Description

  The present invention relates to a pattern matching program capable of printing a continuous pattern such as a pattern pattern or a large pattern such as a floral pattern on a surface of a continuous sheet body having a three-dimensional shape such as clothes by using digital printing. .

  In general, clothes with patterns (patterns, patterns, patterns, etc.), for example, many clothes have a single pattern (unit) smaller than the size of the clothes, and the same pattern is repeatedly drawn on one piece of clothes. It is. In addition, since the same pattern is repeatedly drawn on one piece of clothing, a single pattern is arranged side by side on the fabric, for example, a rectangle or a parallelogram, so that the fabric can be filled without gaps. The fabric with the pattern thus formed is cut by adding a seam allowance to the shape of the pattern (parts), and stitched together to create clothes. However, since the fabric is cut off at the portion between the outlines of the adjacent paper patterns at the time of cutting, the pattern of the cut-off portion is lost. For this reason, the conventional garment with a handle is not connected at the stitched portions of a plurality of cut pieces, and there is room for improvement in design.

Here, as a technique for assigning a pattern to a cloth of a mold piece such as clothes, there is a technique described in Patent Document 1, for example.
JP-A-8-158132

  Patent Document 1 discloses a mold piece edit pattern matching program that can divide a picture spanning a plurality of mold pieces and assign it to a mold piece that draws the divided picture pieces. This mold piece edit pattern matching program is corrected by the pattern correction means so that when a partial gap portion is generated between at least two mold pieces displayed on the display means, the pattern is extended in the gap portion. Since the corrected pattern is allocated to each mold piece by the pattern allocating means, it is possible to obtain an effect that, when the mold pieces are sewn together, the pattern straddling the two mold pieces can be seen without a sense of incongruity. .

  However, in the technique described in Patent Document 1, when a partial gap portion is generated between two mold pieces, the gap portion is filled by copying the pattern immediately before the gap portion in units of pixels. However, it is not certain whether the pattern of the gap portion and the patterns on both sides of the gap portion are completely continuous. In particular, the technique described in Patent Document 1 divides a pattern spanning two mold pieces, with a line connecting intermediate positions of adjacent finish lines of the two mold pieces as a boundary. Since the patterns on both sides are stretched and copied to the gaps of each mold piece, even if the gaps can be filled with the patterns, it is unclear whether such a pattern will be a naturally continuous pattern. .

  Here, for example, in order to solve the lack of a pattern in a gap portion such as a dart portion of clothes, the present inventors prepared a substantially rectangular pattern as a pattern for the front body and the back body, respectively, When the pattern is used up side by side, the missing part disappears in the stitched parts on both bodies, so when stitching using these two patterns, it is possible to create a clothing that connects all the patterns seamlessly. Focused on. However, the clothes created in this way are square cylinders and are not realistic. Clothes have a complicated three-dimensional shape to match the human body, and there are many changes in the pattern. Therefore, even if the above idea is adopted as it is, it is not possible to create a clothes with an actual three-dimensional shape, and it is difficult to create clothes without a pattern cut using existing fabric. Therefore, the present inventors have further found that if a fabric with a pattern distorted in advance so that the pattern is connected after sewing by using digital printing, satisfactory clothes can be realized in both the pattern and the shape, As a result of intensive research and trial and error, the present invention was conceived.

  Therefore, the present invention can provide a desired pattern without any break to a continuous sheet body such as clothes having an arbitrary three-dimensional shape, and can realize high design quality from both the pattern and shape aspects. The issue is to provide a pattern matching program.

