SOLUTION: More than two pattern animations shooting series of motions composed of a plurality of motion elements are saved respectively in image recording media. More than one of pattern animations are defined as a master animation and the others as slave animations. Each image recording media is replayed and these images are examined, then a slave animation is edited by replying forward/backward with variable speed so that the rating value with nominal action elements of the master animation becomes to be 1.0, then the standard animation of the series of motions is finally made. The motions that the standard has not been clear can be provided with the visually understandable standard animations to every one.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the technical training of factories.
Improvement and guidance, optimization of sports training and handicrafts,
The present invention relates to a motion analysis method for creating a reference moving image in a motion such as a craft in which an expert and a beginner have large variations.

[0002]

2. Description of the Related Art [Actual situation in the industrial world] In an industrial production line, a method of performing a motion analysis using the concept of rating is widely used. A series of motions (motions) performed by the operator are recorded on a video or the like, and the operator measures the work motion with a stopwatch as necessary while reproducing the video. Further, if the person is a person, the invalid time is measured, the net time is further obtained, and the standard work time is calculated. For example,
Consider the case where "sewing work by sewing machine" is included in an industrial production line. The work performed by the worker is recorded as a video, and the motion is analyzed while reproducing the moving image. The operation described here as an example includes the following operation elements (see also FIG. 3). No.1 <Remove the fabric and set it on the sewing machine stand> No.2 <Sew> No.3 <Align the fabric> No.4 <Sewing> No.5 <Place the fabric on the table> Play the video and display the screen. While watching, observe the first operation element, until the worker takes the dough and sets it on the sewing machine stand,
The time from the beginning to the end of the work is measured with a stopwatch and recorded in a record table. At this time, if an invalid operation that is impossible, wasteful or uneven is found, the moving image is stopped, and only the invalid operation is measured and described. Similarly, for the next operation element No. 2 <sewing>, from the beginning to the end of the operation and the invalid operation are measured with a stopwatch, and are recorded in a record table. This measurement is performed up to No. 5 <Place the dough on the table>, and a record table is created. After that, the net time, the invalid time, and the like for each item of the operation element are written in a worksheet of a spreadsheet software and stored together with the video. The work pace is estimated based on these data, and the rating value is set. Assuming that the standard pace is 1.0, it can be certified that if it is faster than that value, it will be larger, if it is slower it will be smaller. Further, in a training course for newcomer education or a training course for technical improvement, etc., a skilled person refers to the worksheet and explains tips and notes on work while showing the recorded video to the trainee. In addition, researches on higher working efficiency by recording the actions of a skilled person and an inexperienced beginner and playing back the two videos simultaneously have been conducted.

[Situation in the sports world] [0003] In the sports world, for example, in individual sports such as swimming, beginners learn how to move their hands and feet by taking a video of a skilled swimmer. Have been done. Furthermore, in golf competitions, simultaneous playback of a video medium recording the manner of swinging of a skilled player and a beginner, and imitating the movement of a skilled player, and actually correcting the movement of a beginner, are for general use. This is common in golf classes. Also, in team sports such as baseball, a video camera is installed at each of a plurality of positions to record the progress of the match, and the images are played back simultaneously, and the coach instructs the players in cooperative play. This is common in amateur organizations. With the widespread use of video equipment, simulation learning in such educational sites has been frequently performed. In addition, in terms of appropriate speed of operation, the above-described rating method in the industry can be sufficiently applied.

[0004]

One of the problems of education in the industrial or sports world is that standard standards are not clear. Speaking of factory work, if seven workers were 68, 70, 72, 67, 66, 73, 80, respectively, the average hourly speed 70 would easily be the standard / standard. Can be calculated. However, in the case of actual work, for example, in the case of the sewing machine of the previous example, from the operation of No. 4 <sewing> to the timing of No. 5 <put the cloth on the table>
It is not possible to calculate numerically how best to perform such an operation, or how fast the fabric can be moved to achieve beautiful sewing. It is necessary to have standards and standards that can be visually recognized by all. In addition, regarding the rating value 1.0 described above, the measurer (IE man)
Is determined by the experience of For the workers, the rating values of 0.8 and 1.2 cannot be perceived intuitively and are very real.

