POSITION MEASUREMENT COMPENSATION METHOD OF CONDUIT OR LIKE

PROBLEM TO BE SOLVED: To provide a method for correcting by an analysis terminal, the position of a conduit or the like measured by using an inertia measuring device having an angle sensor. SOLUTION: A processing procedure of the analysis terminal includes steps for; calculating a position error from a value acquired by measuring the position of an end point positioned at a prescribed distance from some starting point of the conduit and a value acquired by surveying beforehand relative to the position of the end point; calculating an angle error from an angle value acquired from the angle sensor measured on the position of the end point and an angle value acquired by surveying beforehand relative to a conduit position of the end point; calculating a correction coefficient based on simultaneous equations determined beforehand from the position error and the angle error at the end point; and correcting the position of the conduit from the start point to the end point based on the correction coefficient.
