| Zusammenfassung: | A magnetic ball calibration method and a magnetic ball calibration apparatus. The magnetic ball calibration method comprises: a magnetic ball (10) rotating around a first axis (110) by a first angle, and obtaining detection data during rotation; according to the detection data, obtaining a zero point position P0 of the magnetic ball (10) with a magnetic field intensity component in the direction of a second axis (120) being zero; according to the detection data and the zero point position P0, obtaining a calibration position of the magnetic ball (10); and calibrating the magnetic ball according to the calibration position of the magnetic ball. When the magnetic ball (10) is located at the calibration position, the magnetic polarization direction of the magnetic ball (10) coincides with the second axis (120), and the first axis (110) is perpendicular to the second axis (120); a three-axis magnetic field component comprises an X-axis magnetic field component, a Y-axis magnetic field component, and a Z-axis magn |
