Title:
移動体の方位角補正装置及び方法
Document Type and Number:
Japanese Patent JP4203463
Kind Code:
B2
Abstract:
Provided are an apparatus and method of calibrating azimuth of a mobile device. The apparatus includes: a motor; a magnetic field measuring unit disposed in the mobile device and measuring magnetic field data indicating magnitudes of a magnetic field in different directions while being rotated by the motor; and a controller driving the motor, 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.