[0005] The second problem is that it is difficult to save and utilize the data for motion analysis. The recorded video,
The record of the net time of the operation element and the record of the tips and precautions on the operation are separately stored. Further, in this case, it is difficult to cut and edit the invalid operation, and it is troublesome to save the state as a moving image. With the spread of high-performance personal computers, it is possible to input them as data. However, this does not mean that they need only be input to a computer and saved, and software that introduces the concept of rating is necessary for effective use after saving.

A third problem is that when a plurality of motion analyzes are performed, the operation is very troublesome. In any of the above-described examples, if the series of operations is a plurality of patterns, the motion of the video medium on which the moving image has been recorded must be analyzed a plurality of times. Further, when comparing the plurality of patterns, it is not easy to start a plurality of video media simultaneously with a plurality of playback devices (coincide the movements) when reproducing. Devices for synchronization have been developed,
It is very expensive and requires special operation techniques when used, which is of course unsuitable for general factories and educational sites. It is very convenient if even a plurality of patterns of motion analysis can be operated on the same system. The purpose of the present invention is
An object of the present invention is to solve the above problems and provide a motion analysis method suitable for technical education, improvement, guidance, sports training, and the like, which can be easily used by anyone.

[0007]

In order to achieve the above object,
The motion analysis method according to the present invention saves a moving image obtained by capturing a series of motions composed of a plurality of motion elements in an image recording medium, reproduces the image recording medium, and refers to the screen,
Defining and defining each of the operation elements, storing the information in a recording medium, and measuring the time between invalid operation including excessive, wasteful or uneven operation of the operation element and other net operation, and measuring the information. Register in the recording medium, skip or delete the invalid operation screen, save the information in the information recording medium, the moving image at a variable speed so that the net operation time rating value of the series of operations is 1.0. It is characterized by performing forward / backward reproduction and editing to create a moving image that is a reference for the series of operations.

In the motion analysis method according to the present invention, two or more pattern moving images obtained by imaging a series of operations constituted by a plurality of operation elements are respectively stored in an image recording medium, and one of the plurality of pattern moving images is stored. One or more as a master moving image, the other as a slave moving image, playing back the recording medium, referencing those screens, defining and defining each of the operation elements of each of the pattern moving images, and defining the information. Save the information on the information recording medium, measure the time of the invalid operation including the excessive, wasteful or uneven operation of the operation element and the time of the other net operation, register the time on the information recording medium, and skip the invalid operation screen or Delete the information, save the information on the information recording medium, and after the above work, copy the plurality of pattern moving images from the start screen or for each operation element. It reproduced again by the combined net operations of elements of the master video, rating value
Send the slave video at a variable speed so that it becomes 1.0
It is characterized by performing reverse playback and editing to create a moving image as a reference for the series of operations.

Furthermore, in the motion analysis method according to the present invention, a series of motions composed of a plurality of motion elements according to the present invention is used to capture two or more pattern moving images of the same motion from two or more directions or portions. A moving image serving as a reference for the series of operations. In addition, in the motion analysis method according to the present invention, for a motion element of a series of motions composed of a plurality of motion elements, importance and points to be considered technically in the series of motions, etc. Can be associated with the comment field, and can be referred to when viewing the operation element.

“a” and “b” are operation analysis result tables displaying analysis results in a table format. Represents an operation element, and up to 999 operation elements can be analyzed in one cycle. The operation element name can be registered by inputting from a keyboard or calling an operation element pickup screen (not shown). in this case,
Since the sewing operation is performed, <take out the cloth / set on the sewing machine stand>, <sewing>, and the like are input. R is a selection of whether or not there is a rating effect at the time of reproduction. When reproducing in the rating reproduction mode at the time of analysis reproduction, it is selected whether or not to reproduce by estimating a reproduction speed from a rating value for each operation element. I do. The start time indicates the position of the moving image at the start of the analysis, and the element time indicates the time of the operation element, ie, the net operation time + invalid operation time, and the net operation time indicates the time excluding the invalid operation time, ie, the actual operation time The invalid operation time represents the total time when an invalid operation is found. Numerals 18a and 18b are display columns for inputting and displaying a rating value of the current cycle, and calculating and displaying a standard time from the rating value by switching ("rating value 1.00 = rating coefficient 100%").
Means Accordingly, the indications of 18a and 18b are shown as a rating coefficient of 85% and a rating coefficient of 140% in FIG. 2, but the display can be changed to a rating value of 0.85 or a rating value of 1.4 as desired.) . Reference numeral 20 denotes a selection field for a display unit of time,
You can switch between DM, which divides one minute by 100, and SEC, which divides one minute by 60. Reference numeral 21 denotes a moving image designation button. Top designates the beginning of the operation element, and End designates the end of the operation element. Video display screen 1
This operation can be performed by clicking and designating either 1a or 1b, or can be performed by synchronizing both screens. 2
Reference numeral 2 denotes a two-screen control ratio setting button. When zero is pressed, the operation of the specified moving image becomes zero, and when Pos is pressed, 1 is displayed.
The difference in cycle speed is displayed in the display column 23.

