Unmanned aerial vehicle autonomous landing control method and system based on multiple two-dimensional codes

Abstract

The invention relates to an unmanned aerial vehicle autonomous landing control method and system based on multiple two-dimensional codes, belongs to the technical field of unmanned aerial vehicle autonomous landing, and solves the problems of low landing precision and poor reliability of an unmanned aerial vehicle in a long-distance landing process in the prior art. The method comprises the following steps: constructing a two-dimensional code for landing; wherein the two-dimensional code for landing comprises a plurality of nested two-dimensional codes; based on each nested two-dimensional code in the two-dimensional codes for landing, constructing a landing state machine in the landing process of the unmanned aerial vehicle; and based on the measurement precision information of each nested two-dimensional code and the landing state machine, determining the pose information of the unmanned aerial vehicle in the landing process, and further performing flight control of the unmanned aerial vehicle.
