The present disclosure relates to a golf instruction method and system, and more specifically, to a method for efficiently and systematically coaching the swing of a golf trainee from the perspective of teaching golf.
Golf, previously known as an aristocratic sport, is expanding into a popular sport in Korea. According to one survey, the number of golfers in Korea was 5.64 million as of 2021, surpassing Japan's 5.6 million.
As the demand for golf increases, the golf market size has also become a fairly large market, reaching KRW 6.9599 trillion (excluding caddie fees) as of 2021.
In popularizing golf, numerous new golfers, aspiring professional golfers, and professional teachers (lesson professionals) who teach them played a significant role.
In most cases, they go through a beginner's course in golf by receiving coaching on golf basics and swing from professional teachers for several months at an indoor practice range, screen practice range, or indoor practice range, and then going out to the actual field and playing golf games.
However, since the teaching methods of each professional teachers are different and the physical structure and level of practice of each golfer receiving lessons are different, there is a lack of a unified teaching method or integrated education system for systematic golf instruction.
Therefore, in this disclosure, a golf teaching method that can be applied to golf lessons by most professional teachers is disclosed.
The present disclosure is intended to solve the problems of the above-mentioned prior art, and discloses an efficient and systematic teaching method for golf.
One embodiment of the present invention relates to a method for performing golf lessons on a server, the method including: a first step of receiving information on the gender, age, and body type of the golfer and setting a lesson goal for the golfer; a second step of analyzing the golfer's swing motion obtained from the server and analyzing the club face control and lever system of the golfer; a third step of analyzing the path control of the club according to the golfer's swing; a fourth step of analyzing the control accuracy of the impact of hitting a golf ball and the flight of the golf ball; a fifth step of analyzing the consistency between the golfer's golf swing and the flight of the golf ball resulting therefrom over a plurality of times; a sixth step of analyzing the head speed of the club and the speed of the golf ball; and a seventh step of determining whether the golfer has achieved the set lesson goal.
In addition, the server analyzes the consistency between the golf swing and the flight of the golf ball accordingly, and if it determines that the predetermined condition is not satisfied, it moves to the third step of analyzing the path control of the club.
In addition, the server analyzes the club head speed and the golf ball speed, and if it determines that they do not meet the predetermined condition, it moves to the second step of analyzing the club face control and lever system and performs re-learning.
In addition, the server determines whether the golfer's set lesson goal has been achieved, and if it is determined that the lesson goal has been achieved, sets a lesson goal higher than the previously set lesson goal.
In addition, the steps 1 to 7 are characterized in that each step includes sub-steps, and goals can be set for each sub-step.
Another embodiment of the present invention relates to a golf teaching system, which includes: a terminal for receiving information on a golfer's gender, age, and body type, and for capturing a swing motion of the golfer; and a server, wherein the server includes: a golf motion analysis unit for analyzing a club face control and lever system, a path control of a club according to a swing, control accuracy of an impact when hitting a golf ball and the flight of a golf ball, consistency between a plurality of golf swings of the golfer and the flight of the golf ball, a head speed of the club, and a speed of the golf ball; a goal achievement determination unit for receiving a lesson goal of the golfer and determining whether the lesson goal of the golfer has been achieved; and a teaching saving unit for saving the teaching information of the golfer and creating a database.
In addition, the goal achievement determination unit is characterized in that it analyzes the consistency between the golf swing and the flight of the golf ball accordingly, and if it determines that the consistency does not meet a predetermined condition, it is set to request the golfer's swing again to reanalyze the path control of the club.
In addition, the goal achievement determination unit is characterized in that, if it determines that the head speed of the club and the speed of the golf ball do not meet the predetermined condition by analyzing them, it is set to request the golfer's swing again to reanalyze the club face control and lever system.
In addition, the goal achievement determination unit is characterized in that it determines, in the server, whether the golfer's set lesson goal has been achieved, and, if it is determined that the lesson goal has been achieved, sets a higher lesson goal than a previously set lesson goal.
In addition, the goal achievement determination unit is characterized by setting sub-goals for each of the club face control and lever system, club path control according to swing, control accuracy of impact when hitting a golf ball and flight of the golf ball, consistency between a plurality of golf swings of the golfer and the flight of the golf ball, club head speed, and golf ball speed, and determining whether the set sub-goals have been achieved.
The present disclosure relates to a golf teaching method and system, and can provide an efficient and systematic teaching method for golf.
In addition, as a golfer, you can continuously receive feedback on your swing posture, and set sub-goals for each stage to check whether the goal has been achieved.
