发明名称 Apparatus and method of calibrating azimuth of mobile device
摘要 Provided are an apparatus and method of calibrating azimuth of a mobile device. The apparatus includes: a magnetic field measuring unit having a plurality of magnetic sensors aligned in a constant angle interval on the mobile device and measuring magnetic field data indicating magnitudes of a magnetic field in different directions; and a controller generating a calibration table indicating a correspondence between an actual magnetic field trajectory formed by the magnetic field data and a theoretical magnetic field trajectory and calibrating azimuth of the mobile device using the calibration table.