The pattern matching program according to claim 1 uses a plurality of planar mold pieces having a predetermined outline to provide a predetermined pattern on the surface of a continuous sheet body formed in a three-dimensional shape corresponding to the mold pieces. It is for applying continuously without a gap. The pattern matching program causes the computer to execute a data preparation procedure, a mold piece arrangement procedure, a deformation procedure, a pattern assignment procedure, an association procedure, and a reverse deformation procedure. In the data preparation procedure, outline data of each of a plurality of mold pieces to be used, joint line information regarding the outline data, and mesh division information obtained by dividing an inner region of the outline of the mold piece into a number of meshes. prepare. Further, in the mold piece arrangement procedure, the plurality of mold pieces are arranged side by side so that the area of the gap formed between the outlines of the plurality of mold pieces is reduced. Furthermore, in the deformation procedure, the outer shape line of the mold piece is moved closer by deforming the mesh inside the mold piece so as to fill the gap formed between the outline lines of the plurality of mold pieces , Corresponding outlines of a plurality of mold pieces are joined to each other to form a joint line, and an integral region is formed inside the outline lines of the plurality of mold pieces integrated with the plurality of mold pieces. On the other hand, the strain of the mesh deformed inside the mold piece by the close movement of the outline of the mold piece is dispersed throughout the mold piece . Further, in the pattern applying procedure, a series of patterns is applied to the whole of the integrated area inside the outline of the plurality of mold pieces that has been moved by deformation of the mesh to become an integrated area without a gap. . Further, in the associating procedure, the coordinates of the constituent elements of the series of patterns given to the whole of the integrated region inside the outlines of the plurality of mold pieces, and after the movement of each of the deformed meshes Associate coordinates. In the reverse deformation procedure, each of the deformed meshes is returned to the coordinate position before the movement, the outline of each mold piece is returned to the position before the movement, and the associated meshes are associated with each of the deformed meshes. By moving each component of the handle to the coordinate position before the movement of the corresponding mesh, the same gap as before the movement is formed between the outlines of the plurality of mold pieces returned to the position before the movement. In addition, the pattern is deformed and copied so as to correspond to the deformation of the mesh for each of the plurality of mold pieces returned to the position before the movement .

The pattern matching program according to claim 2 uses a plurality of planar mold pieces having a predetermined outline, and applies a predetermined pattern to the surface of a continuous sheet formed in a three-dimensional shape corresponding to the mold pieces. It is for applying continuously without a gap. The pattern matching program causes the computer to execute a data preparation procedure, a mold piece arrangement procedure, a deformation procedure, a pattern assignment procedure, an association procedure, and a reverse deformation procedure. In the data preparation procedure, outline data of each of a plurality of mold pieces to be used, joint line information regarding the outline data, and mesh division information obtained by dividing an inner region of the outline of the mold piece into a number of meshes. prepare. Further, in the mold piece arrangement procedure, the plurality of mold pieces are arranged side by side so that the area of the gap formed between the outlines of the plurality of mold pieces is reduced. Further, in the deformation procedure, the outer shape line of the mold piece is moved by deforming the mesh inside the mold piece so as to fill the gap formed between the outer shape lines of the plurality of mold pieces. Further, in the pattern application procedure, a series of patterns is applied to the entire area inside the outline of the plurality of mold pieces that have been moved by deformation of the mesh to form an integrated area without a gap. Further, in the associating procedure, the coordinates of the constituent elements of the series of patterns given to the entire area inside the outline of the plurality of mold pieces and the coordinates after the movement of each of the deformed meshes are obtained. Associate. In the reverse deformation procedure, each of the deformed meshes is returned to the coordinate position before the movement, the outline of each mold piece is returned to the position before the movement, and the associated meshes are associated with each of the deformed meshes. Each component of the handle is moved to the coordinate position before the movement of the corresponding mesh. In the pattern matching program according to claim 2, the deformation procedure further includes a joining line joining procedure and a dispersion procedure. In the joining line joining procedure, the mesh vertices at the corresponding positions across the gap on the joining line of the outer shape line of the adjacent mold pieces are moved by a predetermined ratio to approach each other, and the corresponding joining lines are moved. Join. In addition, the dispersion procedure may be arranged such that each time the vertexes of the mesh are moved by a predetermined ratio in the joining line joining procedure, the distortion of the mesh that is deformed inside the mold piece by the movement of the vertex of the mesh is changed over the entire mold piece. To disperse.

