20180003500 · 2018-01-04 ·

For triaxial magnetic detection data sequentially acquired as data points in a triaxial coordinate system, an offset calculation unit 30 calculates virtual data points P1′-P6′ by evenly parallel-translating each of data points P1-P7 so that a reference data point P7, for example, arbitrarily chosen from the data points P1-P7 coincides with an origin point O. A virtual offset point C′ for which the sum of the distances between the virtual data points P1′-P6′ and a curved surface H1 passing through the origin point O is minimized is then calculated. An offset value C for the magnetic detection data is then calculated by parallel-translating the virtual offset point C′ so as to restore the parallel-translated portion.
