Problems solved by technology

[0003] However, in view of the fact that the UAV lacks a real-time position of the obstacle during the specific flight process, it can specifically distinguish whether the corresponding obstacle is a prohibited immovable obstacle or an active obstacle, and different obstacles are given according to different obstacles. Obstacle avoidance reflection, effectively avoiding obstacles while making small movements; in order to realize this technical idea, a technical solution is now provided

Abstract

The invention discloses an unmanned aerial vehicle automatic detection obstacle avoidance system. The system comprises an uninterrupted scanning unit, a co-processing module, a distance measurement unit, an identification module, an instruction input unit, a processor, a rule base, a recording unit, an intelligent device and a flight control unit. According to the invention, the uninterrupted scanning unit performs uninterrupted scanning on the flight front of the unmanned aerial vehicle, when an obstacle is detected to exist in front, the uninterrupted scanning unit returns obstacle information to the co-processing module, the obstacle information comprises an obstacle signal and direction information, and the direction information is the direction of the obstacle; and the co-processing module receives the obstacle information transmitted by the uninterrupted scanning unit, and then automatically performs obstacle analysis on the obstacle information through combination with the distance measuring unit and the identification module; and whether the corresponding obstacle is a fixed obstacle or a movable obstacle is judged.

Description

technical field [0001] The invention belongs to the field of obstacle avoidance, relates to an unmanned aerial vehicle obstacle avoidance technology, in particular to an automatic detection and avoidance system of an unmanned aerial vehicle. Background technique [0002] The patent with publication number CN109032182A discloses a UAV obstacle avoidance system and control method based on millimeter wave radar, which belongs to the UAV obstacle avoidance system field.
