基于IMU传感器的地下管线三维坐标监测系统的研制

A Development of 3D Coordinates Monitoring System for Underground Pipeline Using IMU Sensor

开发了基于IMU(惯性测量单元)传感技术的地下管线三维坐标监测系统,并在PVC管道中进行试验,将该系统获得的三维坐标与实际全站仪和水准仪获得的三维坐标进行比较分析。试验结果表明,IMU传感器系统测量的水平和垂直坐标和实际管线坐标的最大误差分别为7 cm和14 cm。这个测量精度高于一般的惯性管道检测系统,因此,该测量系统有望应用于地下管线位置的测量。

The three-dimensional coordinates monitoring system to underground pipeline using IMU(Inertial Measurement Unit)sensing technique was developed and tested in PVC pipe.Three-dimensional coordinates obtained from the developed system were compared with three-dimensional coordinates obtained from using total stations and levels.when compared with the results,maximum error of the horizontal and vertical positions were 7 cm and 14 cm respectively.This measurement precision is higher than the general inertial pipeline detection and positioning system.Therefore,the developed system is expected to be utilized the underground pipeline location surveying.
