METHOD AND APPARATUS FOR MEASURING TILT USING A THREE-AXIS GEOMAGNETIC SENSOR

WIPO Patent Application WO/2010/005200

A2

The invention relates to a method and to an apparatus for measuring a tilt using a three-axis geomagnetic sensor. The apparatus for measuring a tilt using a three-axis geomagnetic sensor includes a three-axis geomagnetic sensor for measuring a value of a Y-axis which is the advancing direction of a path display terminal, a value of an X-axis which is vertical to the advancing direction of the path display terminal, and a value of a Z-axis direction which represents the height in the north direction indicated by a compass; and a tilt measuring unit for measuring the tilt of the path display terminal on the basis of the variation in the values of the X-axis, of the Y-axis, and of the Z-axis.
