SWING ANALYSIS DEVICE, NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM STORING PROGRAM FOR ANALYZING SWING, AND SWING ANALYSIS SYSTEM

摘要

A swing analysis device for analyzing a swing of a ball hitting tool includes: an information input unit configured to receive input of acceleration information and angular velocity information detected by a sensor attached to the ball hitting tool; a posture calculation unit configured to calculate posture information of the ball hitting tool in the swing by applying a predetermined filter to the acceleration information and the angular velocity information; a correction unit configured to correct the posture information of the ball hitting tool in the swing based on the posture information of the ball hitting tool at a first time in the swing; and a swing information calculation unit configured to calculate a swing trajectory of the ball hitting tool based on the acceleration information and the posture information of the ball hitting tool corrected by the correction unit.
