DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate explanations will be omitted. Furthermore, the dimensional proportions in the drawings are exaggerated for the convenience of explanation, and may differ from the actual proportions.

[0014] <Configuration of Decorative Sheet Manufacturing System 100> 1 is a block diagram illustrating the schematic configuration of a decorative sheet manufacturing system 100 according to one embodiment. The decorative sheet manufacturing system 100 includes an information processing device 10, a network 20, a cloud server 30, a printing device 40, and a cutting plotter 50.

[0015] The information processing device 10 is a computer such as a smartphone, a tablet terminal, or a personal computer, and includes a control unit 11, an imaging unit 12, a touch panel 13, and a communication unit 14. In the following, the present embodiment will be described taking as an example a case where the information processing device 10 is a smartphone.

[0016] The control unit 11 comprehensively controls the imaging unit 12, the touch panel 13, and the communication unit 14 to realize various functions. The control unit 11 has a CPU (Central Processing Unit) 111, a RAM (Random Access Memory) 112, a ROM (Read Only Memory) 113, and an auxiliary storage unit 114.

[0017] The CPU 111 executes programs such as an OS (Operating System) and an information processing program loaded in the RAM 112, and controls the operation of the information processing device 10. The information processing program is stored in advance in the ROM 113 or the auxiliary storage unit 114. The RAM 112 also stores data and the like temporarily generated by the processing of the CPU 111. The ROM 113 stores programs executed by the CPU 111, as well as data, parameters, and the like used in executing the programs. The auxiliary storage unit 114 includes, for example, a flash memory.

[0018] The imaging unit 12 has at least one camera and, in accordance with instructions from the control unit 11, photographs the object to which the decorative sheet is to be attached from different viewpoints. The camera may be, for example, a visible light camera or an infrared camera. The camera may also be a stereo camera. Data of the photographed image (visible image or infrared image) is sent to the control unit 11 and is used to generate a three-dimensional model, as described below.

[0019] Alternatively, the imaging unit 12 may have a LiDAR sensor instead of a camera, measure the distance between the LiDAR sensor and the object, and transmit information about the measured distance (distance image) to the control unit 11. In this case, the three-dimensional model is generated based on the distance image. The following description will be given taking as an example a case where the imaging unit 12 has a stereo camera.

[0020] The touch panel 13 has a position input device such as a touchpad and a display device (display unit) such as a liquid crystal display or an organic light-emitting display, and can simultaneously process the reception of user input and the display of information. For example, the touch panel 13 displays an operation menu on the display device and receives user input (operations) on the operation menu. In this embodiment, the display device also displays a three-dimensional model, a development diagram of the three-dimensional model laid out on a plane, etc., as will be described later.

[0021] The communication unit 14 communicates with the cloud server 30 via a network 20, which may include a wireless communication network and the Internet. The communication unit 14 includes a receiving unit that receives data transmitted from the cloud server 30 and a transmitting unit that transmits data to the cloud server 30.

[0022] The printing device 40 prints an image based on image data onto an adhesive sheet (media). The printing device 40 may employ any of the following printing methods: electrophotography, inkjet, or thermal transfer. The cutting plotter 50 cuts (punches) the adhesive sheet onto which the image has been printed by the printing device 40 into a predetermined shape. The printing device 40 and the cutting plotter 50 constitute a processing device 60. The processing device 60 may further include a device for applying a laminate film to the printed adhesive sheet. The processing device 60 may also further include a device for applying application tape to the cut adhesive sheet. The application tape is applied to the non-adhesive side of the adhesive sheet to facilitate application of the adhesive sheet, and is peeled off after the adhesive sheet has been applied to an article.

[0023] <Functions of control unit 11> As shown in Figure 2, in this embodiment, the CPU 111 executes the information processing program, and the control unit 11 functions as an image acquisition unit 201, a model generation unit 202, an expansion unit 203, a pattern information reception unit 204, an image generation unit 205, a media selection information reception unit 206, a curvature calculation unit 207, and a media selection unit 208.

[0024] The image acquisition unit 201 acquires an image (visible image, infrared image, or distance image) of the item to which the decorative sheet is to be attached.

