Title:
CONTROL DEVICE, MEASUREMENT DEVICE, BALL, MEASUREMENT SYSTEM, CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/155686
Kind Code:
A1
Abstract:
This control device for a measurement device comprising an acceleration sensor and gyro sensor comprises: a first determination unit for identifying a stationary state of a measurement device on the basis of acceleration detected by the acceleration sensor; a second determination unit for determining whether the stationary state of the measurement device is stable on the basis of the acceleration detected by the acceleration sensor; a third determination unit for determining whether the measurement device is in a non-rotating state on the basis of angular velocity detected by the gyro sensor; an extraction unit for extracting, from acceleration data continuously measured by the acceleration sensor, acceleration when the measurement device was determined to be in a stationary state, the stationary state was determined to be stable, and the measurement device was determined to be in a non-rotating state; and an output unit for outputting the acceleration extracted by the extraction unit as correction data for the acceleration sensor.
