SLOPE MEASUREMENT METHOD AND APPARATUS USING TRIAXIAL TERRESTRIAL MAGNATISM SENSOR

摘要

PURPOSE: A slope measuring method and device by means of a triaxial terrestrial magnetism sensor are provided to check the location of a route display terminal in a complex road section. CONSTITUTION: A slope measuring method and device by means of a triaxial terrestrial magnetism sensor(101) comprises a slope measuring part(102). The triaxial terrestrial magnetism sensor measures Y-axis value, X-axis value and Z-axis value. The Y-axis value is the value of the progressive direction of a route display terminal(100). The X-axis value is the value of the vertical direction to the progressive direction of the route display terminal The Z-axis value is the value showing the height of the magnetic north direction. The slope measuring part measures the slope of the route display terminal based on the change amount of the X-axis value, the Y-axis value and the Z-axis value.