A procedure for performing a motion analysis using these functions will be described. First, the movie A which is the master screen
Is analyzed. First, in order to find the analysis start position, the PLAY button of the moving image control button 15 is clicked to display a moving image on the moving image display screen 11a, and the image is sent to the analysis start position. In this operation, the user clicks the STOP button to stop the moving image on the moving image display screen 11a, and clicks the BACK button to return the moving image. The slider 13 indicates how much the moving image progresses with respect to the whole. Also, by operating the knob of the slider 13,
You can fast forward and rewind a video.

After the start position of the analysis start is determined in this manner, the moving picture screen on the moving picture display screen 11a is clicked to start the moving picture analysis. The analysis can be disclosed in any state during operation or while stopped, and when the moving image is stopped, the moving image is reproduced and displayed. This position is recorded as the start time of the operation element No. 1. If the user overlooks the moving image during the analysis and wants to return to the analysis start position, click the Top of the moving image designation button to return the moving image to the start position and play it back.

When the position at which the analysis of the motion elements is completed is reached, the reproduction of the moving image is stopped by clicking the moving image screen on the moving image display screen 11a again.
The position up to this position is recorded as one operation element. As for the analysis time, it is possible to analyze at least 0.5 DM (0.3 SEC) for one operation element. Switching to (DM) or (SEC) is performed by the switching button 20. The operation element whose analysis has been completed is clicked on the operation element in the operation analysis result table 17a, a cursor is displayed, and the element name is key-input, whereby the operation element name is registered. In this case, it is also possible to call an operation element pickup screen (not shown) and click a corresponding operation element to register a character operation element name.

Next, a selection operation of "with" or "without" of the rating effect is performed on the motion element whose motion has been analyzed. Accordingly, when the analysis result is reproduced in the rating reproduction mode, the moving image is reproduced at a speed calculated from the set rating value and the selected reproduction speed. In this case, “Yes” or “No” for this calculation is selected for each motion element, and this speed does not need to be calculated for a moving image element having a constant speed. In that case, “No” may be selected. .

The setting of the type of the operation element is executed by selecting the corresponding operation element type number in the operation type display field 17a or clicking and inputting the type name.

By clicking the moving picture screen on the moving picture display screen 11a again, the analysis of the next operation element can be started, and the analysis of the operation element No. 2 is started. If the scene does not need to be analyzed, click the PLAY button to search for the analysis start position. In this case, it is possible to return to the initial position by clicking Top of the moving image designation button.

If an invalid operation such as excessive, waste, or unevenness is found during the operation analysis, the reproduction is stopped by right-clicking the moving image screen on the moving image display screen 11a, and the invalid time is measured. You can start. The measurement of the invalid operation is started by left-clicking the moving image screen on the moving image display screen 11a or clicking the PLAY button, and is ended by clicking the moving image screen on the moving image display screen 11a either left or right. be able to. In this case, the moving image on the moving image display screen 11a does not stop, and returns to the normal analysis. Thus, in the measurement of the invalid operation, the time from clicking the moving image screen on the moving image display screen 11a to clicking again is measured as the invalid time. If necessary, you can also register this invalid count

If there is no invalid operation during the execution of the motion analysis, the top of the moving image designation button is clicked,
The moving image screen can be returned to the start time position of the operation element. On the other hand, when there is an invalid operation during the execution of the motion analysis, the moving image screen can be returned to the end position of the final invalid operation by clicking End of the moving image designation button 21.

