JP-A-2001-265420

When assembling a relatively small part into the main body of the device, if the entire main body of the device is included in the image that will be the work instruction book, the display of important parts in the work, such as the part to be assembled and the position of the part in the main body of the device, It becomes difficult for the operator to understand.
On the other hand, if only parts important in the work such as parts to be assembled and the positions of the parts in the apparatus main body are enlarged and displayed, it is difficult to grasp which part of the entire apparatus is the assembly position, and the assembling work becomes difficult.

  Further, the present inventor has come up with the idea that the work will be easily understood if the work is displayed as a moving image. However, if you always try to display a video of the work contents during work, the video will be displayed repeatedly until the work is completed by the worker. It becomes difficult to confirm whether it is the beginning and the end.

  In view of this, the present invention is intended to make it easier for the operator to understand the work without having to stare at the screen when the work procedure is displayed by repeatedly displayed moving images. Objective.

  In the work procedure display method according to the present invention, the computer displays the work procedure for the work object as a three-dimensional CG moving image, and until the instruction to complete the display of the three-dimensional CG moving image is issued. Is a work procedure display method for automatically and repeatedly displaying the start of the work at the first part of the three-dimensional CG video showing the work procedure, and displaying the entire work object. Display an image, and subsequently zoom in on the work target part by increasing the display magnification factor continuously from the whole image so that the work target part of the work target is enlarged and displayed. In the last part of the three-dimensional CG moving image showing the procedure, a display is provided so that the operator can identify the end of the work.

  According to the present invention, a 3D CG moving image is adopted, and at the beginning of the moving image, the whole image of the work object is displayed, and subsequently, the work object is zoomed in on the work object. It is possible to grasp the enlarged work target part while grasping the whole image of the work target. Furthermore, even if a series of displays as described above is realized with a moving image and this is repeatedly displayed, the first and last portions of the 3D CG moving image are displayed so that the operator can identify them. You can easily grasp the beginning and end of the work.

The three-dimensional CG animation is a component movement display for moving a part attached to the work target from a position away from the work target to a work target attachment position after zooming in on the work target part. Is preferably performed.
In this case, since the component movement display is performed in the display of the enlarged work target part, the worker can easily understand how to install the component.

  When performing the component movement display, it is preferable to perform a display in which a character describing the component is moved along with the movement of the component. In this case, even if the component itself is displayed in a small size, the operator can grasp what the component is based on the characters that move with the component.

  At the start of displaying the 3D CG video showing the work procedure, the first image of the 3D CG video is displayed statically for a predetermined time so that the operator can identify the start of the work, and the 3 At the end of the display of the three-dimensional CG moving image, it is preferable that the last image of the three-dimensional CG image is displayed statically for a predetermined time so that the operator can identify the end of the work. In this case, the start and end of work can be easily displayed.

  When displaying a plurality of three-dimensional CG images including the component movement display, it is preferable that the display time of the component movement display is constant for each component. In this case, the moving image speed is optimized.

  It is preferable that the display angle of the 3D CG moving image is switched while the work target is displayed, and the first image of the 3D CG moving image after the display angle is switched is statically displayed for a predetermined time. In this case, the location of the work becomes easy for the operator to understand by the stillness after the angle is switched.

  It is preferable to change the color of the character explaining the components contained in the three-dimensional CG image for each type of component. In this case, even if the component is displayed small, the operator can determine the type of the component based on the color of the component description character.

  It is preferable to display the piping and wiring included in the three-dimensional CG image in different colors. In this case, the operator can easily distinguish between the piping and the wiring.

  The work procedure display system according to the present invention includes an input unit, a display unit, a storage unit that stores moving image data for displaying a work procedure on a work object as a three-dimensional CG moving image, and the moving unit from the moving unit. Display control means for reading the data and repeatedly displaying the three-dimensional CG moving image on the display unit until a display completion instruction is received by the input unit, the moving image data in the work procedure for the work object An image showing the start of work, a work start image showing the whole image of the work object, and the display magnification is continuously increased from the whole image, and the work object part of the work object is enlarged and displayed. This is data for sequentially reproducing a zoomed-in image and a work end image indicating the end of work in the work procedure for the work object.

