The present invention relates to a golf swing motion analysis system and method. More specifically, four or more video frames including an address, a back swing top, an impact, and a finish in an image frame of a golf swing motion recorded by a video photographing apparatus (hereinafter, referred to as " n " s), and outputting the frame to a standard operation.

Recognized as a high-class sport, golf is increasingly recognized as a popular sport, and it is recognized as a sport that helps a lot in physical and mental health. The golf game is based on the way the game is run. The golfer who has the lowest number of balls in the round or three rounds or four rounds in 18 holes is the winner. The accuracy here is largely determined by the golf swing posture, and accuracy and distance can be achieved only by correct striking in the right posture.

Therefore, in order to have a correct golf swing posture, golfers watch a golf game, observe professional golfers' attitude, or watch information on golf teaching programs provided through television. However, this method can not be directly compared with his / her swing posture, so its effect is limited. The best way is to get direct guidance from a professional in the field of golf practice, but it is very costly and inconvenient because you have to spend time with a professional or have to wait a lot of time to get a map.

To solve these problems, devices have been developed to record the swing posture of the practitioner during the practice of golf swing, or to provide a video recording of the professional golfer or the professional swing posture together with the swing posture of the practitioner.

1 is a view showing a schematic configuration of a golf simulator using a conventional moving picture.

1, the conventional golf driving simulator includes a camera 100, a key operation unit 110, a main control unit 120, a video recording device 130, a main screen and a sub screen An image input device 140, a money input device 150, and a golf ball supply device 160.

The swing motion of the practitioner is photographed through the camera 100 and the photographed practitioner's image is recorded on the video recording apparatus 130 under the control of the main control section 120 and is outputted to the main screen of the video output apparatus 140 .

On the other hand, if the practitioner inputs an operation command to the main control unit 120 through the key operation unit 110 in advance and selects a specific player and a swing type to be compared in advance, The swing motion of a specific player stored in the recording apparatus 130 is output as a comparison screen.

At this time, when the swing motion of the practitioner is displayed on the main screen for a certain time, the main screen is temporarily stopped and the swing motion of the specific player is displayed on the sub screen for a certain time. Thus, the swing motion of the practitioner and the swing motion of the specific player are sequentially displayed on the main screen and the sub-screen at regular intervals.

Such a conventional golf driving simulator helps the practitioner to have a correct swing posture by correcting his / her posture by comparing his / her swing motion with the swing motion of a specific athlete.

However, the conventional video golf simulator is limited in the following points.

First, there is a problem that the practitioner can not easily compare at a glance because the swing motion of the practitioner and the swing motion of the specific player are displayed at a predetermined time interval. In order to solve this problem, it is not easy to see the difference between the two swing motions in the continuous motion picture even if the swing motion of the practitioner and the swing motion of the specific player are simultaneously displayed on the main screen and the sub screen.

Second, there is a problem that the swing motion of the practitioner and the swing motion of a specific player are not displayed in synchronization with each other. In order to effectively compare the swing motion of a practitioner with the swing motion of a specific athlete, a correspondence relationship must be established between a specific swing motion and a swing motion of a specific athlete.

In order to solve such a problem, the present invention provides a golf swing golf club having four or more images including an address, a back swing top, an impact, and a finishing among video frames of a golf swing motion recorded by a camera (Hereinafter, referred to as " n ") image frames corresponding to a predetermined standard operation, and outputting the comparison result to a standard operation.

In order to achieve the above object, the present invention provides a golf swing golf club having a golf swing operation, comprising: an address, an address, a back swing top, an impact, A golf swing motion analyzing method for extracting n image frames corresponding to each of a predetermined standard motion of more than a predetermined number (hereinafter, referred to as 'n') of motion images to compare / analyze the golf swing motion with the standard motion, (a) extracting an image frame corresponding to the address, the backswing top, the impact, and the finish among image frames of the golf swing operation recorded by the image photographing apparatus; (b) dividing the entire swing motion into an address-backswing top section, a backswing top-impact section, and an impact-finish section; (c) extracting image frames (n-4) of the remaining operations corresponding to the standard operation using the small-section proportion table indicating the ratio of progress times between the operations set for each section divided in the step (b) step; And (d) matching each of the extracted n image frames with an image of a corresponding standard operation.

