摘要

PROBLEM TO BE SOLVED: To provide a device that can easily and highly accurately measure the inclination of a steel column without restriction on the space required for measurement.;SOLUTION: A control section 30 has an origin processing function of storing an output signal of a triaxial accelerometer 12 at a stationary state in a storage section 35 as the origin information of the three-dimensional coordinates of the measurement system. A measurement section 10 has an origin setting function of setting an output signal ω of a triaxial angular velocity sensor 11 as the zero point of the triaxial angular velocity sensor 11 at a stationary state where the Z axis of the three dimensional coordinates of the measurement system and the gravitational acceleration direction coincide with each other. The measuring section has a compensating process function of calculating data for compensating the output signal of the triaxial angular velocity sensor 11 by detecting the stationary state on the basis of a displacement of the output signal per unit time of the triaxial accelerometer 12 and by using the origin information. From the output signal of the triaxial angular velocity sensor 11 which has been set to the origin and subjected to the compensation processing, inclination information is obtained by the measurement processing function of the measurement section 10 or the control section 30.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
