Description

System for correting the swing motion of golfer}

The present invention relates to a golfer's posture correction system, and more specifically, the golfer can shoot the swing posture for a predetermined time before and after the time detected by the sensor unit after hitting the golf ball using the golf club can be seen by the golfer It is about a golfer's posture correction system that can correct the posture by reproducing it and comparing it with the expert swing posture.

The golf population is soaring and golfers are practicing a lot of swings on the golf practice grounds, not on the field, in order to score good or best on the field. However, it was impossible for golfers to see their swing position with their own eyes and evaluate themselves by correcting their postures, unless specially trained professionals (or coaches) practiced them on the practice range.

In order to solve this problem, various types of exercise devices and / or orthodontic devices for correcting the posture of a golfer have been developed and used. One of these devices was to shoot a golfer's swing posture with one or two cameras and then correct the posture while viewing the swing posture through the monitor screen.

However, the correction device as described above has a disadvantage in that it does not maintain the correct swing posture causing the burden on the golfers. In other words, the golfer swings with the perception that he is shooting his swing position, so the correct swing position is not obtained.

In addition, conventional calibration devices are difficult to operate easily, so most golfers are afraid to use the calibration device. In other words, the conventional calibration devices are operated by pressing the start recording button to shoot the golfer's swing, and then pressing the stop button and playing again after standing in front of the camera. It was useless for golfers who are not used to it. In addition, since the user cares about the operation of the device has a disadvantage of not being able to swing correctly.

In addition, there is a disadvantage in that the golfer's swinging motion is taken, and thus, unnecessary motions such as a preliminary motion performed by the golfer to hit the golf ball are stored and stored. In order to solve these shortcomings, the calibration device may be operated with the help of an administrator, but there is still inconvenience in using the calibration device.

The present invention is to solve the above problems, an object of the present invention is a golfer shoots a swing posture for a predetermined time before and after the time detected by the sensor unit after hitting the golf ball using a golf club ball It is to provide a golfer's posture correction system that can correct the posture by reproducing it and comparing it with the expert swing posture.

Another object of the present invention is the golfer is automatically operated after hitting the golf ball to shoot the swing of the golfer can freely swing the swing, the posture of the golfer easy to shoot and play even without the help of others To provide a calibration system.

Hereinafter, a golfer's posture correction system of the present invention will be described in detail with reference to the accompanying drawings.

1 is an external perspective view of a posture correction system of a golfer according to the present invention. As shown, the display unit 60 is located on the upper part of the stand 3, and although not shown, an apparatus for image processing is installed inside the stand 3.

When the golfer is set to the automatic play mode after hitting the golf ball in the practice position, the posture is immediately corrected while watching his swing form through the display unit 60 without the need for a separate device operation action. In particular, in order to provide convenience to the golfer, the display unit 60 may be configured using a conventionally used touch screen. When the touch screen is used, command buttons for command input of the command input unit are displayed on the touch screen.

Alternatively, a command or data may be input by using a separate command input unit such as a keyboard, a mouse, or a touch pen, or may be added as an auxiliary device. In the drawings, cameras for photographing a golfer's swing posture are not shown and will be described with reference to FIG. 3. In addition, the golfer's posture correction system is preferably installed at the rear of the golfer where the camera is not installed so as not to attract the golfer's attention.

Cameras for photographing the golfer's swing posture are preferably provided so that the golfer can be photographed in four directions, namely, front, right, left, and top. 3 shows an installation position of cameras installed around a golfer.

As shown in the drawing, the golfer 5 takes the preliminary posture to swing in a state where the golfer climbs on the pad 38a placed at a predetermined position to swing by holding the golf club. At this time, the golfer may perform the shadow swing operation as in the prior art, and the photographing operation by the camera is not performed during the preliminary operation. Therefore, as in the conventional calibration apparatus, the golfer or the manager does not need to operate the calibration apparatus to photograph the swinging motion of the golfer.

The first, fourth, and fourth cameras 12, 14, 16, and 18 are respectively installed at a predetermined distance from the front, the right side, the left side, and the top of the golfer. In the drawings, the golfer is photographed using four cameras, but the number of installations of the cameras may be changed to better understand the golfer's swing position.

The first-fourth cameras 12, 14, 16, and 18 may use a camera capable of outputting an NTSC signal or a PAL signal, and may be easily configured using, for example, a CCD camera. . In addition, by using a resolution of 400,000 pixels or more and using a box-type camera, it is desirable to protect the camera from external shocks.

