Abstract

PROBLEM TO BE SOLVED: To enable to find or correct a defect in his/her form of exercise even if a coach person has no sufficient skillfulness, by displaying both an object for analysis and a model form and comparing both to point out differences between the object and the model form. SOLUTION: The ideal form is inputted into a personal computer before completion of this system. An exercise is photographed by a video camera 1 and the images are inputted into the personal computer 2. The images are recorded in a fixed disc as a motion picture and what is assumed as the object of the analysis is discriminated form the images. Stationary images at time intervals prescribed by sports executed by an object of the analysis are taken out. As the result, variation of the object of the analysis can be stepwisely grasped. An ideal form and the object of the analysis are displayed on a display and a defect of the object made clear by comparing with the ideal form is pointed out to suggest a correction method of the form.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exercise posture analyzing apparatus using a personal computer, and more particularly to an exercise posture analyzing apparatus using a personal computer by image processing using a pattern recognition technique.

[0002]

2. Description of the Related Art Conventionally, when checking the quality of one's own form in sports, a video recorder (VTR) is used.
And was pointed out by a coach.

[0003]

In the above-described conventional method, the first problem is that if the player does not notice the defect of his or her own form in sports, or if he wants to fix the defect, how can he correct it? Often you don't know what is good. Also, by using a VTR, you can objectively see your form,
Often cannot be identified. The reason may be that there is no person acting as a coach, or even if they do not have sufficient skills and correct knowledge, they may not notice any shortcomings or may not be able to provide an appropriate correction method.

[0004] It is an object of the present invention to provide appropriate guidance even if the coach does not have sufficient skills, or to discover his / her own defects and perform proper training without the coach. An object of the present invention is to provide an exercise posture analysis device using a personal computer.

[0005]

An exercise posture analyzing apparatus using a personal computer according to the present invention captures an image of a form to be analyzed with a video camera, inputs the captured image to a personal computer, and stops at a regular time interval. An image is extracted, a still image extracted at regular intervals is stored in a storage device, and a video of a form serving as a model to be analyzed is extracted and stored as a still image at regular intervals in the storage device, and analyzed. By displaying both the target and the example forms and comparing the two, the difference between the analysis target and the example forms is pointed out.

In addition, a drawback is pointed out as a difference between an analysis object and a model form, and a method of correcting the form is presented.

[0007]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an exercise posture analyzing apparatus using a personal computer according to the present invention.

The embodiment of the present invention is divided into a video camera (or video recorder) 1 and a personal computer (personal computer) 2 as shown in FIG. The video camera 1 inputs a video to be analyzed. The other processes, from data processing to analysis and judgment, are performed by the personal computer 2. The personal computer 2 is equipped with a video capture board for inputting an image of a video camera or a function equivalent thereto.

FIG. 2 is a diagram showing an operation of the exercise posture analyzing apparatus using the personal computer of the present invention, which is compared with an ideal form and analyzed in one embodiment of the present invention.

Referring to FIG. 2, there is shown an embodiment in which an athletics sprint is analyzed. Here, the analysis target is photographed from the side and compared with an ideal form that is a model prepared as a part of the application, and the analysis target form is analyzed.

When this system is completed, the ideal form data (images and their characteristics) for the personal computer 2 has already been input to the application.

An exercise is photographed by the video camera 1 and the image is input to the personal computer 2. The video is first recorded on the hard disk as a moving image. From the video, an object to be analyzed is identified. Then, still images are extracted at intervals determined for each sport performed by the analysis target. Thereby, the change of the analysis target can be grasped step by step.

[0014] The data is compared with the data of an ideal form from which features have been extracted in the same manner. The ideal form and the object to be analyzed are displayed on the display, and based on the analysis result, the defects found in comparison with the ideal form are pointed out, and a method for correcting the form is presented.

The identification of the analysis target from the video taken by the video camera 1 is basically performed automatically. However, analysis target cannot be identified by automatic recognition,
It is difficult to identify if several persons considered to be the target have been photographed.

Therefore, when a plurality of persons to be analyzed have been photographed, the analysis target is selected by manual operation.

A plurality of ideal form data to be compared with the object to be analyzed are prepared so that a plurality of forms can be referred to at the time of analysis. At the time of analysis, a required form is automatically selected according to the skill of the analysis target, a function to select before analysis is provided, or both functions are provided so that the user can select when necessary.

Basically, all the ideal forms are inputted into the personal computer before use, but a new form which the user of the apparatus finds to be ideal can be added.

FIG. 3 is a diagram showing the operation of the exercise posture analyzing apparatus using the personal computer of the present invention, which is compared with a bad form of the embodiment and analyzed.

As shown in FIG. 3, in addition to the comparison with the ideal form, of the some bad forms, the cases that can occur relatively frequently are converted into data, and the data are compared / searched with the analysis target to be analyzed. And, even if the most common data is compared and analyzed with the object, there is also provided a function that can grasp the defect of the own form in the same manner. This is rather suitable for classifying the shortcomings of each student when teaching a large number of students.

Depending on the sport, not only can a video taken from one side be analyzed, but also a video taken from the other can be analyzed. In the case of athletics sprinting, for example, data from front and side shots are prepared, and analysis can be performed regardless of whether the user of the device shoots from the front or side. It is.

[0022]

As described above, in the exercise posture analyzing apparatus using the personal computer of the present invention, the first effect is that even if the role of the coach does not have sufficient skills in sports, etc. You can find and fix the shortcomings of the form.

The reason is that it is difficult to notice that there is a defect in the foam. Even if a VTR is used, the drawbacks are hard to notice unless a sufficient coach points out. However, by extracting a feature from its own form by a machine and comparing it with an ideal form, it is possible to grasp the defect more objectively.

The second effect is that, when the coaching role instructs a large number of students, it becomes easier to classify students having equal skills and students who need the same practice method as compared with the related art.

The reason for this is that subjective factors are reduced in discriminating the quality of each student's form, as compared with the related art.
