Problems solved by technology

However, the existing ultrasonic-based obstacle avoidance system has relatively strict requirements on obstacles. If the material of the obstacle is not a flat and smooth solid object, there will be problems in the reflection and reception of ultrasonic waves, which will cause the drone to be unable to effectively avoid obstacles

Abstract

The invention discloses an obstacle avoidance device for unmanned aerial vehicle and its method for obstacle avoidance with the object to solve the technical problem that the unmanned aerial vehicle can not effectively avoid the obstacle in the prior art. The obstacle avoidance device for unmanned aerial vehicle comprises a detector module, an information processing module, a data fusion module and a flight control module. All are connected in the above mentioned order. The detector module comprises an ultrasonic unit and a binocular vision unit, wherein the ultrasonic unit and the binocular vision unit are used for simultaneously obtaining obstacle information. The information processing module is used for processing the obstacle information obtained by the ultrasonic unit to obtain the obstacle distance information and processing the obstacle information obtained by the binocular vision unit to obtain obstacle depth information. The data fusion module is used to integrate the obstacle distance information and the obstacle depth information to obtain the comprehensive obstacle information, and to make the flight control module control the unmanned aerial vehicle to avoid obstacles according to the comprehensive obstacle information. The invention is used for obstacle avoidance of an unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an obstacle avoidance device and an obstacle avoidance method for an unmanned aerial vehicle. Background technique [0002] With the rapid development of the UAV industry, the application of UAVs is becoming wider and wider. In order to improve the safety of UAVs, the research on UAV obstacle avoidance systems and methods is particularly important. [0003] At present, the main UAV obstacle avoidance system is based on the ultrasonic obstacle avoidance system, which is to install a directional ultrasonic transmitter and receiver on the UAV and connect it to the flight control system of the UAV. However, the existing ultrasonic-based obstacle avoidance system has relatively strict requirements on obstacles. If the material of the obstacle is not a flat and smooth solid object, there will be problems in the reflection and reception of ultrasonic waves, which will c...
