摘要

[Problem] To provide a golf club swing analysis method, swing analysis system, and swing analysis program capable of easily calculating the positions of markers on a club head and analyzing a swing when the swing is analyzed from images taken with a single camera. [Solution] This swing analysis method is provided with: a step for preparing a golf club that has a head; a step for installing multiple markers on the head; a step for acquiring multiple basic head images by filming the head in multiple orientations with a single camera; a step for calculating, as basic marker position information, the position of each marker in a head coordinate system that uses the golf club head as a reference on the basis of the multiple basic head images; a step for acquiring a single analysis head image by filming a swing of the golf cub at a specified time using the camera; and a step for calculating the position and/or the orientation of the golf club head at the specified time in the object space from the positions of the multiple markers in the single analysis head image.
