Description

  The present invention relates to an information processing apparatus and the like that can check the unevenness of a sheet such as wallpaper.

  As a design of a sheet such as a wallpaper, there is one having a textured uneven shape on the surface, such as a stone pattern or a fabric pattern. In order to manufacture such a sheet, for example, an embossed plate having a texture uneven shape formed on the surface thereof is manufactured, and the unevenness is transferred to a sheet of resin or the like.

  In order to form a concavo-convex shape on an embossed plate, it is necessary to create concavo-convex shape data for the plate. This data is referred to as height data (height field data), and is image data in which the height information of the concavo-convex shape is represented by gradation values.

  This height data indicates the uneven shape formed on the sheet surface by the embossed plate. In recent years, a visualization device has been developed to visualize the appearance of a sheet such as wallpaper using such height data. (See Patent Document 1).

  In Patent Document 1, a light source position and a viewpoint position are virtually set with respect to the uneven shape indicated by the height data, and shadows (regions where light from the light source is not directly reflected) and occlusion (visible from the viewpoint) are generated due to the unevenness of the height data. The brightness value of each pixel corresponding to each component of diffuse reflection and specular reflection on the concavo-convex shape of the light irradiated from the light source, and by projecting this, the height data It describes that an image is formed when the uneven shape is viewed under conditions of a predetermined viewpoint position and light source position.

JP 2011-103097 A

  By the way, a wall surface or a covering surface such as a gypsum board on which a sheet such as wallpaper is attached is not necessarily flat and often has irregularities. Such unevenness is referred to as unevenness, but when the sheet is actually attached to a coated surface with unevenness, unevenness that is not present in the sheet may be visible due to unevenness. The appearance of such unevenness varies depending on conditions such as the uneven shape and the uneven shape of the sheet surface. Here, the appearance (difficulty of seeing) of the inland when the sheet is attached is referred to as inland concealment.

  Conventionally, in order to check the unevenness of the sheet, the sheet is actually manufactured and then attached to the coated surface having the unevenness, and the conditions such as the positional relationship between the light source and the viewpoint are changed with the naked eye. I was checking. However, such a method has a problem that requires a lot of labor and cost. In addition, the conditions under which the confirmation work is performed depend on the confirmer, and there are no standards, so evaluations vary. The method of Patent Document 1 does not consider unevenness, and a method for easily and accurately confirming the unevenness concealment of a sheet such as wallpaper has been demanded.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide an information processing apparatus and the like that can easily and accurately confirm the non-land concealing property of a sheet such as wallpaper.

  According to a first aspect of the present invention for solving the above-described problems, height data indicating height information of a covering surface having a convex or concave first non-land portion by a gradation value is used as the first non-land portion. Height data creating means for creating profile data indicating the relationship between the height and the planar shape, and the distance and height from the peripheral edge of the planar shape, and the height information of the uneven shape of the first sheet as gradation values An information processing apparatus comprising: a synthesis unit that adds a tone value of height data for manufacturing an embossed plate and a tone value of height data of the coated surface to create composite height data. is there.

  According to the first invention, the sheet is formed on the coated surface having the uneven portion by the synthetic height data obtained by synthesizing the height data for manufacturing the embossed plate indicating the uneven shape of the sheet and the height data of the coated surface having the uneven portion. Can express the state of sticking. Therefore, it is possible to easily check the unevenness of the sheet without the labor and cost of manufacturing the sheet. In addition, the height data of the covering surface is created using profile data that indicates the relationship between the distance from the peripheral edge of the planar shape of the uneven surface and the height, thereby taking into account the effect of the gap between the covering surface and the sheet. And the state which stuck the sheet | seat on the coating surface can be expressed with high precision. In addition, various uneven parts can be easily expressed by changing parameters such as the height and the planar shape of the uneven part. Further, by setting these parameters in advance and providing a reference for confirmation work, variations in evaluation can be reduced.

  By confirming the non-land concealing property in this way, it is possible to select an optimum one having high non-land concealing property for the height data for producing the embossed plate, and to produce the embossed plate based on the selected height data. Although it takes a relatively large amount of time and cost to manufacture the embossed plate, according to the present invention, it is possible to select height data with a high level of concealment in advance, and thus the risk that the manufactured embossed plate is wasted can be reduced. If a sheet is manufactured by embossing the surface of the sheet using this embossed plate, a sheet having high unevenness concealment and excellent design can be efficiently manufactured.

