  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  FIG. 1 is a diagram illustrating an embodiment of the swing diagnosis system K1. In FIG. 1, in addition to the swing diagnosis system K1, a subject h1, a golf club gc, and a golf ball gb are illustrated. Subject h1 is a right-handed golfer. Subject h1 may be a left-handed golfer.

  The swing diagnosis system K1 has a camera 4 and an information processing device 6. The camera 4 is connected to the information processing device 6 via the hub 5. The hub 5 may not be used. An example of the information processing apparatus 6 is a general-purpose computer. Two or more information processing apparatuses 6 may be used. In addition, an illumination device for sharpening the image is used as necessary.

  In the present embodiment, there are three cameras 4. The camera 4 includes a front camera 4a installed in front of the subject h1, a rear camera 4b installed behind the subject h1 in the flying line direction, and an upper camera 4c installed above the subject h1. The number of cameras 4 is not limited. From the viewpoint of accuracy of swing diagnosis, it is preferable to use two or more cameras 4 having different installation positions. From the viewpoint of accuracy of swing diagnosis, the swing diagnosis system K1 preferably includes a front camera 4a and a rear camera 4b, and more preferably includes an upper camera 4c.

  Note that the type of the camera 4 is not limited. Examples of the type of the camera 4 include a color CCD camera and a monochrome CCD camera. From the viewpoint of accuracy of swing diagnosis, the camera 4 capable of obtaining a color image is preferable.

  From the viewpoint of obtaining a still image of a swing that moves at high speed, the shutter speed is preferably short. A particularly preferable shutter speed is (1/500) seconds or less.

  FIG. 2 shows an example of the hardware configuration of the information processing apparatus 6. The information processing apparatus 6 includes an operation input unit 8, a data input unit 10, a display unit 12, a hard disk 14, a memory 16, and a CPU 18.

  The operation input unit 8 includes a keyboard and a mouse.

  The data input unit 10 includes an interface board (not shown) for inputting data output from the camera 4. Data input to the data input unit 10 is output to the CPU 18.

  The display unit 12 is, for example, a display. The display unit 12 can display various data while being controlled by the CPU 18. The display unit 12 displays each sheet (check sheet or the like) described later.

  For example, the CPU 18 reads a program stored in the hard disk 14 and develops it in the work area of the memory 16 and executes various processes according to the program. A preferred example of this program is spreadsheet software described later.

  The memory 16 is, for example, a rewritable memory, and constitutes a storage area, a work area, and the like for programs and input data read from the hard disk 14.

  The hard disk 14 stores programs and data necessary for data processing and the like. This program causes the CPU 18 to execute necessary data processing.

  Examples of the program that may be stored in the hard disk 14 include a program for selecting a still image corresponding to a specific swing position from a photographed swing image and the above spreadsheet software. This still image selection step will be described later.

  The hard disk 14 is an example of a storage unit that stores a check sheet. The camera 4 is an example of an image photographing unit that photographs a swing. The hard disk 14 is an example of an image storage unit that stores captured swing images.

  Processing for selecting a still image corresponding to a specific swing position from the captured swing image is a still image selection means. The process of step st200 described later corresponds to a still image selection unit. This process is performed by the CPU 18. For this process, an automated program is used as necessary.

  In the present application, the aspect during the swing is also referred to as “swing position” or simply “position”. The number of still images obtained by photographing is at least the same as the number of swing positions necessary for diagnosis. From the viewpoint of the degree of freedom of image selection, the number of still images obtained by imaging is preferably larger than the number of swing positions that require diagnosis.

  The processing for arranging the still image selected by the still image selection means at the position corresponding to the swing position of the check sheet is still image arrangement means. The process of step st300 described later corresponds to the still image arrangement unit. This process is performed by the CPU 18. For this process, an automated program is used as necessary.

  FIG. 3 is a flowchart showing an example of the procedure of the swing diagnosis method according to the present invention. In this swing diagnosis method, first, the swing of the subject h1 is photographed (step st100). Preferably, the entire swing (from address to finish) is taken.

  Preferably, the captured image data is stored as digital data in the image storage means such as the hard disk 14.

