Abstract
A calibration scheme under spherical coordinates is described for a magnetic tracker used in VR (virtual reality) system. A look-up table containing data of tracked values for certain positions in the working space, specified in spherical coordinates, is generated first, which is then used to calibrate the tracking results by a two-dimensional interpolation. The scheme can effectively correct the static errors in the magnetic tracking system. The employment of spherical coordinates significantly reduces the calculation complexity in calibration.
