Abstract

The invention discloses an unmanned aerial vehicle landing method based on the embedded two-dimensional codes. According to the method, an unmanned aerial vehicle is guided to automatically land through the embedded two-dimensional codes, descends to a certain height with a mother embedded two-dimensional code as the reference within a certain height range, and a son embedded two-dimensional codeis started when the mother embedded two-dimensional code is not within the visual range of an airborne camera, so that it is ensured that the whole descending process has a descending target. The embedded two-dimensional codes are simpler, in the landing process of the unmanned aerial vehicle, the effective information of unit area is rich, a target is not easy to lose, the recognition height range is wider, the whole landing height range of the unmanned aerial vehicle can be covered, and the landing accuracy is high.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, more specifically, an unmanned aircraft landing method based on an embedded two-dimensional code. Background technique [0002] When UAVs use visual guidance to land, they land from high altitude to the ground. Due to the high positioning accuracy requirements, the positioning accuracy of conventional GPS cannot meet the requirements, and the visual positioning technology can meet the requirements of accuracy and cost. Since the initial height of the drone landing is relatively high, generally 5-10 meters, and the height of the landing end is less than 1 meter, the field of view of the camera is required to be smaller and smaller, and the resolution of the camera and the design of landmarks have certain requirements. Require. [0003] Existing technologies all use a single QR code, or the QR code is too complex, the effective information per unit area is not enough, it is easy t...