  For example, a moving image is obtained by this shooting. This moving image includes a large number of frames (still images). From these still images, a still image of a situation suitable for swing diagnosis is selected (step st200).

  In step st200, for example, the CPU 18 selects a still image corresponding to a specific swing position from among still images obtained by photographing. Details of this selection will be described later. The specific swing positions are, for example, eleven positions described later.

  Next, the selected still image (for example, a frame extracted from the moving image) is arranged on the check sheet (step st300). Each of the selected still images has a shooting time. On the other hand, the swing position is also chronological. Therefore, each of the still images can be arranged at an appropriate position corresponding to the swing position using the time information. In this step st300, for example, the CPU 18 arranges the selected still images in the position corresponding to the swing position of the check sheet in order of the shooting time.

  Next, swing analysis is performed (step st400). The swing is analyzed based on the selected still image. An auxiliary line is drawn on the image of the subject h1 as necessary. This auxiliary line is useful for swing analysis.

  Next, check items set for each swing position are designated (step st500). These check items are stored by the check item storage means. An example of the check item storage means is the hard disk 14. These check items are stored as a part of the check sheet cs. Check items that need improvement are specified. Specifically, a check item that needs improvement is clicked by the operation input unit 8 (mouse). An evaluation option is selected for the specified check item (step st500). Specification of check items and selection of evaluation options will be described later.

  Details of the evaluation method will be described below.

[Swing position]
4 and 5 are diagrams for explaining the swing position. In FIGS. 4 and 5, a typical swing is shown. The beginning of the swing is an address. The end of the swing is called the finish. The swing proceeds in the order of position (S1), position (S2), position (S3), position (S4), position (S5), position (S6), position (S7), and position (S8). FIG. 4 shows the positions (S1) to (S4). FIG. 5 shows the positions (S5) to (S8).

  The position (S1) is an address. Position (S2) is an aspect during takeback. The position (S3) is the top of swing (top). The position (S4) is a situation during the downswing. The position (S5) is also an aspect during the downswing. The position (S5) is a state in which the downswing has progressed more than the position (S4). The position (S6) is an impact. The impact is a moment at which the head of the golf club gc and the golf ball gb collide. Position (S7) is a phase during follow-through. The position (S8) is the finish. The finish means the end of the swing.

  The number of swing positions employed in the present invention is not limited. At least one swing position is adopted. From the viewpoint of accuracy of swing diagnosis, the swing position in the present invention is preferably set to address, at least one aspect during takeback, top of swing (top), at least one aspect during downswing, impact, and follow-through. Including at least one aspect and finish.

  Note that an error may be allowed when the swing position is adopted. Small errors have little effect on swing diagnosis. This tolerance is usually preferably within ± 0.02 seconds, more preferably within ± 0.01 seconds. For example, when the tolerance is 0.02 seconds, the swing position of “impact” may be 0.02 seconds before to 0.02 seconds after the moment when the ball actually hits the club.

  The impact can be determined from the image. The impact can be determined from the hitting sound. The impact can be determined by a sensor that senses the passage of the head. The method for determining impact is not limited.

The top of swing can be determined from an image, for example. As the definition of the top of swing, the following [Definition 1], [Definition 2] or [Definition 3] is possible. Definitions other than the following may be adopted.
[Definition 1] Time when the angle formed by the grip axis direction and the grip axis direction at the time of addressing is maximum.
[Definition 2] Time at which the magnitude of the head moving speed is minimum during the swing.
[Definition 3] Time instant at which the movement of the grip tip changes from the backswing direction to the downswing direction.
In the above [Definition 3], the grip tip is the end of the grip on the head side.

  FIG. 6 is a diagram for explaining the swing position employed in the present embodiment. In FIG. 6, the subject h1 and the golf club gc are shown in a simplified manner.

