Extensible laser ranging obstacle avoidance system

The invention provides an extensible laser ranging obstacle avoidance system, and belongs to the technical field of obstacle avoidance detection of robots or unmanned aerial vehicles, the extensible laser ranging obstacle avoidance system is designed for unmanned systems such as unmanned aerial vehicles, robots and the like, and the extensible laser ranging obstacle avoidance system has relatively strong electromagnetic wave and ambient light inhibition performance, and can be applied to the field of obstacle avoidance detection of the robots or the unmanned aerial vehicles. The obstacle information of the surrounding environment of the unmanned system can be effectively monitored in real time. And different numbers of detection units are assembled according to system requirements, so that the conditions of system obstacle avoidance blind areas, obstacle detection failures and the like are prevented, and the safety and reliability of the unmanned system are effectively improved. The method can be widely appli
