Title:
ANGLE MEASURING MODULE, POLE, ANGLE MEASURING METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/187035
Kind Code:
A1
Abstract:
An angle measuring module (20) includes: an acceleration sensor (21), the measuring axis of which is fixed to a shaft of a pole; and a control unit (25) that acquires a sensor output value. After a ground contact determining unit (252) of the control unit (25) determines that the output of the acceleration sensor (21) is an extreme value, an angle calculating unit (253) calculates the angle between the direction of the acceleration vector and the extension direction of the shaft when the magnitude of the acceleration vector becomes a value indicating the acceleration of gravity. Then, an angle determining unit (254) determines whether the measured angle is within a predetermined range, and a speaker (24) outputs a determination sound which is different depending on the determination result.