In addition, as a professional teacher, by adopting the systematic instruction method of the present invention, you can integrate the teaching methods of each professional teacher, thereby maintaining consistency in instruction among professional teachers.
In addition, instead of the professional teacher visually checking the golfer's movements, the movement of the golf club, and the flight of the golf ball, you can analyze the error from the guideline through images captured through a terminal and a golf ball tracking radar, etc., thereby correcting the posture and golf club control, thereby providing objective feedback to the golfer.

In the present invention, “club” refers to a golf club handled by a golfer, for example, a golf club such as a driver, wood, hybrid/utility, iron, wedge, and putter.
In the present invention, “swing” refers to a series of processes for hitting a golf ball using a golf club. A swing refers to a series of movements such as address, take away, back swing, down swing, impact, and finish being performed continuously.
A golf teaching method according to an embodiment of the present invention is performed by capturing a golfer's swing motion, a golf club's movement, and a golf ball's flight at a terminal (200), transmitting the images to a server (100) connected to the terminal (200) via a network, and analyzing the golfer's swing motion and the golf ball's flight at the server (100) to provide feedback.
A server (100) according to an embodiment of the present invention analyzes the training information of a golfer and executes a program designed as an algorithm to improve the golfer's golf skills.
A terminal (200) according to an embodiment of the present invention receives information about a golfer (e.g., gender, age, body type) and captures the golfer's swing motion, the movement of a golf club, and the flight of a golf ball. A terminal (200) according to an embodiment of the present invention includes a camera sensor and a radar, and captures the golfer's swing motion, the movement of a golf club, and the flight of a golf ball and transmits the photographs to the server (100).
In addition, the terminal (200) according to an embodiment of the present invention can receive information identifying the golfer and determine who the golfer is to be image-captured.
The teaching system according to an embodiment of the present invention may further include a user terminal (300), and the user terminal (300) may be a device that displays feedback information on the golfer's learning.
The user terminal (300) according to an embodiment of the present invention may display a swing image captured by the terminal (200) so that the golfer can check it, or display content analyzed by the server (100) so that the golfer can check it.
The user terminal (300) according to an embodiment of the present invention may be a terminal that allows a golfer or a professional teacher to set a lesson goal or check a teaching history, and for example, a smartphone, an AI phone, a tablet, a laptop, a desktop, a MAC, etc. may correspond to the user terminal (300).
As shown in
First, the golfer can set the goal of the lesson before taking the golf lessons (S110). The server can set the level of goal achievement according to the golfer's lesson goal.
After that, the server analyzes the acquired swing motion of the golfer to analyze the golfer's club face control and lever system (S120). At this time, if the server determines that the goal is not achieved in this process, it can receive information on resetting the golfer's lesson goal (S110).
After that, the server analyzes the path control of the club according to the golfer's swing (S130). At this time, if the server determines that the goal is not achieved in this process, it can receive reanalysis (S120) information on the golfer's club face control and lever system.
After that, the server analyzes the control accuracy of the impact hitting the golf ball and the flight of the golf ball (S140). At this time, if the server determines that the goal is not achieved in this process, it can receive reanalysis (S130) information on the path control of the club according to the golfer's swing.
After that, the server analyzes the consistency between the golfer's swing and the flight of the golf ball according to the swing for a plurality of times (S150). At this time, if the server determines that the goal is not achieved in this process, it can receive reanalysis (S130) information on the path control of the club according to the golfer's swing.
After that, the server measures efficiency (S160). According to an embodiment of the present invention, the server analyzes the smash factor (the head speed of the club and the speed of the golf ball) as an example for measuring efficiency. At this time, if the server determines that the goal is not achieved in this process, it can receive reanalysis (S120) information on the golfer's club face control and lever system.
Afterwards, the server determines whether the previously set goal (S110) has been achieved (S170). If it is determined that the goal has been achieved, the golfer's lesson goal can be adjusted upwards so that the golfer can perform a teaching course with a higher difficulty level. Conversely, if it is determined that the goal has not been achieved, the golfer's lesson goal can be adjusted downwards so that the golfer can perform a taking course with a lower difficulty level or the same difficulty level.
By continuously performing the above series of processes, the golfer can receive continuous feedback and objective analysis information on the swing motion, which has the advantageous effect of improving golf skills.
As shown in
First, the first stage of goal setting and the seventh stage of the goal achievement determining stage are a kind of mind (Brain-Eye) stage, which is a stage for setting a goal that the golfer wants to achieve through the teaching process. For example, as an amateur golfer who hits a tee shot from a white tee, a goal of becoming a bogey player (total of 90 strokes) and the impact control required for the goal can be set.