The pattern matching program according to claim 3 uses a predetermined pattern on the surface of a continuous sheet formed in a three-dimensional shape corresponding to the mold piece by using a plurality of planar mold pieces having a predetermined outline. It is for applying continuously without a gap. The pattern matching program causes the computer to execute a data preparation procedure, a mold piece arrangement procedure, a deformation procedure, a pattern assignment procedure, an association procedure, and a reverse deformation procedure. In the data preparation procedure, outline data of each of a plurality of mold pieces to be used, joint line information regarding the outline data, and mesh division information obtained by dividing an inner region of the outline of the mold piece into a number of meshes. prepare. Further, in the mold piece arrangement procedure, the plurality of mold pieces are arranged side by side so that the area of the gap formed between the outlines of the plurality of mold pieces is reduced. Further, in the deformation procedure, the outer shape line of the mold piece is moved by deforming the mesh inside the mold piece so as to fill the gap formed between the outer shape lines of the plurality of mold pieces. Further, in the pattern application procedure, a series of patterns is applied to the entire area inside the outline of the plurality of mold pieces that have been moved by deformation of the mesh to form an integrated area without a gap. Further, in the associating procedure, the coordinates of the constituent elements of the series of patterns given to the entire area inside the outline of the plurality of mold pieces and the coordinates after the movement of each of the deformed meshes are obtained. Associate. In the reverse deformation procedure, each of the deformed meshes is returned to the coordinate position before the movement, the outline of each mold piece is returned to the position before the movement, and the associated meshes are associated with each of the deformed meshes. Each component of the handle is moved to the coordinate position before the movement of the corresponding mesh. In the pattern matching program according to claim 3 , the deformation procedure further includes a joining line joining procedure and a spring calculation procedure. In the joining line joining procedure, the vertexes of the meshes at the corresponding positions across the gap on the joining line of the outer shape line of the adjacent mold piece are moved by a predetermined ratio so as to approach each other, and the corresponding joining lines are moved. Join. Further, in the spring calculation procedure, each time the vertexes of the mesh are moved by a predetermined ratio in the joining line joining procedure, the side extending from the vertex of the mesh expanded by the movement of the mesh vertex returns to the state before the stretching. Thus, the vertexes of the sides connected to both ends of the side are moved so that the distortion of the side is dispersed throughout.

The pattern matching program according to claim 4 further uses, as the mold piece, a pattern for the front body and a pattern for the back body for creating clothes. Further, the mold piece arrangement procedure defines a right end line, a left end line and an upper end line for the plurality of patterns for the front body arranged closely, and a right end line for the plurality of patterns for the back body arranged closely.

  Hereinafter, the best mode for carrying out the present invention (hereinafter referred to as an embodiment) will be described. FIG. 1 conceptually shows the processing of a pattern matching program according to an embodiment of the present invention. First, the pattern matching program of the present embodiment can be applied to a pattern matching system for clothes, for example, a dress for women shown in FIG. Specifically, as shown in FIG. 1A, the pattern matching program according to the present embodiment includes a plurality of patterns (pattern pieces) 11, 12, 13 for the front body and a back body for creating clothes. A plurality of patterns 21, 22, 23, 24 are arranged as close as possible (closely arranged), and in that state, a predetermined pattern (such as a lattice pattern) 10A is placed on a set of patterns 11-13 for the front body, The computer is caused to execute a process of placing the predetermined pattern 10B on the back patterns 21-24. Even in this state, the outlines between the adjacent paper patterns 11 to 13 and 21 to 24 are mostly in close contact except for the gap portion D between the paper patterns 11 to 13 and 21 to 24. As a whole, the range of missing patterns can be greatly reduced. However, even in this case, the gaps between all the patterns 11 to 13 and 21 to 24 are not filled, and the pattern of the gap portion D is missing. In addition, a large gap portion S is still formed between the front body patterns 11-13 and the back body patterns 21-24 (between the left and right suture lines and between the suture lines at the shoulder positions), The pattern of this part is largely missing.

  Therefore, as shown in FIG. 1A, the pattern matching program according to the present embodiment uses the patterns 10A and 10B of the gap portions D and S remaining between the patterns 11 to 13 and 21 to 24 as the corresponding patterns 11 to 11. 13 and 21 to 24 are made to run in the direction of the arrow in the figure. Then, as shown in FIG.1 (b), it deform | transforms so that the pattern of the clearance gap parts D and S between the pattern papers 11-13, 21-24 may be pushed into the inside of the corresponding pattern papers 11-13, 21-24 respectively. The patterns 10A and 10B are not left in the gap portions D and S. In addition, when darts, such as a side dart, exist in a pattern paper, the same process is performed also in the clearance gap part of this dart. In this way, when the clothes are created using the patterns 11 to 13 and 21 to 24 on which the patterns 10A and 10B are placed without being lost, the clothes are deficient in darts or stitched portions between the front body and the back body. No matter what direction it is seen from 360 degrees, the clothes will be seamless.

