Abstract

Based on the analysis of Hard- and Soft- Iron effects of magnetometer’s errors, a tilted ellipse model for two-dimensional plane was formulated. According to the analytic geometry theory, a magnetometer calibration algorithm was proposed to calibrate the tilted ellipse into a standard circle by translation, rotation and scaling three steps, achieving the aim of magnetometer calibration. The experimental results show that the proposed algorithm calibrated the tilted ellipse approximately to a standard circle which had eliminated the combined Hard- and Soft- Iron effects successfully.