  According to the present invention, a 3D CG moving image is adopted, and at the beginning of the moving image, the whole image of the work object is displayed, and subsequently, the work object is zoomed in on the work object. It is possible to grasp the enlarged work target part while grasping the whole image of the work target. Furthermore, even if a series of displays as described above is realized with a moving image and this is repeatedly displayed, the first and last portions of the 3D CG moving image are displayed so that the operator can identify them. You can easily grasp the beginning and end of the work.

  According to the present invention, even if the work procedure is displayed by a moving image that is repeatedly displayed, the worker can easily understand the work.

Hereinafter, an embodiment of a production management system to which a work procedure display method and a work procedure display system of the present invention are applied will be described in detail with reference to the accompanying drawings.

Then, the CPU 110a executes an application program 140a for realizing a function as a terminal in the production management system.

  The ROM 110b is configured by a mask ROM, PROM, EPROM, EEPROM, or the like, and stores a computer program executed by the CPU 110a, data used for the same, and the like.

The RAM 110c is configured by SRAM, DRAM, or the like. The RAM 110c is used to read out computer programs recorded in the ROM 110b and the hard disk 110d. Further, when these computer programs are executed, they are used as a work area of the CPU 110a.
The hard disk 110d is installed with various computer programs to be executed by the CPU 110a, such as an operating system and application programs, and data used for executing the computer programs.

  The reading device 110e is configured by a flexible disk drive, a CD-ROM drive, a DVD-ROM drive, or the like, and can read a computer program or data recorded on the portable recording medium 140. The portable recording medium 140 stores a computer program for causing the computer to function as a terminal of the production management system. The computer reads a necessary application program 140a and the like from the portable recording medium 140, and the application The program 140a and the like can be installed on the hard disk 110d.

The computer program such as the application program 140a is not only provided by the portable recording medium 140, but also from an external device that is communicably connected to the computer via an electric communication line (whether wired or wireless). It can also be provided through the telecommunications line. For example, the application program 140a and the like are stored in the hard disk of a server computer that provides an application program on the Internet, and it is possible to access the server computer, download the computer program, and install it on the hard disk 110d. It is.
The hard disk 110d is installed with an operating system that provides a graphical user interface environment such as Windows (registered trademark) manufactured and sold by Microsoft Corporation. The computer program described in the present embodiment is assumed to operate on the operating system.

The input / output interface 110f includes, for example, a serial interface such as USB, IEEE 1394, and RS-232C, a parallel interface such as SCSI, IDE, and IEEE 1284, and an analog interface including a D / A converter and an A / D converter. ing. An input device 130 including a keyboard 130a, a mouse 130b, and / or a foot lever (foot operation unit) 130b is connected to the input / output interface 110f, and the user can input to the computer by using the input device 130. Can be done.

  The hardware configuration of the server S is almost the same as the hardware configuration of the terminal device C except for the foot lever 130c.

FIG. 3 shows functional blocks of the terminal device C realized by an application program or the like.
As illustrated in FIG. 3, the terminal device C includes a work process management unit 10 and a work procedure image display unit 20. The work process management unit 10 accesses the production management database DB1 of the server S and records information regarding each work process in the production process.
In addition, the work process management unit 10 can receive input of work results and defect information from an input device such as a keyboard 130a or a mouse 130b, and can record the received information in the production management database DB1. Furthermore, the work process management unit 10 can acquire information such as an inspection result from a work target product (work target object) or an inspection device of the product by communication, and records the acquired information in the production management database DB1. be able to.