To set the letting value, click on the letting value display field 18a to display a cursor, for example, 50
By key input within the range of 200%, the total operation time and the standard time calculated from the rating value are displayed, and this rating value can be changed even during analysis reproduction.

When the above operations are completed, all operations are stored in the storage unit 104 by performing a save operation, and a new operation can be performed. Thus, the motion analysis of the master moving image A alone is completed. The slave moving image B may be displayed on the moving image display screen 11b and performed in the same manner as the moving image analysis on the moving image display screen 11a described above. Next, a description will be given of a marker operation field 30 for adjusting the start of an operation element. The button at the top of the operation column has a function of editing, and includes a selection button 31 for selecting an operation element of a moving image from the left, a registration button 32 for registration, and a delete button 33 for deleting the registered one. The display field 34 is a place for indicating the number of the activated operation element. When the marker operation field 30 is first called, the mode is set to match the movement. Movie display screen 11
In a and 11b, the numbers of the operation elements to be registered are displayed in the display column 30 in the playback state. When the screen to be registered is reproduced, the mouse is dragged to the selection button 31 while clicking on the screen 11a, and the button 31 is clicked. Then, the element of the screen 11a being reproduced is marked and saved. Similarly, the same operation is performed on the screen 11b. At this time, the start and end of the moving image element are displayed in display fields 35a and b and 36a and b.
In the case of comparing two or more screens, which will be described below, if the number of the operation element to be compared is input in the number display field, the moving image display screen wakes up to the moving image of the operation element to see which operation element is being reproduced. Can be displayed.

Next, the operation analysis for creating a reference moving image by comparing the master screen and the slave screen will be described.
At first, the number of the operation element to be compared is displayed in the operation element display section 34 of the marker operation section 30 in order to match the movement. As an example, the master moving image A, that is, the moving image display screen 11a, and the slave moving image B, that is, the moving image display screen 11b, are both reproduced at 100% speed (operation of the moving image speed adjustment section 16). The reproduction mode switching buttons 13a and 13b designate "ALL EVENT". Press Top of the video specification button 21 and press N
Specify the first position of o.1 and press the operation control button 15
Press PLAY. Thereafter, editing is performed while comparing the operation display screens 11a and 11b. Probably, it can be seen that the master moving image A has less invalid operation than the slave moving image B. At this time, the master of the master moving image A should be more aware of how to grasp the cloth, place the cloth on the sewing machine table, and the like than the beginner of the slave screen B. 2
Comment screen (not shown) that can be judged from two screens
Is called from the toolbar and written there. These are not just comments, but can be technical and educational materials.

It seems that a beginner also has a disadvantage that the operation is simply slow. In that case, the moving image display screen 11
When the speed b is increased at a speed of 101% to 110% for each width 1%, the progress of the beginner can be simulated. Alternatively, the speed of the moving image display screen 11a is set to 99 to 90.
Even if the reproduction is performed at a reduced speed every 1% of the range of%, it is possible to simulate the state before the skilled person acquired the current technology. The important point here is that the speed can be adjusted by visually recognizing an appropriate operation while watching the moving image display screens 11a and 11b, rather than simply being able to numerically raise and lower the speed. With this operation, a new rating can be set. That is, a person who is familiar with the rating of the work can simulate the speed, which is about the standard speed, and replace it with an appropriate numerical value to create a more appropriate standard / standard. be able to. The rating value is displayed in the display column 18a,
b and can be registered.

Also, the same speed set as described above does not always apply to all operating elements. For example, if the operation element is No. 2 <sewing>, the variable speed of the sewing machine should have an upper limit and a lower limit. It does not mean that only the movement of the worker should be made faster. No.2 Operating element specific standards and standards should be set. Then, press the Top of the video designation button 21 again, synchronize from the first position of No.2, simulate two screens,
Set an appropriate speed.

