Abstract
The present invention discloses a ranging obstacle avoidance instrument and a ranging obstacle avoidance method for an unmanned aerial vehicle. The ranging obstacle avoidance instrument includes: a grating emitter for emitting grating onto an obstacle; a camera for shooting a grating image emitted onto the obstacle; a grating processor, connected with the camera and used for processing the grating image shot by the camera, wherein the grating processor judges the distance between each portion of the obstacle and the ranging obstacle avoidance instrument by measuring a distance value between pixel points of the grating image shot by the camera and depending on a proportion of the distance value to an actual distance. The technical problems of low measurement result accuracy and poor anti-jamming capability of the ranging obstacle avoidance instrument in the prior art are solved, and the technical effects of high measurement result accuracy and strong anti-jamming capability of the ranging obstacle avoidance instrument are achieved.
