摘要:
A method and an apparatus is provided for processing data for calibration. The method comprising switching hardware into a pre-calibration mode and using the hardware to selectively pre-store measured data for calibration. In particular, the data for calibration is magnetic field data from a magnetometer, that may be used as a compass in a mobile electronic device. The selection of measurement data for pre-storage is based upon one or more criteria.
摘要:
A method and system are provided for calibrating a magnetometer on a mobile device. The method includes initiating a calibration of the magnetometer, determining an intermediate parameter associated with the calibration and when a characteristic indicative of a state of the mobile device is detected using the intermediate parameter, applying at least one stored calibration parameter associated with the state as an active calibration parameter.
