    • An angular velocity detected by an angular velocity sensor (10) is integrated by a small angle matrix calculator (12) and a matrix adding calculator (14), and then restored as a posture angle (angular velocity posture angle) by a matrix posture angle calculator (16). A posture matrix is calculated by a tilt angle calculator (22) and an acceleration matrix calculator (24) and an acceleration detected by an acceleration sensor (20) is restored as a posture angle (acceleration posture angle) by a matrix posture angle calculator (26). Low pass filters (18, 28) each extract a low range component, the difference between the two is calculated by a differencer (30), and only the drift amount is extracted. A subtracter (32) removes the drift amount from the angular velocity posture angle and the result is output from an output device (34). In addition, a posture angle matrix calculator (36) converts the result to a posture matrix, which it feeds back to the matrix adding calculator (14).
    • 由角速度传感器(10)检测的角速度由小角度矩阵计算器(12)和矩阵加法运算器(14)积分,然后以姿势角(角速度姿态角)恢复矩阵姿态角 计算器(16)。 由倾斜角计算器(22)和加速度矩阵运算器(24)计算姿势矩阵,并且由矩阵姿态角计算器(20)将加速度传感器(20)检测出的加速度恢复为姿势角(加速姿势角) 26)。 低通滤波器(18,28)各自提取低范围分量,两者之间的差异由差分器(30)计算,并且仅提取漂移量。 减法器(32)从角速度姿态角度去除漂移量,结果从输出装置(34)输出。 此外,姿势角矩阵计算器(36)将结果转换成姿势矩阵,其将其反馈到矩阵添加计算器(14)。
