and flight information closest to the UAV in the obstacle area;

[0032] 4) Before the UAV enters the collision avoidance zone, adjust the obstacle avoidance speed and obstacle avoidance course;

[0033] 5) After avoiding obstacles, adjust the flight speed and flight angle again according to the route to restore the original flight path.

[0034] In this embodiment, the method for establishing the obstacle zone includes the following steps:

[0035] Ⅰ) Get the maximum width of the obstacle;

[0036] Ⅱ) Establish a spherical area based on the maximum widt...

Abstract

The invention discloses a drone obstacle avoidance method. The drone obstacle avoidance method comprises the following steps of 1, probing an obstacle in the heading direction in real time; 2, if theobstacle exists, establishing an obstacle area of the obstacle and acquiring flight information; 3, establishing a collision avoidance path and a path for restoring an original flight route accordingto the obstacle edge nearest to a drone and the flight information; 4, before the drone enters a collision avoidance behavior area, adjusting the obstacle avoidance speed and the obstacle avoidance heading; 5, after the obstacle is avoided, adjusting the flight speed and the flight angle according to the path for restoring the flight route. The drone obstacle avoidance method can be high in safety.

Description

technical field [0001] The invention relates to an obstacle avoidance method for an unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but equipment such as autopilot and program control device are installed. The personnel on the ground, on the ship, or at the remote control station of the parent aircraft track, locate, remotely control, telemeter and digitally transmit it through radar and other equipment. Under the radio control, it can take off like an ordinary aircraft or be launched into the air with a booster rocket, and it can also be taken into the air by the parent aircraft for flight. When recovering, it can automatically land in the same way as the common aircraft landing process, and can also be recovered by remote control with a parachute or a block. Can be used repeatedly. Widely ...