  The work procedure image display unit 20 accesses the work procedure image database DB2 of the server S, acquires an image (three-dimensional CG moving image or still image) indicating the work procedure of each work process, and displays the image on the display 120. .

  Furthermore, the production management system according to the present embodiment includes a control unit 30 for linking the work process management unit 10 that performs production management and the work procedure image display unit 20 that indicates the work procedure to the worker. .

Fig.4 (a) has shown the flow of the production process about a certain production target product. The production process includes a plurality of work processes, and each work process is a management target by the work process management unit 10.
As shown in FIG. 4B, each work process includes one or a plurality of work procedures, and a work procedure image is prepared for each work procedure. That is, one or a plurality of work procedure images are associated with each work process and stored in the work procedure image database DB2.

  One work process refers to, for example, a work of assembling a certain part A to a target product being assembled. However, the work procedure actually performed by the worker for assembling the part A is, for example, (1) mounting the part A on the target product and screwing, (2) wiring between the part A and the target product, In many cases, one work process is composed of a plurality of work procedures, such as (3) performing piping between the part A and the target product, and (4) performing inspection for operation confirmation.

  In this embodiment, a work procedure image is prepared for each work procedure. For example, for one work process of assembling the part A, (1) a work procedure image explaining how to attach the part A to the target product and screw it, (2) how to wire the part A to the target product A plurality of work procedure images are prepared: a work procedure image to explain, (3) a work procedure image that explains how to pipe the part A and the target product, and (4) a work procedure image that shows how to check for operation. Has been.

  Even if it is one work process of assembling the part A, each work procedure constituting the one work process is a different work. Therefore, it is necessary to prepare a work procedure image for each work procedure. Work becomes easier. In other words, the worker performs a corresponding work while displaying a certain work procedure image, and when the work is completed, the worker switches to the next work procedure image and performs the next work, thereby performing the determined work procedure. It can be executed steadily sequentially.

On the other hand, as production management of the present embodiment, the entire work procedures (1) to (4) for assembling the part A to the target product being assembled are handled as one work process.
If an entire work process is described with one image, many work procedures are described with one image, and the display is inappropriate for steadily executing the determined work procedures sequentially. On the other hand, in the present embodiment, since the work procedure images are sequentially displayed in units of work procedures obtained by subdividing one work process, it is easy to steadily execute predetermined work procedures.

  It is also possible to perform production management in units of work procedures corresponding to one work procedure image. However, the explanation will be given in terms of the unit of work process to be managed as production management and the image display to assist the work of the worker. The unit of the work procedure to be performed does not always coincide.

Therefore, in the production management system of the present embodiment, a plurality of work processes defined from the viewpoint of production management (for example, a part A attachment work process, a part B attachment work process, a part C attachment work process,... A plurality of work procedure images that are subdivided from the viewpoint of ease of work support for the worker are prepared for each work process.
Note that the number of work procedure images included in each work process is not constant, and the number of images can be set flexibly for each work process. Further, the number of work procedure images corresponding to one work process may be one.

5 and 6 show the flow of processing by this system. First, when a login request (input of user ID and password) is received from the worker (step S1), the system performs user authentication (step S2).
When the system is successfully authenticated (step S3), the system accepts a work instruction code (step S4). The work instruction code is a code described in a work instruction sheet distributed to each worker before work, and is used to specify a work in the production process that each worker is responsible for. The work instruction code is input from the keyboard 130a or the like.

  When the system receives the work instruction code, the control unit 30 causes the work process management unit 10 of the system to display the work process management screen D1 shown in FIG. 7 (step S5). On the work process management screen D1, a product name display part H1 to be worked, a list display part H2 of work processes, and the like are displayed.

When the operator inputs an operation start instruction for an operation process to be performed from now on using an input device such as the keyboard 130a or the foot lever 130c, and the system accepts this (step S6), the control unit 30 performs the system operation. The procedure image display unit 20 displays a work procedure image corresponding to the work process to be started on the display 120 (step S7).
The work procedure image display unit 20 acquires one or a plurality of work procedure images corresponding to the work process from the work procedure image database DB2, and sequentially displays the acquired images.

