摘要： An azimuth measuring device capable of calibrating a magnetic sensor without putting load on a user is provided. When a point having amplified output values Sx, Sy, Sz after a sensitivity correction as x, y, z components is arranged on an xyz coordinate system, an offset information calculation section 8 calculates the center coordinates of such a sphere whose surface is located in the vicinity of each point and calculates an x component of the center coordinates of this sphere as a current offset Cx of an x-axis Hall element HEx, a y component of the center coordinates of this sphere as a current offset Cy of a y-axis Hall element HEy and a z component of the center coordinates of this sphere as a current offset Cz of a z-axis Hall element HEz. It is thereby possible to calibrate the magnetic sensor without putting load on the user.

摘要： An azimuth measuring device which can obtain offset information corresponding to one in the case where the direction of the azimuth measuring device is arbitrarily changed, without obtaining erroneous offset information when changing the direction of the azimuth measuring device while retaining its attitude with respect to a specific direction, is provided. A data processing section 19 processes data from a triaxial sensor which detects earth magnetism. In the data processing section 19, triaxial output data at the time when the direction of earth magnetism changes in a three dimensional space are repeatedly obtained not smaller than a predetermined number of times; the coordinates of a point where the variation of distances from a group of triaxial output data is minimum in a three dimensional coordinate which triaxial output data are related to respective axial components is estimated by using a statistical method, and is set as a reference point; offset information is calculated based on the coordinates of the reference point, and it is determined whether the group of triaxial output data is distributed in the vicinity of a specific plane; and when it has been determined that the group of triaxial output data is distributed in the vicinity of the specific plane, the coordinates of a reference point are not estimated, or the coordinates of an estimated reference point is deleted.
