In establishing a database, professional golfers and lessons can be classified into male and female, and can be classified according to body type in detail. Since the swing of golf is influenced by different body types of each person, a database of various professional golfers according to the body shape is needed to supplement these variables. The shape of a professional golfer is classified into three types, average, above average, and below average, based on medical or historical standards. Of course, the number of categories can be arbitrarily changed.

Then, the body feature data and the body thickness data obtained from the body feature extractor 151 and the body thickness extractor 152 are converted into a database.

On the other hand, when a database of body shape and body characteristics for a professional golfer is constructed, the body shape and body characteristics of the lesson target are extracted through the same process based on the constructed database, and the information about the professional golfer is accessed Match with the subject. The information that matches the professional golfer includes the joint changes to the swing, the trajectory to the golf club, and the process of establishing the database of the swing of the professional golfer and the swing of the lesson.

In Module 1, the body type is classified, and when Module 1 is finished, Module 2 classifies the body characteristics. As an example, FIG. 6 shows the result of the lateral body type analysis of a professional golfer having a gender male in the module 1 (assuming that a person in the photograph is a professional golfer), and the body characteristic is extracted from the module 2, .

In the meantime, the present invention also includes a database construction according to the swing.

20 pieces of joint information are extracted from the body from the information transmitted from the body- The joint information that changes in real time during the swing process is essential for correcting the posture of the swing and improving the distance. The characteristics extracted from the swing process of the professional golfer are shown in [Table 1].

Extracted swing feature Analysis item Sheep shoulder Shoulder tilt Both feet, shoulder position Stance width Right arm position, left arm position Body - Sway Head position, hand position Upper body slope Sheep shoulder, pelvis position Rotation angle and rotation speed of shoulder and hip

The body joint information obtained from the body type sensor 11 is used for feature extraction of the analysis items in [Table 1]. (The number of analysis items of the previous frame and the analysis item of the current frame) from the address operation to the finishing operation to start the swing by calculating the features corresponding to the analysis item for each frame (the body sensor 11 is 30 frames per second) ) And inserts them into Class 1 of the constructed database. During the swing, the changing analytical items change with time. By repeating the swing of the professional golfer several times and adding the extracted data to the database, it is possible to compare the swing process of the professional golfers according to the user's body shape do. The analysis items extracted from the swing process are shown in FIG. 7 as a graph.

On the other hand, the golf lesson management server 2 can detect the golf club track or track the golf club head to form a database. Of course, this golf club trajectory detection and tracking of the golf club head may take place in the controller 15 based on the data transmitted from the body sensor 11.

In the golf club detection unit 211, the RGB image obtained from the body type sensor 11 is used, and the detection of the golf club uses the differential image technique of the image. The difference image technique is an algorithm used to detect motion that moves in real time using the difference between the current frame and the previous frame. An operation for three frames is performed in order to reduce the motion blurring phenomenon that occurs when the swing is photographed at a speed of 30 fps (30 frames per second) of the body sensor 11. [ We apply a difference image technique between neighboring frames and perform a closed operation by minimizing undesired segmentation by noise. The AND operation is performed on the result after the execution and the edge is extracted to obtain the result shown in FIG. Then, the edge information extracted as shown in FIG. 8 (d) is used to perform a Hough linear transformation algorithm and a straight line is detected in the image.

The golf club head tracking unit 212 uses straight line information of the golf club detected in the golf club detection process. The result of the detection of the golf club is as shown in FIG. 9 (a), and the method of tracking the golf club head is as follows. The coordinate values corresponding to both end points of the extracted straight line are stored and compared with the coordinates of the hand obtained from the body shape sensor 11. [ A point having a larger value is defined as a golf club head by calculating the Euclidean distance of two points and hand coordinates. The result of tracking the golf club head is shown in Fig. 9 (b). The result of the detection of the golf club is represented by a red straight line in the image, and the result of the tracking of the golf club is represented by the yellow circle in the golf club part. The trajectory of the golf club head calculates the Euclidean distance and angle between the coordinates of the tracked golf club head and the center of the body every frame during the swing operation. The trajectory of the golf club head also extracts the standardized trajectory through the swing process of the professional golfer as in the case of the joint change database for the swing.

When the detection of the golf club and the tracking of the golf club head are performed as described above, the information about the trajectory of the golf club head is additionally inserted through Table 1 and the swing process for each class of the database on the built- A database of body shape and swing for the golfer is established.

Based on the body figure information of the body, the class for the professional golfer is classified and the class according to the sex and the body shape of each professional golfer is generated. The generated class contains body shape information for the side and front to match with the user, and it can automatically match the suitable professional golfer according to the body shape of the user. In addition, the change of the body joint and the change of the trajectory of the golf club which can be obtained in the course of the swing to the class classified according to the body type of the professional golfer is normalized through several experiment processes, and the normalized data is additionally inserted into the class classified in the above . The completed database contains data on the physical condition of the professional golfer and the swing process. The lesson person can use a self-diagnostic golf system that can calibrate his / her posture while comparing the data of the pro golfer with his / her body shape and his / her swing.

The golf lesson management server 2 configured as described above is connected to a plurality of golf clubs based on a centralized management and control system and is registered by a procedure such as an account, And transmits the information registered in each server to the exercise field where the request is generated.

Normally, it is configured to be operated automatically. In general, it operates in an automated manner. It monitors and controls the information of the user, which is used in real time through a dedicated batting system of all exercise fields.

In addition, it is possible to monitor the new service, the contract relationship by each training field, and the operation status of the member (user) together, and a series of situations in which the service provided additionally from the central system is paid by a method such as micropayment, It can be monitored and managed by the control system.

