UAV ranging avoidance system based on laser radar

Abstract

The invention relates to a UAV ranging avoidance system based on a laser radar. The UAV ranging avoidance system comprises a ranging avoidance module and a control module, wherein the UAV ranging avoidance module comprises an information processing module, and an attitude recognition module, an attitude adjustment module, an information acquisition module and an avoidance execution module which are connected with the information processing module respectively; and the ranging avoidance module is installed on the outer side wall of a UAV main body, and the ranging avoidance module is connectedwith the control module in the UAV main body. The UAV ranging avoidance system aims at the UAV movement features and environmental features, only pays attention to an space region in a 90-degree sector of the horizontal plane directly in front of a flight direction of the UAV and has a certain horizontal included angle, realizes the effective detection and obstacle avoidance in a three-dimensionalenvironment, meets the requirements for lightweight UAV-borne equipment, and is simple in structure and cost-effective.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a laser radar-based ranging and avoidance system for unmanned aerial vehicles. Background technique [0002] In recent years, drones have developed rapidly. During the flight of UAVs, it is difficult to completely predict the flight environment information, and often encounter sudden threats or obstacles. At this time, the pre-planned global track path can no longer meet the requirements. In order to achieve the expected purpose, it is necessary to have the function of real-time detection and avoidance of obstacles, to be able to analyze and evaluate the path and its surrounding environment and threats, to re-plan a reasonable track path, and to coordinate the UAV to follow the specified path. Fly on the track path to avoid the obstacles ahead and continue to complete the mission. After the 1970s, researchers at home and abroad have successively proposed many r...

Problems solved by technology

After the 1970s, researchers at home and abroad have successively proposed many solutions for real-time obstacle avoidance of UAVs. The two-dimensional UAV obstacle avoidance technology has achieved fruitful results and has been widely used. Obstacle scanning and obstacle avoidance are still rarely seen in the literature
