Embodiment Construction

[0079] The implementation of the present invention will be described in detail below with reference to the drawings and examples, so as to fully understand and implement the implementation process of how to use technical means to solve technical problems and achieve technical effects in the present invention.

[0080] With the rapid development of electronic technology, UAVs are widely used in aerial photography, cargo delivery, resource exploration, route survey and other fields. The autonomous flight of drones requires automatic obstacle avoidance to ensure the flight safety of drones. Existing automatic obstacle avoidance methods can include video-based obstacle avoidance, but the current video-based autonomous obstacle avoidance method is to hover when encountering obstacles, unable to continue flying, and can only send images back to the ground station to recalculate the flight Obstacle-avoiding flight after the route, which has many restrictions on use, resulting in low ...

Abstract

The invention discloses an obstacle avoidance method for an unmanned aerial vehicle and an unmanned aerial vehicle. The method includes: acquiring a stereo disparity map of a current environment image through a binocular camera and clustering pixels in the stereo disparity map , to obtain multiple clustering regions. Based on each cluster area, calculate the flight distance from the environment area corresponding to each cluster area to the drone. By judging whether the flight distance between each environmental area and the UAV is greater than the distance threshold, the UAV is selected from any environmental area whose flight distance is greater than the distance threshold, and calculates the distance the UAV turns to. The rotation angle of any one of the above-mentioned flying-around areas, and control the drone to fly around according to the rotation angle. The invention realizes the autonomous obstacle-avoiding and circumventing flight of the UAV, and improves the flight efficiency.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to an obstacle avoidance method for an unmanned aerial vehicle and an unmanned aerial vehicle. Background technique [0002] With the rapid development of drone technology, drones have been widely used in aerial photography, cargo delivery, resource exploration, route survey and other fields. Since there is no special personnel to control the flight of the UAV during the flight, the UAV needs to fly autonomously according to the planned route, because it is difficult to avoid the obstacles encountered in the actual flight when planning the route. [0003] The drone owner can avoid obstacles encountered in flight based on the video-based autonomous obstacle avoidance method. The method uses the camera carried by the UAV to capture images of the surrounding environment, and based on the captured images, analyzes whether there is an obstacle ahead that prevents the fli...
