PROBLEM TO BE SOLVED: To provide a posture angle detecting device which can be widely used by relaxing limitations on use location and use environments. SOLUTION: A posture angle detecting device is constituted of gyros 12a, 12b, and 12c to detect angular velocities about three axes which intersect one another at right angles, a motion angle computing device 18 to compute a movement angle corresponding to an angular velocity detected by each gyro, acceleration sensors 23a and 23b to detect biaxial acceleration, two geomagnetic sensors 22a and 22b, a stationary angle computing device 24 to compute a stationary angle about the three axes, a determining device 32 to determine and compute and whether the computation result of the stationary angle computing device 24 is false or not, a correction coefficient selecting device 33 to select the correction coefficient of the stationary angle computing device 24, a motion angle computing device 18 to compute a movement angle corresponding to the computation result of the determining device 32, and a posture angle computing device 42 to compute an output posture angle from the computation result of the stationary angle computing device 24 and the selection result of the correction coefficient selecting device 33. |