  FIG. 2 shows a series of processes (procedures) of the pattern matching program according to the embodiment of the present invention. As shown in FIG. 2, the pattern matching program according to the present embodiment causes a computer to execute a series of steps from STEP 10 to STEP 90. Specifically, in the data preparation procedure of STEP 10, outline data is prepared for each of a plurality of patterns to be used by a data creation program such as an apparel design system, and joining line information (stitching lines) about the outline data is used. Information). Further, in the data preparation procedure, dart information is added to the position where the dart should be set in the outline data. Furthermore, in the data preparation procedure, mesh division information obtained by dividing the inner region of the outline of the mold piece into a large number of meshes is prepared. The mesh division information is data related to a minute polygon mesh (for example, a triangular mesh) that is automatically generated over the entire inner area of each pattern by a predetermined mesh generation algorithm, and is automatically generated using a mesh generation algorithm using a Delaunay network. Can be generated. The finer the mesh generation inside the paper pattern, the smaller the distortion of the pattern after deformation and reverse deformation, which will be described later, and the smoother deformation can be performed so that the deformation boundary is not noticeable. The design of clothes as a product can be improved. The data creation program used in this data preparation procedure can be configured separately from the pattern matching program of the present embodiment, but can also be implemented as a series of configurations.

  Next, in the mold piece arrangement procedure (part arrangement procedure) of STEP 20, as shown in FIG. 3A, the area of the gap formed between the outlines of the plurality of patterns 11 to 13 and 21 to 24 is the smallest. A plurality of pattern papers 11 to 13 and 21 to 24 are arranged in parallel. Here, in the data preparation procedure, the outline data is prepared for the three patterns 11, 12, 13 for the front body and the four patterns 21, 22, 23, 24 for the back body. . The stitching line information is stitching line data added with respect to the position (range) to be stitched out of each outline data. In the front body, outline lines other than the cuffs, the collar and the lower end of the pattern 11 are used. Becomes a stitching line, and outlines other than the cuff portions and the lower end of the patterns 12 and 13 become stitching lines. In the back body, outlines other than the cuffs, the collar part, and the lower end of the paper pattern 21 and the paper pattern 22 become stitch lines, and outlines other than the cuff parts and the lower end of the pattern papers 23 and 24 become suture lines. Then, in the mold piece arrangement procedure, the front body patterns 11, 12, 13 are intimately contacted with each other by stitching lines other than the gap portion D, while the gap portions of the outlines (stitching lines) of the pattern papers 11, 12, 13 are used. A predetermined gap is formed in D. Similarly, the patterns 21, 22, 23, and 24 of the back body are in close contact with each other with a suture line other than the gap part D, while the gap part D of the outline (sew line) of the pattern papers 21, 22, 23, and 24 is used. A predetermined gap is formed in. As in this embodiment, the plurality of patterns 11 to 13, 21 to 24 are arranged in parallel so that the area of the gap formed between the outlines of the plurality of patterns 11 to 13, 21 to 24 is minimized. Arrangement is most preferable from the standpoint of pattern matching. However, even if the area of the gaps for clothing three-dimensionalization such as the gap portions D and S is not the minimum, the patterns should be arranged adjacent to each other so as to be smaller than in the case of normal pattern arrangement. Thus, a certain pattern matching effect can be obtained.

  Further, in the mold piece arrangement procedure, a pattern arrangement area for arranging a pattern is instructed (defined) as a pattern arrangement area definition procedure. Specifically, first, the right end line R1, the left end line L1, and the upper end line U1 are instructed for the plurality of patterns for the front body 11-13 that are closely arranged, and the plurality of patterns 21-24 for the back body. Similarly, the right end line R2, the left end line L2, and the upper end line U2 are indicated. A region surrounded by the right end line R1, the left end line L1, and the upper end line U1 of the plurality of patterns 11-13 for the front body is defined as a rectangular pattern arrangement region 10X for the front body. Similarly, a region surrounded by the right end line R2, the left end line L2, and the upper end line U2 of the plurality of patterns 21 to 24 for the back front body is defined as a rectangular pattern arrangement region 10Y for the back body. At the same time, in the pattern arrangement region definition procedure, as shown by arrows C1, C2, and C3 in FIG. 3B, the suture lines on the left and right sides and the upper end side (shoulder position) of the front body and the left and right sides and the upper end of the rear body Corresponding to the side (shoulder position) suture line being sewn, the right end line R1 of the pattern arrangement region 10X for the front body, the left end line L2 of the pattern arrangement region 10Y for the back body, and the pattern for the front body The left end line L1 of the arrangement area 10X, the right end line R2 of the pattern arrangement area 10Y for the back body, the upper end line U1 of the pattern arrangement area 10X for the front body, and the upper end line U2 of the pattern arrangement area 10Y for the back body A cylindrical continuous body in which the pattern arrangement area 10X for the front body and the pattern arrangement area 10Y for the back body are respectively recognized as being connected in the virtual space, and a part of the upper end is closed in the virtual space. Recognized as