In addition, in front of the golf ball 5, the sensor unit 30 for detecting the moving state of the golf ball (5) is provided. The sensor unit 30 detects the golf ball 5 when the golf ball 5 is hit by the golf club and passes the side of the sensor unit 30 during movement, and the control signal of the calibration system (not shown). To pass. In the present invention, the sensor unit 30 serves as a switch that provides a time point for photographing the swing operation of the golfer.

A block diagram of a preferred embodiment of the posture correction system of the present invention is shown in FIG. As shown, the camera unit 10, which is installed on the front, right side, left side and top of the golfer, respectively, including a 1-4 camera (12, 14, 16, 18) for shooting the golfer, the first The image processing unit 20 for processing and storing the image input from the -4 camera (12, 14, 16, 18), the object detection sensor unit 30 for detecting the golf ball (5) moved by the golfer hitting ), When the movement signal of the golf ball 5 is detected from the sensor unit 30, the posture of the golfer photographed through the image processing unit 20 is controlled to be stored for a predetermined time before and after the detection time and to perform a specific command. A swing of a golfer photographed through the image processor 20 according to a signal from the controller 40, a command input unit 50 for inputting a command to perform a specific function to the controller 40, and a signal from the controller 40. A display unit 60 for visually displaying the posture is included.

The first-fourth cameras 12, 14, 16, and 18 are included in the camera unit 10, and the camera unit 10 includes all camera brackets, camera holders, adapters, video, and power cables in addition to the cameras. Doing. Image data photographed from the first to fourth cameras 12, 14, 16, and 18 are respectively output as NTSC or PAL signals and input to the image processor 20 through an image cable.

The image processing unit 20 is for temporarily storing the converted video data after converting an input NTSC or PAL signal into a digital signal. For this purpose, the image processing unit 20 includes an image processing unit 22 and a memory unit 24. The image processing unit 22 converts signals input from the first through fourth cameras 12, 14, 16, and 18 into digital data, and then stores the screen at 120 frames per second (four cameras x 30 frames). do. Of course, if one camera is used, 30 frames per second, and if two cameras are used, 60 frames per second will be processed.

The moving picture data is stored in a conventional image file format such as jp (e) g, gif, or in a moving image file format such as mp (e) g, avi. In the case of being stored as an image file, the stored frames can be output quickly in order to achieve the same effect as a video file.

The moving picture data stored at this time is not stored in a storage device such as a hard disk but temporarily stored in a memory device such as a buffer memory. This does not store unnecessary video signals, that is, signals other than the swing posture of the golfer, thereby reducing the load of the image processing unit 22 and maximizing the storage capacity. The memory unit 24 includes a data storage device such as a buffer memory and a hard disk.

The image processing unit 20 uses a dedicated device for image processing or a Windows XP OS, a CPU having a speed of 2.4GHz, a 256MB RAM memory, an 80GB hard disk, a display unit using an LCD monitor, a four channel camera. It can be configured using a personal computer having a signal input terminal. In this case, the controller 40 of the posture correction system of the present invention may use a CPU of the personal computer, and the display unit 60 described above may also use a touch screen connected to the personal computer.

The image processing unit 20 stores the video signal temporarily stored according to a command output from the control unit 40 as a predetermined time range. The predetermined time may be, for example, 1 second to 6 seconds, and may be input by the command input function through the command input unit 50. For example, if the predetermined time is 1 second, the swing motion for a total of 2 seconds is stored for each second before and after the detection time.

The control unit 40 includes a control program and control data for controlling the golfer's posture correction system of the present invention, and performs a command input from the command input unit 50. Commands to perform may be, for example, shooting and storing, monitoring, autoplay, setting, search mode, etc., and may also be other additional functions, such as panorama mode, print mode, and the like.

The sensor unit 30 detects the movement of the golf ball 5 and detects the movement of the golf ball using a plurality of light receiving units and light emitting units. 4 shows an example of the sensor unit 30 according to the present invention.

As shown, the sensor unit 30 is separated by a predetermined distance apart as a pair of sensor bars 36 extending vertically, the golf ball 5 passes between them. A plurality of light emitting units 34 are arranged at regular intervals on one side of the sensor bar 36, and a light receiving unit 32 corresponding to receiving light emitted from the light emitting units 34 is provided at the sensor bar 36 at an opposite position. ) (Indicated by the dashed lines) are installed. Although not shown in detail, the light receiving unit 32 and the light emitting unit 34 are connected to the control unit 40 through a wire.

