Abstract

The present invention relates to an unmanned aerial vehicle obstacle detection device and method, more specifically, there is a secondary camera between a pair of stereo cameras, the image captured by the secondary camera is changed based on the obstacle event, and based on the The captured images and the images of the pair of stereo cameras are used to detect obstacles.

Description

technical field [0001] The present invention aims at detecting obstacles for the free flight of UAVs, and relates to an obstacle detection system and method that combines a physically controllable additional camera with a stereo camera. Background technique [0002] With the gradual development of UAV technology, from the manual control using the manipulator, the UAV technology for free flight and specific tasks is being developed in which the UAV autonomously judges the surrounding environment. To this end, research on techniques for detecting and avoiding obstacles on the flight path to prevent collisions of drones during free flight is actively being conducted. At present, the obstacle detection of UAV adopts the method of using various sensors such as stereo camera, laser radar and ultrasonic wave alone or in combination. [0003] In particular, the obstacle detection system based on the stereo camera can build an obstacle avoidance system at a lower price than the expe...