In the present embodiment, the display 120 is configured so that the work process management screen D1 and the work procedure image are switched and displayed. When the work procedure image is displayed, the work process management screen D1 becomes invisible. When the work process management screen D1 is displayed, the work procedure image becomes invisible. Thus, the work process management screen D1 and the work procedure image are switched and displayed, so that the worker can easily grasp what to do.
That is, if the work process management screen D1 is displayed, the system is in the work process management mode, and it is understood that the operator should perform a system operation (work process management process) for work process management. If an image is displayed, the system is in the work procedure display mode, and it is understood that work for production (such as assembly work) should be performed.

When a certain work process starts, the first work procedure image in the work process is displayed on the display 120. If the work procedure in a certain work process is 1 to j (see FIG. 4), a total of j work procedure images are displayed for the work process.
Specifically, the worker performs work while viewing the displayed work procedure image. When the work is completed, for example, the operator operates the foot lever (completion input unit) 130c with his / her foot to perform a completion input for ending the display of the work procedure image to the system.
In this embodiment, since completion input can be performed by foot operation, an operator can perform manual operation for performing a plurality of work procedures in one work process by performing completion input of each work procedure at any time. A series of work procedure images can be executed continuously without stopping.

When the completion input for the work procedure image other than the final work procedure image in the work process to be worked is performed (step S9), the work procedure image display unit 20 performs the work procedure corresponding to the next work procedure in the work process. An image is displayed (step S7: start of work procedure image display mode).
When the above procedure is repeated and work procedure images in the work process are sequentially displayed, and a completion input for the j-th work procedure image (final work procedure image of the work process: step S8) is received (step S10). A series of work procedure image display in the work process is terminated (step S11; end of the work procedure image display mode), and the work process management image D1 is switched and displayed instead of the work procedure image (start of the work process management mode). ).

  When the system enters the work process management mode, the work process management unit 10 receives an input of work results of the completed work process (step S12). The input of the work result may be performed by the operator inputting the numerical value (dimension etc.) of the assembly result from the keyboard 130a or the like. As a result, it may be acquired by communication, or an inspection result may be acquired as a work result by communication from an apparatus that inspects the target product.

Subsequently, the work process management unit 10 determines the acquired work result (step S13). The work process management unit 10 determines the acquired work result based on a predetermined determination criterion, and generates a determination result of pass (G) or fail (NG).
Thereafter, the work process management unit 10 performs work process management processing for registering the completion of the work process in the production management database DB1 together with the determination result (step S14). In the present embodiment, the completion information of each work process registered in the production management database includes the worker name, work process information for specifying the work process, determination result, work date, and work (completion) time. .

  When the work result is acceptable (step S15), the next work process is selected by the worker (step S17), and when the work start instruction for the work process is input (step S6), the first work process is started. The work procedure image is displayed, and the work procedure image display mode is started. Also in the next work process, work procedure images are sequentially displayed in the same manner as described above (steps S7 and S9). When the completion input for the final work procedure image in the next work process is made (step S10), the work procedure image is displayed. The display mode ends and the work process management mode is entered.

  When the work process is performed as described above and all work processes are completed (step S16), a new work instruction code can be received (step S4) to start a new work or to log out. You can also.

When the determination result of each work process is rejected (NG), when the system receives an instruction to display a defect information input screen from the operator (step S19), the work process management unit 10 displays a defect information input screen (illustrated). (Omitted) is displayed on the display 120 (step S20).
On the defect information input screen, the worker can input a defect phenomenon, a cause of defect, and the like as defect information. When the system accepts defect information input (step S21), the worker information The work information indicating the work process is registered in the production management database DB1 (step S22).