It is desirable to further have an image creation means for creating an image when the uneven shape indicated by the composite height data is viewed under conditions of a predetermined viewpoint position and light source position.
Using an image obtained by visualizing the composite height data under the visualization conditions such as the predetermined viewpoint position and light source position, the non-landscape concealment when the sheet is attached to the covering surface can be easily confirmed. Confirmation can be easily performed at the viewpoint position and the light source position. In addition, by setting the visualization conditions in advance and providing a reference for the confirmation work, variation in evaluation can be reduced as described above.

Profile data creating means for creating the profile data, wherein the profile data creating means is uneven on the second sheet in a state of being stuck to a covering surface having a convex or concave second uneven portion. The second unevenness is obtained with respect to the height data obtained by subtracting the gradation value of the height data for only the second sheet from the gradation value of the height data indicating the height information of the shape by the gradation value. It is desirable to create the profile data by performing polar coordinate conversion centered on the position of the part and taking the average in the circumferential direction.
Thereby, profile data indicating the influence of the gap generated between the covering surface and the sheet can be created with high accuracy.

For example, the planar shapes of the first non-land portion and the second non-land portion are different.
The planar shape of the non-land portion at the time of creating the profile data and the planar shape of the non-land portion at the time of creating the height data of the covering surface are not necessarily the same. Therefore, the profile data created using the predetermined uneven portion can be applied to the uneven portion having an arbitrary planar shape when creating the height data of the covering surface, and is highly versatile.

A plurality of the profile data are created by changing the height of the second non-land portion, and the height data creating means is configured such that the height of the first non-land portion is the height of the second non-land portion. If any of these is different, it is desirable to interpolate and use a plurality of the profile data.
By interpolating and using profile data according to the height of the uneven surface when creating the height data of the coated surface, the state where the sheet is stuck on the coated surface with high accuracy for the uneven surface of various heights is used. Can express.

In addition, it is preferable that the height data creation unit uses the profile data that differs depending on a direction from the first uneven portion and an uneven shape of the first sheet. It is also desirable to use different profile data depending on the thickness of the first sheet.
When creating height data for the coated surface, use different profile data depending on the direction from the uneven part and the uneven shape of the sheet, or the thickness of the sheet, so that the direction from the pattern and the uneven part of the sheet or the thickness of the sheet Depending on the case, the case where the gap between the covering surface and the sheet is different can be expressed with high accuracy.

The sheet is preferably wallpaper.
The ability to conceal the unevenness is particularly important in the design of the wallpaper, and the effect of applying the present invention to the wallpaper is very large.

  According to a second aspect of the present invention, the computer uses the height data indicating the height information of the covering surface having the convex or concave first uneven portion as a gradation value, the height of the first uneven portion and the planar shape. And the step of creating using the profile data indicating the relationship between the distance from the peripheral edge of the planar shape and the height, and the height for manufacturing the embossed plate showing the height information of the uneven shape of the first sheet by the gradation value And adding the gradation value of the data and the gradation value of the height data of the covering surface to create composite height data.

  According to a third aspect of the invention, height data indicating the height information of the covering surface having the convex or concave first non-landing portion by a gradation value is stored in the computer, and the height and the planar shape of the first non-landing portion. And the step of creating using the profile data indicating the relationship between the distance from the peripheral edge of the planar shape and the height, and the height for manufacturing the embossed plate showing the height information of the uneven shape of the first sheet by the gradation value A program for executing the step of adding the tone value of the data and the tone value of the height data of the coated surface to create composite height data.

  According to a fourth aspect of the present invention, the height data indicating the height information of the covering surface having the convex or concave first uneven portion on the computer is represented by the gradation value, and the height and the planar shape of the first uneven portion. And the step of creating using the profile data indicating the relationship between the distance from the peripheral edge of the planar shape and the height, and the height for manufacturing the embossed plate showing the height information of the uneven shape of the first sheet by the gradation value The recording medium stores a program for executing the step of adding the gradation value of the data and the gradation value of the height data of the coated surface to create composite height data.

(2. Outline of processing of information processing apparatus 1)
An outline of the processing of the information processing apparatus 1 will be described with reference to FIG. FIG. 7 is a flowchart showing an outline of processing of the information processing apparatus 1, and each step in the figure is executed by the control unit 11 of the information processing apparatus 1.

