Golf swing motion analysis method and system {GOLF SWING MOTION MONTORING METHOD AND SYSTEM}

The present invention relates to a method and apparatus for analyzing golf swing motion, and more particularly, to obtain body size information of a plurality of professional golfers, to generate a professional golfer character using the body size information, and then to golf swings of the professional golfers. Generates a swing motion by capturing motion, synthesizes the character and swing motion of the professional golfer, then produces a moving professional golfer animation, obtains body size information of a golf practitioner in the same way, and uses the body size information to play golf. After generating a trainee character, the golfer's golf swing motion is captured to generate a swing motion, the golf trainee's character and a swing motion are synthesized, and then a moving golfer animation is produced. Display the golf practitioner animation, the closest animation and body size information It is about selecting and displaying animations of professional golfers.

Golf, which used to be a symbol of wealth until the past few years, is now booming as a profession for youth, a hobby for middle-aged adults, and a social means, due to several professional golfers in Korea. . As a result, many hobbyists enjoy playing golf and are looking for a golf practice day and night in various parts of the city to go to the field.

However, the golf practice ranges that are being created now occupy a large area due to the characteristics of the golf movement despite the urban area of the city, and professional golfers or semi-professional golfers who receive high salaries are employed as instructors. You can only take golf lessons if you pay the lesson fee. It is also true that the high price of golf equipment still belongs to the class of extravagant sports.

As a result, the golf practice site wants to reduce the size of the golf practice site or make it near the city center to secure golf club members who want to enjoy golf at a low cost, and also pay expensive lesson fees paid to professional or semi professional golfers. I plan to get more hobbyists. As a way to attract a lot of golf lovers who require low-cost lessons, proposals have been made to reduce the cost of the instructor by reducing the role of the instructor and to use the golf practitioner's swing motion lessons in other ways. The motion lesson method is an analysis method using a video camera.

The conventional video camera analysis method for analyzing golf swing motion of a golf practitioner simply used a video camera and a monitor. For example, a video camera is installed around the golf practitioner, and the golf practitioner's golf swing motion is continuously recorded and connected to a monitor connected to the video camera to play a film photographed by himself and analyze the film by themselves. He records and relies on a professional golfer's advice.

The analysis method using the conventional video camera can evaluate the balance of the golf practitioner's body because it captures the overall golf swing motion of the golf practitioner, but it is difficult to realize the detailed screen and the motion of each step in the motion is shown in a slow screen. There is a lack of sharpness, so you have to analyze it as a still image or a playback image. On the other hand, there is a way to use expensive video when you want to accurately implement the clarity and slow screen of the video screen, but the expensive video is too expensive than the general video, it is practical to use expensive video. In addition, if the person wants to take a picture by themselves, too often trial and error until the desired image of the practitioner is reproduced on the monitor, and the inconvenience of having to adjust the position of the camera when changing the position of the golf practitioner. In addition, most of the practitioners are shooting their own swing motion with a camera. When playing the film, only the flat screen is displayed, and the evaluation is incorrect even if the evaluation is performed. Acquiring motion is not easy. This conventional video camera analysis method can be achieved only if the golf practitioner and professional golfer together to achieve a predetermined purpose, even if the purpose of the video camera is only a means of taking a picture of yourself and the analysis method It is irrelevant and it is difficult to expect to reduce the lesson fee because it must be carried out with a professional golfer.

In order to solve the above-mentioned problems, the present invention provides the steps of: A) generating a standard swing animation DB that stores body index information, swing motion, swing animation information, etc. of a professional golfer, B) body index information of a golf trainee, Generating a trainee swing animation DB for storing swing motion and swing animation information; and (C) a golfer's swing animation and a professional golfer having a body dimension closest to the body size of the golf trainee from the standard swing animation DB. By providing a step of comparing the swing animation of the golf practitioner is to provide a golf swing motion analysis method that can correct the golf swing motion by yourself without receiving a lesson of the professional golfer directly in the golf practice.

In addition, an object of the present invention is to provide a golf swing analysis system that can be compared to the golf swing motion by selecting a professional golfer similar in body size to the golf practitioner using the golf swing motion analysis method.