The lesson participants can compare the swing of their own swing stored during the designated golf lesson time and the swing of the most stable and improved swing among the golf lessons received during the designated period to the personal, 3D model video or the designated professional golfer's swing Etc., and the corresponding image can be stored in the system of the first driving range and secondly through the member company database of the central company and the customer database.

The stored images are repeatedly watched for swing of the individual and swing of the 3D model for supporting the golf lesson through the membership and login procedure through the homepage where the formal service is performed through the Internet environment of the computer such as the smart phone or the smart pad The viewing angle also serves to monitor the front, side, and top. In addition, you can analyze the specific swing by using 3D model and lesson object simultaneously or overlay function, and you can analyze the specific swing by using tools provided ((1) horizontal, vertical, diagonal line drawing, (2) ), (5) color conversion, etc.) can be used for in-depth analysis of the swing, and it is possible to analyze the swing by overlaying the swing of the golfer's own designated golfer.

On the other hand, when applying for swing information of famous professional golfers both at home and abroad, where the system is serviced by using additional services, etc., the swing of the professional golfer is compared with the swing of the golfer, and the swing speed and balance are adjusted, Swing analysis can be performed to maintain the overall orbit.

As described above, the golf lesson management server 2 typically constitutes a data storage server in a stepwise double triple fashion. The golf lesson management server 2 mainly includes a server for performing data storage functions for managing various customers, such as videos of members and customers, ), A database server for professional golfer to store and operate a detailed step-by-step swing image and information stored in the server for real-time service, and a database server for member company and customer management for overall system operation and integrated management.

Hereinafter, a golf lesson management method of the present invention using the system configured as described above will be described.

10 is an overall flowchart of a golf lesson management method according to an embodiment of the present invention.

Referring to FIG. 10, first, body type data and swing data of a professional golfer are generated using a body type-specific swing analyzer 1 (S1).

The golf lesson management server 2 transmits the body type data including the male / female data, the age data, the height and the weight, (S2).

Meanwhile, the lesson target person uses the body type-specific swing analyzer 1 to generate body shape data and swing data of the lesson target person (S3). The body shape data and the swing data of the lesson target person are transmitted to the golf lesson management server 2. The golf lesson management server 2 compares the body shape data and the swing data of the golfer with the swing data (S5), the body shape data and the swing data of the same or similar professional golfer are extracted to match the optimum golfer to the lesson target person.

Specifically, when using the body-specific swing analyzer 1, the golfer is instructed to perform the operation under the conditions specified for the professional golfer and the lesson target. That is, by using the dedicated program of the body type-specific swing analyzer 1, the operation of the professional golfer and the lesson object under specified conditions is photographed.

The software configured in each device constituting the swing analyzer 1 for each body type has a plurality of cameras and programs for motion recognition. Specifically, the swing analyzer 1 according to the body type (the space where the designated condition of the lesson person can be taken and the various body characteristics of the lesson person are monitored through the plurality of cameras to acquire information) It is a system for selecting smart phones and smart pads. Basically, the smartphone and the smart pad used for analyzing the body shape of the lesson object are configured to transmit various related information based on the exclusive system of the exercise field to the swing analyzing device 1 according to the body type and receive the information.

In a special case, the golf course management server 2 can be connected to the central golf lesson management server 2 via an Internet connection, and the necessary information can be provided through mutual transfer of related data. In this case, a permission system that can be connected to the central golf lesson management server 2 through a separate user right and pre-registration is established and established.

The program configured on the body type swing analyzer (1), smart pad, and smart phone basically performs the camera function. In addition, the OSD (On Screen Display) function sets the guide line, Provide the guideline information that satisfies the condition continuously so that the lesson target person can take the action of the specified condition so that the condition action can be taken.

(Eg, name, age, gender, weight (other explanation), personal information, and taste information such as golf (sports)) are stored in advance, and then the swing analyzer 1) or a smart pad or the like. In the case of the designated system, the weight can be measured automatically through the foot plate (plate). If the measurement is made through other smart pads, etc., Record.

Through the specified condition operation, detailed information such as key, upper body and lower body ratio, arm length, leg length, length of each joint, flexibility, and other specific information of the lesson subject are analyzed and calculated. The swing analyzer 1 according to the body type, the smart pad, and the smart phone are configured to exchange mutual data through an associated WI-FI access point (AP). If necessary, the smart pad and the smart phone can directly access the golf lesson management server 2 via the Internet network through separate permission procedures and revisions, and exchange necessary information with each other.

As described above, when the user information is acquired from the professional golfer and the lesson target through the operation of the specified condition, the related information is transmitted to the central golf lesson management server 2 in accordance with the standard (transformed into the promised format) By comparing and analyzing the detailed information of the registered professional golfers, a professional golfer having about 80% similarity is selected as an example. In this case, when the number of designated golfers is insufficient in the designated number, the degree of similarity is lowered so that a specified number of professional golfers are selected. On the contrary, when the number of pro golfers selected by the degree of similarity is too large, the degree of similarity is increased so that a proper number of pro golfers are selected.

The above-described condition analyzes the body shape, flexibility, and characteristics of the lesson target person through the plurality of body-type sensors 11 and the camera 12, so that more reliable golf lesson matching can be performed.

When the operation of the lesson target designation condition is analyzed in the body type-specific swing analyzer 1, the smart pad, the smart phone, etc., the information is collected, stored and managed on the basis of the exclusive system of the exercise range and stored in the central golf lesson management server 2 , And the golf lesson management server 2 at the center selects appropriate professional golfers through the database of the registered professional golfers based on the information of the provided conditions.
