By the way, in the heat-expandable sheet, the thermal expansion of the image formation on the front surface side (one surface side) is often more conspicuous than the image formation on the back surface side (other surface side). Therefore, depending on the shape of the image (for example, the thickness and area of the line), it is appropriately selected whether to form an image on one side or the other side of the heat-expandable sheet to form an optimum image. It is preferable to do.

In this regard, the technique described in Patent Document 1 is intended to form an image of a heat absorbing portion of black or ash only on one surface side of a heat-expandable sheet and to form an image of a heat absorbing portion on the other surface side. Not. Therefore, in this technique, even when forming a three-dimensional image of a graph, a graph-shaped heat absorbing portion is formed only on one surface side of the heat-expandable sheet.
In other words, the technique described in Patent Document 1 does not select whether to form an image on one side or the other side of the heat-expandable sheet, so that more appropriate three-dimensional image formation (manufacturing of a three-dimensional model). Has the potential to be.

An object of the present invention is to produce a more appropriate three-dimensional model.

(First Embodiment)
FIG. 1 is a block diagram of a stereoscopic image forming system according to a first embodiment of the present invention.
The three-dimensional object manufacturing system 1000 includes a display device 100, a display operation unit 150, a two-dimensional image forming device 320, and a foaming device 310, and the two-dimensional image forming device 320 and the foaming device 310 are used to form a three-dimensional image forming device. It constitutes 300. The stereoscopic image forming apparatus 300 forms a stereoscopic image such as a bar graph or a pie chart on a heat-expandable sheet. Further, the display device 100 causes the display operation unit 150 to display an image such as a bar graph or a pie chart for forming an image. A bar graph or a pie chart is composed of a plurality of bars and a plurality of fan shapes, and is a graph for comparing the areas and ratios of the areas of each bar and the fan shape.

The display device 100 is a general-purpose information processing device connected to the display operation unit 150 by using an OS (Operating System), and is used as a control device for controlling the foaming device 310 and the two-dimensional image forming device 320. The display device 100 includes a control unit 10, a volatile storage unit 80, a non-volatile storage unit 90, and a communication unit 70. The volatile storage unit 80 is a RAM (Random Access Memory) and is used as a work memory. The non-volatile storage unit 90 is an HDD (Hard Disk Drive) or ROM (Read Only Memory), and stores an OS 91, an application program 93, a printer driver 92, graph data 94, and the like. The communication unit 70 is a LAN (Local Area Network) or USB (Universal Serial Bus) serial interface or parallel interface. In the present embodiment, the two-dimensional image forming apparatus 320 is connected by USB, and the foaming apparatus 310 is serially or parallel connected. The display operation unit 150 is a touch panel connected to the display device 100, and includes a display means for displaying a two-dimensional image and an input means for input by the operator.

The foaming device 310 is a halogen lamp as a heating device (heating device) for heating one or both sides of a heat-expandable sheet in which a foam layer (expansion layer) that foams (expands) by heat is laminated on one side of a mount. (Not shown).

The two-dimensional image forming apparatus 320 performs black printing (drawing) in which a specific portion of the heat-expandable sheet is foamed (expanded), or color prints the entire surface of the heat-expandable sheet with CMY (cyan, magenta, yellow). It is an inkjet printer. The two-dimensional image forming apparatus 320 includes image data (front surface data) of a specific portion that expands the front surface of the heat-expandable sheet, image data (back surface data) that expands the expansion layer from the back surface of the heat-expandable sheet, and a color image. Data is needed.

Since the halogen lamp strongly generates near-infrared light, it strongly heats black (carbon), and the amount of heating is small at the color printing portion of CMY. Therefore, the heat-expandable sheet having the foam layer foams (expands) only in the specific portion printed in black, and a three-dimensional model is formed. In other words, the two-dimensional image forming apparatus 320 prints a heat conversion layer (black layer) that converts near-infrared light into heat. Here, the ink for black printing contains carbon and contributes to foaming by irradiation with near-infrared light. The CMY ink does not contain carbon. Therefore, the black color mixed with CMY has a small calorific value and does not contribute to foaming. The three-dimensional model manufacturing system 1000 operates as a structure manufacturing system for manufacturing a structure of a three-dimensional image.

