Abstract
The present disclosure provides a posture estimation method, a posture estimation apparatus, and a computer readable storage medium. Here, the posture estimation method includes: calculating an angular velocity control amount at a current moment based on a measured acceleration value and an estimated acceleration value at the current moment; correcting the measured angular velocity value at the current moment according to the calculated angular velocity control amount to obtain the corrected angular velocity value at the current moment; and obtaining an estimated posture quaternion value at a next moment according to the corrected angular velocity value obtained by calculation and an estimated posture quaternion value at the current moment.
