Abstract
The present application discloses a magnetic ball calibration method and a magnetic ball calibration apparatus. The method includes: rotating a magnetic ball around a first axis by a first angle, obtaining detection data during rotation, obtaining a zero point position P0 with a magnetic field intensity component in the direction of a second axis being zero; obtaining a calibration position of the magnetic ball according to the detection data and the zero point position P0; and calibrating the magnetic ball according to the calibration position of the magnetic ball; where when the magnetic ball is located at the calibration position, the magnetic polarization direction of the magnetic ball coincides with the second axis; the first axis is perpendicular to the second axis. By means of the magnetic ball calibration method and the magnetic ball calibration apparatus, the magnetic ball can be calibrated conveniently, quickly and accurately.
