The present invention provides a motion diagnosis device that photographs the motions of a person to be diagnosed and analyzes the motions. By displaying the point as a graphic image or displaying it together with a motion image, the motion of the patient can be easily and easily understood by the patient.

[Conventional technology]

BACKGROUND ART Analysis and evaluation of movements in sports and the like have traditionally been performed by instructors. For example, when practicing a golf swing, an instructor would watch the golf swing and give appropriate advice. If no instructor was present, the swing would be recorded on a VTR or film, and the instructor would watch the swing and give advice by playing it back.

Alternatively, there is a technique in which the swing form of the person to be diagnosed is photographed on a VTR, or the swing form is taken using a storage device capable of taking time-lapse images, such as an electronic still camera, and the swing form is reproduced and displayed to the person to be diagnosed in the form of an exploded photograph.

Furthermore, there have been devices used to evaluate golf swings that measure the speed and direction of the ball or the speed of the club head at the moment of impact and display the numbers.

[Problem to be solved by the invention]

However, if a person tries to practice alone, the effect of the practice will not increase because, without an instructor, the person will not be able to diagnose the swing and give appropriate advice. Furthermore, even if the swing is replayed and displayed to the patient in the form of a disassembled photograph, the patient will simply see his or her own swing, and it is difficult to know what points to focus on when evaluating the swing. However, there is a problem with not being able to properly evaluate the swing.

Further, even if only the data were displayed, it was insufficient as a swing evaluation device because the person being diagnosed would not be able to evaluate his or her own swing using only the data.

The present invention solves the above-mentioned problems of the prior art, and aims to provide a motion diagnosis device that allows even a single person to be diagnosed to evaluate their own form and diagnose their motion. do.

[Means to solve the problem]

The present invention provides a means for sampling an image of a patient's movements and converting it into a digital signal, and a device configured to analyze the movement of the patient from the image data converted into the digital signal. In a motion diagnosis device equipped with a measuring means for extracting coordinate data of each of the above operating points and a display means for displaying the measurement results of this measuring means, the coordinate data of the operating points extracted by the above measuring means are compared. The present invention is characterized by comprising means for simultaneously displaying coordinate data of a motion point of a reference motion.

Preferably, the variation in the coordinate position of at least one operating point with respect to time is displayed together with the variation with respect to time of the operating point of the comparison reference.

Further, it is preferable that the locus of at least one motion point is displayed together with the locus of the corresponding comparison reference motion point.

Further, the present invention is characterized in that an image storage means is provided for storing photographed images frame by frame, and the coordinate data of at least one operating point is simultaneously displayed on the display means, superimposed on the image stored in the image storage means. do.

As this display, it is preferable to simultaneously display the locus of at least one motion point together with the image stored in the image storage means at a predetermined timing.

Furthermore, the present invention is characterized by comprising means for connecting motion points with line segments, and means for displaying a plurality of frames of the line segments between the motion points connected by this means on the display means.

It includes a means for calculating the coordinate data of the operating point at a pre-specified time point from the coordinate data of surrounding operating points, and emphasizes the line segment between the operating points at the specified time point based on the calculated value. It is preferable to provide means for displaying the information.

Furthermore, it is preferable to display the line segments between the motion points together with the image stored in the image storage means.

Note that it is preferable that the device be mounted in a portable housing and provided with a battery power source for driving each means.

[Effect]

The photographed image of the patient's movements is digitally sampled and converted into a digital signal including a binary signal. The image data converted into the digital signal is calculated, and coordinate data is calculated and obtained for one or more operation points therein.

From the coordinate data of this motion point, the motion locus of the motion point provided, for example, at the head position of the subject is determined and displayed on the display device. The images taken at the same time are stored in a frame memory, and the above-mentioned movement locus is displayed on the image of the designated movement and presented to the person to be diagnosed.

In addition, the locus of movement of this operating point and the locus of movement of the operating point of the model used as a comparison standard are displayed at the same time, so that the patient can clearly see the difference in the locus of movement of the two operating points. or display it together with the motion image read out from the frame memory described above so that the person to be diagnosed can evaluate his or her own motion.

Furthermore, a plurality of motion points are connected by line segments and displayed as a stick pattern on the display device.

As a result, the motion analysis result is given in the form of a stick pattern, making it easier for the person to be diagnosed to evaluate his or her own motion.

