The method according to the present invention includes a step of dividing a golfer's golf swing into three golf swing trajectories, namely a backswing, downswing, and follow through, and allocating each golf swing trajectory to a 2D coordinate system formed by a horizontal axis and a vertical axis with a given point among the golf swing trajectories as the origin; a step of establishing, for each of the three golf swing trajectories, a line connecting the origin and a point selected in the golf swing trajectory and calculating an angle enclosed between each established line and the horizontal axis; and a step of calculating an angular difference between any two angles among the calculated angles, plotting the angular difference on a 2D map, and classifying the golf swing.
