APPARATUS AND METHOD FOR MEASURING SLOPE

摘要

PURPOSE: A tiltmeter and a method for measuring the slope are provided to has a portable terminal, thereby measuring the slope of a surface conveniently. CONSTITUTION: An acceleration sensor(11) measures an acceleration value about three force axis meeting at right angle. A filter(12) filters the acceleration value. A filter controller(13) controls the number of the inputted acceleration values based on the inputted acceleration value and the filtered acceleration value. A controller(14) calculates the oblique direction or the angle of inclination based on the filtered acceleration value. A display unit(15) indicates the oblique direction or the angle of inclination.
