Problems solved by technology
In addition, the application of integrated positioning to UAVs is also a new direction of development. Existing UAVs can navigate autonomously outdoors and complete some simple flight tasks, but they cannot operate in cluttered buildings and environments full of obstacles. It is impossible to realize high-level flight tasks under the condition of autonomous navigation flight

Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an indoor and outdoor switching navigation system for unmanned aerial vehicles. Background technique [0002] As the society enters the era of mobile Internet, indoor positioning has become a research hotspot of location-based services, and it has also opened a new era of seamless indoor and outdoor positioning. Regional positioning can no longer meet people's requirements for location-based services. People need a full range of positioning services that are not constrained by the environment, which requires positioning technology to achieve a smooth transition in different scenarios, and the purpose of indoor and outdoor combined positioning technology and seamless positioning technology is to integrate outdoor and indoor Positioning technology to meet people's higher requirements for navigation services. [0003] At present, there is no single positioning tec...