The second stage of club face control and lever system and the sixth stage of analyzing the club head speed and golf ball speed are a kind of hand and arm training stage, which is a practice stage for grip movement of holding the club, lever system, etc.
After that, the third stage of club path control and the fifth stage of consistency between golfers' golf swings are the golfer's body stage, which constitutes one stage following the mind stage and the hand and arm training stage.
Finally, the fourth stage of the impact control accuracy is a stage that constitutes a turning point of the above stages, and is a stage that occurs when each level continuously gives and receives feedback on posture correction.
The first to fourth stages are stages that can be mutually repeated or returned to each other, and the fourth to seventh stages are organically connected as a process of moving to a designated stage. Each stage will be described in more detail below.
As shown in
The first step of goal setting according to an embodiment of the present invention is a mind level, and is a step of practicing basic knowledge such as understanding of basic swing movements, movement according to trajectory, understanding of impact, posture setup, and address.
Lesson goals for skill can be set based on various criteria. Tee shot locations such as red tee (ladies tee), white tee, etc., indicating the distance to tee off, can be set based on criteria such as bogey player (90 strokes), 10 handicap (HCP), 5 handicap, etc., indicating the number of strokes. Or, professional levels such as amateur, tour pro (PGA), etc. can be set as one goal.
As a sub-level of the first level, if the goal is set to level 1-1 red tee amateur (bogey player), and then achieved, the next goal can be level 1-2 red tee amateur (10 handicap).
The server can set each sub-level to be progressively higher (step by step), but in some cases, depending on the golfer's lesson results, some steps can be omitted and set to a higher level.
As shown in
In addition, as a lever system, the server analyzes the posture in which the connection of the three parts of the golfer's club swing, namely the wrist, elbow, and shoulder, forms one lever.
In addition, the server can analyze the hinge motion in which the golfer's hands are clasped together and the fingers are bent toward the back of each hand, and the coking posture in which the thumbs are bent upward when the hands are clasped together.
In addition, the server can analyze the pivoting motion, which indicates the change in direction of the club, and the lagging motion, which causes the club head to follow the downswing.
The analysis of the golfer's motion can be performed by comparing and analyzing the error between the guidelines set for the server and the golfer's motion, and the server can determine that the practice is sufficient if the error is smaller.
In the second stage, various sub-level goals can be set. For example, the goals can be set as sub-levels such as understanding the trajectory (level 2-1), club face control (level 2-3), and rotation axis control (level 2-9) with the easiest difficulty.
In the present invention, the sub-levels of the process of steps 1 to 7 can be set as different goals, and for example, if the sub-level of step 1-2 is set in step 1 (mind), it is not necessarily set as the sub-level of step 2-2 in the second stage, but can be set as a different sub-level depending on the golfer's practice results.
As shown in
As shown in
The golfer can set various sub-stage goals, such as 79 mph (stage 4-1) for the driver club speed, 92 mph (stage 4-5), etc., and the server can determine whether these goals are achieved.
Stages 1 to 4 above are meaningful as the creation stage of the motion to hit and send the golf ball, and stages 4 to 7 through impact have the meaning of maintaining the created motion.
As shown in
A golfer swings a plurality of times during practice, and a server according to an embodiment of the present invention analyzes the consistency (whether or not it matches) between the ball height, distance, direction, and trajectory of each swing as an evaluation index.
For example, a server according to an embodiment of the present invention can analyze whether the club path is consistent between a plurality of swings (step 5-3) or whether the launch angle is consistent (step 5-6).
As shown in
The server according to an embodiment of the present invention can calculate a variable called a smash factor by analyzing the head speed information of the club and the speed of the golf ball.
The smash factor in the present invention can be calculated as shown in the following mathematical expression 1.
Smash Factor=Ball Speed/Head Speed [Expression 1]
Smash factor refers to the correlation between head speed and ball speed. Head speed and ball speed are important factors in determining distance, and are numerical values that indicate whether head speed properly transmits power to the ball. In other words, it can be interpreted that the higher the smash factor, the longer the distance of the golf ball.
For example, a server can set the smash factor of a driver to 1.44 (step 6-2) and then adjust it upward to 1.49 (step 6-8) if this condition is met.
A server according to an embodiment of the present invention can determine whether each goal has been achieved as a result of the golfer's practice according to the instruction in steps 1 to 6. This can be set by determining whether a lower-level goal set in advance by the server has been achieved, and setting a new upwardly adjusted goal to perform steps 1 to 7 again.
A golfer can improve his/her skills by continuously setting upwardly adjusted goals and achieving them, and as a professional teacher, he/she can perform efficient and systematic instruction by coaching based on objective data.
As described in