Next, the operation of the device of this embodiment will be explained.

In this explanation of the operation, it is assumed that the golf swing is diagnosed using the following four displays. First, the difference between the coordinate data of the motion point of the photographed swing form and the reference model form for comparison is displayed on the display 300 as a graph of the variation of the motion point coordinate (height) with the time axis as the horizontal axis.

Second, the locus of the operating point is displayed together with the locus of the model form as a comparison standard. The third is frame memory 22
For example, the trajectory of the above-mentioned motion points is displayed together with the image of the swing closest to the impact at the time of impact, which is stored in 0. The fourth method is to generate a line drawing pattern in which motion points are connected by line segments, and to display the swing of the patient on the display 300 as a so-called change in the stick pattern.

Selection of each of these diagnostic displays can be made using a switch on the imitation panel 104.

First, the imaging start instruction switch 158 enables measurement with this device, the person to be diagnosed 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. Further, the digital signal of the motion image is sent to the binarization circuit 205.
The binary signal is converted into a binary signal by the coordinate calculation circuit 2.
50 is input. The coordinate calculation circuit 250 is the binarization circuit 2
The binary image data input from 05 is converted into an X coordinate signal and a Y coordinate signal. Of these converted coordinate signals, the coordinate signals related to the operation points P1 to P are CP
The data is taken into U260 and various calculations are performed on the data regarding operation points PI to P4.

Regarding the calculation and comparison of the coordinate data of the motion point (P) in this swing, the applicant has previously published patent application No. 1-16
It has been filed as No. 1299.

Furthermore, the image signal stored in the frame memory 220 is
The data is stored while being updated in a plurality of frame memories 220. Then, an image of a frame at a timing commanded by the CPU 260, such as at the time of impact, is saved.

The applicant filed an application on March 22, 1990 regarding measurement trigger technology such as how to determine the timing of frames stored in the frame memory 220 and the trigger timing for calculating the coordinate signal of the operation point P. Further, it is also possible to provide a sensor and determine the trigger timing based on the output of the sensor to perform storage in the frame memory 220 and calculation of coordinate data.

Here, the flow of swing diagnosis processing in the processing device 103 is shown in FIG. 5 as a flowchart.

That is, the image signal input when the switch to start measurement is turned on is stored while updating the frame memory, the measured value is stored while being updated in the memory 270, and the display graphic memory 240 is also cleared. (Sll, 12.13).

When the trigger starts, updating of the frame memory 220 is stopped and the image under the trigger condition is saved (S16).

In addition, the measurement is continued for a predetermined period of time after the trigger, for example, 0.5 seconds, and the measured value is stored in the memory 270 and held (S17.18). It will be stored in the memory 270. For this reason, when a trigger point is set at the time of impact, the coordinate data of the motion points before and after the impact are stored, and thereby the locus before and after the impact or the data of the stick picture can be stored and displayed.

Depending on the display mode of the diagnostic display, a graph of changes in the height of the operating point is displayed (S20), a locus of the operating point is displayed (321), and the locus of the operating point is stored in the frame memory 220. Display an image synthesized with the swing image (322), and display a stick picture with line segments connecting the motion points (323>).Also, if it is necessary to save the data, store the data on the IC card. (S24.25).

In this way, the four diagnostic modes are displayed individually or sequentially.

Therefore, first of all, we set a motion point on the head of the person to be diagnosed.
An example of displaying a change in the height of the position of P4 will be explained.

In the Corfu swing, it is preferable that the height position of the head does not change much, so the swing can be evaluated by displaying the state of the height change.

The coordinate data of the operation point P4 input manually from the coordinate calculation circuit 250 is stored in the memory 27 as X coordinate and X coordinate data.
It is stored as 0. Among these data, changes in the height of the motion point extracted over time from the start to the end of the swing of the motion point, that is, the X coordinate value, are expressed in a graph over time, and this graph is stored in the graphic memory 240. . In addition, the changes in the height of the operating point P4 of the model used as a comparison standard are graphed over the same time, and the graphic memory 24 is also
Store at 0.

Then, the image synthesis circuit 230 is controlled to display the output of the graphic memory 240 on the display 300.

The graphs of changes in the heights of the person to be diagnosed and the comparison standard are displayed in different colors so that the person to be diagnosed 105 can easily understand them.