When the golfer hits the golf ball 5 while the light is emitted from the light emitter 34, the light is blocked by the golf ball 5, and the light receiver 32 detects the blocked state of the light. do. The blocking state detected by the light receiving unit 32 is input to the control unit 40, and when the moving state of the golf ball 5 is detected from the light receiving unit 32, the control unit 40 immediately transmits a control signal to the image processing unit 20. Outputs a control signal to store the temporarily stored image data.

Since the light emitting unit and the light receiving unit are each composed of three columns, when the sensor bar is used, it is possible to obtain data for predicting the hitting speed, the hitting angle, and the flying distance of the golf ball.

In addition, as shown in the drawing, the sensor unit 30 may be configured by integrally installing the light emitting unit 34 and the light receiving unit 32 on one sensor bar 36 instead of a pair of sensor bars. . In this case, the structure of the sensor unit 30 has the advantage of being simplified, but there is a possibility that a malfunction may occur in the detection of the movement of the golf ball 5, such as the calculation of the hitting speed, the hitting angle and the flying distance of the golf ball 5, etc. There may be difficulties in providing advanced features.

In addition, in the present invention, it is possible to use an acoustic sensor rather than an optical sensor for the movement detection of the golf ball (5). That is, the sound generated when the golfer hits the golf ball 5 using the golf club is heard by using a microphone, and the sound signal is analyzed to detect the time of movement of the golf ball 5.

This can be easily configured using a microphone, an amplifier for amplifying a signal of the microphone, and an A / D converter (not shown) for converting a signal output through the amplifier to be recognized by the controller 40. Can be. In the case of using a microphone, as in the case of using one sensor bar, it is obvious that there are some limitations in the function prediction.

The position detection switch 38 is installed under the pad 38a of FIG. 3 and used to detect whether the golfer is in a position for swinging. The detected signal is input to the controller 40, and when the signal is input from the position detection switch 38, the controller 40 may output a control signal to the image processor 20 to photograph the golfer's situation. have. Even in this case, the captured video data is temporarily stored in the buffer memory.

By doing so, there is an advantage that the unnecessary photographing operation of the image processor 20 can be eliminated. Of course, even in the absence of the position detection switch 38, the golfer's posture correction system of the present invention operates normally.

The command input unit 50 is used for input of a setting time for permanently storing an image photographed by the image processing unit 20, a command input for displaying a stored video, and data input for detailed setting. The command input unit 50 may be installed on the screen of the display unit 60 using a touch screen method or an input device such as a keyboard, a mouse, a touch pen, or the like.

As shown in FIG. 1, the display unit 60 displays an operation state of the posture correction system of the present invention, outputs a stored video of a golfer, or displays a menu screen for inputting a specific command. The display unit 60 may be configured using a CRT or LCD monitor on which a touch screen function may be installed.

In the present invention, the printer 70, the CD / DVD writer 80, and / or the communication unit 90 may further be connected to provide additional functions. The printer 70 is for printing a posture of a golfer. For example, the printer 70 selects and edits 12 screens for each channel, and prints and outputs the selected / edited screen. Golfers can refer to the printed screen to help him correct his swing position.

The CD / DVD writer 90 is used to record moving images photographed by the camera to a file. In other words, each moving picture file photographed and stored by the first to fourth cameras 12, 14, 16, and 18 is recorded on a CD or DVD, which is a storage medium, for the golfer to carry. The file can then be replayed and used to correct the golfer's posture with the help of a golf coach.

In addition, the communication unit 90 is connected to an internet communication network or a dedicated line for transmitting and receiving data, and may be an ADSL / VDSL modem or a cable modem. At this time, the control unit 40 further includes a control program for controlling the communication unit. The swing posture video of the golfers transmitted through the communication unit 90 is collected by a server computer (not shown), the posture is analyzed by an expert, and the analysis result is received again through the communication unit 90 to display the display unit ( 60) can be output. Therefore, golfers can receive advice from posture-correction specialists regardless of time and space.

In the present invention, not only the posture corrected by the expert, but also the accurate or desirable swing posture of the expert or professional golfer (hereinafter referred to as expert) can be stored and compared with the golfer's swing posture in real time. For example, a professional shoots a swinging posture in the same manner as a regular golfer and sets it as the reference swing position or the standard swing position.

