Abstract
A magnetic ball calibration method and a magnetic ball calibration apparatus is disclosed. The method includes: rotating a magnetic ball around a first axis and a second axis, and acquiring detection data of three-axis magnetic field components at a detection position during rotation; obtaining a calibration position of the magnetic ball according to the detection data; and calibrating the magnetic ball according to the calibration position. 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; the three-axis magnetic field components include an X-axis magnetic field component, a Y-axis magnetic field component and a Z-axis magnetic field component; the direction of the Z-axis magnetic field component and the Y-axis magnetic field component coincide with the direction of the second axis and the first axis, respectively.