Furthermore, it is conceivable that a skilled person has very few invalid operations, and in some cases it is equivalent to none. Therefore, in order to bring the operation of a beginner closer to the operation of an expert, the playback mode switching button 13a is set to "ALL EVENT" and 13b is set to "CU
As a result, it is possible to simulate the operation of a beginner so that there is no invalid operation. Since the moving image display screen 11a, which is the master moving image, is also reproduced at the same time, it is possible to compare and see the moving image display screen 11a. In addition, this comparison screen was a comparison between an expert and a beginner.
However, this system can simulate the highest speed technology, which can be called the operation of a senior expert or a super expert. Slave movie B is set to 12
Set the master screen to 0% and increase the speed of ordinary workers by 150%
If they are reproduced and compared, and the reference moving image is created as described above, a considerably high rating setting can be made.
It is possible to visually understand a worker who can perform highly skilled work even if a worker who exceeds the normal speed is not actually present at the site. This cannot be achieved without this system. Furthermore, training of a measurer (IE man), ie, a technician who certifies the rating, is also possible with the present system. It is said that it takes six months or one year to train this type of technician, but it can be acquired in a few days or as fast as one day. In addition, as described above, since learning is performed by a simulation of a super-skilled person, highly accurate rating can be performed. This is similar to the fact that the frequency of seeing good paintings can improve the distinction between good and bad, and advanced skills can be acquired by repeatedly viewing advanced techniques as teaching materials. Possibilities can be increased.

According to this embodiment, a comparison between an expert and a beginner can be visually simulated. In addition, it is possible to reproduce and save work operation standards and standards that were not clear only by numerical values until now. In addition, it is possible to simulate the operation of a super-skilled person who is not actually at the site. If this system is used, it can be projected on a large screen, such as a projector, to hold an educational seminar, and an operator can learn by himself / herself on a personal computer. In particular, in the latter case, it is possible to call out comments as appropriate and learn the importance and precautions of the operation element, the frequency of one-to-one training by skilled workers is reduced, and the skilled worker is You can concentrate.
It is also useful for training qualified technicians.

If the present embodiment system is used in a factory or a work place, the ability of each individual can be accurately evaluated, and the ability can be paid accordingly. As a result, it can be used not only for technical education but also as a tool for labor management and personnel management.

The above-described embodiment describes an example of the sewing operation in the industrial world. However, the present invention is not limited to this and can be applied to a sports site. For example, in a game of individual play such as golf, using the concept of rating, a moving image of an advanced player and a beginner is stored, an operation element is defined, and the time of a net operation / ineffective operation is measured. After that, the above-described simulation is performed to create standard / standard operations. It can be used as teaching material for amateur sports classes. Of course, it is also possible to simulate not only amateurs but also the tops of professional sports and use them to study higher skills. Further, in a team game such as baseball, a plurality of moving images are recorded for each position, and the moving images are played back together to perform a visual simulation. Here, the action of the pitcher is defined as the master moving picture, and the moving picture of the catcher and the outfielder is defined as the slave moving picture, and the other players can learn their own actions according to the movement of the pitcher. Here, the operation element changes for each moving image, but the system of the present embodiment can cope with such a setting without any problem. This is also the result of applying some kind of rating concept.

A moving image obtained by capturing a series of operations composed of a plurality of operation elements is stored in an image recording medium, the image recording medium is reproduced, and each of the operation elements is defined by referring to a screen thereof. Make a definition, save the information in the information recording medium, measure the time of the invalid operation including the excessive, wasteful or uneven operation of the operation element and the other net operation, and register it in the information recording medium. Skip or delete the invalid operation screen, save the information in the information recording medium, the net operation time rating value of the series of operations is 1.0
A motion analysis method, wherein the moving image is edited by performing forward / backward reproduction at a variable speed so as to generate a moving image which is a reference for the series of operations. 2. A method according to claim 1, wherein two or more pattern moving images obtained by imaging a series of operations constituted by a plurality of operation elements are respectively stored in an image recording medium, and at least one of the plurality of pattern moving images is set as a master moving image. Others are defined as slave moving images, each of the image recording media is reproduced, the screens are referred to, the operating elements of each of the pattern moving images are defined and defined, and the information is stored in the information recording medium. The operation element is impossible, the invalid operation including wasteful or uneven operation and the time of the other net operation are measured and registered in the information recording medium, the invalid operation screen is skipped or deleted, and the information is deleted. After the work is completed, the plurality of pattern moving images are reproduced again from a start screen or in synchronization with each operation element. -In accordance with the net operation of the motion element of the moving image, the slave moving image is edited by performing forward / backward playback at a variable speed so that the rating value becomes 1.0, and creating a moving image that is a reference of the series of operations.