When the golfer swings with the reference swing posture (or standard swing posture) saved, the player shoots and saves it, and then the golfer selects the function to compare the reference swing posture with the swing posture of the golfer in the posture correction system. A golfer may display a display screen comparing the front of the expert and the front of the golfer, the right side of the expert and the right side of the golfer, the left side of the expert and the left side of the golfer, and / or the upper part of the expert and the upper part of the golfer, respectively, at 60. Can compare his posture and correct it.

Comparing the swing posture, it is possible to compare the four stored channels simultaneously or sequentially one channel, it is advantageous that the golfer can easily recognize the posture to compare sequentially one by one channel.

This is especially possible with the synchronization of the shooting time in the present invention. In other words, in the present invention, the video is stored for about 1 second to 3 seconds before and after the golf ball passes through the sensor unit 30. When the golf ball 5 passes through the sensor unit 30 when the golf club is hit by the golf club, the distance between the golf ball 5 and the sensor unit 30 is short. Therefore, the video taken is almost the same state over time, so golfers can easily compare their swing posture while watching the swing posture of the expert.

The operating state of the posture correction system of the golfer of the present invention having the configuration as described above will be described with reference to FIG.

When the golfer is positioned on the pad 38a installed at the turn at bat for swing practice, the position detection switch 38 embedded in the pad 38a is operated to input a signal to the controller 40. When a signal is input, the controller 40 operates the image processor 20 to start capturing and temporarily storing the golfer's operating state.

Then, when the golfer hits the golf ball 5 using the golf club, the golf ball 5 moves at a high speed. When the moving golf ball 5 is detected by the sensor unit 30, the sensor unit 30 outputs a detection signal accordingly. The control unit 40 checks the movement detection time of the golf ball when the detection signal is input from the sensor unit 30, and outputs a control signal to the image processing unit 20 to store a video for a predetermined time before and after the identified time. . The image processing unit 20 stores a video for a predetermined time of the golfer temporarily stored according to the control signal. This completes the saving of the video about the golfer's swing.

After the video storage for the predetermined time is completed as described above, the control unit 40 waits for a function command input from the command input unit 50. The function command may be, for example, a monitoring mode, an automatic playback mode, a setting mode, a search mode, or the like. When a specific function command is input, the controller 40 performs an operation according to the command.

6 shows an example of a monitoring mode, which is a swing posture monitoring screen through four divided screens. Although not well displayed in the drawings can provide a digital high-definition screen, and provides a simple operation menu through the touch screen at the bottom of the screen. Through this monitoring screen, the swing posture can be confirmed in three dimensions.

Fig. 7 shows an example of the automatic regeneration mode, which automatically regenerates swing postures in four directions. This automatic replay has the advantage that the golfer can immediately check his swing position after the swing. In the auto play mode, sub-functions such as pause and frame-by-frame playback can be provided, and the swing posture can be corrected using a drawing function using a touch pen.

If this function is set in the auto play mode, the golfer swings the golfer's swing motion automatically after a certain period of time after the golfer hits the golf ball so that the golfer can visually check his swing position without a separate motion. . For the convenience of operation, it is preferable to set this automatic playback mode as the default mode.

FIG. 8 illustrates an example of a setting mode, and may adjust image quality for each camera channel, adjust pre and post recording time, select a storage medium, and adjust auto play speed and start time.

9 also shows an example of the search mode, which provides a golfer's swing date, swing time display, search speed adjustment, pause, forward and backward frame unit search, storage drive, search through date and time. After searching his swing position through the search mode, the swing position can be automatically reproduced to view the swing position, or the panorama function as shown in FIG. 10 or the printing function as shown in FIG. 11 can be executed.

FIG. 10 is a panorama function and displays 8 screens for each channel, and stores a swing posture correction and a swing posture correction file through a drawing function. The file is stored in the recording medium for permanent storage via the CD / DVD writer 80. Using the stored recording medium, the golfer can retrieve the recording at home.

In addition, FIG. 11 is a printing function in which a golfer selects, edits, and prints a screen while watching a video of his swing position.

According to the present invention as described above, the golfer shoots and reproduces the posture for a predetermined time before and after hitting the golf ball using a golf club at various angles, and also corrects the posture by comparing it with an accurate swing posture of an expert.

In addition, since the golfer is operated after hitting the golf ball to shoot the swing of the golfer can freely swing the swing, it is easy to shoot and play without the help of others.
