DEVICE FOR IDENTIFYING CHANGE IN VERTICAL DIRECTION BY USING AIR PRESSURE MEASUREMENT VALUE

摘要

An identifying device includes a vertical direction speed calculation unit configured to calculate a speed in a vertical direction of an air pressure measurement unit from an air pressure value measured by the air pressure measurement unit, the vertical direction speed determination unit configured to determine a magnitude of the speed in the vertical direction, a vertical direction continuous distance calculation unit configured to calculate a continuous distance of movement in the vertical direction based on the speed in the vertical direction calculated by the vertical direction speed calculation unit and the determination result of the vertical direction speed determination unit, and a vertical direction movement determination unit configured to determining whether the air pressure measurement unit is moving in the vertical direction or not in accordance with whether or not the vertical direction continuous distance is more than a predetermined threshold value.