[0025] The model generation unit 202 generates a 3D model of the article based on an image of the article. For example, when the image acquired by the image acquisition unit 201 is a visible image or an infrared image, the model generation unit 202 generates a 3D model of the article based on multiple images of the article taken from different viewpoints. The 3D model can be generated using a known technique (e.g., volume intersection method, etc.). The volume intersection method is a technique for generating a 3D model of the article by extracting silhouette images of the article from multiple images of the article taken from different viewpoints, projecting each silhouette image into three-dimensional space, and determining the intersection of each volume. The 3D model can be, for example, a polygon model that approximately represents a curved surface with a set of polygons. The polygon model can be generated using a known technique (e.g., marching cubes method, etc.). Note that the 3D model may include not only a polygon model consisting of multiple flat surfaces, such as a polygonal model, but also a curved surface.

[0026] The unfolding unit 203 unfolds the surface of the 3D model of the article into a plane. For example, when a polygon model is generated as the 3D model of the article, the unfolding unit 203 generates a development of the 3D model based on the polygon model of the article. Note that the following description will be given taking as an example a case where the 3D model is unfolded into a development, but it is not limited to a development, and the unfolding may also be a plane that includes a convex or concave shape in part.

[0027] The design information receiving unit 204 receives information regarding the design to be placed on the surface of the three-dimensional model and the position where the design is to be placed. As will be described later, the user can input the design (pattern or image) and the position of the design on the development drawing via the touch panel 13, thereby inputting the design placement on the surface of the three-dimensional model. Also, instead of inputting the position on the surface of the development drawing where the design is to be placed, the user can also directly input the position on the surface of the three-dimensional model.

[0028] The image generation unit 205 places a design on the surface of the three-dimensional model and generates image data for printing the placed design on an adhesive sheet. The design can be placed on the entire surface of the three-dimensional model or on part of it, according to a user's designation.

[0029] The media selection information receiving unit 206 receives media selection information used to select media. The media selection information includes at least one of adherend information, which includes information about the article as the adherend, the usage conditions for using the decorative sheet, and the material of the decorative sheet. The adherend information includes at least one of the material of the adherend and the maximum curvature. Usage conditions include, for example, the location of use (usage temperature) and application period. Note that, since the usage temperature often depends on the location of use, the media selection information receiving unit 206 can be configured to include at least one of the location of use and the usage temperature. As will be described later, the media selection information receiving unit 206 receives media selection information input by the user via the touch panel 13.

[0030] The adherend material may be, for example, PP, PE, PS, PET, PVC, PC, ABS, acrylic paint, melamine paint, stainless steel, paper, cardboard, concrete, tile, wood board, ceramics, glass, Teflon (registered trademark), fabric, wallpaper, etc., but is not limited to these materials.

[0031] The maximum curvature of the adherend is the maximum value of the curvature of the adherend to which the decorative sheet is attached. Normally, the greater the curvature of the adherend, the more likely it is that an adhesive sheet attached to the adherend will peel off, so it is preferable to attach an adhesive sheet with high adhesiveness to an adherend with a large curvature. The media selection information receiving unit 206 receives the maximum curvature as input by the user via the touch panel 13. The maximum curvature can also be calculated by the curvature calculation unit 207 based on a three-dimensional model, and when the maximum curvature is calculated by the curvature calculation unit 207, the media selection information receiving unit 206 receives the calculated maximum curvature.

[0032] The places of use may be, for example, indoors (e.g., 20°C to 30°C), indoors in winter (e.g., 0°C to 20°C), indoors in summer (e.g., 30°C to 45°C), outdoors in winter (simulating a ski resort, e.g., -20°C to 0°C), outdoors in summer (simulating the seaside, e.g., 30°C to 40°C), inside a car in summer (e.g., 30°C to 60°C), or inside a refrigerator (e.g., -10°C to 15°C), but are not limited to these places (temperatures).

[0033] The application period can be any period from several days to about 10 years. The application period can typically be 3 days, 1 week, 1 month, 3 months, 6 months, 1 year, 3 years, 5 years, or 10 years. The application period is, for example, a period during which the PSA sheet is expected to exhibit sufficient adhesive strength to the adherend, and can be set on the assumption that the PSA sheet can be easily peeled off from the adherend after the application period has expired.

[0034] The media selection information receiving unit 206 also receives the adhesive sheet material used for the decorative sheet from a list of materials used for adhesive sheets. Materials used for adhesive sheets include, for example, polyvinyl chloride.

