A switch 158 for giving an instruction is provided.

 Next, the operation of the present embodiment will be described.

In the description of this operation, the diagnosis of the golf swing is performed by the following four displays. The first is coordinate data of the operating point of the captured swing form,
The difference from the model form of the comparison standard is displayed on the display 300 in a graph with the variation of the operating point coordinates (height) on the time axis as a horizontal axis. Second, the trajectory of the operation point is displayed together with the trajectory of the model form as a reference. Third, the trajectory of the above-mentioned operation point is displayed together with the image of the swing closest to the object at the time of impact, for example, stored in the frame memory 220. Fourth, a line drawing pattern in which the operation points are connected by line segments is generated, and the swing of the subject is displayed on the display 300 as a so-called change of the stick pattern.

Each of these diagnostic displays can be selected by a switch on the operation panel 104.

First, the imaging start instruction switch 158 enables measurement with this device, and the subject 105 swings,
The swing is photographed by the imaging unit 110 and converted into a digital signal by the sampling circuit 200. The image data converted into a digital signal by the sampling circuit 200 is stored in the frame memory 220. The digital signal of the operation image is converted into a binary signal by the binarization circuit 205, and the binary signal is input to the coordinate calculation circuit 250. The coordinate calculation circuit 250 converts the binary image data input from the binarization circuit 205 into an X coordinate signal and a Y coordinate signal. Then, among the converted coordinate signals, the operation points P ₁ to
Coordinate signal related to P ₄ are taken into CPU 260, various calculation data for operating point P ₁ to P ₄ is performed.

Regarding the calculation and comparison of the coordinate data of the operating point P in the swing, the applicant has previously described in Japanese Patent Application No. Hei.
Filed as 1299.

Further, the image signal stored in the frame memory 220 is
The data is stored while being updated by the plurality of frame memories 220. Then, the image of the frame at the timing instructed by the CPU 260 at the time of impact or the like is stored.

The applicant of the present invention applied for a measurement trigger technique such as a method of setting a trigger timing such as a timing of a frame stored in the frame memory 220 and a calculation of a coordinate signal of an operation point P on March 22, 1990. Further, it is also possible to provide a sensor, store the data in the frame memory 220 and calculate coordinate data at the trigger timing based on the sensor output.

Here, the flow of the swing diagnosis process in the processing device 103 is shown as a flowchart in FIG.

That is, the image signal input when the measurement start switch is turned on is stored while updating the frame memory, and the measured value is stored while being updated in the memory 270, and the display graphic memory 240 is also cleared. (S11, 12, 13).

With the start of the trigger, the update of the frame memory 220 is stopped, and the image under the trigger condition is stored (S16). Further, measurement is continued for a predetermined time after the trigger, for example, 0.5 seconds, the measured value is stored in the memory 270, and the value is held (S17, 18). As a result, the measured values before and after the trigger are stored in the memory 270. For this reason, as a trigger point at the time of impact, coordinate data of operation points before and after the impact is stored, so that data of a trajectory before and after the impact or data of a stick picture can be stored and displayed.

Depending on the display mode of the diagnostic display, the graph of the change in the height of the operating point is displayed (S20), the trajectory of the operating point is displayed (S21), and the trajectory of the operating point and the frame memory 220 are stored. An image synthesized with the image of the swing is displayed (S22), and a stick picture in which the operation points are connected by a line segment is displayed (S23). When it is necessary to save the data, the data is stored in the IC card (S24, S25).

Thus, for each of the four diagnostic modes,
Alternatively, display is performed sequentially.

Therefore First, an example of displaying the variations in the height of the position of the operating point P ₄ that is provided on the head of the diagnostician. Since it is preferable that the height position of the head does not fluctuate so much in the golf swing, the swing can be evaluated by displaying the state of the height fluctuation.

Coordinates the coordinate data of the operating point P ₄ that is input from the arithmetic circuit 250 is stored in the memory 270 as the X-coordinate data of the Y coordinate. The change of the height of the operating point extracted from the start of the swing of the operating point to the end of the data, that is, the Y-coordinate value is represented in a graph as time elapses, and this graph is stored in the graphic memory 240. . Further, stored in the graphic memory 240 similarly to the change in the height of the operating point P ₄ of the model to be compared based on the graph of the same time combined.