The swing position of this embodiment is subdivided from the swing position shown in FIGS. As shown in FIG. 6, the following eleven swing positions are employed in this embodiment.
Position 1 (p1): Address (golf club gc is approximately 6 o'clock)
Position 2 (p2): Takeback (position where golf club gc is approximately 8 o'clock)
Position 3 (p3): Takeback (position where golf club gc is approximately 9 o'clock)
Position 4 (p4): Takeback (position where the left arm is approximately horizontal)
Position 5 (p5): Top of swing Position 6 (p6): Down swing (turnback)
Position 7 (p7): Down swing (position where golf club gc is approximately 9 o'clock)
Position 8 (p8): Impact Position 9 (p9): Follow-through (when the golf club gc is approximately 4 o'clock)
Position 10 (p10): Follow-through (position where the right arm is substantially horizontal)
Position 11 (p11): Finish

  In some of the above swing positions, the swing image viewed from the front is regarded as an analog type watch. For example, the “8 o'clock position” means that the shaft of the golf club gc is at the 8 o'clock position of the watch in the image of the subject h1 as seen from the front.

  The number of swing positions adopted is not limited. From the viewpoint of accuracy of swing diagnosis, the number of swing positions is preferably 7 or more, and more preferably 9 or more. Specifically, the swing position includes address, two or more aspects during takeback, top of swing (top), at least two aspects during downswing, impact, at least one aspect during follow-through, and finish. Is preferred.

  When the number of swing positions is excessive, the accuracy of swing diagnosis does not improve so much, and the golfer receiving the diagnosis may be confused. From these viewpoints, the number of swing positions is preferably 13 or less, and more preferably 11 or less.

[Check sheet]
7 and 8 show an example of a check sheet. The check sheet cs1 in FIG. 7 and the check sheet cs2 in FIG. 8 are a set, and all the swing positions are described in this set of check sheets. 7 and 8 show a state before use.

  The check sheet cs1 and the check sheet cs2 have a description column P corresponding to each swing position. In the present embodiment, eleven description columns P are provided. This description column P includes a description column P1 for position 1, a description column P2 for position 2, a description column P3 for position 3, a description column P4 for position 4, a description column P5 for position 5, a description column P6 for position 6, a position 7 Is a description column P7 for position 8, a description column P8 for position 8, a description column P9 for position 9, a description column P10 for position 10, and a description column P11 for position 11.

  Each of the description columns P includes a comparative image arrangement unit V1, a captured image arrangement unit V2, a check item notation unit C1, and an evaluation entry unit E1. In the present embodiment, each of the description columns P is composed of eight cells of spreadsheet software.

  The comparative image arrangement unit V1 includes a front camera image arrangement unit V11 and a rear camera image arrangement unit V12. The comparative image arrangement unit V1 may further include an upper camera image arrangement unit.

  The captured image arrangement unit V2 includes a front camera image arrangement unit V21 and a rear camera image arrangement unit V22. The captured image placement unit V2 may further include an upper camera image placement unit.

  The still image selected in step st200 is placed in the captured image placement unit V2 (step st300).

  In step st300, the still image at position 1 is arranged in the captured image arrangement unit V2 at position 1. Similarly, the still image at position 2 is arranged in the captured image arrangement unit V2 at position 2. Similarly, the still image at position 3 is arranged in the captured image arrangement unit V2 at position 3. The same applies to positions 4 to 11. As described above, in step st300, the still image selected in step st200 is arranged at the position corresponding to the swing position of the check sheet cs.

  A comparative image placement unit V1 and a shot image placement unit V2 taken from the same viewpoint are arranged side by side. That is, the front camera image arrangement unit V11 and the front camera image arrangement unit V21 are arranged side by side. Further, the rear camera image arrangement unit V12 and the rear camera image arrangement unit V22 are arranged side by side. These arrangements facilitate image comparison. Upper camera images may be arranged side by side. That is, the upper camera image arrangement unit of the comparative image arrangement unit V1 and the upper camera image arrangement unit of the captured image arrangement unit V2 may be arranged side by side.

  The check item notation C1 has a first notation C11 and a second notation C12. The first notation C11 indicates check items related to the image of the front camera. The second notation unit C12 describes check items related to the image of the rear camera. Thus, the check item notation part C1 corresponding to each image is provided. The check item notation unit C1 may further include a third notation unit that indicates check items related to the image of the upper camera.