[0035] The media selection unit 208 selects an adhesive sheet to be used for the decorative sheet based on the media selection information. The adhesive sheet to be used for the decorative sheet can be selected by the user from a list of pre-registered adhesive sheets, or the media selection unit 208 can automatically select it. In this case, for example, information regarding the usable adherend material, usable temperature range, and range of period during which it can be attached to the adherend is pre-registered in the auxiliary storage unit 114 for each model number of the adhesive sheet. The media selection unit 208 selects an adhesive sheet to be used for the decorative sheet based on the information regarding the usable adherend material, usable temperature range, and range of period during which it can be attached to the adherend registered in the auxiliary storage unit 114 and the media selection information input by the user. More specifically, the media selection unit 208 determines whether the adherend material, usable temperature, and attachment period of the input media selection information are each included in the usable adherend material, usable temperature range, and range of period during which it can be attached to the adherend registered in the auxiliary storage unit 114. The media selection unit 208 outputs the model number of the adhesive sheet that is determined to fall within the range of usable adherend material, usable temperature range, and usable period of time that can be attached to the adherend, registered in the auxiliary memory unit 114, as the selection result.

[0036] The use conditions may also include the difficulty of applying the adhesive sheet. For example, if there is no difference in the judgment results between adhesive sheets for the adherend material, use temperature, and application period in the media selection information, the media selection unit 208 can select an adhesive sheet taking into consideration the difficulty of applying the adhesive sheet. For example, if there is no difference in the judgment results between adhesive sheets for each of the above items, the media selection unit 208 can select adhesive sheets in order of relative ease of application.

[0037] (Decorative sheet manufacturing method) In the decorative sheet manufacturing method of this embodiment, image data to be printed on a decorative sheet to be attached to an article is generated in the information processing device 10, and the image data is printed on an adhesive sheet in the processing device 60, which is then cut into a predetermined shape suitable for attachment. Below, the decorative sheet manufacturing method will be described in detail, dividing it into processing on the information processing device 10 side and processing on the processing device 60 side.

[0038] <Processing on the Information Processing Device 10 Side> Fig. 3 is a flowchart illustrating the processing steps on the information processing device 10 side in the decorative sheet manufacturing method. The processing of the flowchart shown in Fig. 3 is realized by CPU 111 executing an information processing program. Fig. 4 is a schematic diagram showing an example of an article to which a decorative sheet is to be attached, Fig. 5 is a schematic diagram illustrating a three-dimensional model of the article shown in Fig. 4, and Fig. 6 is a schematic diagram illustrating a development of the three-dimensional model shown in Fig. 5. Fig. 7 is a schematic diagram illustrating the acceptance and arrangement of a design for the development shown in Fig. 6, Fig. 8 is a schematic diagram illustrating a screen for accepting media selection information, and Fig. 9 is a schematic diagram illustrating a screen for selecting an adhesive sheet.

[0039] As shown in Fig. 3, first, an image of an article is acquired (step S101). As shown in Fig. 4, the user operates the information processing device 10 to photograph an article 300 to which a decorative sheet is to be attached. If the imaging unit 12 has a stereo camera equipped with first and second visible light cameras, the first and second visible light cameras capture visible images taken from different viewpoints and transmit them to the control unit 11. The control unit 11 stores the captured visible images in RAM 112. The user photographs the article 300, for example, at different positions A, B, C, ...

[0040] For example, positions A, B, and C may be positions facing the front, side, and top surface of the article 300, respectively. By photographing the article 300 at a plurality of different positions, a plurality of images of the article photographed from different viewpoints are obtained. In the example shown in FIG. 4, the article 300 is, for example, a cylindrical object whose top and bottom surfaces are perfect circles with diameters of 9 cm and 8 cm, respectively, and whose height is 10 cm. The image acquisition unit 201 acquires images of the front, side, and top surface of the article 300 photographed by each of the first and second visible light cameras.

[0041] Next, a 3D model is generated (step S102). As shown in FIG. 5, the control unit 11 controls the display device of the touch panel 13 to display an operation menu 401 on a screen 400. The operation menu 401 includes, for example, a "Generate 3D model" button 402, a "Generate development view" button 404, and a "Receive and arrange design" button 405. When the user selects the "Generate 3D model" button 402 with a hand or finger 403, the model generation unit 202 generates a 3D model 406 of the article 300 based on multiple images of the article 300, and displays the model 406 on the screen 400.

[0042] Next, the surface of the three-dimensional model 406 is developed into a plane (step S103). As shown in Fig. 6, when the user selects a "Generate development" button 404 with a hand or finger 403, the development unit 203 generates a development 407 of the three-dimensional model 406 and displays it on the screen 400. For example, the development 407 consists of an upper surface 408, a lower surface 409, and a side surface 410.

