Description

The present invention relates to a motion analysis device. More specifically, according to the present invention, an image of the best form of oneself is recorded as a model motion motion, and the model motion motion image and the image of the self motion motion during practice can be simultaneously displayed on the same screen. In addition, the present invention relates to a motor-motion analysis device that allows practice to objectively approach the best state of one's own.

(Prior Art) Conventionally, as a device for analyzing a motion motion through an image,
For example, the one described in JP-A-61-111070 is known.

This golf practice video device uses three TV cameras and video devices to simultaneously shoot from the front, overhead, and back of a golfer to check the swing. The direction of movement of each video image is switched to a mirror image. By switching the image outputs so that they match on the screen by the device, the swing can be stereoscopically captured in the head of the practitioner.

(Problems to be solved by the invention) However, although this device has an advantage that the user's form viewed from three directions can be displayed on the TV screen at the same time, basically, while looking at the mirror, I can't get any suggestion about whether or not the motions are objectively good and how they compare with my own optimum motions, which is not much different from my practice.

On the other hand, movements based on sensory elements such as golf, baseball, tennis, skiing, other sports, and rehabilitation cannot be easily known by reading a book or teaching from others. It is not something you can move in the street, and in the end there is no way to be more aware of it with your own efforts and practice. Moreover, since humans have unique movement and motion characteristics that have different physiques, muscular strengths, flexibility, etc., it is necessary to practice them so that they can draw the same trajectory as other people, or to correct it to something similar to that trajectory. In particular, it can be said that it is impossible.

So these sports are usually done under the guidance of a coach, or when you get a feeling that you haven't had before because of your practice, It is a learning process in which the students practice their own motor movements in practice and make progress one step at a time.

The present inventor pays attention to this empirical fact, and records his / her optimum motor movement, which is grasped under the guidance of the coach or by the accumulation of his / her practice, as a model movement, and the model movement and the exercise at the time of practice. By comparing and analyzing the movement behavior, other people with different movement characteristics are not used as the norm,
We considered a natural, objective, and efficient learning method suitable for the body shape or exercise characteristics of the individual.

Therefore, an object of the present invention is to provide a motion-motion analysis device capable of comparing and analyzing the current motion motion based on its own optimum motion motion.

(Means for Solving the Problems) In order to achieve such an object, the motion analysis apparatus of the present invention stores an image pickup means for picking up an image of a subject including a subject of exercise and image information picked up by this image pickup means. In addition, the image storage means that stores the motion movement considered to be optimal for the exercise subject as the model motion motion and the model motion motion comparison motion motion stored in the image storage means are stored in the R of the RGB signal circuit.
Image signal control means for processing the image signals so as to be simultaneously displayed as images of different single colors using two or two combinations of signals, G signals and B signals;
It is composed of image display means for displaying the image information output from the image signal control means.

(Operation) Therefore, the model motion motion obtained under the guidance of the coach or by accumulating his / her practice and the current comparative motion motion at the time of practice are simultaneously displayed on one screen of the image display means. With this, it is possible to practice while comparing the current self-movement motion and the self-exercise movement motion on the screen. Moreover, since only the part different from the optimum motion of the user is displayed in a different color from the other parts, it is possible to easily and instantly discriminate.

(Example) Hereinafter, the structure of the present invention will be described in detail based on an example shown in the drawings.

FIG. 1 is a block diagram showing an embodiment of the motion analysis apparatus according to the present invention. In the figure, a tee 2 is installed at a fixed position on the tee ground 1, and a golf ball 3 is placed on the tee 2. In addition, the tee ground 1 is an exercise subject performing a tee shot, which is an exercise action,
That is, the golf player 4 stands in a fixed positional relationship with the tee 2. The tee 2, the golf ball 3, and the golf player 4 form a subject, and an image is picked up by a television camera 5 which is an image pickup means. The image signal of the subject imaged by the television camera 5 is sent to the image signal control means 6 and is subjected to a certain process to be a memory 7 as a storage means.
Alternatively, it is sent to the CRT display 8 which is an image display means.

The CRT display 8 is installed so as to be embedded in the tee ground so that the golfer 4 can enter the field of view without moving the head when the golfer 4 is in the tee shot position. Further, as shown in FIG. 4, the CRT display 8 may be completely buried under the tee ground 1 so that the golfer 4 on the tee ground 1 can see a specular reflection image through the mirror 81. In this case, the image output to the CRT display 8 is a normal image, and the image signal control means 6 does not need the processing unit 68 for converting the image signal into a mirror image. still,
Reference numeral 82 is a transparent window.