  The evaluation entry part E1 has a first entry part E11 and a second entry part E12. In the first entry part E11, an evaluation corresponding to the first notation part C11 is entered. In the second entry part E12, an evaluation corresponding to the second notation part C12 is entered. Thus, the evaluation entry part E1 corresponding to each check item notation part C1 is provided. The evaluation entry part E1 may further include a third entry part in which an evaluation corresponding to the third notation part is entered.

  The comparison image arrangement unit V1, the captured image arrangement unit V2, the check item notation unit C1, and the evaluation entry unit E1 corresponding to each position and each viewpoint are arranged adjacent to each other. For example, as shown in FIG. 7, a comparison image arrangement unit V1, a captured image arrangement unit V2, a check item notation unit C1, and an evaluation entry unit E1 corresponding to the front view of position 1 are arranged adjacent to each other. In the embodiment of FIG. 7, the comparison image arrangement unit V1 is arranged on the upper left, the photographed image arrangement unit V2 is arranged on the upper right, the check item notation unit C1 is arranged on the lower left, and the evaluation entry unit E1 is arranged on the lower right. ing. With these arrangements, it is easy to compare the image with the evaluation.

  In FIG. 7, only the portion related to the position 1 description column P <b> 1 is indicated by the reference numeral, but the same applies to the other description columns P. Each of the position entry columns P (P1 to P11) is provided with a comparison image arrangement unit V1, a captured image arrangement unit V2, a check item notation unit C1, and an evaluation entry unit E1.

In the present embodiment, for example, the following check items are described in the check item notation section C1 (first notation section C11) of position 1.
[Position 1: Front image]
・ Stance width ・ How to hold grip ・ Grip position ・ Ball position ・ Weight distribution ・ Head position ・ Body balance ・ Preparation and tension

For example, the following check items are written in the check item notation C1 (second notation C12) of position 1.
[Position 1: Back image]
・ Knee angle ・ Spine angle ・ Grip position ・ How to lower arms ・ Alignment ・ Shaft line angle

  As described above, the check item notation section C1 describes check items corresponding to each position and each viewpoint.

  Further, the check sheet cs2 has a comprehensive evaluation entry column T1 (see FIG. 8). The check sheet cs2 has a hitting data entry field D1 (see FIG. 8). These fields are useful for swing diagnosis.

  9 and 10 show the check sheet cs1 and the check sheet cs2 after use. In the front camera image arrangement unit V11 of the comparison image arrangement unit V1, an image of a comparison swing photographed by the front camera is arranged. In the rear camera image arrangement unit V12 of the comparison image arrangement unit V1, an image of a comparison swing photographed by the rear camera is arranged. In this embodiment, a professional golfer's image is used as a comparison swing. These comparative swing images are preferably placed in advance on the check sheet cs before placing the subject h1 image.

  An image of the subject h1 taken by the front camera is arranged in the front camera image arrangement unit V21 of the photographed image arrangement unit V2. An image of the subject h1 taken by the rear camera is arranged in the rear camera image arrangement unit V22 of the photographed image arrangement unit V2.

  The arrangement of the still image in the photographed image arrangement unit V2 is executed in the above step st300. Step st300 may be performed by software or the like. Step st300 may be performed by a mouse operation such as a human mouse operation (drag, paste, etc.), for example.

  The selection of a still image (frame) corresponding to a specific swing position (position 1 to position 11 in the present embodiment) is made in step st200. This step st200 may be automated or may be determined by a human. Preferably, this step st200 is automated by software. This software may determine each position based on, for example, a time difference from the impact. For example, the software may determine each position based on image processing capable of recognizing the position of the golf club.

  For example, a spreadsheet of spreadsheet software is used as the check sheet cs. In the present embodiment, Microsoft's trade name “Excel” is used as spreadsheet software.

  The spreadsheet has a plurality of worksheets. The check sheet cs is created on these worksheets.

  In the arrangement of step st300, a spreadsheet software function (for example, the “Excel” macro function) can be used.

  FIG. 11 is an enlarged view of a part of the check sheet cs1 in FIG. In FIG. 11, the description column P1 related to position 1 is shown enlarged.

