摘要: 针对传统人工巡检模式面临地理环境约束与气象条件制约,且存在人力资源密集型的固有缺陷,无人机智能遥感监测技术逐渐成为研究热点。其自主导航定位精度作为核心性能指标,直接影响系统在复杂地形条件下的作业效能与数据可靠性。为了减小多旋翼无人机巡检过程中的定位误差,克服多路径效应、大气干扰等因素的影响,本文引入一种基于球面交点模糊算法。通过将模糊算法用于RTK定位,可有效处理定位过程中的不确定性和模糊性,从而提高无人机的定位精度,使得无人机巡检系统静态定位精度达厘米级,动态测定运动轨迹平滑连续。

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
