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

Abstract

The three-dimensional coordinates monitoring system to underground pipeline using IMU (Inertial Measurement Unit) sensing technique was developed. 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 7cm ,14cm respectively. In our Country, tolerance error of underground utility surveying is ± 30cm. Therefore, the developed system is expected to be utilized the underground pipeline location surveying .

Pipeline Bending Strain Measurement and Compensation Technology Based on Wavelet Neural Network

“…Nowadays, a geometry Pipeline Inspection Gauge (PIG) is usually adopted to locate damaged pipeline segments [7][8][9]. A PIG consists of a Data Acquisition System (DAS), an Inertial Measurement Unit (IMU), some mechanical fingers, and an odometer.…”
