Novel Calibration Method for Magnetic Source in Magnetic Tracking System

摘要：

　　Magnetic tracking technology using tri-axial magnetic source is widely used in medical positioning and tracking equipment.Calibration of the system prior to the measurement is required in order to achieve better accuracy.In normal circumstances, optical positioning system is used to calibrate the magnetic positioning system.In this paper, a new calibration method of magnetic system is presented by using magnetic field and micro-motion platform.It is possible to solve the sight constraints of the optical system.The simulation result shows that this method has high calibration accuracy.