Then, it controls the image synthesizing circuit 230 to display the output of the graphic memory 240 on the display 300. The graph of the change in the height of the subject and the comparison reference is displayed in different colors so that the subject 105 can easily understand.

 This display example is shown in FIG.

This display is based on the data at the time of impact.
1.5 seconds and 0.5 seconds later, the change of the head position is shown. The upper graph shows the change of the head of a good person, and the lower graph shows the change of the head of a beginner. It is clear that beginners tend to face downwards when swinging. By simultaneously displaying and comparing the comparison reference and the measured data in this way, the weakness of the user's swing can be understood.

In this case, the change in the height can be set as the origin at the time of impact, and the graph can be shifted so as to represent the change before and after the change. By displaying in this manner, it is possible to display the deviation from the comparison reference before and after the reference point of the operation to be compared as the center, and give the deviation to the subject.

 Next, the operation of displaying the locus of the operation point will be described.

The coordinate position data of the operation point P stored in the memory 270 is extracted, and the trajectory is stored in the graphic memory 240 based on the X coordinate and the Y coordinate. In addition, the data of the comparison reference is stored in the graphic memory 240 as a locus. These two data are displayed on the display 300 via the image composition circuit 230. The trajectory of the operating point P in the measured swing and the trajectory of the comparison reference are displayed on the display 300 in a color different from the trajectory of the comparative reference so as to be easily seen by the subject.

FIG. 7 shows an example of this display. This example is a representation of changes in the operating point P ₄ attached to the head as the locus and displays the time at the time of impact with bright as a trigger at the time of impact. A trajectory T ₁ is of the diagnostician in FIG, T ₂ is the trajectory of the comparison reference. Note that, in drawing the locus, for example, the origin of the comparison reference data and the measurement data can be matched with the origin at impact or address. In addition, for example, when a trajectory of a different color is displayed before and after a trigger time point, for example, at the time of impact, the motion trajectory becomes easy for the person to be diagnosed to see. Furthermore, when drawing a locus such as a wrist motion point P ₂ and a club head motion point P _{1 having} a large positional fluctuation, a continuous locus is obtained by obtaining coordinates between the extracted motion points by approximation using a parabola or the like. It is preferable to draw as.

As the comparison reference data, professional swing data, swings one month before or one week before oneself, swings of oneself, and the like can be used. This comparison reference data can be stored in the IC card 121, and the data can be input from the IC card input / output device 120 and used. Conversely, the measured swing data can be stored in the IC card 121 and used for the next diagnosis.

Note that a floppy disk or the like can be used as the storage medium other than the IC card.

Next, an example will be described in which the image stored in the frame memory 220 and the above-described movement locus of the operation point are displayed together.

The frame memory 220 stores the image signal while updating the input frame. Then, a frame at a timing to be displayed, for example, an image at the time of impact is stored and saved in the frame memory 220 when the trigger condition is satisfied or the sensor inputs. The data of the locus of the operating point P is also stored in the graphic memory 240 by the above-described operation.

When the trajectory and the image display are selected by the switch 151 of the operation panel 104, the CPU 260 combines the swing image stored in the frame memory 220 with the trajectory stored in the graphic memory 240 to display the display 300. Is controlled to be displayed. For this, two images are combined using the image combining circuit 230 and displayed on the display 300.

This display example is shown in FIG. In this example it is represented together with the image during the trajectory of the operating point P ₄ provided on the diagnostician head impact.

Next, an example in which the operation points are displayed by stick pictures connected by line segments will be described. In the present embodiment, since TV images are used, the number of frames is 60 frames per second, and the image of each frame is processed. Therefore, it is possible to display by a stick pattern that connects the operation points of the golf swing with a line segment for each frame and displays the line segment as a series of operations. By displaying only the skeleton connecting the points of this operation, the subject can evaluate his or her own swing.

FIG. 9 shows a flowchart of this line drawing display. This line drawing display is an operation in which the image stored in the frame memory 220 and the line drawing are combined and displayed simultaneously. In displaying only a line drawing, the operation of storing and reproducing the frame memory 220 may be omitted.

First, initialization is performed (S31). That is, a storage capacity for two seconds and 120 frames is secured in the memory 270 for storing the measured values. H is the set value of the prohibition period of the frame memory 220 after the occurrence of the trigger (at the time of impact), which is 180 frames (3
Second) is set.

In step S32, with draw between operating points P _1, P _2, P ₃ at line segment trigger wait (ready) state, clear the screen. In step S35, a trigger state is displayed, and in step S40, a hold state is displayed by lamp display.