The generated graph data 94 includes front surface data in which an image is formed in black on the front surface of the heat-expandable sheet, back surface data in which an image is formed in black on the back surface of the heat-expandable sheet, and color on the surface of the heat-expandable sheet. It is composed of color image data that forms an image. The setting means 20 includes a boundary area / allocation means 21, an inner area / allocation means 22, and an axis / scale / allocation means 23. The boundary area / allocation means 21 allocates an area of a bar of a bar graph, a boundary between a fan shape of a pie chart and a background, and an area of a boundary with an adjacent area. The inner area / allocation means 22 allocates an area inside a bar in a bar graph or an area inside a pie chart. The axis / scale / allocation means 23 allocates graph axes and scales to surface data. Although the color image data is assigned as a surface color image, it does not contribute to thermal expansion.

The image forming control means 50 is a control means for controlling both the two-dimensional image forming apparatus 320 and the foaming apparatus 310 based on the graph data 94.

The communication control unit 60 is a control means for controlling the communication unit 70. The two-dimensional image forming device 320 is controlled by USB (Universal Serial Bus), and the foaming device 310 is controlled by a parallel I / F or a serial I / F. A digital video signal is transmitted to the display operation unit 150.

The bar graph 420 includes an area expression unit 410 represented by the area of a bar, a horizontal scale line 421, a vertical scale line 422, an item 423, a scale 424, and a background 415. The area expression unit 410 includes an inner region 411, which is an inner region (open region) of the bar, and a second boundary region 413, which is a boundary with the background 415. The open region is a concept that does not include a boundary, and the concept that includes a boundary is called a closed region. The inner region 411 is a portion obtained by removing the second boundary region, which is the outer peripheral portion of the bar of the bar graph 420, from the area expression unit 410, and has an area. The bar graph 420 is a graph having 1 series and 3 data, and one data is described in each item 423, and the number of items is three. Here, a series means a group of data of the same lineage.

The horizontal scale line 421 is a plurality of horizontal lines drawn at equal intervals and in parallel, and is a reference line for comparing the heights of the bars. The vertical scale lines 422 are a plurality of vertical lines drawn at equal intervals and in parallel, and are for distinguishing from adjacent bars, and may be omitted. Item 423 is a character string describing the contents of each bar. The scale 424 is a character string that quantitatively expresses the height of the bar, and corresponds to the horizontal scale line 421. The scale 424 is provided with a blank space between the scale 424 and the vertical scale line 422 at the left end, and in this blank space, for example, Braille is described.

The degree of completion and the degree of satisfaction of the item 443 of each axis 441 are quantitatively described, and the balance of each item 443 is evaluated.

Here, in each axis 441, a point P for quantitatively describing the degree of perfection and satisfaction is defined by a distance or a ratio from the center O, and when the points P of each axis 441 are connected by a straight line, there are many. A polygon is formed. The polygon can evaluate the degree of perfection and the degree of satisfaction by the ratio to the area of the outermost outer circle, and is expressed as the area expression unit 410. The area expression unit 410 includes an inner region 411 that is inside the polygon and a second boundary region that is a boundary with the background 415.

