Laser obstacle-avoidance system for unmanned aerial vehicle

Abstract

The invention discloses a laser obstacle-avoidance system for unmanned aerial vehicle, and the system comprises a laser assembly. The laser assembly is movably disposed on the unmanned aerial vehicle,and the unmanned aerial vehicle is also provided with a drive assembly. The drive assembly drives the laser assembly to rotate on the unmanned aerial vehicle, and the laser assembly comprises a lasertransmitter and a laser receiver. The laser transmitter transmits laser to the outside, and the laser receiver receives the laser reflected by an external obstacle and enables a laser signal to be transmitted to a control module of the unmanned aerial vehicle. The control module controls the unmanned aerial vehicle to avoid the external obstacle to fly. Through the above mode, the system can judge the obstacle through receiving the laser signal reflected by the outside, achieves the automatic avoiding of the obstacle for the unmanned aerial vehicle, is high in automation degree, is safe and reliable, and is convenient to use.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a laser obstacle avoidance system for unmanned aerial vehicles. Background technique [0002] UAVs on the market basically require human operation. If they can automatically avoid obstacles, they can fly automatically without unmanned operation in advance. If ultrasonic waves are used, they are easily disturbed. The internal structure of the aircraft is compact, which will cause a lot of interference to it, or the optical phase detection is also difficult. It is easy to be interfered by dust, or multiple cameras can be used to obtain multi-directional video images for analysis, but the cost is also high. Do you need a highly integrated chip as a support? There are also traditional radar systems, but the cost is too high and the weight is too high big. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a laser ob...
