摘 要：Accelerometer is a motion sensor,which can sense motion change in any of its three *** is known that accelerometers inevitably suffer from multiple noise effects,and hence a six-position calibration method is usually applied to estimate the deterministic sensor ***,for the traditional six-position calibration method,a high-precision turntable is needed,which is relatively expensive and fixed in place,and thus not available for many research groups and for use as a portable ***,this paper improves the traditional six-position method by introducing a rotation matrix to achieve the goal of a *** improved method can still maintain the effectiveness of accelerometer calibration without using any auxiliary *** paper proves the reliability of the improved six-position method through detailed derivation and comparative experiments.
