It includes a type 3D scanner 320, a display device 330, and an input device 340.

The data server unit 200 has an HDD (Hard Disk Drive) and stores a three-dimensional model created by the three-dimensional model creating device 100 and various data necessary for creating the three-dimensional model. Specifically, the data server unit 200 is required to assemble the product, the verification procedure manual DB 210 for storing the data related to the verification procedure manual for the design review, and the component DB 220 for storing the data related to the parts constituting the product. A jig / tool DB 230 that stores data related to various jigs and tools, a work center DB 240 that stores data related to work centers such as product installation sites, locations, and factories, and a two-dimensional model of parts, jigs and tools, and work centers. The 2D model DB250 and the 3D model DB260, which store the three-dimensional models, respectively, are stored. In the following description, parts, jigs and tools, and work centers are collectively referred to as objects.

The verification procedure manual DB 210 stores the verification procedure manual data related to the verification procedure manual that records the verification procedure of the design review. Specifically, as shown in FIG. 2A, the verification procedure manual DB 210 stores the title name (DR name) of the verification procedure manual of the design review and the verification procedure manual ID which is the ID of the verification procedure manual as header information. Further, the verification procedure manual DB 210 is required for the verification item name, the verification item ID which is the ID of the verification item, and the verification work in the verification item for each verification item for which the design review is performed in association with the header information. The ID (part ID, jig / tool ID, work center ID) of the object (part, jig / tool, work center) and the result of the verification work in the verification item, the performer, the implementation date, etc. are stored in association with each other. The verification procedure manual DB 210 is an example of the verification procedure manual storage unit of the present invention.

The component DB 220 stores data related to components included in the product. Specifically, as shown in FIG. 2B, the component DB 220 includes a component ID which is an ID indicating a component, a name of the component, and actual data indicating the actual characteristics of the component (captured image, dimension, material of the component, It is stored in association with the storage location, etc.).

The jig / tool DB 230 stores data related to the jig / tool required for assembling the product. Specifically, as shown in FIG. 2C, the jig / tool DB 230 contains a jig / tool ID which is an ID indicating the jig / tool, a name of the jig / tool, and actual data (capture of the jig / tool) indicating the actual characteristics of the jig / tool. Images, dimensions, materials, storage locations, etc.) are stored in association with each other. A record without physical data means that the corresponding object is out of stock and the physical object is not at hand.

The work center DB 240 stores data related to the work center, which is a product installation site or the like. Specifically, as shown in FIG. 3A, the work center DB 240 has a work center ID which is an ID indicating the work center, a name of the work center, and actual data (capture of the work center) indicating the actual characteristics of the work center. Images, dimensions, materials, etc.) are stored in association with each other.

The component DB 220, the jig tool DB 230, and the work center DB 240 are examples of the physical storage unit of the present invention.

The 2D model DB 250 stores a two-dimensional model of an object. Specifically, as shown in FIG. 3B, the 2D model DB 250 has an ID that is one of a part ID, a jig tool ID, and a work center ID, and a drawing number of the part, the jig tool, or the work center indicated by the ID. And the two-dimensional model of the part, jig, or work center associated with the drawing number and the attribute information (name, size, etc.) of the two-dimensional model are stored in association with each other. The 2D model DB 250 is an example of the two-dimensional model storage unit of the present invention.

The 3D model DB 260 stores a three-dimensional model of an object required for design review verification work. Specifically, as shown in FIG. 3C, the 3D model DB 260 is a diagram of an ID that is one of a part ID, a jig tool ID, and a work center ID, and a part, a jig tool, or a work center corresponding to the ID. The number is stored in association with the 3D model of the part, jig, or work center associated with the drawing number and the attribute information (name, size, etc.) of the 3D model. The 3D model stored in the 3D model DB 260 may be one created by a 3D CAD system or may be created by 3D scanning the actual product with a 3D scanner. The 3D model DB 260 is an example of the three-dimensional model storage unit of the present invention.

Returning to FIG. 1, the communication unit 300 accesses the data server unit 200 via the communication line, calls the data stored in the data server unit 200, and transmits the data to the data server unit 200. The communication line is not limited as long as it can access the data server unit 200, and may be an internal bus that accesses the data server unit 200 arranged inside the three-dimensional model creation device 100, or may be an internal bus arranged outside. It may be an internet line that accesses 200. For example, the communication unit 300 outputs the design review verification procedure manual, the three-dimensional model, the two-dimensional model, and the actual data called from the data server unit 200 to the control unit 400. Further, the communication unit 300 transmits the verification procedure manual and the three-dimensional model output from the control unit 400 to the data server unit 200.