[0043] Next, the design is accepted (step S104). In Fig. 6, when the user selects "Accept and arrange design" button 405 with a finger or the like 403, control unit 11 controls the display device of touch panel 13 to display operation menu 411 on screen 400, as shown in Fig. 7. Operation menu 411 may include, for example, a "Select pattern" list 412, a "Select image" button 413, a "Complete design acceptance" button 414, and a "Generate image data" button 415.

[0044] The user selects a pattern to be placed on the development drawing 407 and a position on the development drawing 407 where the pattern is to be placed. The user can select a desired pattern from a plurality of patterns (e.g., cross, diagonal line, dashed line, cross, etc.) in a "Pattern selection" list 412. The user can also input the position of the pattern by selecting, for example, one of the top surface 408, bottom surface 409, and side surface 410. FIG. 7 illustrates an example in which the user selects the top surface 408 with a hand or finger or the like 403.

[0045] Furthermore, when the user operates the "Select Image" button 413, the user can select a desired image, illustration, etc. as a design from a list of pre-registered images. After the user inputs the design and the position where the design is to be placed, the user can operate the "Design Acceptance Complete" button 414 to complete the input of the design and the design placement.

[0046] The design to be selected may be a pattern, image, illustration, etc. that is pre-stored in the cloud server 30, etc., or a pattern, illustration, etc. that the user has drawn using the touch panel 13, etc., or an image that the user has taken, may be used as the design.

[0047] Furthermore, when the user draws a design, the control unit 11 can be configured to display a drawing button for activating other drawing software in the operation menu 411, and when the user operates the drawing button, the information processing program of this embodiment can be configured to cooperate with the other drawing software. The user creates a pattern or illustration using the other drawing software, and the data of the created pattern or illustration is saved in the RAM 112 or uploaded to the cloud server 30 or the like and used as a design.

[0048] Next, image data is generated (step S105). When the user selects the "Generate Image Data" button 415 with a hand or finger 403, the image generation unit 205 places a pattern on the surface of the three-dimensional model and generates image data for printing the placed pattern on a decorative sheet. The example in FIG. 7 shows a case where a cross pattern is placed on the top surface 408. The pattern information receiving unit 204 receives information about the cross pattern to be placed on the development drawing 407 and the position on the development drawing 407 where the cross pattern is to be placed. The information about the position includes, for example, the area of ​​the top surface 408 or coordinates (vertex coordinates, center coordinates, center of gravity coordinates, etc.). In addition, a diagonal line pattern is placed on the side surface 410.

[0049] Next, media selection information is received (step S106). The media selection information receiving unit 206 receives media selection information including at least one of the conditions for using the decorative sheet, adherend information for the article 300 as the adherend, and the material of the decorative sheet. The conditions for using the adhesive sheet include environmental conditions such as the location and temperature of use, and the duration of application.

[0050] 8, the control unit 11 displays an operation menu list 418 on the screen 400. The operation menu list 418 may include, for example, an "Accept media selection information" button 416 and a "Select adhesive sheet" button 417. When the user performs an operation of selecting the "Accept media selection information" button 416 with a finger or the like 403, the media selection information receiving unit 206 displays an "Adherend material" list 419, an input field for maximum curvature 420, a "Calculate maximum curvature" button 421, a "Location of use" list 422, an input field for use temperature 423, and an input field for use period 424.

[0051] The media selection information receiving unit 206 receives at least one of the adherend material and the maximum curvature of the article 300 as adherend information. The figure illustrates an example in which the user selects "PP" from an "adherend material" list 419, which includes "PP," "PE," and "PS," and enters "0.25" in the maximum curvature input field 420. After a 3D model of the article 300 is generated in step S102, the curvature calculation unit 207 calculates the maximum curvature of the article 300 based on the 3D model automatically, or when the user operates a "Calculate Maximum Curvature" button 421. The media selection information receiving unit 206 receives the maximum curvature calculated by the curvature calculation unit 207 or the maximum curvature entered by the user in the input field 420.

[0052] The figure also illustrates an example in which the user selects "indoors" from a "usage location" list 422 that includes "indoors," "outdoors," "in the car," and "refrigerator." The user also inputs values ​​into an input field 423 for the usage temperature and an input field 424 for the usage period, and the media selection information receiving unit 206 receives the usage temperature and usage period. The figure illustrates an example in which the user inputs 20°C to 30°C as the usage temperature and 3 days as the usage period.

