introduce the traditional two samples rotation vector algorithm and three samples rotation vector algorithm, which fit the incremental angular condition . but, the output of fiber optic gyro is angular rate of the vehicle, the error would increase serious if use traditional algorithm 由于光纤陀螺仪输出为角速率信号,而传统的旋转矢量算法输出为角增量信号,采用角增量提取算法,旋转矢量精度会大幅大降。
