Unmanned aerial vehicle cluster autonomous cooperation system and method based on photoelectric navigation

Abstract

The invention relates to the technical field of unmanned aerial vehicle navigation, in particular to an unmanned aerial vehicle cluster autonomous cooperation system and method based on photoelectric navigation. The system comprises a photoelectric signal acquisition unit, a map loading unit, an auxiliary navigation unit, a cooperation unit, a controller and a memory. According to the invention, the arranged photoelectric signal sensor emits and receives light beams, then the photoelectric signal receiving module receives photoelectric signals generated by the light beams, the height calculation module is combined to accurately calculate the distance between the unmanned aerial vehicle and an obstacle, and timely adjustment is carried out according to the distance, so that the obstacle is avoided in time; the problem that the unmanned aerial vehicles cannot be accurately controlled when no GPS signal exists or the signal is weak is solved, in addition, synchronization of unmanned aerial vehicle cluster signals is carried out through the cooperation unit, and therefore synchronous avoidance of the multiple unmanned aerial vehicles is achieved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle navigation, in particular to an autonomous coordination system and method for unmanned aerial vehicle clusters based on photoelectric navigation. Background technique [0002] Nowadays, drones are not only used in the military industry, but also in agriculture and photography. Generally, drones used in these two industries are controlled by remote controls, but whether they are used in agriculture or Photography has higher and higher requirements for UAVs, for example: irrigation of rice fields in the mountains or shooting of mountains and rivers in agriculture, so in these two cases the requirements for UAV evasion will be It is getting higher and higher, and sometimes multiple drones are required to form a cluster to work synchronously. [0003] For the sake of safety, many drones are equipped with GPS navigation, so that if the remote control cannot be controlled, the drone can...

AI Technical Summary

Problems solved by technology

[0003] For the sake of safety, many drones are equipped with GPS navigation, so that if the remote control cannot be controlled, the drone can navigate back according to the pre-loaded map, but the GPS signal is easily interfered in the mountains. In this way, the UAV cannot return smoothly, or the GPS signal is weak, so that the UAV cannot avoid obstacles in time during the return process.
