CALIBRATING SENSOR MEASUREMENTS ON MOBILE DEVICES |
摘要 |
A device coupled with a magnetometer and an angular rate sensor can determine a heading of the device using magnetometer data. When the device receives a notification that the magnetometer data may be inaccurate, the device can determine the heading of the device using angular rate data. When the device determines that the magnetometer data are accurate, the device can resume determining the heading of the device using the magnetometer data. |