  As shown in FIG. 7, in this embodiment, profile data 5 is created by the information processing apparatus 1 (S1).

  Further, the information processing apparatus 1 creates covering surface height data (S2), and combines the sheet height data 3 and the covering surface height data to create composite height data (S3). Then, an image when the uneven shape of the composite height data is viewed at a predetermined viewpoint position and light source position is created and displayed (S4).

(3. Creation of profile data 5)
The creation of the profile data 5 in S1 will be described with reference to FIG. FIG. 8 is a flowchart showing a flow of creating the profile data 5, and each step in the figure is executed by the control unit 11 of the information processing apparatus 1.

  In S1, the information processing apparatus 1 acquires the sticking sheet height data 6 and the non-sticking sheet height data 7 from the storage unit 12 (S11, S12).

  Then, the information processing apparatus 1 subtracts the non-stick sheet height data 7 from the sticky sheet height data 6 (S13). Here, the gradation value of the pixel at the corresponding position of the non-sticking sheet height data 7 is subtracted from the gradation value of each pixel of the sticking sheet height data 6. An example of the height data after subtraction is shown in FIG.

  The information processing apparatus 1 performs polar coordinate conversion on the height data after the subtraction to calculate the average value in the circumferential direction by creating a profile data 5 (S14).

  The polar coordinate conversion is performed by the distance r from the center of the actual non-land portion shown in FIG. 9B and the circumferential deviation angle θ with respect to the reference, and an example of the result is shown in FIG. 9C. FIG. 9C shows the gradation value with the horizontal axis representing the angle of deviation θ and the vertical axis representing the distance r.

  In S14, the gradation values are averaged between the deflection angles θ of FIG. Thus, by taking the average value in the circumferential direction, the error is eliminated, and the profile data 5 is created by converting this average value into a height. It is also possible to take a weighted average if necessary. In the present embodiment, the profile data 5 is created for the outer portion from the periphery of the actual non-land portion shown by a in FIG. Further, as shown in FIG. 9D, a plurality of profile data 5 are created by changing the height of the actual uneven portion. In FIG. 9D, the height of the actual uneven portion corresponds to the height of the profile data 5 at the position where the distance from the periphery is “0”.

(4. Creation of coated surface height data)
Next, the flow of creating the coated surface height data in S2 will be described with reference to FIG. FIG. 10 is a flowchart showing a flow of creating the covering surface height data, and each step in the figure is executed by the control unit 11 of the information processing apparatus 1.

  In the present embodiment, the user first inputs the height of the uneven portion 42 shown in FIG. 11A as a parameter. The information processing apparatus 1 accepts this input (S21) and stores the input height in a RAM or the like.

  Further, the user selects the planar shape data 4 of the non-land portion 42 from the planar shape data 4 (see FIG. 4). The information processing apparatus 1 accepts the selection of the planar shape data 4 and acquires the selected planar shape data 4 (S22). Here, it is assumed that square plane shape data 4 is selected as shown in FIG.

  At this time, since the shape of the inclined portion on the side of the non-land portion 42 shown in FIGS. 11A and 11B (corresponding to the gap 44 in FIG. 3A) is not determined, the information processing apparatus 1 Then, a slope is given to the uneven portion 42 based on the profile data 5, and covering surface height data is created (S23).

  In S23, for example, as shown in FIG. 11 (c), for each pixel (pixel shown in black) other than the non-land portion 42 of the plane shape data 4 acquired in S22, from the periphery of the flat shape of the non-land portion 42. The distance R is calculated. Then, the height corresponding to the distance R is acquired using the profile data 5, and this is converted into a gradation value to obtain the gradation value of each pixel. On the other hand, the gradation value of the pixel of the non-land portion 42 is obtained by converting the height acquired in S21 into the gradation value, and thereby, the covering surface height data is created.

  The distance R is a distance between the pixel and a location on the periphery closest to the pixel, and can be calculated using a known distance conversion method based on the binary image of the planar shape data 4. As a specific distance conversion method, there is a method called sequential distance conversion, etc., but simply described, the value of a pixel other than a predetermined region (non-land portion 42 in the present embodiment) of a binary image is set as the pixel. Is replaced with the distance from the nearest pixel to the pixel in the predetermined area.

