Method and devices for temperature-based determination of gyroscope bias |
摘要 |
In one aspect, the present disclosure provides a processor-implemented method of determining a bias for an axis of a gyroscope. The method includes: obtaining a temperature reading; maintaining a plurality of bias estimators for the axis, each bias estimator associated with a temperature and configured to estimate a bias at the associated temperature, the plurality of bias estimators including a number of short term bias estimators for estimating biases for recently obtained temperatures and a number of long term bias estimators for estimating biases for temperatures obtained over a comparatively longer period of time; and determining a bias for the axis of the gyroscope based on the temperature reading and one or more of the bias estimators. |
