Title:
MOTION ACQUISITION APPARATUS, MOTION ACQUISITION METHOD, AND MOTION ACQUISITION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/100249
Kind Code:
A1
Abstract:
The present invention enables acquisition of variation in motion of an motion acquisition subject without detecting the motion acquisition subject from outside thereof. This motion acquisition apparatus comprises: two acceleration sensors; an information acquisition unit; and a kinematic analysis unit. The two acceleration sensors are disposed in a motion acquisition subject which is moved rotationally about a rotary shaft. The information acquisition unit acquires acceleration information detected by the two acceleration sensors. The kinematic analysis unit estimates the distance from one of the acceleration sensors to the rotary shaft and the attitude angle of the motion acquisition subject on the basis of the acceleration information acquired by the information acquisition unit.