Thereafter, when failure handling completion information indicating that the handling of the failure occurring in the work process is completed is input to the system by an operator or the like (for example, clicking the “failure handling” button on the failure information input screen) ( In step S23), the work result of the work process registered in the production management database DB1 = “NG” is cleared, and the work process can be performed again (step S5).
As described above, when the work result is rejected (NG), the work process is repeated until the work is passed, so that defective products can be reduced. Moreover, since the display of the work procedure image is repeated when the work process is repeated, a reliable work can be expected.

  FIG. 8 shows a work display screen D2 for displaying a work procedure image in the work procedure image display mode. The work display screen D2 displays an image display unit H11 that displays a work procedure image, an explanatory text display unit H12 that displays explanatory text related to the displayed work procedure image, and a list that shows a list of work procedures. A list display section H13.

  In the list display portion H13, in addition to the work procedure corresponding to the work process being worked, the work procedure of the work process before and after the work process is also displayed. The work procedure (process X3 (1/6)) 50 corresponding to the work procedure image displayed on the image display unit H11 is highlighted (highlighted) on the list display unit H13, and other work procedures are displayed. Are displayed in a distinguishable manner. Thereby, the worker can easily grasp which work procedure is being executed in the series of work procedures.

In addition, it is possible to select an arbitrary work procedure from one or a plurality of work procedures corresponding to the work process in progress among the work procedures displayed in the list display portion H13. The selection operation can be performed by selecting one of the work procedures displayed on the list display portion H13 with the mouse 130b.
In the completion input by the completion input unit 130c, the work procedure image is sequentially switched in accordance with the work procedure. However, when the work is performed again, the previous work procedure image can be displayed by selecting a desired work procedure. Display flexibility.
However, since it is not possible to select a work procedure that corresponds to a work process other than the current work process, it is possible to prevent the current work process from being completed and to move to another work process, which is consistent with production management. Can keep sex.

  When the work procedure image display unit 20 displays a 3D CG moving image having a predetermined video time in the work procedure image display in step S7 of FIG. 5, until the completion input reception (steps S9 and S10) is performed. A three-dimensional CG moving image corresponding to the work procedure to be currently performed is automatically and repeatedly displayed. That is, as shown in FIG. 9, when a three-dimensional CG moving image corresponding to a certain “work procedure 1” is “moving image A1”, the work procedure is performed until completion input for the “work procedure 1” is made by the operator. The image display unit 20 repeatedly displays “moving image A1”.

  If completion input (step S9) is made as a completion instruction during the repeated display of “moving image A1”, the work procedure image display unit 20 interrupts the repeated display of moving image A1 corresponding to “work procedure 1”, and the next The repetitive display of the moving image A2 corresponding to “work procedure 2” is started.

FIGS. 10A, 10B, and 10C show video configurations of a plurality of work procedure images (three-dimensional CG moving images) included in the work process.
In the case of the work procedure image shown in FIG. 10 (a), it is composed of a START video, a zoom-in video, a component movement display video, and an END video. As the work procedure image configured as shown in FIG. 10A, for example, there is a work procedure image corresponding to the work procedure (1/6) of the process X3 indicated by reference numeral 50 in FIG. This work procedure is a work procedure for attaching the part A to the product main body, which is the work object W, with screws, and the image display unit H11 in FIG. 8 shows a START video of the work procedure image for explaining the work procedure. .

The work procedure image shown in FIG. 8 corresponds to the START in FIG. 10A and is the first part in the three-dimensional CG moving image. In the START video of FIG. 8, the entire image of the product main body that is the work target W and the “part A” P <b> 1 attached to the work target W are displayed away from the work target W. Further, in the work procedure image of FIG. 8, a screw P <b> 2 for temporarily fixing “part A” to the work object W is also displayed.
In the START video shown in FIG. 8, since the entire image of the work object W and all the parts P1 and P2 to be attached are displayed, it is easy for the worker to grasp the work object as a whole.

