Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a laser radar obstacle avoidance system and method based on an unmanned aerial vehicle. Background technique [0002] In the power supply process of the transmission line, in order to ensure the stability and safety of the power supply of the transmission line, it is very important to inspect and inspect the line. It can no longer meet the requirements, and the use of unmanned aerial vehicles to monitor the transmission line has gradually become an important means to ensure the safety of the power grid. [0003] However, during the cruising process of the UAV, obstacles may be encountered. In this case, the safety of the UAV and the normal completion of the cruising task will be greatly affected. The existing UAV obstacle avoidance Ultrasound is used to detect the distance to avoid obstacles. The defect is that the data of ultrasonic detection is unstable and inaccurate. ...

[0002] In the power supply process of the transmission line, in order to ensure the stability and safety of the power supply of the transmission line, it is very important to inspect and inspect the line. It can no longer meet the requirements, and the monitoring of transmission lines by unmanned aerial vehicles has gradually become an important means to ensure the safety of the power grid.

[0003] However, during the cruising process of the UAV, obstacles may be encountered. In this case, the safety of the UAV and the normal completion of the cruising task will be greatly affected. The existing UAV obstacle avoidance Ultrasound is used to detect the distance to avoid obstacles. The defect is that the data of ultrasonic detection is unstable and inaccurate. It can only be used within a small distance, and the safety and stability factor is not high.