An example of this display is shown in FIG.

This display is based on the data at the time of impact, and the previous 1
．． It shows the change in the head position after 5 seconds and 0.5 seconds later.The upper graph shows the change in the head position of a skilled player, and the lower graph shows the change in the head position of a beginner. Beginners will find that it is easy to point downwards when swinging. By displaying and comparing the comparison standard and the measured data at the same time in this way, you can understand the weaknesses in your own swing.

In addition, at this time, the change in height can be expressed by using the time of impact as the origin, and by shifting the graph to represent the change before and after that point. By displaying in this way, it is possible to display the deviations from the comparison standard before and after the reference point of the motion to be compared, and provide it to the person to be diagnosed.

Next, the operation of displaying the locus of the motion point will be explained.

The coordinate position data of the operation point P stored in the memory 270 is taken, and the trajectory is stored in the graphic memo 'J 240 based on the X coordinate and the X coordinate.

At the same time, the comparison reference data is also stored in the graphic memory 240 as a locus. These two data are displayed on the display 300 via the image synthesis circuit 230. On this display 300, the locus of the motion point P in the measured swing and the locus of the comparison standard are displayed in different colors so that they can be easily seen by the person to be diagnosed.

An example of this display is shown in FIG. This example shows a change in the motion point P4 attached to the head as a trajectory, and the time point at the time of impact is displayed in bright color as a trigger at the time of impact. In the figure, T+ is the trajectory of the person to be diagnosed, and T2 is the trajectory of the comparison standard. In addition, when drawing this locus, for example, the origins of the comparison reference data and the measured data can be displayed with the origin at the time of impact or the time of address. Further, by displaying the movement trajectory before and after the trigger point, such as at the time of impact, as a trajectory in different colors, it becomes easier for the person to be diagnosed to see the motion trajectory. Furthermore, the movement point I”P of the wrist, which has a large variation in position, for example,
2. To draw a trajectory such as the operating point P1 of the club head, it is preferable to approximate the coordinates between the extracted operating points using a parabola or the like and draw the trajectory as a continuous trajectory.

As the comparison standard data, data on professional swings, one's own swing from a month ago or a week ago, or one's own practice swings can be used. This comparison standard data is stored in the IC card 121, and the ICC
The data from the card ratio output device 120 can be used manually. Conversely, the measured swing data can be stored in the IC card 121 and used for the next diagnosis.

Note that as this storage medium, a floppy disk or the like can be used in addition to the IC card.

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

In the frame memory 220, image signals are stored while updating each manually inputted frame. Then, a frame at a desired timing to be displayed, for example, an image at the time of impact, is stored in the frame memory 220 when a trigger condition is satisfied or when a sensor inputs. Furthermore, data on the locus of the motion point P is also stored in the graphic memory 240 by the above-described operation.

The CPU 260 displays the trajectory and images on the operation panel 104.
When the switch 151 is selected, the swing image stored in the frame memory 220 and the trajectory stored in the graphic memory 240 are combined and controlled to be displayed on the display 300.

This uses the image synthesis circuit 230 to synthesize two images and display them on the display 300.

An example of this display is shown in FIG. In this example, the locus of the motion point (P4) provided on the head of the person to be diagnosed is shown together with the image at the time of impact.

Next, an example will be described in which action points are displayed as stick pictures connected by line segments. Since this embodiment uses a TV screen image, there are 60 frames per second, and each image is processed one frame at a time.

Therefore, it is possible to display a stick pattern in which the movement points of the golf swing are connected by line segments for each frame and the line segments are displayed as a series of movements. By displaying only the skeleton connecting the points of this movement, the person to be diagnosed 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. When only line drawings are displayed, the storage and playback operations of the frame memory 220 may be omitted.

First, initial settings are made (331). That is, the memory 270 for storing measured values has a storage capacity of 2 seconds and 120 frames. H is after the trigger occurs (at impact)
The prohibition period setting value of the frame memory 220 is set to 180 frames (3 seconds).

In step 332, in the trigger waiting (ready) state, a line segment is drawn between the operation points P+, P2, and P3, and
Clear the screen. Further, a trigger state is displayed in step 335, and a hold state is displayed in step S40 by a lamp display.