  Next, as shown in FIG. 4, in the pattern file reading procedure in STEP 30 and the pattern repeat (duplication) procedure in STEP 40, the entire pattern arrangement area 10X for the front body (entire surface) and the pattern arrangement area 10Y for the back body The read predetermined patterns 10A and 10B are duplicated and arranged without gaps on the entire surface (entire surface). Specifically, desired pattern data is read from an image file in which a large number of pattern data is stored, and the number of repeats is designated. Then, each area of the pattern arrangement area 10X for the front body and the pattern arrangement area 10Y for the back body is filled with the designated number of patterns 10A and 10B. Here, the data preparation procedure of STEP 10 and the mold piece arrangement procedure of STEP 20 are processed on the display screen, and the processing contents and instruction contents are displayed on the screen. Further, in the pattern file reading procedure in STEP 30 and the pattern repeat procedure in STEP 40, a predetermined screen such as a dialog screen for the operation and instruction is displayed on the screen, and the patterns for the closely located patterns 11 to 13 and patterns 21 to 24 are displayed. The grant status is displayed on the screen. On the other hand, the image itself in FIG. 4 shows internal processing and is not displayed on the screen. Note that FIG. 4 shows a pattern arrangement image when the number of repeats is set to 16, and the pattern data is adjusted so that 16 patterns (patterns of one constituent unit) can be accommodated horizontally on both the front and rear bodies. Are arranged side by side.

  Next, in the deformation processing procedure of STEP 50, first, in the deformation procedure constituting the deformation processing procedure, as shown in FIG. The inner meshes of the paper patterns 11 to 13 are deformed and rearranged so as to fill the gaps (gap portions D) formed between the outlines of the paper patterns 11 to 13 for use, and the paper patterns 11 to 13 adjacent to each other at the gap portions. Move the outlines of the two to approach each other. Similarly, the inner meshes of the patterns 21 to 24 are deformed and rearranged so as to fill the gaps (gap portions D) formed between the outlines of the patterns 21 to 24 for the back body, and adjacent to each other at the gaps. The outlines of the patterns 21 to 24 to be moved are moved closer to each other. On the other hand, in order to eliminate the missing pattern at the suture lines on the front and rear bodies, the gap S formed between the suture line on the left edge of the pattern 12 and the suture line on the right edge of the pattern 24 is filled up. The meshes inside the patterns 12 and 24 are deformed and rearranged, and the adjacent outlines of the patterns 12 and 24 are moved closer to each other. Similarly, the meshes inside the patterns 13 and 23 are deformed and rearranged so as to fill the gap S formed between the stitching line at the right edge of the pattern 13 and the stitching line at the right edge of the pattern 23. The adjacent outlines of the patterns 13 and 23 are moved so as to approach each other. Further, the inner side of the paper patterns 11, 21, and 22 is filled so as to fill a gap portion S formed between the suture line at the shoulder position of the upper edge of the paper pattern 11 and the suture line at the shoulder position of the upper edge of the paper patterns 21 and 22. The meshes are deformed and rearranged, and the adjacent outlines of the paper patterns 11, 21 and 22 are moved closer to each other. Here, the mesh deformation between the patterns 11-13 for the front body and the patterns 21-24 for the back body includes the right end line, the left end line, and the upper end line of the pattern arrangement area defined in the mold piece arrangement procedure. This is performed by moving the stitching lines of the pattern papers 11 to 13 and the pattern papers 21 to 24 so as to fill the gaps D and S between them. Further, the mesh is deformed by moving the vertex of the mesh. However, the adjacent suture line is not moved so that the finally joined suture line is linear, but is moved so that both suture lines come to the center position between the two suture lines, and the original shape It is moved while leaving. For example, as shown in FIG. 5, there are recesses 12x and 13x in the suture lines at the left and right ends of the patterns 12 and 13 in the front body, and correspondingly, the right and left ends of the patterns 24 and 23 in the back body. When the convex portions 24x and 23x having a shape corresponding to the suture line are present, the shape after the movement of the suture line is an uneven shape corresponding to the original uneven shape.