FIG. 5 is a flowchart for explaining the operation of the display device of the three-dimensional model manufacturing system.
The graph image generation means 41 causes the display operation unit 150 to display the graph selection setting screen (S10). Specifically, the graph image generation means 41 first displays the application selection screen 450 (FIG. 6), confirms that the table input graph application selection button 451 (FIG. 6) is pressed, and then confirms that the graph creation screen 500 (FIG. 7) is pressed. , Fig. 8) is displayed. The graph image generation means 41 selects either a bar graph or a pie chart using the pull-down menu of the graph type selection field 510. FIG. 7 is a screen in which a pie chart is selected in the graph type selection field 510a, and FIG. 8 is a screen in which a bar graph is selected in the graph type selection field 510b. Here, it is assumed that the operator selects a bar graph (FIG. 8) and inputs the number of series "2" and the number of data "3" using the numeric keypad 520.

The graph creation screen 500 includes a combination of the "Cancel" button 521, the "Back" button 522, and the "Next" button 523, and cancels the graph creation (for example, returning to the menu screen). You can return to the screen (for example, the application selection screen 450) and proceed to the next screen.

After S10, the input control means 40 causes the display operation unit 150 to display the X-axis and Y-axis setting screens (S15). That is, the input control means 40 displays the axis information input screen 540 (FIG. 9). The axis information input screen 540 has a check box 541 for displaying the scale line of the X-axis, a check box 542 for displaying the vertical line of the grid, and a check for setting whether to open the braille display area. It has a box 543. Further, the axis information input screen 540 includes an input field 545 for inputting a minimum value and a maximum value of the Y-axis using the numeric keypad 520. Further, the axis information input screen 540 sets a check box 546 for displaying the Y scale line, a check box 547 for displaying the vertical line of the grid, and whether or not to open the braille display area. It is provided with a check box 548 and a "scale interval" input field 549 set by using the numeric keypad 520.

After displaying the X-axis and Y-axis setting screens (axis information input screen 540 (FIG. 9)) of S15, the input control means 40 inputs scale data such as the minimum and maximum values of the Y-axis and the scale interval. Do (S20). After S20, the graph image generation means 41 calls the symbol (foaming pattern table 545 (FIG. 10)) set for each series (S25).

FIG. 10 is an example of a foam pattern table.
The foam pattern table 545 is stored in the non-volatile storage unit 90, and the illustrated foam pattern and color are registered for each series. That is, the three-dimensional model manufacturing system 1000 of the present embodiment is configured so that the foaming pattern and the color are automatically selected according to the series. As for the colors, for example, series 1 is red, series 2 is yellow, series 3 is green, series 4 is dark blue, series 5 is blue, and series 6 is light green. It is assumed that the series 7 is pink and the series 8 is sunflower. In some cases, as in Series 4, there is no foaming pattern.

Returning to the description of FIG. 5, after the processing of S25, the input control means 40 inputs graph data using the graph data input screen 550 (FIG. 11) (S27). As the graph data, for example, the graph data 94 stored in advance in the non-volatile storage unit 90 may be read out without using the graph data input screen 550.

FIG. 11 is a diagram showing an example of a graph data input screen.
The graph data input screen 550 has a data field 551 of the series 1 and a data field 552 of the series 2 for each data label. For example, for label 1, "10" is input for series 1, "8" is input for series 2, "15" is input for series 1, and "5" is input for series 2, and label 3 is labeled. , "12" is input to the series 1, and "10" is input to the series 2.

After S27, the graph image generation means 41 generates an image of the inner region (S30).
FIG. 12 is a flowchart for explaining a generation operation for generating an inner region image.
First, the boundary area / allocation means 21 (FIG. 1) duplicates an image in the boundary area (S31). That is, the boundary area / allocation means 21 duplicates the image of the second boundary area 413 (FIG. 2) and generates the image of the second boundary area 413a (FIG. 13). After S31, the inner region / allocation means 22 (FIG. 1) generates an image of the inner region 411c (FIG. 14), and the generated image is used as a temporary image (S33). After S33, the inner region / allocation means 22 changes the thickness of the second boundary region 413a (S35) and generates an image of the second boundary region 413b (FIG. 15). After S35, the inner region / allocation means 22 changes the color of the second boundary region 413b to white (S37). After S37, the inner region / allocation means 22 superimposes the image of the white region (second boundary region 413b) and the image of the inner region 411c (FIG. 14) (S39), and superimposes the image of the inner region 411d (S39). The image of FIG. 16) is assigned as a backside foam image. That is, the inner region 411d as the back surface foam image is a similar figure smaller than the second boundary region 413a. Then, the process returns to the original routine (FIG. 5).

