摘要:A method and system for a non-intrusive parallel surface calibration for
gyroscopes in a mobile device are described. In a mobile device having a gyroscope,multiple rotation matrices can be determined bad on readings from the gyroscope.Each of the rotation matrices corresponds to a chain of rotations that occur when the

mobile device is picked up from a surface and later placed down on any substantially parallel surface. In some instances, three or more rotation matrices can be determined. Calibration parameters can be computed from the rotation matrices and can be ud to adjust subquent readings from the gyroscope. An eigenvector can be determined for each of the rotation matrices and tho eigenvectors can be ud to obtain the calibration parameters through an optimization process. The gyroscope calibration can be triggered by a change in the temperature of the mobile device.
