BIAS ESTIMATING METHOD, POSTURE ESTIMATING METHOD, BIAS ESTIMATING DEVICE, AND POSTURE ESTIMATING DEVICE |
摘要 |
A bias estimating method includes: calculating a virtual posture angle which is a posture angle with a bias which is assumed to be zero by the use of detection values of a plurality of axes in a calibration posture where one axis of a multi-axis acceleration sensor is parallel to the vertical direction; and estimating a bias value contained in the detection value of the axis using the detection value of the axis and the virtual posture angle.
