Title:
MOTION ACQUISITION DEVICE, MOTION ACQUISITION METHOD, AND MOTION ACQUISITION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/100250
Kind Code:
A1
Abstract:
The present invention enables acquisition of variations in motion of an object of motion acquisition without detecting the object from outside thereof. This motion acquisition device comprises two acceleration sensors, one angular rate sensor, an information acquisition unit, and a movement analysis unit. The two acceleration sensors and the one angular rate sensor are disposed in an object of motion acquisition that is rotated around a rotational axis. The information acquisition unit acquires acceleration information detected by the two acceleration sensors and angular rate information detected by the one angular rate sensor. The movement analysis unit estimates the distance from the object of motion acquisition to the rotational axis and the attitude angle of the object of motion acquisition on the basis of the acceleration information and the angular rate information acquired by the information acquisition unit.
