ANALYSIS SYSTEM AND ANALYSIS METHOD

摘要

An object of the present invention is to enable accurate classification of golf swings. A data processing apparatus computes a state of motion of a golf ball on the basis of still images captured by an imaging unit. The data processing apparatus divides a golf swing identified by swing data acquired during a golf swing by a player into golf swing paths of a back swing, a down swing and a follow through, assigns a path in two-dimensional coordinates having a vertical axis and a horizontal axis to any two of these three golf swing paths, calculates an angle formed between the golf swing path and the horizontal axis, for each of the two golf swing paths, and classifies the golf swing on the basis of an angular difference between the respective angles thus calculated. The present invention can be applied to, for example, an analysis system for analyzing a golf swing.

主权项

1. An analysis system which analyzes a golf swing when a player strikes a golf ball with a golf club, comprising:
a head measurement apparatus which measures a head speed of the golf club when striking the golf ball; an imaging unit which captures still images used for computing a state of motion of the golf ball on the basis of the head speed measured by the head measurement apparatus; an acquisition apparatus which acquires swing data, which is data during a golf swing of the player; and a data processing apparatus which analyzes the golf swing on the basis of the swing data and also computes the state of motion of the golf ball on the basis of the still images captured by the imaging unit, wherein the data processing apparatus includes: a measurement unit which divides the golf swing identified by the swing data into golf swing paths of a back swing, a down swing and a follow through, and assigns a path in two-dimensional coordinates having a vertical axis and a horizontal axis, to any two golf swing paths among the back swing, the down swing and the follow through; a characteristic amount extraction unit which calculates an angle formed between the golf swing path and the horizontal axis, for each of the two golf swing paths; and a statistical processing unit which classifies the golf swing on the basis of an angular difference between the respective angles thus calculated.