  As described above, after the image is arranged in step st300, swing analysis (step st400) is performed. A swing analysis is performed based on the swing image of the subject h1. In this swing analysis, a comparative image is referred to. As a result of the swing analysis, check items to be improved are designated (step st500). Specifically, as shown in FIG. 11, a check item to be improved is clicked and a check mark is written.

  Next, an evaluation option is selected for the specified check item (step st500). FIG. 12 is a diagram for explaining selection of this evaluation option. These evaluation options are stored in the option storage means. This option storage means is, for example, the hard disk 14.

  In this embodiment, evaluation options are set using the pull-down list function of the spreadsheet software. A pull-down list pd corresponding to the check item is set in a cell adjacent to the check item. A list for displaying the pull-down list pd is stored in the option storage means. Specifically, a list for displaying this pull-down list pd is described in another cell (not shown).

  When a cell adjacent to the check item is clicked, a pull-down button bt1 is displayed (see FIG. 12). When this pull-down button bt1 is clicked, a pull-down list pd (evaluation option) is displayed. This display will be described. When a cell adjacent to the check item is clicked, the CPU 18 calls and displays the evaluation option stored in the option storage unit. This display process corresponds to the evaluation option display means. In the present embodiment, the CPU 18 of the information processing device 6 calls the evaluation option (pull-down list pd) stored in the option storage unit and displays it in the click area. This calling and display is the result of the CPU 18 executing a spreadsheet software program.

  An appropriate evaluation option is selected from this pull-down list. This selection is made by clicking on the screen using the operation input unit 8 (mouse). The CPU 18 displays only the clicked option from the evaluation options (pull-down list pd). This display process corresponds to the decision option display means. This display is achieved by executing a spreadsheet program. As a result, an evaluation that “the left load is too much. Let's have consciousness about the axis” is entered in the cell adjacent to the check item “weight distribution / head / waist position” (see FIG. 11). By providing evaluation options in this way, it is possible to make a diagnosis that is homogeneous and has little variation.

  As described above, the swing diagnosis system K1 preferably has evaluation option display means. As described above, the swing diagnosis system K1 preferably has a decision option display means.

  There may be check items for which no evaluation option is set. From the viewpoint of homogenizing diagnosis, it is preferable that evaluation options are set for all check items.

  FIG. 13 shows another sheet s2 on which the evaluation result for each swing position is described. The separate sheet s2 is created on a separate worksheet from the check sheet cs. The check sheet cs and the separate sheet s2 are included in the same file (file of spreadsheet software).

  In this separate sheet s2, the evaluation result of each position is extracted and shown from the check sheet cs. This separate sheet s2 is convenient when considering by focusing on the evaluation for each position. This separate sheet s2 is created using the reference function of the spreadsheet software. When the evaluation is entered in the evaluation entry part E1 in the check sheet cs, the cell in the separate sheet s2 refers to the written evaluation. Therefore, the evaluation entry part E1 of the check sheet cs is entered, and another sheet s2 is entered at the same time.

  FIG. 14 shows another sheet s3. The separate sheet s3 is created on a separate worksheet from the check sheet cs. The check sheet cs and the separate sheet s3 are included in the same file (file of spreadsheet software).

  The separate sheet s3 includes an overall evaluation comment entry field s31, a theme-specific evaluation entry field s32, and a step-by-step evaluation entry field s33. In the theme-specific evaluation entry field s32, not the evaluation for each position but the evaluation for each theme is entered. In the theme-specific evaluation entry field s32, evaluation results are entered for each theme such as “grip”, “posture (posture at address)”, “ball position”, and the like. As in the case of the separate sheet s2, the reference function for referring to the cells of the other check sheet cs may be used in the entry of the separate sheet s3. This sheet s3 can be used as a reference in swing diagnosis.

  FIG. 15 shows a personal data sheet s4 on which the golfer's personal information is described. The sheet s4 is created on a separate worksheet from the check sheet cs. The check sheet cs and the sheet s4 are included in the same file (a spreadsheet software file). FIG. 15 shows the state before entry. This sheet s4 can be used as a reference in swing diagnosis.

  FIG. 16 is an example of the chart sheet s5. The sheet s5 is created on a separate worksheet from the check sheet cs. The check sheet cs and the sheet s5 are included in the same file (a spreadsheet software file).

