ZIKMUND, A. and P. RIPKA. Calibration of the 3D Coil System's Orthogonality. IEEE Transactions on Magnetics. 2013, 49(1), 66-68. ISSN 0018-9464. DOI 10.1109/TMAG.2012.2218583.
Two methods were tested for calibration procedures of the 3D coil system which is used as a source part of the magnetic tracker. Precise magnetometer’s positions with respect to the coil system were used for determining of the non-orthogonality of the coil system as well as for determining of the magnetic moment. The needed number of the reference positions was measured to calculate six unknown calibrated parameters. In comparison, the 3D coils system was also calibrated with a method which employs the orthogonal homogenous AC field generated in Helmholtz coils. The misalignment of up to two degrees was discovered.