  Moreover, in the START video, the entire image of the work object W shown in FIG. 8 is displayed in a state of being stationary for a predetermined time (2 seconds), so that the worker has time to grasp the work object as a whole. Is secured. Furthermore, the stationary START video is the first part of the work procedure image (three-dimensional CG moving image) that is repeatedly displayed, and also has a role of allowing the operator to identify the start of the work. Here, the display time of the START video is 2 seconds. However, the display time is not limited to this, and any time may be set as long as the worker can identify the start of the work. However, if the stationary time is too long, the work efficiency is reduced and the worker must wait until the video starts. If the stationary time is too short, the worker cannot identify the work start. Can be considered. Therefore, the rest time is preferably around 2 seconds.

Further, in the vicinity of the display of “part A” P1 and screw P2, letters P-B and PR for explaining these two parts P1 and P2 are also displayed with lead lines. These characters P-B and PR have different colors. Specifically, the letter P-B describing the “component A” P1 is black, and the letter PR describing the screw P2 is red.
In this system, characters that describe parts included in an image are made different for each type of parts P1 and P2. Therefore, even when the display of the part itself in the image is small and it is difficult to determine the form of the part, it is possible to grasp the type of the part from the color of the characters describing the part.

In the work procedure image of FIG. 8, a zoom-in video is provided next to a START video that is a still video for a predetermined time (see FIG. 10A).
As shown in the order of FIGS. 11A, 11B, and 11C, the zoomed-in image shows the work target portion of the work target (part to be attached, position of the product main body to which the part is attached, or the vicinity thereof). As shown, the display enlargement magnification is continuously increased from the whole display shown in FIG.
.
The zoomed-in video after the static START video for grasping the whole makes it possible to explain in detail the work target part important for the work and facilitate the work.

  However, while the work object W and the part P1 are displayed in an enlarged manner, the characters that explain the part P1 and other explanatory characters maintain the original character size (font) regardless of zooming in. Thus, even during zooming in, visibility is improved by not changing the character size.

  During zoom-in, the parts P1 and P2 are kept away from the work object W, and the positional relationship between the work object W and the parts P1 and P2 is the same as in the STAT video. Also, the video time of the zoom-in video is 2 seconds. Although the zoom-in video display time is 2 seconds here, the display time is not limited to this, and the display time can be set as appropriate. However, if the stationary time is too long, the work efficiency is reduced and the worker has to wait until the zoom-in is completed, which is a burden on the worker. There are cases where it cannot be identified. Therefore, this display time is preferably around 2 seconds.

As shown in FIG. 10A, a component movement display image is provided next to the zoom-in image. The part moving image displays a state in which the part A displayed at a position distant from the work target W is continuously moved to the attachment position of the work target W as shown in FIGS. 12 and 13. is there. From this component movement image, the operator can easily understand how and where to mount the component A.
In addition, when moving a part, the letter P-B describing the part moves together with the part. Therefore, even if the moving part itself is displayed small, what is the part depending on the letter that moves together with the part? Can be grasped by the operator.

  The video time of the component movement display video is also 2 seconds. Further, in this system, the time interval of the component movement display video in each 3D CG moving image is set to a fixed time (2 seconds), and the moving image speed is optimized. The display time of the component movement display video may be other than 2 seconds, and the display time may be different for each component movement display video. However, if the display time is different for each part movement display video, the display time may be too long depending on the video and work efficiency may be reduced, or conversely, the display time may be too short for the operator to grasp the movement of the part. For this reason, it is preferable to display the component movement display for a certain time. Even if the parts movement display is set for a certain period of time, if the display time is too long, the work efficiency decreases and the worker must wait until the movement is completed. It is conceivable that the worker cannot grasp the movement of Therefore, this display time is preferably around 2 seconds.