[0053] Next, an adhesive sheet is selected (step S107). As shown in FIG. 9, the control unit 11 displays an operation menu 425 on the screen 400. The operation menu 425 may include, for example, an "Accept media selection information" button 416, an "Select adhesive sheet" button 417, and an "Process media" button 426. When the user selects the "Select adhesive sheet" button 417 with a finger or the like 403, the media selection unit 208 selects an adhesive sheet to be used for the decorative sheet based on the media selection information. Alternatively, the media selection unit 208 can display an "Adhesive sheet" list 427 on the screen 400 and allow the user to select an adhesive sheet via the touch panel 13.

[0054] The media selection unit 208 can also display an "adhesive sheet color" list 428 on the screen 400, and allow the user to select the color of the adhesive sheet that will be the background for the design to be printed via the touch panel 13. The color of the adhesive sheet can be selected from, for example, transparent or colored (white, blue, etc.). Note that a preview of a development 407 on the selected adhesive sheet may be displayed on the screen 400, allowing the user to check the image of the design to be printed on the selected adhesive sheet.

[0055] The control unit 11 can also receive a user instruction regarding whether or not to apply a laminate film to the printed adhesive sheet. Furthermore, the control unit 11 can recommend to the user that a laminate film be applied depending on the usage conditions, etc., of the media selection information received in step S108. For example, the control unit 11 recommends to the user that a laminate film be applied to the adhesive sheet when the usage conditions of the media selection information are "outdoors" or the usage period is one month or longer.

[0056] Next, the printing data and the cutting data are transmitted (step S108). When the user selects the "process media" button 426 with his / her finger or the like 403, the control unit 11 arranges for media to be supplied to the processing device 60, and transmits the printing data and the cutting data to the cloud server 30 via the network 20.

[0057] The printing data includes image data of the article 300, printing conditions, and information about the adhesive sheet. The printing conditions include, for example, adhesive sheet size settings, enlargement / reduction settings, color / monochrome settings, etc. The user can change the settings of the printing conditions through the touch panel 13. The information about the adhesive sheet is the result of selection by the media selection unit 208 or the user, such as the model number or name of the adhesive sheet.

[0058] The cutting data is generated based on a three-dimensional model 406 of the article 300 or a development 407 of the three-dimensional model 406, and includes information (for example, coordinates) about the position where the adhesive sheet is to be cut out.

[0059] 3, an image of an item is acquired, a 3D model 406 of the item and a development 407 of the 3D model 406 are generated based on the image of the item, and a pattern is placed on at least a portion of the surface (top and side surfaces) of the development 407. Image data is then generated for printing the placed pattern on a decorative sheet.

[0060] While the above example mainly describes placing a design on the development 407 of the 3D model 406 of the object 300, it is also possible to place a design directly on the 3D model 406 without generating the development 407. In this case, after generating the 3D model 406 in FIG. 5, the "Accept and Place Design" button 405 is operated instead of the "Generate Development" button 404. This operation allows the design to be placed directly on the corresponding surface of the 3D model, for example, when the design is to be placed only on a specific surface of the object. For example, in the case of a plate-shaped object such as a floor tile, a decorative sheet is typically attached to the portion with a large surface area that becomes the floor, and the decorative sheet is omitted for the other surfaces with a smaller surface area. By directly placing a design on the surface of the 3D model of the floor tile that corresponds to the floor, the process of generating a development can be omitted.

[0061] <Processing on the processing device 60 side> Fig. 10 is a flowchart illustrating the processing procedure on the processing device 60 side of the decorative sheet manufacturing system 100 shown in Fig. 1, and Fig. 11 is a schematic diagram illustrating an overview of the processing device 60. The processing of the flowchart shown in Fig. 10 is achieved by cooperation between the printing device 40 and the cutting plotter 50. Fig. 12 is a schematic diagram illustrating a finished product in which a decorative sheet manufactured by the decorative sheet manufacturing system 100 shown in Fig. 1 is attached to the article 300 shown in Fig. 4.

[0062] As shown in Fig. 10, an image of the image data is printed on an adhesive sheet (step S201). As shown in Fig. 11, the printing device 40 acquires image data of the item 300, information about the adhesive sheet, and printing conditions from the cloud server 30. The printing device 40 prints the image of the image data on an adhesive sheet corresponding to the information about the adhesive sheet based on the printing conditions.