  For example, based on the binary image of the planar shape data 4, the pixel of the non-land portion 42 is “0” and other pixels are arbitrary values (here, “10” as partially shown in FIG. 12A). The distance between the pixels adjacent in the vertical and horizontal directions and the distance between the pixels adjacent in the diagonal direction are set to predetermined values. Here, it is assumed that 1 and √2, respectively.

  Then, as shown in FIG. 12B, a distance image is created by replacing the values of the pixels other than the non-land portion 42 with the distance to the nearest “0” pixel (the pixel of the non-land portion 42). For example, the value of the pixel indicated by c in the figure is replaced with the distance R (= 1 + √2) to the nearest “0” pixel. In this way, the distance R is calculated for each pixel other than the non-land portion 42 of the planar shape data 4.

  In the present embodiment, a plurality of profile data 5 are created by changing the height of the actual uneven portion, but the profile data 5 used in S23 is the same as the height of the uneven portion 42 input in S21. If there is profile data 5 created in the actual uneven part of the height, it is desirable to use it.

  On the other hand, when the height of the uneven portion 42 input in S21 is different from any of the actual uneven portions at the time of profile data creation, as schematically shown by the dotted line in FIG. The plurality of profile data 5 can be interpolated, and the height at the position where the distance from the periphery is “0” can be used in accordance with the height of the non-land portion 42 (see b in the figure) input in S21. However, the present invention is not limited to this, and the predetermined profile data 5 can be used by being deformed in the height direction of the graph of FIG.

  FIG. 13 is an example of the covering surface height data 8 created as described above, and is image data indicating the height information of the covering surface 41 having the uneven portion 42 in a gray scale of 256 gradation values.

(5. Creation and visualization of synthetic height data)
In S3 (see FIG. 7), the information processing apparatus 1 uses the gradation values of the sheet height data 3 and the gradation values of the covering surface height data 8 created in S2 between pixels at corresponding positions. Composite height data is created by addition. The composite height data is image data that indicates the height information of the uneven shape of the sheet surface when the sheet 43 is attached to the covering surface 41 and covered as shown in FIG.

  In S4 (see FIG. 7), the information processing apparatus 1 accepts user input of visualization conditions such as the light source position and the viewpoint position, and the uneven shape indicated by the composite height data is viewed at the predetermined viewpoint position and light source position. Are generated and displayed on the display unit 17. FIG. 14A shows an example of this image.

  In order to create an image, for example, a technique as described in JP 2011-103097 A may be used. In JP 2011-103097 A, a light source position and a viewpoint position are virtually set with respect to height data representing the height information of the concavo-convex shape by the gradation value of each pixel, and a shadow ( Luminance of each pixel according to each component of diffuse reflection and specular reflection on the concavo-convex shape of the light emitted from the light source, taking into account the light from the light source that is not directly reflected) and occlusion (region that is not visible from the viewpoint) It is described that a value is obtained and projected and converted to create an image when the uneven shape of height data is viewed at a predetermined viewpoint position and light source position. However, the method of visualizing by setting the viewpoint position and the light source position is not limited to this, and various known methods can be used. The visualization conditions input at this time may include the angle, intensity, and type (parallel light source, spotlight, etc.) of the light source.

  The process of S4 can be performed for a plurality of light source positions and visualizing conditions of viewpoint positions, and images can be created when viewed from various viewpoints and light source positional relationships. Further, the same processing is performed on each of the composite height data created using the plurality of covering surface height data 8 having different planar shapes of the non-land portion 42, thereby improving the non-land concealment property of the seat 43 for various non-land surfaces. It is possible to confirm and comprehensively evaluate the uneven concealment of the sheet 43. FIG. 14B is an example in which the planar shape of the non-land portion 42 is a star shape, a square shape, and a circle in order from the left. By using such an image, the non-land concealment property of the sheet 43 is evaluated, and the sheet height data 3 of the sheet 43 having high non-land concealment property and excellent design properties can be selected.

(6. Embossed plate manufacturing system 10)
FIG. 15 is a diagram showing an embossed plate manufacturing system 10 according to an embodiment of the present invention. The sheet height data 3 whose non-land concealment property is evaluated in the image created by the information processing apparatus 1 as described above is embossed. It is used for manufacturing an embossed plate by the plate manufacturing apparatus 9.

