摘要
The present invention provides a precise calibration method of a posture measurement system. According to an embodiment of the present invention, a method of accurately calibrating an attitude measuring system includes calibrating a non-orthogonal angle, a scale factor and a zero deviation between accelerometer axes of the attitude measuring system via an ellipsoidal fitting model (S1 ); Compensating (S2) the original data of the accelerometer using the calculated ellipsoidal parameters; (S3) correcting the electronic compass through the ellipsoidal fitting model according to the compensated accelerometer data; Compensating the original electronic compass data by the calculated ellipsoidal parameters (S4); And calculating (S5) an attitude according to the compensated accelerometer data and the compensated electronic compass data; , And this method can have reliable correction results and high accuracy with less correction consumption time.