The handy 3D scanner 310 is a user-portable three-dimensional scanner. The handy 3D scanner 310 creates a three-dimensional model of the target object and outputs it to the control unit 400. The handy 3D scanner 310 is suitable for creating a three-dimensional model of a relatively small object.

The stationary 3D scanner 320 is a large three-dimensional scanner that cannot be carried by the user. The stationary 3D scanner 320 creates a three-dimensional model of the target object and outputs it to the control unit 400. The stationary 3D scanner 320 is suitable for creating a three-dimensional model of a relatively large object.

The display device 330 is an LCD (Liquid Crystal Display) and displays various screens under the control of the control unit 400. The display device 330 may be a head mount.

The input device 340 is a mouse, a keyboard, or the like, and receives an operation from the user, and outputs a signal corresponding to the received operation to the control unit 400.

The control unit 400 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The control unit 400 controls each unit of the three-dimensional creation device by having the CPU read the program stored in the ROM and execute it on the RAM. Further, the control unit 400 includes a menu control unit 410, a necessary object determination unit 420, a three-dimensional model creation unit 430, and a preview display unit 440 as functional configurations.

The menu control unit 410 calls, selects, and edits data from the verification procedure manual DB210, parts DB220, jig tool DB230, and work center DB240.

The required object determination unit 420 determines objects (parts, jigs and tools, work centers) required for product design review based on the verification procedure data.

The 3D model creation unit 430 confirms the presence or absence of a 3D model of the object determined by the required object determination unit 420, and performs a process for creating a 3D model of an object that has not been created (model uncreated object). ..

For example, when there is a two-dimensional model of an unmodeled object, the three-dimensional model creation unit 430 performs a process for creating a three-dimensional model of the unmodeled object from the two-dimensional model.

Further, when there is no 2D model of the model-uncreated object, the 3D model creation unit 430 identifies a similar object from the actual data of the model-uncreated object, and performs a process for diverting the 3D model of the similar object. ..

Further, when the similar object cannot be identified, the three-dimensional model creation unit 430 determines a three-dimensional scanner suitable for three-dimensional scanning of the actual object for which the model has not been created, and the determined three-dimensional scanner does not model. Performs a process for instructing the user to scan the actual created object in three dimensions.

The preview display unit 440 combines a three-dimensional model of each object necessary for the verification work of the design review and displays it on the display device 330.

Subsequently, the operation of the 3D model creation support process executed by the three-dimensional model creation device 100 will be described. For example, the user instructs the input device 340 to start the 3D model creation support process, and when the control unit 400 receives the instruction, the 3D model creation support process shown in FIG. 4 is started.

When the 3D model creation support process is started, the control unit 400 displays the DR list screen shown in FIG. 5 on the display device 330 (step S10). The DR list screen includes a DR name input field, a list of verification items, and a "3D model display" button.

The user operates the input device 340 and clicks the downward triangular button at the right end of the DR name input field on the DR list screen. In response to the click operation, the control unit 400 displays a pull-down list of DR names of each verification procedure manual stored in the verification procedure manual DB 210. The user operates the input device 340 to select the DR name of the target design review from the list. The control unit 400 refers to the verification procedure manual DB 210 and displays the verification item name of each verification item included in the verification procedure manual specified by the selected DR name in the verification item list.

Subsequently, the user operates the input device 340, checks the verification item to be executed from the verification item list, and clicks the "3D model display" button. In response to the click operation, the control unit 400 identifies the objects (parts, jigs and tools, work center) required for the verification work in the selected verification item (step S20). Specifically, the control unit 400 may specify the part ID, the jig / tool ID, and the work center ID associated with the selected verification item name in the verification procedure manual with reference to the verification procedure manual DB 210. .. Further, the control unit 400 refers to the component DB 220, the jig tool DB 230, and the work center DB 240, and appropriately acquires the component, the jig tool, the name of the work center, the captured image, and the like corresponding to the specified ID.