  FIG. 16 shows an example of the embossed plate manufacturing apparatus 9, which uses the sheet height data 3 to perform embossed engraving with a textured uneven shape on the embossed plate cylinder 100. As shown in the figure, the embossed plate manufacturing apparatus 9 includes a computer 91, an engraving machine 93, a support base 101, and a rotation drive unit 104.

The embossing plate cylinder 100 is moved in the direction of the rotation axis (direction AA in the figure). The rotation driving unit 104 rotates the embossed plate cylinder 100 supported by the support bases 101 and 101 around the direction of the rotation axis AA in accordance with an instruction input from the computer 91.

  Accordingly, the engraving machine 93 engraves the metal or resin embossed plate cylinder 100 at a depth according to the texture uneven shape indicated by the sheet height data 3 to form the texture uneven shape.

  The engraving machine 93 may be of a type using a laser or the like instead of the engraving blade 933. In this case, the engraving machine 93 may use a scanning unit, a laser oscillator, and an optical unit instead of the driving unit 932 and the engraving blade 933 shown in FIG. In the same manner as described above, the laser beam having the output value based on the sheet height data 3 is irradiated through the optical unit while moving the embossing cylinder 100 or the optical unit. This also makes it possible to form a textured uneven shape on the embossed cylinder 100.

  On the other hand, FIG. 17 shows another example of the embossing plate manufacturing apparatus. In the embossing plate manufacturing apparatus 9A of FIG. 17, the textured uneven shape is formed on the embossing plate cylinder 200 by using an etching method based on the sheet height data 3.

  Here, the sheet height data 3 is binarized using a predetermined gradation value as a threshold value, and control is performed so that the laser is turned on / off with the threshold value as a boundary. Thereby, a laser beam is irradiated to a predetermined position of the embossed plate cylinder 200 coated with the resist layer, and an exposure process for forming a pattern including an exposed portion and a non-exposed portion is performed. As the resist layer, either a positive resist or a negative resist can be used. In the case of a positive resist, the resist layer in the exposed area is gelled by the exposure process. In the case of a negative resist, the resist layer in the exposed portion is cured by the exposure process.

  After the exposure processing is completed, the embossing plate cylinder 200 is developed and washed with a developing device (not shown), and an exposed portion (in the case of a positive resist) or a non-exposed portion (in the case of a negative resist) of the resist layer is removed. Then, a resist layer pattern is formed.

  Thereafter, when a corrosive liquid is applied to the embossed plate cylinder 200 by the corrosive device 98, the metal surface portion exposed by the removal of the resist layer is corroded and recessed, and an uneven shape corresponding to the pattern is formed. Subsequently, a cleaning process is performed to remove the remaining resist layer.

  Thereafter, the resist layer is again coated on the surface of the embossed cylinder 200, and the above processing is repeated while changing the above threshold value. By performing this multiple times, it is possible to form a plurality of concavo-convex shapes on the surface of the embossing plate cylinder 200, thereby forming a textured concavo-convex shape on the surface of the embossing plate cylinder 200. An appropriate value may be set in advance as the threshold value.

  Further, as a means for forming a resist layer pattern by a laser beam, it is necessary to draw directly on the embossed cylinder 200 coated with the resist layer (burn out the resist layer) and to remove the resist layer by development processing or cleaning processing. There are laser plate machines that do not, and are often used. The configuration of the embossed plate manufacturing apparatus in this case is the same as that of the embossed plate manufacturing apparatus 9A except that a developing device or the like is not required.

  At this time, the pattern exposure apparatus 96 performs the same control as described above, irradiates a predetermined position of the embossing plate cylinder 200 coated with the resist layer with a laser beam, burns and removes the resist layer in the exposed portion, and removes the resist layer. Form a pattern. As a laser oscillated by the laser oscillator 962, a YAG laser or a fiber laser can be used.

  Thereafter, the same corrosion treatment as described above is performed to form an uneven shape corresponding to the pattern on the embossed plate, and then the remaining resist layer is removed by the cleaning treatment. By repeating the resist layer coating, the exposure process, the corrosion process, and the cleaning process a plurality of times while changing the threshold value, it is possible to form a plurality of concavo-convex shapes on the surface of the embossed plate cylinder 200.

