通过磁力计校准陀螺仪

Gyroscope Calibration via Magnetometer

Yuanxin Wu, Ling Pei

摘要:

磁力计、陀螺仪和加速度计是各种应用中常用的传感器。提出了一种利用磁强计在均匀磁场中标定陀螺的新方法。结果表明,在足够的旋转激励下,均匀磁场矢量可以被用来作为校准低成本陀螺仪的一个很好的参考。标定参数包括陀螺仪的比例因子、非正交系数和三轴偏置,以及陀螺仪与磁强计坐标系的失调。仿真和现场试验结果验证了该方法的有效性。

英文摘要:

Magnetometers, gyroscopes and accelerometers are commonly used sensors in a variety of applications. The paper proposes a novel gyroscope calibration method in the homogeneous magnetic field by the help of magnetometer. It is shown that, with sufficient rotation excitation, the homogeneous magnetic field vector can be exploited to serve as a good reference for calibrating low-cost gyroscopes. The calibration parameters include the gyroscope scale factor, non-orthogonal coefficient and bias for three axes, as well as its misalignment to the magnetometer frame. Simulation and field test results demonstrate the method's effectiveness.