After S30, the display control means 30 (FIG. 1) causes the bar graph display screen 560 (FIG. 17) to be displayed on the display operation unit 150 (FIG. 17) (S35).

FIG. 17 is an example of a bar graph display screen.
The bar graph display screen 560 is composed of a combination of the bar graph 420 (series 1) described with reference to FIG. 2, a "stop" button 521, a "back" button 522, and a "next" button 523. That is, the operator cancels the graph creation (for example, returning to the menu screen), returns to the previous screen (for example, the graph data input screen 550 (FIG. 11)), and returns to the next screen (for example, the second screen). It is possible to proceed to the graph editing screen 570 (FIG. 19) for serial addition.

After S35, the input control means 40 determines the confirmation of the axis or the symbol (S40). If it is determined that the symbol needs to be reset (design / reset in S40), the display control means 30 causes the display operation unit 150 to display the symbol correction screen 530 (FIG. 18) and corrects the symbol (S45). ).

FIG. 18 is an example of a symbol correction screen.
The design correction screen 530 is a screen for setting a bar pattern and a bar color (background color) for each series. The screen of FIG. 18 is set to "dot pattern" and "red". After S45, the process returns to S30 and regenerates the image of the inner region.

On the other hand, if it is determined that the axis needs to be reset (axis / reset in S40), the display control means 30 returns the process to S15, and the input control means 40 displays the axis information input screen 540 (FIG. 9). Let me. At this time, the display control means 30 can also display the graph editing screen 570 (FIG. 19) to edit lines and add series.

FIG. 19 is a diagram showing an example of a graph editing screen.
The graph editing screen 570 includes a bar graph 425 in which a bar of "series 2" is added to the bar graph 420 of "series 1" described with reference to FIG. 2, and a line type change screen 580. The line type change screen 580 is a screen for changing the line type such as the horizontal scale line 421 and the vertical scale line 422, and is a screen for changing the line type, such as "line color", "line type", "line thickness", and "foam height". You can change the color.

If the axis / symbol is OK (confirmation is OK in S40), the input control means 40 performs the determination input of the graph (S50). If it is necessary to re-input the data (data re-input in S50), the input control means 40 returns the process to S27 and causes the graph data to be input.

On the other hand, if the determination result is that the displayed graph is appropriate (image formation in S50), the image formation control means 50 (FIG. 1) is tertiary with respect to the two-dimensional image formation device 320 and the foaming device 310. Instructs the formation of the original image (S55).

First, the image forming control means 50 uses the two-dimensional image forming apparatus 320 to form a horizontal scale line 421, a vertical scale line 422, an item 423, a scale 424, a second boundary region 413a, and a first boundary region 412 (FIG. 3). ) Is formed on the surface of the heat-expandable sheet in black (FIG. 20 (a)). The table foam image of FIG. 20A includes a braille image 425. Next, the image forming control means 50 forms a mirror image of the back foam image of the inner region 411d (FIG. 16) on the back surface side of the heat-expandable sheet, and forms the mirror image in black (FIG. 20 (b)). .. Further, the image forming control means 50 forms a color image (FIG. 20 (c)) on the surface of the heat-expandable sheet in CMY color.

In FIG. 20 (c), the "yellow" color image is shown by 411e, and the "red" color image is shown by 411f. Further, when forming an image of this color, when the horizontal scale line 421, the vertical scale line 422, the item 423, the scale 424, the second boundary region 413, and the first boundary region 412 are expressed in black, the image formation control means 50 Form an image using all the colors of CMY. Color image formation does not contribute to thermal expansion because it is not black with carbon.