  FIG. 18 shows still another example of the embossing plate manufacturing apparatus. The embossing plate manufacturing apparatus 9B of FIG. 18 manufactures a photomask 97 based on the sheet height data 3, and uses this to etch the embossing plate cylinder 200. By doing so, a textured uneven shape is formed.

  The embossed plate manufacturing apparatus 9B includes a pattern exposure apparatus 96, corrosion apparatuses 98 and 98a, an embossed plate exposure apparatus 99, a support base 101, and a rotation drive unit 104 in addition to the computer 91 similar to the above. An embossed cylinder 200 coated with a resist layer is attached to the support base 101.

  Here, the pattern exposure device 96 and the corrosion device 98 are used in the manufacturing stage of the photomask 97, and the embossed plate is manufactured by the embossing plate exposure device 99 and the corrosion device 98a using the photomask 97.

  In the photomask 97, a light shielding film 972 is formed on a substrate 973, and a resist layer 971 is further coated thereon. With respect to the photomask 97 in such a state, the pattern exposure apparatus 96 performs exposure control according to the threshold value of the sheet height data 3 by the same method as described with reference to FIG. Part and non-exposed part are formed. Thereafter, development and washing are performed to remove an unnecessary resist layer to form a resist layer pattern. In the portion where the resist layer is removed, the light shielding film 972 is exposed.

  Subsequently, when a corrosive liquid is applied by the corrosive device 98, the exposed portion of the light shielding film 972 is removed by corrosion. Thereafter, when the remaining resist layer is removed by the cleaning process, a photomask 97 in which the pattern of the light shielding film 972 is formed on the substrate 973 is manufactured.

  The required number of photomasks 97 are manufactured while changing the threshold value, and each is used for exposure to the embossing plate cylinder 200. That is, the embossed plate cylinder 200 coated with the resist layer is covered with a photomask 97 and exposed by an embossed plate exposure apparatus 99, whereby an exposure portion according to the pattern of the light shielding film 972 formed on the photomask 97 and A non-exposed portion is formed.

  Subsequently, an unnecessary resist layer is removed by performing development and cleaning processes similarly to the example of FIG. 17, and a pattern of the resist layer is formed on the embossed plate cylinder 200. Thereafter, when corrosion and cleaning processes are performed using a corrosive device 98a or a cleaning device (not shown), as described above, irregularities are formed on the surface of the embossed plate cylinder 200, and the remaining resist layer is removed.

  The surface of the embossed plate cylinder 200 is changed by replacing the photomask 97 and repeating the processes of resist layer coating, exposure, development, cleaning (removal of unnecessary resist layer), corrosion, and cleaning (removal of remaining resist layer). A plurality of concavo-convex shapes can be formed on the surface of the embossing plate cylinder 200.

  According to these embossed plate manufacturing apparatuses 9, 9 </ b> A, 9 </ b> B, it is possible to form textured uneven shapes on the embossed plate cylinders 100, 200 based on the sheet height data 3. Further, a sheet such as wallpaper can be manufactured by embossing a desired sheet using the embossed cylinders 100 and 200. The material of the sheet is determined according to the application, and for example, paper, resin, synthetic leather, or the like can be used.

  As described above, in the present embodiment, the combined height data obtained by combining the seat height data 3 and the covering surface height data 8 can express the state in which the sheet 43 is attached to the covering surface 41 having the uneven portion 42. . Therefore, it is possible to easily confirm the uneven concealment of the sheet 43 without labor and cost for manufacturing the sheet 43. Further, the gap between the covering surface 41 and the sheet 43 is created by creating the covering surface height data 8 using the profile data 5 indicating the relationship between the distance from the peripheral edge of the planar shape of the non-land portion 42 and the height. The state where the sheet 43 is adhered to the covering surface 41 can be expressed with high accuracy in consideration of the influence of 44. In addition, by changing parameters such as the height and planar shape of the non-land portion 42, various non-land portions 42 can be easily expressed. Further, by setting these parameters in advance and providing a reference for confirmation work, variations in evaluation can be reduced.

  By confirming the non-land concealing property in this way, it is possible to select an optimum one having high non-land concealing property with respect to the seat height data 3 for producing the embossed plate, and to produce the embossed plate based on the selected height data. Although it takes a relatively large amount of time and cost to manufacture the embossed plate, according to the present invention, it is possible to select height data with a high level of concealment in advance, and thus the risk that the manufactured embossed plate is wasted can be reduced. If a sheet is manufactured by embossing the surface of the sheet using this embossed plate, a sheet having high unevenness concealment and excellent design can be efficiently manufactured.