[0063] Furthermore, when a user's instruction to apply a laminate film is received, the method may further include a step of applying a laminate film to the printed adhesive sheet.

[0064] Next, the adhesive sheet is cut into a predetermined shape (step S202). The cutting plotter 50 acquires cutting data from the cloud server 30 and cuts the adhesive sheet with the printed image into a predetermined shape based on the cutting data. It is also possible to add a step of applying application tape to the adhesive sheet (decorative sheet) after cutting. The adhesive strength of the application tape to the decorative sheet is weaker than the adhesive strength of the decorative sheet to the article 300.

[0065] The cut adhesive sheet is provided to the user as a decorative sheet, and the user attaches the decorative sheet to predetermined positions (e.g., the top and sides) of the article 300 to obtain a finished product, as shown in Figure 12.

[0066] (Examples of application to other items) Fig. 13 is a schematic diagram showing another example of an article to which a decorative sheet can be attached, and Fig. 14 is a schematic diagram illustrating a three-dimensional model of the article shown in Fig. 13. Also, Fig. 15 is a schematic diagram illustrating a development view of the three-dimensional model shown in Fig. 14, and Fig. 16 is a schematic diagram illustrating a preview image of the finished product in which a decorative sheet is attached to the article shown in Fig. 13.

[0067] 13, an example will be shown in which a decorative sheet is attached to a model train (toy) as the article 302. The user operates the information processing device 10 to capture images of the front (rear), side, and top of the article 302. The image acquisition unit 201 acquires a plurality of images (images of the front, side, and top) captured by the imaging unit 12 and stores them in the RAM 112.

[0068] As shown in FIG. 14, the model generation unit 202 generates a three-dimensional model 431 of the article 302 based on a plurality of images of the article 302 (the operation menu and the like are omitted from the drawing; the same applies to FIG. 15).

[0069] 15, the development unit 203 generates a development 500 of the three-dimensional model 431. The development 500 has a front surface 501, a back surface 502, a right surface 503, a left surface 504, and a top surface 505.

[0070] For example, the user specifies that the "balloon" design should be placed on the front surface 501, and that the two "flower" and "fish" designs should be placed on the right side surface 503 and left side surface 504. Design information receiving unit 204 receives the "balloon," "flower," and "fish" designs and their position coordinates. Image generating unit 205 places the "balloon," "flower," and "fish" designs at the positions specified by the user, and generates image data for printing the placed designs on an adhesive sheet.

[0071] 16 , the image generation unit 205 can also display a preview image 432 of a finished product in which a decorative sheet is attached to the item 302 on the screen 400. The control unit 11 displays an operation menu 429 on the screen 400. The operation menu 429 may include, for example, an “Accept Media Selection Information” button 416, a “Select Adhesive Sheet” button 417, a “Process Media” button 426, and a “Preview Finished Product” button 430. When the user selects the “Preview Finished Product” button 430 with a hand or finger 403, the image generation unit 205 generates a preview image 432 of the finished product in which designs of “balloons,” “flowers,” and “fish” are inserted into a three-dimensional model 431, and displays the preview image 432 on the screen 400. By displaying the preview image 432 of the finished product on the screen 400, the user can get an idea of ​​the finished product before arranging for media.

[0072] In addition, the screen 400 may be configured to display a button for changing the color of the adhesive sheet selected from the "Adhesive Sheet Color" list 428 (Figure 9), so that the user can change the color of the adhesive sheet after checking the preview image 432.

[0073] The reception of media selection information, the selection of adhesive sheets, and the processing of media are as described above, and therefore detailed explanations thereof will be omitted.

[0074] The information processing device, information processing program, decorative sheet manufacturing system and method of the present embodiment described above have the following advantages.

[0075] The system is configured to generate a three-dimensional model (406, 431) of the object (300, 302) to which the decorative sheet is to be attached, arrange a pattern on at least a portion of the surface of the three-dimensional model (406, 431), and generate image data for printing the arranged pattern on an adhesive sheet. Therefore, an object cover that covers the surface of any object (300, 302) can be easily customized.

[0076] As described above, the information processing device, information processing program, and decorative sheet manufacturing system and method have been described in the embodiments. However, it goes without saying that those skilled in the art can make additions, modifications, and omissions to the present invention as appropriate within the scope of its technical concept.