Step 333 performs the processing shown in FIG.
The nth memory 270 for storing measured values is updated, the frame memory 220 is updated, and step 33
8 updates the n-th memory 270 in FIG. 11 and controls it to wait for the trigger state to swing.

When a trigger occurs in step S34, steps 336 to 3
By the process 9, the frame memory is updated by the number of frames updated after the trigger. Therefore, the frame at the time of the trigger is saved. Then, in step S40, a line drawing in which the motion points P, , P, , P3 of each frame are connected by line segments is displayed. Also, in step S41, the frame memory 22
The image at the time of impact, which is saved as 0, and the display of the line drawing are combined and output to the display device 300 for display.

In steps 343 to S46, when the trigger is applied, the image signal stored in the frame memory 220 is controlled to be stored for a certain period of time.

In this way, the operating point of each frame for 2 seconds)
A line drawing connecting P + to P3 with line segments is stored in the frame memory 22.
It is displayed by being combined with the image at the time of trigger stored in 0.

In addition, in the above flowchart, frame memo 1J2
Although the image signals stored in the frame memory 220 are also output at the same time, the stick pictures of the operation points P1 to P3 can be displayed except for the control part of the frame memory 220. FIG. 12 shows a display example of a stick picture in which motion points P1 to P are connected by line segments. However, in this example, the number of displayed line segments is thinned out for the sake of explanation, and all measured frames are not displayed.

By displaying line segments in this manner, it is possible to see the degree of blur caused by the swing, hollow through, etc. on a single screen.

In addition, in the operation that connects the above-mentioned operation points) P1 to P3 with a line segment, the direct operation points l''P+, P2, P3
Instead of connecting them with line segments, for example, 22 points can be taken such that 1, I XP3 P2 = P3 P2, and the line segments of P1P2 and P2P3 can be connected and displayed.

Although the operating point (P2) is provided on the wrist, it does not necessarily represent the center of bending in the swing, so the purpose is to correct the deviation.

Furthermore, in a motion that connects the motion points Pl-P3 with a line segment, for example, motion points such as at the time of impact, 45° before impact, 90° after impact, etc.)
It is preferable to obtain the coordinate values of P+ to P3 from the previous and subsequent coordinate values, display the stick picture at this point, and display the stick picture in a different color from that of the other line segments.

For a structure in which the angle to be sought or the coordinate value at the time is determined from the coordinate values of nearby measured values, please refer to Japanese Patent Application No. 1-1612.
99, and is performed by calculations such as interpolation and linear approximation.

Furthermore, FIG. 13 shows an example in which the operation diagnosis device of the present invention is made into a portable device.

This operation diagnostic device includes an imaging unit 110, a processing device 1
03, display 102, operation panel 104, printer 12
2. The speaker 126, the microphone 12B, and the ICC card specific 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. Additionally, the device includes a battery power source and is configured to operate on battery power.

When using this device, the person being diagnosed stands in a position facing this device and swings, the swing is photographed and measured by the imaging unit, and the measurement results are displayed on the display as requested. Alternatively, output it to a printer or store it in an IC card. In this example, the impact trigger timing is determined by a sensor 130 provided at a desired address position, and a start switch is provided attached to the sensor device.

Note that the trigger can be detected by satisfying the trigger condition of the operating point as described above, so it is not necessarily necessary to provide a sensor.

Since this device operates on battery power, it can be easily used at golf driving ranges where commercial power is not easily available, such as at the batting area or on the green.

Furthermore, since the operation diagnosis can also be performed on swing images captured by a VTR, it goes without saying that a VTR device can be used as the imaging unit 110 instead of a TV camera.

Here, the functions of the speaker 126 and microphone will be explained. The speaker 126 outputs a sound or a buzzer to indicate whether the trigger has been activated normally. This makes it possible to know when the measurement has ended. Furthermore, the microphone 128 can be used to issue an audio measurement start instruction instead of pressing the measurement start instruction switch.

In this case, it is necessary to provide an audio processing device.

〔Effect of the invention〕

As explained above, the present invention captures the swing of the person to be diagnosed as image data, measures this, displays the measured data together with the image at the desired swing point,
Alternatively, a stick picture of the swing can be displayed.

In addition, since it is not a large device and can easily diagnose swings, it has the advantage that it can be used for diagnosis at a golf driving range, for example, or for people's practice.