The image signal control means 6 sends an image signal sent from the television camera 5 in accordance with an instruction signal given by a controller 9 installed at a position where a third party or the golfer 4 on the tee ground 1 can operate. And the image of the subject is stored in the memory 7, and the model motion image (the image of the optimum motion created by the coach's instruction, etc.) stored in advance in the memory 7 and the image currently captured by the television camera 5. C or the comparative movement motion image (the image of the current movement motion to be compared) stored in the memory 7 at the same time.
It is displayed on the RT display 8. For example, the image signal of the model motion and the image signal of the comparative motion are alternately output every other scanning line by using a known computer image processing technique to simultaneously generate the model motion image and the comparative motion image at the same time. It is displayed on the CRT display 8. In this case, the model motion motion and the comparative motion motion are output as images that are independent of each other. Further, the model movement motion image signal and the comparison movement motion image signal are simultaneously output using two or two sets of RGB signal circuits, and the model movement motion and the comparison movement motion are displayed in different color images. The overlapping portion, that is, the portion where the operation is the same, can be displayed in a color synthesized by the additive color mixture. For example, if the model motion motion image signal is output using the R signal circuit and the comparative motion motion image signal is output using the G signal circuit, the model motion motion is a red image and the comparison motion motion is a green image. The part that is doing is displayed as a yellow image. In this case, the closer the model motion and the comparative motion are to each other, the more the image is displayed as a single color.

The television camera 5 is installed so that the tee 2 is at a fixed position on the screen of the CRT display as shown in FIG. That is, the position on which the tee 2 is placed serves as the reference position of the subject, and the reference position is installed so as to be displayed at a fixed position on the CRT display 8. As a result, the golfer 4
When the image stored in the memory 7 and the image currently taken by the television camera 5 are simultaneously displayed on the screen of the CRT display as long as the player stands in a fixed positional relationship with the tee 2. , If the address position, swing form, rhythm, etc. of the golfer 4 are the same as the optimum exercise motion, the images are displayed in an overlapping manner,
If they are different, the images are shifted and displayed twice.

Further, the image signal control means 6 performs image conversion on the image signal picked up by the television camera 5 and sends the mirror image signal to the CRT display 8 and the image signal from the memory 7. Has image signal processing means for sending a processed image signal to the CRT display so that the image is reproduced at a reproduction speed according to a command from the controller 9 by performing a certain process.

FIG. 3 is a block diagram showing a detailed configuration of the image signal control means 6, and an analog image signal from the television camera 5 is analogized through a camera control unit (CCU) 61 which performs various controls such as input brightness adjustment. It is sent to the digital converter (A / D) 62 and converted into a digital signal, and this digital signal is sent to the input / output device (I / O) 63. The input / output device 63 is the controller 9
Controlled by a central processing unit (CPU) operated by, the digital image signal is temporarily stored in a buffer (BUFFER) 65 and stored in the memory 7, or the image signal stored in the memory 7. And the image signal currently being imaged together through the digital-analog converter (D / A) 66.
Send to. At this time, the signal from the memory 7 is controlled in reproduction speed based on the instruction of the central processing unit according to the processing procedure stored in the image signal processing means (ROM 1) 67, and at the same time, as a mirror image forming means. In accordance with the image signal conversion procedure stored in the image signal converting means (ROM 2) 68, the image signal is converted into a mirror image signal and sent to the digital-analog converter 66. In addition,
The camera control unit 61, the analog-digital converter 62, the input / output device 63, the buffer 65, etc. are synchronized by a synchronization signal generator 69.

According to the above configuration, a desired image of the subject captured by the television camera 5 can be stored in the memory 7, and a mirror image of the stored image and the currently captured image can be stored in the golfer 4. CR installed in the field of view
The images can be displayed on the screen of the T display in an overlapping manner at the same time, and the stored image can be reproduced at an arbitrary reproduction speed. Thus, if the memory 7 stores the motion of the self's nice shot, which is the model motion of the self, the user can practice while comparing the motion of the self's nice shot with the current motion of the self's shot on the screen. It enables you to learn in a natural and natural way that suits your individual body shape and exercise personality.

Although the image signal converting means 68 is used as the mirror surface image forming means in the above-described embodiment, it is also possible to take an image of a subject with a mirror and take an image of the mirror with the image taking means. Of course.

Further, in the above-mentioned embodiment, the example in which the present invention is applied to the exercise motion of golf has been described, but the present invention is not limited to this, and can be applied to, for example, baseball, tennis, ski and other exercise motions. .

(Effects of the Invention) As is apparent from the above description, the motion-motion analysis device of the present invention is configured such that an image of a model motion motion of oneself and an image of a motion motion currently being performed are different in color on the same screen. Since it is displayed at the same time as the above, only the part that is different from one's own optimum motion motion is displayed in a different color from other parts, and the difference from the one's optimum motion motion is indicated by the color. The amount of displacement, etc., can be instantly and easily determined.
Therefore, it is possible to acquire effective motor movements in a natural and natural manner by approaching them based on the best motor movements of oneself.