Subsequently, the control unit 400 displays the 3D model list screen as shown in FIG. 6 on the display device 330 (step S30). The 3D model list screen includes a "3D model creation" button and a "preview" button. Further, on the 3D model list screen, the name of the object specified in step S20 and the captured image are displayed in the parts list area, the jig / tool list area, and the work center list area for each object type. In the parts list area, the jig / tool list area, and the work center list area, a table showing the presence / absence of a three-dimensional model of the displayed object, the presence / absence of a two-dimensional model, and the presence / absence of actual data is displayed. The presence or absence of these may be determined by the control unit 400 by searching the component DB 220, the jig tool DB 230, the work center DB 240, the 2D model DB 250, and the 3D model DB 260.

Here, in order to carry out the verification work of the design review, it is necessary to create in advance a three-dimensional model of all the objects required for the verification work displayed on the 3D model list screen. By referring to the table of the presence / absence of the model in the parts list area, the jig / tool list area, and the work center list area on the 3D model list screen shown in FIG. Therefore, the user operates the input device 340 and clicks the "3D model creation" button. In response to the click, the control unit 400 creates a 3D model of an object displayed on the 3D model list screen that has not yet created a 3D model (hereinafter, also referred to as a model uncreated object). The model creation process is executed (step S40). The details of the 3D model creation process will be described with reference to the flowchart of FIG.

First, the control unit 400 selects one unmodeled object (step S401). Then, the control unit 400 refers to the 2D model DB 250 and determines whether or not a two-dimensional model of the selected uncreated model object has been created (step S402).

When the two-dimensional model is created (step S402; Yes), the control unit 400 displays the 2D → 3D conversion screen shown in FIG. 8 on the display device 330 (step S403). On this 2D → 3D conversion screen, the 2D model of the uncreated object acquired from the 2D model DB 250 is displayed in the 2D preview area, and its attribute information (name, dimensions, etc.) is displayed on the right side thereof. In addition, the 2D → 3D conversion screen has an "unnecessary part designation" button, a "bottom designation" button, a "bottom height designation" button, a "side rising side designation" button, a "side depth designation" button, and a "3D conversion" button. , Includes "Reflect Model" button.

After confirming the 2D model and attribute information displayed in the 2D preview area, the user can use the input device 340 to specify the "unnecessary part" button, "bottom surface designation" button, and "bottom height designation" if necessary. ”Button,“ Specify side rising side ”button, and“ Specify side depth ”button to specify (change) parameters for 3D conversion.

Specifically, the user clicks the "Specify unnecessary part" button, the "Bottom surface designation" button, or the "Side rising side designation" button, and then clicks on a specific part of the 2D model in the 2D preview area. Specify the parameter corresponding to the button. In addition, the user can specify the height or depth by clicking the "bottom height specification" button or the "side depth specification" button and then dragging a specific part of the 2D model in the 2D preview area. .. In addition, the appearance of the two-dimensional model in the 2D preview area is appropriately changed along with the specification of these parameters.

After setting the parameters, the user clicks the "3D conversion" button. In response to the click operation, the control unit 400 deletes unnecessary parts, stretches the bottom surface, raises the side surface, and extrudes the side surface of the 2D model based on the specified parameters, for example, by the method of RPA (Robotic Process Automation). After performing the processing such as, the conversion processing from the 2D model to the 3D model is performed, and the converted 3D model is displayed in the 3D preview area as shown in FIG.

After confirming the displayed 3D model, the user clicks the "Reflect model" button. In response to the click operation, the control unit 400 registers the displayed 3D model in the 3D model DB 260 as a 3D model of the model-uncreated object (step S404). Then, the process proceeds to step S412. If the user is not satisfied with the displayed 3D model, the user may set the above-mentioned parameters again and recreate the 3D model.

Here, the processes of steps S403 and S404 described above are processes performed when the 2D model of the model-uncreated object is stored in the 2D model DB 250. On the other hand, when the 2D model of the model-uncreated object is not stored in the 2D model DB 250 (step S402; No), the control unit 400 selects the 3D model DB 260 from the 3D model DB 260 based on the actual data of the model-uncreated object. , Identify a similar object similar to the unmodeled object (step S405).

