SLAM technology in unmanned aerial vehicle.

Unmanned Aerial Vehicle (UAV) is an aircraft with broad application prospects, and its navigation and positioning technology development is crucial to realize autonomous flight and mission execution. This paper introduces the structure and related key technologies of SLAM technology in UAV application and looks forward to the future development direction. Regarding navigation and autonomous flight, SLAM technology can help UAVs locate and plan paths in complex environments, and support indoor cruise and task execution. In terms of 3D modeling and scene reconstruction, SLAM technology can obtain environmental information through the drone's vision and laser sensors, and build an accurate 3D map. In addition, SLAM technology can also be applied to search and rescue missions, drone formation and collaborative work, and visual augmented reality. The advancement of SLAM algorithms and hardware technology has made the application of SLAM on UAVs more common and mature, providing more innovation and application opportunities for UAVs' autonomy, perception capabilities, and collaborative work capabilities.
