Abstract
An object of the present invention is to provide a golf club classification method capable of classifying a golf swing precisely. Specifically, the present invention provides a classification method comprising steps of: partitioning the golf swing of the golfer into golf swing trajectories of a back swing, a down swing, and a follow through so as to determine a stable point in the golf swing trajectories as an origin for any two of the trajectories and to assign a two dimensional coordinate to the two golf swing trajectories; determining straight lines connecting each of one point selected within each of the two golf swing trajectories and the origin; calculating angles between each of the determined straight lines and the horizontal line respectively for the two golf swing trajectories; and classifying the golf swing based on a difference between the calculated angles.