FIG. 21 is a diagram showing an example of a composite image of a front foam image, a front color image, and a mirrored back foam image. Note that FIG. 21 shows the cross-sectional positions of the cross-sectional views of FIGS. 22 and 23. Note that FIGS. 21 and 22 show a “yellow” color image with 411e and a “red” color image with 411f, as in FIG. 20 (c).

Next, the image forming control means 50 irradiates the heat-expandable sheet with near-infrared light using the foaming device 310, and forms a black image (horizontal scale line 421 on the surface side of the heat-expandable sheet). The vertical scale line 422, the item 423, the scale 424, the second boundary region 413, the first boundary region 412, and the braille image 425 are foamed, and the image formation control means 50 ends the process.

FIG. 22 is a cross-sectional view taken along the line AA of the heat-expandable sheet before foaming, and the cross-sectional position is shown in FIG. 21.
The heat-expandable sheet is obtained by laminating a foam layer on one side (front side) of a mount. In the heat-expandable sheet before foaming, an image of the second boundary region 413a and the vertical scale line 422 is formed in black on the surface side, and color images 411e and 411f of the inner region 411 are formed. The second boundary region 413a is wider than the vertical scale line 422. Further, in this heat-expandable sheet, a pattern of the inner region 411d is image-formed on the back surface side. Further, the second boundary region 413a, the vertical scale line 422, and the pattern of the inner region 411d are image-formed at the same density. There is a second boundary region 413b having a different thickness between the second boundary region 413a on the front surface side and the inner region 411d on the back surface side.

FIG. 23 is a sectional view taken along the line AA of the heat-expandable sheet after firing, and FIG. 24 is a perspective view of the heat-expandable sheet after firing.
In the heat-expandable sheet after firing, the foam layer corresponding to the second boundary region 413a and the vertical scale line 422 is not only raised on the front surface side but also the pattern of the inner region 411d in which an image is formed on the back surface side. The foam layer corresponding to the above is also raised on the surface side, and a three-dimensional model (three-dimensional image) is formed. Here, since the pattern of the inner region 411d in which the image is formed on the back surface side expands over time, the rate of change in the height direction is small and the pattern is gentle. On the other hand, since the second boundary region 413a and the vertical scale line 422, which are image-formed on the surface side, expand instantaneously, the rate of change in the height direction is large and the vertical scale line 422 rises sharply. Further, the color image of the inner region 411 is formed on the upper layer of the three-dimensionally foamed foam layer. On the back surface of the heat-expandable sheet, the pattern of the inner region 411d formed in black remains.

As described above, in the three-dimensional model manufacturing system 1000 of the present embodiment, a 2.5D image (three-dimensional modeling) such as a bar graph or a pie chart is formed on a heat-expandable sheet having a heat-expandable layer formed on the surface side (one side). Objects, stereoscopic images) can be formed. Specifically, the three-dimensional model manufacturing system 1000 allocates the first boundary region 412 and the second boundary region 413 (FIG. 2) to the surface side, and the boundary regions 421 and 413, the horizontal scale line 421, and the vertical scale. A line 422, an item 423, a scale 424, and a braille image 425 are formed on a heat-expandable sheet in black containing carbon, an inner region 411 (FIG. 2) is assigned to the back surface side, and the inner region 411 is black containing carbon. An image is formed on a heat-expandable sheet. At this time, the inner region 411d on which the back surface foam image is formed has a similar figure smaller than that of the second boundary region 413. Then, the three-dimensional model manufacturing system 1000 heats the heat-expandable sheet image-formed in black to expand the heat-expandable layer. As a result, in the heat-expandable sheet, the inner region 411 expands the thermal expansion layer toward the front surface side over time from the back surface side, and the first boundary region 421 and the second boundary region 413 immediately thermally expand on the front surface side.
