Abstract

A golf gear fitting system (2) includes a swing data acquisition unit (21) to acquire swing data from a sensor (11) installed in a golf club (1), a swing data storage unit (22) to store the swing data acquired by the swing data acquisition unit (21), a data classification unit (23) to classify the swing data stored in the swing data storage unit (22), and a data prediction unit (24) to predict swing data of specifications not measured by the sensor (11) by referring to the swing data classified in the data classification unit (23).

Description

TECHNICAL FIELD[0001]The present invention relates to a golf gear fitting system, a golf gear fitting method, a golf gear fitting program, a golf swing classification method, a golf shaft fitting system, a golf shaft fitting method, and a golf shaft fitting program.[0002]The present application is based upon and claims the benefit of priority to Japanese Application No. 2015-102548, filed May 20, 2015, the entire contents of which are incorporated herein by reference.BACKGROUND ART[0003]In 2008, a regulation on the repulsive force of a golf club head was put into effect by the Rules of Golf, making it difficult to optimize ball carry by the club head alone. In response to the regulation, manufacturers switched their focus to the shaft, aiming to increase ball carry by optimizing the bending of a shaft. Accordingly, variations in shafts increased as of 2012, and combinations of shafts and club heads thereby brought about a further increase in variations of golf clubs. As an undesirab...

AI Technical Summary

Benefits of technology

The present invention allows for easy determination of suitable golf gear through a few test hits. This is useful for golfers who have an unstable swing. Additionally, the reduced measurement time allows for more time to listen to the golfer and test hit the gear they plan to purchase.

Problems solved by technology

In 2008, a regulation on the repulsive force of a golf club head was put into effect by the Rules of Golf, making it difficult to optimize ball carry by the club head alone.

As an undesirable effect of such an increase, it is difficult for a player to select the most suitable golf gear, especially the most suitable shaft, at time of purchasing a golf club.

However, when such a technique is used, it is necessary for a player to test many golf clubs by actually hitting golf balls.

Therefore, the player can only make a better choice, but it is still hard to make the best choice.

Thus, when clubs and shafts with significantly different properties are simulated based on the data of one swing, the problem is that the simulation results do not correspond to actual solutions.

However, when the technique described in Patent Literature 3 is used, the issue is that it is difficult to simulate by changing, for example, the “weight” and “length” of members of a golf club.

That is because when the weight and length are changed, even with the same player, swing time is significantly different from address (the position when the golf club is in contact with the ground) to top (the position when the golf club is at the top of backswing) and from top to impact (the moment the head hits a ball), making it difficult to obtain sufficiently accurate computations.