It includes an animation composition module, a standard swing animation DB that stores standard swing animations of professional golfers, a trainee swing animation DB that stores trainee swing animations, and an evaluation system that calls and displays trainee swing animations and standard swing animations. It is composed.

(A) generating a standard swing animation DB for storing the body index information, swing motion, swing animation information, etc. of each professional golfer is a small step of acquiring the body size information of a plurality of professional golfers, each of the professional A small step of capturing a golf swing motion of a golfer and a small step of generating a swing animation of each expert with reference to the body size information and the captured swing motion.

The small step of acquiring the body size information of the plurality of professional golfers is a process of obtaining data such as sex, height, weight, age, left / right and head, trunk, upper extremity, lower extremity, and the like offline. It is ideal to obtain the data online by measuring in real time.

Many of the professional golfers include world-famous athletes, and after inputting the body size information of the world-famous athletes offline to create a DB and produce an animation, it is very useful swing motion analysis method to compare with your golf swing Will be.

The left / right hit means left-handed / right-handed, and it is natural to distinguish between left-handed and right-handed because the swing motion of the left-handed / right-handed is different due to the characteristics of the golf motion.

The head, trunk, upper and lower limbs are divided into four major parts of the body, the head and neck, the trunk is from the shoulder to the waist, the upper and lower arms, the lower leg means the lower back. Golf exercise is a kind of central exercise, which is sensitive to the change in body weight and affects the distance of the ball and the direction of the ball according to the motion of the head, trunk, upper limb and lower limb. Obtaining body size information is an important part of practicing the present invention.

(B) generating a trainee swing animation DB for storing the trainee's body index information, swing motion, swing animation information, and the like, includes: a small step of acquiring body size information of a golf trainee; and a golf swing motion of the golf trainee Includes a small step to capture it.

Since the training swing animation DB generation step is similar to the standard swing animation DB, the embodiment will be described in more detail.

(C) comparing the swing animation of the golf practitioner and the swing animation of a professional golfer having a body size closest to the body size of the golf practitioner from the standard swing animation DB, in accordance with the object of the present invention, The golf swing golfer's swing motion and the professional golfer's swing animation are displayed in an integrated manner to evaluate and correct the golf swing golfer's golf swing motion.

The swing animation of the golf practitioner and the swing animation of the professional golfer may be overlapped and displayed, and the evaluation message may be displayed on the screen according to the overlap screen ratio. In other words, based on the swing animation of a professional golfer, the more overlapping parts of the golfer's swing animations are displayed, the wider the swing motion message, and the narrower the overlapping parts, the more corrective messages are displayed. .

The body size information input device of the golf swing analysis system includes corresponding data, that is, gender, height, weight, age, left / right and tofu, trunk, upper extremity, lower extremity number, tape measure, weight scale, and various sensors. As a device for receiving data and inputting data, if the measuring device can transmit an electrical signal, it can be directly inputted into a database online. Otherwise, it can be input by an input device such as a keyboard or a mouse.

The signal of the motion capture sensor that transmits the movement track signal of a professional golfer / golf practitioner of the golf swing analysis system is preferably a coordinate value and can transmit as a 2D value or a 3D value. As it can be displayed on the screen viewed from the realistic, it is possible to analyze a better golf swing motion.

The swing motion animation module of the golf swing analysis system is a module that forms a swing motion skeleton of an animation by mapping a movement trajectory signal of a professional golfer or a golf practitioner inputted from a motion capture sensor in a point-to-point manner. The number of points corresponds to the number of motion capture sensors and determines the contour of the swing motion skeleton according to the number of points. Thus, the number of points is the basis for generating more precise animation.

On the other hand, in the method of forming the swing motion skeleton, it would be natural that a more advanced technique can be used to generate the swing motion skeleton if there is an advanced technique than the method described herein.

The swing animation synthesis module for synthesizing the standard swing animation or the trainee swing animation may apply the character of the size in the body size information of the professional golfer or golf practitioner to the swing motion of the professional golfer or golf practitioner generated by the swing motion generation module. As a module, this module generates images. The animation by the synthesis module allows the professional golfer and the golf practitioner to generate a video so that the two animations can be compared, and in the case of 3D animation, swing motions of various angles can be displayed.
