Description

technical field [0001] The invention belongs to the algorithm field of unmanned aerial vehicle cluster control strategy planning, and in particular relates to an unmanned aerial vehicle multi-machine collaborative mapping positioning system. Background technique [0002] As a new technology, UAV (Unmanned Aerial Vehicle, UAV) can play an important role in a variety of scenarios due to its flexible maneuverability, low cost, and less constraints on the ground terrain, especially in 3D point cloud mapping. Environmental impact is small. In order to quickly realize high-precision mapping in a complex 3D scene environment, the collaborative control of multiple UAVs and high-precision mapping are still a difficult point. For UAV multi-machine collaboration, it is still difficult to solve the overall coordination of collaborative mapping, task assignment and path planning in a specific area, so that the optimal allocation of UAV resources cannot be quickly realized.