Furthermore, as shown in FIG. 10A, an END video is provided after the component movement display video. This END video is the last part in the three-dimensional CG moving image of the work process X3 (1/6). As shown in FIG. 14, this END video shows a state in which the part A is attached to the work target W by the part movement video in a stationary state.
In the END video, since the state after the component A is attached is displayed in a stationary state, the operator can easily understand the state after the attachment.

  In addition, the stationary END video is the last part of the work procedure image (three-dimensional CG moving image) that is repeatedly displayed, and also has a role of allowing the operator to identify the end of the work. Note that the video time of the END video is also 2 seconds. Here, the display time of the END video is 2 seconds, but the display time is not limited to this, and any time may be set as long as the worker can identify the end of the work. The reason why the display time is preferably 2 seconds is the same as in the case of the START video display time.

  As described above, the work procedure image that is a three-dimensional CG moving image has a START video and an END video displayed in a stationary state. Therefore, as shown in FIG. 9, in one work procedure, the same work procedure is displayed. Even if the moving image indicating “” is continuously displayed repeatedly, the worker can recognize the start and end of the work in the work procedure.

  Now, FIG.10 (b) has shown the example of another image structure of the work procedure image which is a three-dimensional CG moving image. In the work procedure image of FIG. 10B, since the component movement display of two parts is performed, after “part movement display 1” (2 seconds) of a certain part, “part movement display 2” ( 2 seconds). The video time for each component movement display is the same. Other points are the same as those in the image of FIG.

FIG.10 (c) has shown another example of another image | video structure of the work procedure image which is a three-dimensional CG moving image. In the work procedure image of FIG. 10C, the display angle is switched after the zoomed-in video. When performing a component movement display by enlarging and displaying the work target part, it is preferable from the viewpoint of workability that the display angle matches the line of sight when the worker views the actual work target.
However, the appropriate display angle and the operator's line of sight are not always the same when zooming in. Therefore, by appropriately switching the angle as shown in FIG. 10C, the display angle of the image can be matched with the line of sight of the operator.

Further, even after the angle switching, the first image of the three-dimensional CG moving image after the display angle switching is statically displayed for a predetermined time (2 seconds), like the START video or the END video. By this static display, a state in which the work target part is matched with the operator's line of sight can be maintained and displayed for a predetermined time, so that the worker can easily confirm the position of the work target part after the angle switching.
Note that the display angle need not be switched after the zoomed-in video, and may be performed in other cases (for example, between the component movement display 1 and the component movement display 2 in FIG. 10B).

  FIG. 15 shows a work procedure image (three-dimensional CG moving image) different from the work procedure image described above. Note that the work procedure image in FIG. 15 is an image for explaining another work procedure (3/6) in the same work process X3 as the work procedure image described above.

In this work procedure image, the pipe L1 and the wiring (electrical wiring) L2 installed on the work target W are shown, and the routing method of the pipe L1 is displayed as a moving image while showing the positional relationship with the wiring L2.
Since the pipe L1 and the wiring L2 are represented by CG and lines, it is difficult for the operator to distinguish them. Therefore, in the present embodiment, the color of the piping (for example, blue) and the color of the wiring (for example, black) are made different so that the operator can easily distinguish between the wiring and the piping.
Note that the color of piping and wiring may be different in the work procedure image described with reference to FIG.

  Further, in the present embodiment, the configuration in which the procedure of product production work is displayed as a three-dimensional CG video has been described. However, the present invention is not limited to this, and the procedure of product repair work or product maintenance work is not limited thereto. The procedure may be displayed as a three-dimensional CG moving image. Product repair work or some maintenance work involves disassembling the product, replacing the necessary parts, and reassembling the product, such as disassembling, replacing parts, and assembling the product Will be displayed as a three-dimensional CG moving image. Further, in the product maintenance work, a work for exchanging the consumables of the product is displayed as a three-dimensional CG moving image.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible in the range which does not deviate from the summary.