In another aspect of the present invention, there is provided a golf swing golf club according to the fourth aspect of the present invention, including four addresses including an address, a back swing top, an impact, and a finish, A golf swing motion analysis system for extracting n image frames corresponding to each of the predetermined standard motions of the golf swing operation (hereinafter referred to as " n ") and comparing / analyzing the golf swing motion with the standard motion,

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention unclear.

FIG. 2 is a diagram showing a golf swing operation divided into 16 operations in stages.

As shown in FIG. 2A, the swing trajectory is drawn as shown in FIG. 2B when the golfer performs a golf swing. When these are divided into 16 operations, the name of each operation is shown in FIG. 16 action consists of six actions between the address and the backswing top, three actions between the top of the backswing and the impact, and three actions between impact and finish, including the address, the backswing top, the impact, and the finish.

The golf swing starts from the address, reaches the backswing via the backswing, and then goes through the downswing and impacts the golf ball. After the moment of impact, the swing is completed by reaching the finishing operation through the follow-through motion.

The present invention creates a standard motion for 16 motions during the golf swing as described above and extracts image frames corresponding to 16 standard motions among the image frames recorded by the image photographing apparatus when the golf practitioner performs the golf swing, To synchronize the operation of the mobile terminal.

However, since the swing of golf is different for each person and the speed of the swing is different from the speed of the head to the finish from the address to the finish, the speed and the acceleration are different according to the position, so that one swing is simply divided by time to extract 16 motions There is a large error between the standard operation and the standard operation.

Therefore, a special method is required to extract image frames corresponding to 16 standard operations among the image frames of the golf swing motion recorded by the image photographing apparatus.

As a result of the statistical analysis, it was found that one time swing is divided into the address-backswing top section, the backswing top-impact section, and the impact-finish section. For example, as shown in FIG. 2B, the swing in the top-impact section of the backswing is in the order of the backswing top 8, downswing start 9, downswing 1 10, downswing 2 11, The time required to proceed from 8 to 9, 9 to 10, 10 to 11, and 11 to 12 varies from person to person, but the proportion of the time it takes to proceed is a constant proportional relationship.

Therefore, first, the address, the backswing top, the impact and the viewpoint of the finish are grasped through a sensor or the like to automatically extract an image frame corresponding to the address, the backswing top, the impact and the finish, (Hereinafter, referred to as a "small section ratio table") indicating the ratio of the time to the operation time obtained from the statistical analysis after dividing the top section of the backswing into an impact section and an impact-finish section It is possible to extract image frames corresponding to the 16 standard operations by automatically extracting image frames corresponding to the remaining operations.

Hereinafter, this will be described in detail with reference to FIG.

However, if the standard operation is set to 16, the standard operation and the corresponding image frame of the practitioner corresponding to the standard operation can be compared with the standard operation The present invention is not limited to this, and it is possible to arbitrarily set four or more numbers including an address, a backswing top, an impact, and a finish.

3 is a flowchart illustrating a golf swing operation analysis method according to a preferred embodiment of the present invention.

First, four or more standard operations including an address, a backswing top, an impact, and a finish are set (S300). The number of standard operations can be set arbitrarily, but is preferably set to 16 as described above.

When the practitioner enters the golf batting table and swings, it detects the address and the impact time point by a sensor provided in a plurality of rows in a row on the matte of the golf batting stadium, and records the address and impact An image frame corresponding to the viewpoint is extracted (S310).

As a result of the statistical analysis, the top point and the finish point of the backswing are located at the extinction point and the extreme point according to the time point and the impact point based on the time proportional to the type of the golf club such as the driver and the iron. For example, when the address point of the driver is 0% and the impact point is 100%, the top point of the backswing is positioned at a time point of about 70% (7: 3 end point of the address point and the impact point) It is located at approximately 150% time point (3: 1 outpoint of address and impact time). Therefore, a proportional table (hereinafter referred to as a "proportional table") indicating the temporal internal division ratio from the address point and the impact point to the top point of the backswing and the temporal external division ratio to the finishing point is created for each golf ball type, (Step S320), the image frame corresponding to the top of the backswing and the finish is extracted by analogy of the backswing top point and the finishing point by the interdigitary proportional table.