Specifically, the control unit 400 refers to the component DB 220, the jig tool DB 230, or the work center DB 240 to acquire a captured image of the actual model uncreated object. Then, the control unit 400 uses a known image recognition technique using AI to capture an actual captured image of the unmodeled object and the actual object of other objects stored in the component DB 220, the jig tool DB 230, and the work center DB 240. An object having a similarity equal to or higher than a predetermined threshold value and having a 3D model stored in the 3D model DB 260 may be specified as a similar object by obtaining the similarity with the captured image of. If the conditions are met, a plurality of similar objects are specified.

When a similar object is specified in step S405 (step S406; Yes), the control unit 400 displays a similar model list screen that displays a list of similar object names, captured images, similarity, and the like as shown in FIG. It is displayed on 330 (step S407).

Then, the user operates the input device 340, selects an object for which the 3D model is to be diverted from the similar objects displayed in the list, and then clicks the "Reflect model" button. In response to the click operation, the control unit 400 newly registers the 3D model of the selected similar object stored in the 3D model DB 260 in the 3D model DB 260 as a 3D model of the uncreated object (step S408). .. Then, the process proceeds to step S412.

On the other hand, when there is no similar object (step S406; No), the control unit 400 scans the unmodeled object in 3D based on the information such as the size and the storage location indicated by the actual data of the unmodeled object. It is determined which of the handy type 3D scanner 310 and the stationary type 3D scanner 320 is suitable (step S409). Then, the control unit 400 displays a 3D scan guide screen as shown in FIG. 11 on the display device 330 instructing the handy type 3D scanner 310 or the stationary type 3D scanner 320 to perform the three-dimensional scan of the unmodeled object. Display (step S410). In this 3D scan guide screen, information indicating the captured image, the name, and the storage location of the model-uncreated object to be scanned is acquired from the component DB 220, the jig tool DB 230, or the work center DB 240 and displayed.

The user follows the instructions on the 3D scan guide screen to scan the actual object of the unmodeled object in three dimensions with the specified handy 3D scanner 310 or stationary 3D scanner 320, and when the scan is completed, the "3D scan guide screen" " Click the "Finish" button. In response to the click operation, the control unit 400 registers the 3D model created by the handy type 3D scanner 310 or the stationary type 3D scanner 320 in the 3D model DB 260 as a 3D model of the model uncreated object (step S411). ). Then, the process proceeds to step S412.

In step S412, the control unit 400 refers to the 3D model DB 260 and determines the presence or absence of the model-uncreated object (step S412). If there is still an unmodeled object (step S412; Yes), the process returns to S401, and a series of processes for creating a three-dimensional model of the unmodeled object is repeated. When there is no model-uncreated object (step S412; No), the 3D model creation process ends.

Returning to FIG. 4, when the 3D model creation process is completed, the control unit 400 causes the display device 330 to display the 3D model list screen shown in FIG. 12 again (step S50). By executing the 3D model creation process, the 3D models of all the objects displayed on the 3D model list screen are created, and all are updated to 3D "Yes" in the table showing the presence or absence of the model.

Then, the user operates the input device 340 to check the object to be verified in the design review, and then clicks the "preview" button. In response to the click operation, the control unit 400 displays the checked object on the preview screen shown in FIG. 13 (step S60). The preview screen includes a "DMU tool output" button. The user can operate the input device 340 to rotate, enlarge, or reduce the object displayed on the preview screen.

Further, when the user operates the input device 340 and clicks "DMU tool output" on the preview screen, the control unit 400 transfers the three-dimensional model of the object checked as the verification target to a specific folder. Then, the control unit 400 activates the DMU (Digital Mock-Up) tool, reads the three-dimensional model placed in the specific folder, and displays the display screen of the DMU tool (not shown) on the display device 330 (step S70). ). The following will be appropriately reviewed by the DMU tool. This completes the 3D model creation process.

As described above, according to the present embodiment, the objects necessary for the design review of the product are determined based on the data of the verification procedure manual, and among the determined objects, the model-uncreated object for which the three-dimensional model is not created is not created. The three-dimensional model creation process is executed for the target. Therefore, only the three-dimensional model of the object required for the design review can be efficiently created.

Further, according to the present embodiment, if there is a 2D model of an object for which a model has not been created, a 3D model is created from the 2D model. If there is no 2D model, a similar object is specified from the actual data and the 3D model of the similar object is diverted. Furthermore, if there is no similar object, a 3D scanner suitable for 3D scanning the actual object of the unmodeled object is determined, and the actual 3D object of the unmodeled object is scanned 3D with the determined 3D scanner. Instruct the user. In this way, since the three-dimensional model is created according to the clear guideline, it is possible to efficiently create the three-dimensional model in a short time.

