Title:
3D-MAP-BASED FLIGHT CONTROL METHOD AND SYSTEM FOR UNMANNED AIRCRAFT, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/067133
Kind Code:
A1
Abstract:
A 3D-map-based flight control method and system for an unmanned aircraft, and a medium. The method comprises: acquiring 3D map data and positioning data of an unmanned aircraft (S102); on the basis of several preset reference points in the 3D map data and in combination with the positioning data, performing identification to obtain location data of the unmanned aircraft in the 3D map data (S104); acquiring panoramic image data of the unmanned aircraft, and correcting a flight path of the unmanned aircraft on the basis of the panoramic image data and in combination with the reference points (S106); and acquiring spatial data of the unmanned aircraft during flight, and performing obstacle avoidance control for the flight of the unmanned aircraft in combination with the 3D map data (S108). By means of the present method and the system, positioning and flight path correction can be performed on an unmanned aircraft on the basis of 3D map data, and obstacle avoidance control can be performed during an automatic flight process of the unmanned aircraft, so as to reduce damage to the unmanned aircraft.
