Original Abstract Submitted
This invention can acquire a difference in motion of a motion acquisition target object without detecting the difference from the outside of the motion acquisition target object. A motion acquisition device includes two acceleration sensors, one angular velocity sensor, an information acquisition unit, and a motion analysis unit. The two acceleration sensors and the one angular velocity sensor are arranged in the motion acquisition target object rotated around a rotation axis. The information acquisition unit acquires acceleration information detected by the two acceleration sensors and angular velocity information detected by the one angular velocity sensor. Based on the acceleration information and the angular velocity information acquired by the information acquisition unit, the motion analysis unit estimates a distance from the motion acquisition target object to the rotation axis and an attitude angle of the motion acquisition target object.