  Further, in this embodiment, the non-land concealment property when the sheet 43 is attached to the covering surface 41 is easily confirmed using an image obtained by visualizing the composite height data under a visual condition such as a predetermined viewpoint position or light source position. It is possible to check easily at various viewpoint positions and light source positions by changing the visualization condition. In addition, by setting the visualization conditions in advance and providing a reference for the confirmation work, variation in evaluation can be reduced as described above.

  Further, by creating the profile data 5 by the method described in S <b> 1, the profile data 5 indicating the influence of the gap 44 generated between the covering surface 41 and the sheet 43 can be created with high accuracy.

  In the present embodiment, the planar shape of the actual non-land portion at the time of creating the profile data is a circle, and the planar shape of the non-land portion 42 is a square when the covering surface height data 8 is created. In this way, the planar shape of the actual non-land portion and the non-land portion 42 need not be the same (of course, may be the same), and the profile data 5 created using the predetermined actual non-land portion is used as the covering surface height. It can be applied to the uneven portion 42 having an arbitrary planar shape when creating the data 8, and is highly versatile.

  Further, when the covering surface height data 8 is created, if the height of the non-land portion 42 input in S21 is different from any of the actual non-land portions at the time of profile data creation, a plurality of profile data 5 By interpolating and using, the state where the sheet 43 is stuck on the covering surface 41 can be expressed with high accuracy for the uneven portion 42 of various heights.

  It should be noted that the way in which the gap 44 is formed changes depending on the rigidity of the sheet 43, and when the rigidity is low, the sheet 43 is attached along the non-land portion 42, so the width of the gap 44 is small. The width of the gap 44 is increased. Therefore, the profile data 5 may be generated using various sheets and stored in the storage unit 12 while changing various physical property values related to the sheet rigidity, such as the sheet thickness, uneven shape, material, and strength. desirable. An example thereof is profile data 5 indicated by a dotted line or a chain line in FIG. 19A, and a case (dotted line) where the width of the gap 44 is increased by the profile data 5 such as when the thickness of the sheet 43 is large, or the thickness of the sheet 43. A case where the width of the gap 44 is small (a chain line) is expressed, for example, when is small. In S2, by inputting a physical property value such as the thickness of the sheet 43 as a parameter, different profile data 5 is used according to the thickness of the sheet 43, and appropriate profile data 5 according to the rigidity of the sheet 43 is applied. Is also possible.

  Further, depending on the uneven shape of the sheet 43, that is, the handle of the sheet 43, a gap 44 having a large width is easily formed in the lateral direction from the uneven portion 42, but the width of the gap 44 is reduced in the longitudinal direction. Anisotropy may occur in the method of forming. Therefore, according to the direction from the non-land portion 42 of the planar shape data 4 and the uneven shape of the seat height data 3, for example, different profile data 5 can be used from the profile data 5 shown in FIG. As a result, the case where the gap 44 is formed as described above can be expressed with high accuracy.

  Moreover, although the case where the uneven part 42 is convex shape was demonstrated in this embodiment, in the case of the concave uneven part 45 (refer FIG.3 (b)), the sticking at the time of making an actual uneven part concave is used. The profile data 5 may be created using the landing sheet height data 6. As shown in FIG. 3B, in the case of the concave non-land portion 45, a gap 44 is formed inside the non-land portion 45. For example, the profile data 5 is created for the inner portion from the periphery of the actual non-land portion. In S <b> 2, the profile data 5 can be used to give the inclination of the inclined portion inside the non-land portion 45 shown in FIG. 19B.

  Furthermore, examples of the sheet are not limited to wallpaper having a wall surface, a gypsum board, or the like as a covering surface, but may be a ceiling material having a foamable resin layer having a ceiling, a gypsum board, or the like as a covering surface. In addition, it may be a decorative sheet that is affixed to a coated surface of a base material made of wood or resin and used as a decorative board. However, the ability to conceal the unevenness is particularly important in the design of the wallpaper, and the effect of applying the present invention to the wallpaper is very large.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these are naturally within the technical scope of the present invention.
