INCLINATION MEASUREMENT DEVICE, INCLINATION MEASUREMENT SYSTEM, AND INCLINATION MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To allow for improvement in detection accuracy of inclination information.SOLUTION: An inclination measurement device 1c comprises: at least two atmospheric pressure variation sensors that detect a variation in atmospheric pressure and are arranged so as to be spaced at a prescribed distance along a detection direction; an inclination variation information creation unit that creates inclination variation information indicative of a variation in inclination angle of a measurement object on the basis of atmospheric pressure variation information indicative of the variation in atmospheric pressure detected by at least two atmospheric pressure variation sensors; a constant velocity inclination sensor 32a that detects inclination information on the measurement object in a state in which the measurement object performs constant velocity motion as constant velocity inclination information; a constant velocity motion determination unit 33a that determines whether the measurement object performs the constant velocity motion; and a control unit 35a that, when it is determined by the constant velocity motion determination unit 33a, determines that the measurement object performs the constant velocity motion, detects the inclination information on the measurement object on the basis of the constant velocity information and the inclination variation information created by the inclination variation information creation unit.SELECTED DRAWING: Figure 14