  The medical record sheet s5 has a lesson history entry field s51. By referring to this lesson history entry field s51, an appropriate diagnosis can be made even if the instructor is changed. The chart sheet s5 is provided with a guidance policy entry field s52. The guidance policy entry field s52 includes a description regarding future practice, a description regarding details of the instruction content, a description regarding the direction of instruction, and the like. This sheet s5 can be used as a reference in swing diagnosis.

  FIG. 17 is an enlarged view of a part of the medical chart sheet s5. Options are set in at least one item of the medical record sheet s5. Options are set by a pull-down list pd of the spreadsheet software. FIG. 17 shows a pull-down list pd in the column “Direction of cool now”. An appropriate option is selected from the pull-down list pd. Setting such options can contribute to homogenization of instruction.

  FIG. 18 shows an example of a physical check sheet s6. The sheet s6 is created on a separate worksheet from the check sheet cs. The check sheet cs and the sheet s6 are included in the same file (a spreadsheet software file). FIG. 18 shows a state before entry. In this sheet s6, items related to the physical ability of the golfer are described. This sheet s6 can be used as a reference in swing diagnosis.

  As described above, the check sheet cs, the chart sheet s5, the physical check sheet s6, and the like are each created on the worksheet. A file is formed by a plurality of worksheets. Preferably, a file is created for each golfer. By switching sheets on the spreadsheet software, all sheets (check sheet cs, chart sheet s5, etc.) can be browsed.

  In the above drawing, the name of the check sheet cs and the like is Mr. Yamada and the name of the medical record sheet s5 and the like is Mr. Yamamoto.

  FIG. 19 shows a check sheet cs according to still another embodiment. The embodiment of FIG. 19 does not have a comparative image. The check sheet cs may not have a comparison image. The check sheet cs may not include the comparative image arrangement unit V1.

  In the embodiment of FIGS. 7 and 8, the check sheet cs is divided into two sheets, but it is natural that one check sheet cs may include all positions.

  The present invention relating to a swing diagnosis method includes a step of preparing a check sheet before a swing evaluation is entered, a step of photographing a swing, and selecting a still image corresponding to a specific swing position from the photographed swing images. A step, a step of arranging the selected still image at a position corresponding to a swing position of the check sheet, and a step of performing a swing analysis based on the check sheet on which the still image is arranged.

  In the step of preparing a check sheet before the swing evaluation is entered, for example, a check sheet cs as shown in FIGS. 7 and 8 is prepared. A check sheet cs in which a comparison image is already arranged may be prepared. The step of photographing the swing is performed using, for example, the swing diagnosis system K1. In the step of selecting a still image corresponding to a specific swing position from the photographed swing image, selection is made in the same manner as in step st200, for example. In the step of arranging the selected still image at the position corresponding to the swing position of the check sheet, for example, the arrangement is made in the same manner as in step st300.

  The check items are not limited. From the viewpoint of appropriate swing diagnosis, preferable check items are as follows. The following items are for right-handed golfers, and for left-handed golfers, the left and right are reversed.

  The swing diagnosis system K1 may include a network. For example, a plurality of information processing apparatuses 6 may be connected via a network. With this network, information regarding swing diagnosis can be browsed from a plurality of information processing apparatuses 6. This network can contribute to sharing of information related to swing diagnosis. Information sharing can contribute to homogenization of swing diagnosis. Further, the image photographing means and the information processing apparatus 6 may be connected by a network. In this case, for example, swing diagnosis based on an image photographed at a remote place is possible.

  The information processing device 6 may be connected to the terminal device via a network. Examples of the terminal device include general-purpose computers and mobile phones. This network facilitates transmission and browsing of swing diagnosis information. When self-diagnosis information can be easily accessed, it is convenient for a person being diagnosed (for example, a student at a golf school).

  Examples of the network include the Internet and a LAN (local area network). A network using a dedicated line may be used. From the viewpoint of wide area, the Internet is preferable. When a network is used, it is preferable to implement security measures such as data encryption and user authentication.

  The systems and methods described above can be applied to golf swing diagnosis.
