摘要
地下管线三维轨迹惯性定位是一种抗干扰能力强、定位精度高的地下管线定位技术。本文通过对REDUCT公司的两款惯性定位系统实验,定量分析了里程仪的误差及惯性定位系统的运动速度对其测量精度的影响,为今后工程实践提供了宝贵经验,为持续改善和提高地下管线三维轨迹惯性定位系统精度理清了思路。
The three-dimensional trajectory inertial positioning of underground pipelines is a kind of positioning technology with strong anti-interference ability and high positioning accuracy.Based on the experiments of two inertial positioning systems of REDUCT Company,this paper quantitatively analyses the error of odometer and the influence of the motion speed of inertial positioning system on its measurement accuracy,provides valuable experience for future engineering practice,and clears up the train of thought for continuously improving and improving the accuracy of three-dimensional inertial positioning system for underground pipelines.
