Abstract

Abstract: Artificial inspection is easily limited by natural environmental factors and requires a large amount of manpower support.With the development of new technology,unmanned aerial vehicle inspection has gradually attracted attention,and its positioning accuracy directly affects the performance of the drone.In order to reduce the positioning error in the inspection process of multi-rotor unmanned aerial vehicles,and to realize real-time positioning of the inspection UAV,this paper introduces a spherical intersection ambiguous algorithm.By applying the ambiguous algorithm to RTK positioning,the uncertainty and ambiguity in the positioning process can be effectively handled,for improving the positioning accuracy of the UAV.This allows the static positioning accuracy of the unmanned aerial vehicle inspection system to the centimeter-scale,and ensures smooth continuity of the dynamic measurement of the motion trajectory.

Key words: unmanned aerial vehicle, ambiguous algorithm, high-precision positioning, RTK