(Modification example)
The above-described embodiment is an example of the present invention, and various modifications and applications are possible.

For example, the three-dimensional model creating device 100 may include a 3D scanner other than the handy type 3D scanner 310 and the stationary type 3D scanner 320. Further, the three-dimensional model creating device 100 may be connected so as to be able to communicate with an external 3D scanner.

In the above embodiment, an example of creating a three-dimensional model of an object necessary for carrying out a design review on an elevator installation method has been shown, but the present invention is not limited to this, and various types of product designs are provided. The present invention is applicable to the creation of the three-dimensional model required for the review.

In the above embodiment, a three-dimensional model of parts, jigs and tools, and a work center is shown as a three-dimensional model of an object necessary for carrying out a design review, but the present invention is not limited to this, and the present invention is not limited to this. The present invention is applicable in the context of creating a three-dimensional model of all kinds of objects required.

In the 3D model creation process, the 3D model of the similar object selected by the user from the similar objects displayed on the similar model list screen shown in FIG. 10 is registered as the 3D model of the model-uncreated object. However, the 3D model of the object having the highest degree of similarity may be automatically registered as the 3D model of the unmodeled object without displaying the similar model list screen. By doing so, the processing time of the three-dimensional model creation process can be shortened.

Further, for example, when there is no 2D model of the unmodeled object, there is no actual data, there is no inventory of the actual product itself, and 3D scanning of the actual product is not possible, the control unit 400 performs the 3D model creation process as shown in FIG. You may do it.

In this case, first, the control unit 400 causes the display device 330 to display the condition input screen shown in FIG. 15 (step S1).

The user operates the input device 340, inputs each condition such as a name, a model name, and a size from the condition input screen, and the priority of each condition, and clicks the "search" button. In response to the click, the control unit 400 detects a reference object that matches the conditions from the part DB 220, the jig tool DB 230, and the work center DB 240 (step S2). At this time, the control unit 400 does not detect only those that completely match the conditions, but performs a so-called fuzzy search, and selects those that partially match the conditions, those that match some of the input conditions, and the like. Widely detect. In addition, various methods can be considered as the detection method here. For example, the control unit 400 may set that the condition having the first priority is at least partially matched as the minimum condition for detection.

Subsequently, the control unit 400 obtains the similarity between the unmodeled object and each detected reference object (step S3). Specifically, the control unit 400 may calculate the similarity based on the number of matches with each condition input by the detected reference object, the degree of coincidence, the priority of each condition, and the like. For example, the control unit 400 may calculate the similarity so that the larger the number of reference objects that match each input condition, the higher the value. Further, the control unit 400 resembles the reference object whose priority is exactly the same as that of the upper condition so as to have a higher value than the partially matching reference object or the reference object whose priority is exactly the same as the lower priority condition. The degree may be calculated.

Subsequently, the control unit 400 displays on the display device 330 the reference model list screen shown in FIG. 16, which displays a list of each reference object detected in step S2 together with the similarity obtained in step S3 (step S4). The user operates the input device 340, selects one of the reference objects displayed in the list that he / she wants to use the 3D model, and then clicks the "Reflect model" button. In response to the click operation, the control unit 400 newly registers the 3D model of the selected reference object stored in the 3D model DB 260 in the 3D model DB 260 as a 3D model of the uncreated object (step S5). .. This completes the 3D model creation process.

In this way, in this three-dimensional model creation process, reference objects are displayed in a list based on the conditions input by the user, and the one selected from them is diverted as a 3D model of the unmodeled object. Therefore, even if there is no 2D model and actual data, it is possible to efficiently create a three-dimensional model of an object necessary for design review.

Further, by applying the program executed by the control unit 400 of the three-dimensional model creating device 100 to an existing computer, it is possible to make the computer function as the three-dimensional model creating device 100 according to the present invention.

The distribution method of such a program is arbitrary, and is a computer-readable recording medium such as a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk), an MO (Magneto Optical Disk), or a memory card. It may be stored in and distributed via a communication network such as the Internet or an intranet.