Step S33 performs the process shown in FIG. 10, updating the n-th memory 270 for storing measured values,
The frame memory 220 is updated.
The figure updates the nth memory 270 and controls it to wait for the triggering swing.

When the trigger occurs in step S34, the number of updated frame memories is updated by the processing in steps S36 to S39. For this reason, the frame at the time of the trigger is saved.
Then, to display the line drawing which connects the operating points P _1, P _2, P ₃ of each frame in the segment at step S40. In step S41, the image at the time of impact stored in the frame memory 220 and the display of the line drawing are combined and output to the display 300 for display.

In steps S43 to S46, once a trigger is applied, the frame memory 220
Is controlled so as to save the image signal stored therein.

In this way, the operating point of each frame for 2 seconds
A line drawing connecting P _{1 to} P ₃ with a line segment is combined with the image at the time of the trigger stored in the frame memory 220 and displayed.

In the above-described flowchart, the frame memory 22
Although the image signal stored in 0 is also output at the same time, stick pictures at the operation points P _{1 to} P ₃ can be displayed except for the control of the frame memory 220. FIG. 12 shows a display example of a stick picture in which the operation points P _{1 to} P ₃ are connected by line segments. However, in this example, the number of line segments to be displayed is thinned out for the sake of explanation, and all the measured frames are not displayed.

By displaying the line segments in this manner, it is possible to see the blur due to the swing, the degree of the hollow through, and the like on one screen.

Further, in the operation for connecting the operating point P ₁ to P ₃ of the above-described line segments, instead of connecting directly operating point P _1, P _2, P ₃ at line segment, for example, Become so takes P ₂ points, it can also be configured to display signed by segments of P ₁ P _2, P ₂ P _3. This is the operating point
Although P ₂ is provided in the wrist, so not necessarily represent the center bending in swing is to correct the deviation amount.

Further, in the operation of connecting the operation points P _{1 to} P ₃ with line segments, for example, at the time of impact, operation points P _{1 to} P ₃ such as a point 45 ° before impact and a point 90 ° after impact
It is preferable to obtain the coordinate value of from the preceding and following coordinate values, display the stick picture at this time, and display the stick picture while changing its display color from other line segments.

Japanese Patent Application No. 1-161299 discloses a configuration for obtaining the angle or the coordinate value at the time from the coordinate value of the nearby measured value.
And is performed by calculation such as interpolation or linear approximation.

13 shows an example in which the operation diagnostic device of the present invention shown in FIG. 13 is a portable device.

This operation diagnostic device includes an imaging unit 110, a processing device 10
3, display 102, operation panel 104, printer 122, speaker
126, a microphone 128, and an IC card input / output device 120 are housed in one portable housing 112. As the display 102, a flat display device such as a liquid crystal display device is used. The apparatus further includes a battery power source and is configured to operate on the battery power source.

When using this device, the person to be diagnosed stands and swings at a position opposite to this device, and this swing is photographed and measured by an imaging unit, and the measurement result is displayed on a display as required, Alternatively, output to a printer or store in an IC card. In this example, the impact trigger timing is set by the sensor 130 provided at a position where the address position is desired, and a start switch is provided as an accessory to the sensor device.

As described above, since the trigger can be detected when the trigger condition of the operation point is satisfied as described above, it is not always necessary to provide a sensor. Since this device operates on battery power, it can be easily used even on a bat at a driving range or on a green where commercial power cannot be easily obtained.

In addition, since the operation diagnosis can also be performed on a swing image photographed by a VTR, it goes without saying that a VTR device other than a TV camera can be used as the imaging unit 110.

Here, the functions of the speaker 126 and the microphone will be described. The speaker 126 outputs a sound or a buzzer sound as to whether the trigger has been normally performed. Thus, the end of the measurement can be known. Also microphone
128 can be used as a measurement start instruction by voice instead of pressing the measurement start instruction switch. In this case, it is necessary to provide an audio processing device.

〔The invention's effect〕

As described above, the present invention captures the swing of the subject as image data, measures it, and displays the measurement data together with the image at the time of the desired swing, or displays a stick picture of the swing. Can be.

In addition, since it is not a large device and it is possible to diagnose swing easily, for example, make a diagnosis in preparation for a driving range,
Or there is an advantage that can be used for one's practice.
