发明名称 SYSTEM AND METHOD FOR CALIBRATING A MAGNETOMETER ACCORDING TO DEVICE STATES
摘要 A method and system are provided for calibrating a magnetometer. The method comprises detecting a change in a physical configuration of the mobile device; applying at least one stored calibration parameter as a respective active calibration parameter when one or more stored calibration parameters corresponding to the detected physical configuration change are accessible by the mobile device; and performing a calibration to obtain at least one additional calibration parameter when the at least one additional calibration parameter is needed and applying the at least one additional calibration parameter as a respective active calibration parameter.
