Methods and devices for determining orientation

摘要

Methods and electronic devices for determining orientation are described. In one aspect, the present disclosure provides a processor-implemented method of determining a corrected orientation of a gyroscope on an electronic device. The method includes: obtaining a gyroscope reading; determining a first orientation estimate based on the gyroscope reading and a past corrected orientation; determining whether the gyroscope was saturated when the gyroscope reading was obtained; adjusting a saturation correction learning rate for the gyroscope based on the result of the determination of whether the gyroscope was saturated; and determining a corrected orientation based on the first orientation estimate, a second orientation estimate and the saturation correction learning rate.