For precise measurement, it is effective to use the viewpoint of the backswing and the viewpoint of the finish point. However, since the golf ball is directed toward the sky rather than the ground and the position of the golf ball is not constant, There is a lot of inconvenience and cost burden to install. Therefore, the backswing top and finish time are not measured by the sensor but are derived from the statistically calculated ratio table.

In order to improve the accuracy of the analogy, the head speed, the swing trajectory, the head spot information data, and the correction data of the backswing top point according to the golfer's level according to the level of the golfer's head speed and swing trajectory, The level of the golfer is judged by the data of the ball point based on the head speed, the swing trajectory and the swing trajectory, which are measured by sensors provided in a plurality of rows in a plurality of rows in a row, and the backswing A step of correcting the top view and the finish view may be further included.

Further, when two or more video frames corresponding to the video frame or finish corresponding to the backswing top obtained by the analogous method as described above are extracted, the accuracy can be further enhanced by image processing. That is, a frame having the smallest image change rate can be selected by comparing an extracted frame with an adjacent image frame using a motion detection technique using image processing. Backswing tops and finishes include momentary stopping, so using this image processing will increase the accuracy of the analogy.

When the address time, the backswing top time, the impact time point, and the finishing time are calculated in S310 and S320, the entire swing is divided into the address-backswing top section, the backswing top-impact section and the impact-finish section, The image frame corresponding to the remaining 12 standard operations is extracted by the statistically calculated small-section proportional table (S330).

When the image frames corresponding to the preset 16 standard operations are extracted from the image frames of the golf swing motion recorded by the image capturing apparatus in the above manner, the extracted 16 image frames and the corresponding standard motion images are matched with each other And outputs them together (S340).

The method of outputting is as follows. The 16 image frames extracted and the corresponding image of the standard operation are displayed on a monitor or on a piece of paper (for example, A4 paper) of a predetermined size as shown in FIG. 6, The user can easily compare / analyze the motion of the user.

Hereinafter, a golf swing analysis system for implementing the golf swing analysis method will be described.

4 is a view showing an arrangement of a video image pickup apparatus and a sensor installed in a golf bat according to a preferred embodiment of the present invention.

As shown in FIG. 4A, a video photographing device such as a CCD camera is disposed on the front and side of a golf practitioner, records the swing state of the practitioner, and transmits the recorded video frame to an image analyzing apparatus to be described later in real time. The imaging device records 30 frames per second or 60 frames per second depending on the capabilities of the device. However, the arrangement and installation number of the image capturing apparatus can be arbitrarily changed and can be changed according to the performance of the frame capturing apparatus per second.

The sensor is mounted on a mat of a golf batting seat, and the detailed arrangement of the sensor is shown in Fig. 4B.

The sensors are arranged in three rows in total, eight in sensor row 1, 15 in sensor row 2, and 15 in sensor row 3. The reason for placing multiple rows of sensors in a row is to understand the head speed and swing trajectory. That is, the head speed can be known by the distance between each sensor row and the time difference between the sensor of each sensor row when the head passes over the sensor, and the swing trajectory can be determined according to which sensor of each sensor row senses the movement of the head . Also, information on the spot of the head from the swing locus can be inferred. Prior to the golf swing, the practitioner often performs a preparatory operation of shaking the golf club back and forth. In order to distinguish this preparation action from the actual swing, three sensor rows are arranged. In other words, when the three sensors are placed on the swing, the head passes through the sensor row 2 and the sensor row 1 in order, and then passes the sensor row 1, the sensor row 2, and the sensor row 3 again after a predetermined time interval. It is recognized as a swing.

However, the number of sensor arrays and the number of sensors disposed in the sensor arrays described above are merely examples, and various changes can be made within the number that can be supported by the controller connected to the sensor.
