Golf Swing Motion Analysis System {System for Analyzing Golf Swing Motion}

The present invention relates to a golf swing motion analysis system, and is applied to a screen golf system relates to a golf swing motion analysis system for acquiring the motion information of the golf ball and golf club to check the speed, distance and direction of the golf ball.

The cultural industry is often referred to as the highest value-added industry of the 21st century, or as a battleground for national competitiveness. Among the various cultural fields, sports is recognized as a cultural area with the greatest potential and much larger than other fields in size and interest. Sports has now grown rapidly in developed countries as an industry, and has a great growth potential to develop into a key industry in the 21st century.

One of the most popular sports these days is golf. The domestic golf population increased significantly in the late 1990s due to the government's popularization of golf and the entry of domestic professional golfers into overseas stages. Many professional golfers' LPGA activities and PGA activities changed the perception of golf and made the public interested in golf.

In addition, the introduction of a five-day workweek will increase the leisure time, increase the income level, and increase the base of the golf population. The awareness of golf has changed due to the exponential growth of 3 million golfers in Korea and the activity of professional golfers abroad, which has grown exponentially in just 20 years.

However, it still costs a lot to go out on the field, and the indoor golf practice has a problem that it is difficult to practice the swing suitable for the body during practice because it can not know exactly the distance and direction of the golf ball when hitting.

Recently, golf simulation technology using virtual reality has been developed and applied to overcome the spatial limitations of indoor golf practice grounds. This is to measure the dynamic data (Kinetic data) about the speed and flight angle of the golf ball in a certain space adjacent to the golf at bat, based on this to determine the ball trajectory of the golf ball and output it as a 3D image on the screen installed in front of the bat at bat .

At this time, the control unit for outputting the expected ballistics of the golf ball is input to the same image as the field of the actual golf course, so that the player can obtain a visual effect as if playing golf on the actual field. Such golf simulation systems are commonly referred to as 'screen golf'.

The most important technical factor in the system that implements the screen golf is to accurately predict the ball trajectory and the falling point of the golf ball. To do this, it is necessary to measure the dynamic information of the golf ball more diversely and accurately in a limited space.

Conventionally, various apparatuses for measuring dynamic information of a golf ball have been proposed. For example, US Patent Registration No. 6,302,802 (Registration Date; October 16, 2001), Korean Patent Registration No. 10-0734593 (Registration Date; 2007.06. 26.).
