| Abstract | This paper presents a novel calibration algorithm for digital compass in 3 dimensions. A spatial interpolation algorithm is used for better accuracy. At present, because of the problem that the electronic compass calibration method based on ellipsoid fitting is not accurate and the calibration method is complex under the special application conditions, we put forward a novel calibration method based on the interpolation algorithm. Firstly, according to the error model and the 12-position calibration method, 12 basic integrated error parameters can be calculated. Then, we study the interpolation method and design a high-precision interpolation algorithm. Finally, the experimental data show that in the case of plane, the maximum heading angle error within ± 0.2°. The interpolation method based on interpolation algorithm can obviously improve the accuracy of heading angle of electronic compass. © 2017 IEEE. |
