Title:
UNMANNED AERIAL VEHICLE CONTROL METHOD AND SYSTEM BASED ON SIGNAL LOSS, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/067134
Kind Code:
A1
Abstract:
An unmanned aerial vehicle control method and system based on signal loss, and a medium. A distance between an unmanned aerial vehicle and a reference point and image information of the reference point are obtained by means of a distance measurement sensing device and a camera of the unmanned aerial vehicle; then by means of a preset three-dimensional map model of the unmanned aerial vehicle, the position of the unmanned aerial vehicle in the preset three-dimensional map model is obtained, and if the unmanned aerial vehicle is on a preset unmanned aerial vehicle flight path, the unmanned aerial vehicle continues to fly; and if the unmanned aerial vehicle is not on the preset unmanned aerial vehicle flight path, the unmanned aerial vehicle is adjusted to fly to the preset unmanned aerial vehicle flight path, and then continues to fly. The position of the unmanned aerial vehicle in the preset three-dimensional map model is determined by means of a capturing and positioning system of the unmanned aerial vehicle, thereby ensuring that the unmanned aerial vehicle safely arrives at a destination or safely lands when the unmanned aerial vehicle cannot contact the outside world due to signal loss.