  Next, in the pattern imparting procedure constituting the deformation processing procedure, a series of patterns are applied to the entire area inside the outline of the plurality of mold pieces that are moved by deformation of the mesh to become an integrated area without gaps. Apply without gaps. Specifically, the pattern corresponding to the front body of the patterns 11 to 13 (after deformation) and the pattern 21 (after deformation) are brought into close contact with each other without any gap by mesh deformation. It assigns (appends) to the region corresponding to the rear body of ˜24. As a result, as shown in FIG. 6A, the pattern prepared in the pattern placement procedure remains in the original (original) pattern shape, and the area corresponding to the front body of the pattern 11 to 13 (after deformation) and (deformation) It is given to the area corresponding to the back body of the pattern papers 21 to 24. Next, in the associating procedure constituting the deformation processing procedure, the coordinates (for example, the pattern) of each component of the series of patterns given to the entire area inside the outlines of the patterns 11 to 13 and 21 to 24 are used. And the coordinates of the deformed mesh M (for example, the coordinates after the vertex of the mesh M is moved) are associated with each other. Next, in the reverse deformation procedure constituting the deformation processing procedure, each vertex of the deformed mesh M is returned to the coordinate position before the movement (original), and the outlines of the patterns 11 to 13 and 21 to 24 are moved. Return to the previous position. As a result, the same gaps (gap part D and the like) that existed before the movement are formed again between the outlines of the patterns 11 to 13 and 21 to 24. At this time, each structural element of the pattern associated with each of the deformed meshes M is moved and copied to the coordinate position of the corresponding mesh M before the movement. As described above, the pattern information is added to the front and rear body equivalent areas after being deformed by the deformation procedure, and the pattern is copied to the front and rear body equivalent areas before the deformation by the reverse deformation procedure. The transformation of is completed. Thereby, as shown in FIG.6 (b), the pattern part which should be missing in the clearance gap part of the outline of pattern papers 11-13, 21-24 is an inner area | region of the outline line of pattern papers 11-13, 21-24. The pattern is completely continuous even in the gaps between the outlines of the patterns 11 to 13 and 21 to 24, and is not lost. However, the pattern copied inward at the gaps between the outlines of the patterns 11 to 13 and 21 to 24 is slightly distorted from the original shape due to compression by the reverse deformation procedure. Note that a polygon drawing technique (texture mapping) mainly used for three-dimensional display can be used for copying the pattern in the reverse deformation procedure.

  As described above, the meshes are deformed by moving only one of them to approach the other without moving both of the opposing outlines of the patterns 11 to 13 and 21 to 24, and then deforming the mesh. By returning to the previous position, the pattern can be added to the region corresponding to both the front and rear bodies without missing the pattern, but in this case, the distortion of the pattern increases. Therefore, from the point of minimizing the distortion of the handle, as described above, the opposing outlines of the paper patterns 11 to 13 and 21 to 24 are moved so as to approach each other, and then returned to the position before the deformation. By doing so, it is preferable to add to the region corresponding to both the front and rear bodies without missing the pattern.

  Next, the deformation processing procedure of STEP 50 will be described in more detail with reference to FIG. 2B, FIG. 7 and FIG. As shown in FIG. 2B, the deformation processing procedure of STEP 50 includes a joining line joining procedure of STEP 51, a side elongation analysis procedure of STEP 52, and a spring calculation procedure of STEP 53, and these procedures are performed a predetermined number of times ( Repeat 10 to 100 times). Specifically, first, in the joining procedure, as shown in FIG. 7A, joining lines (stitching lines and stitching sides) of the respective outlines of the adjacent front body pattern 10 and rear body pattern 20 ) The mesh vertices (vertices connected by a broken line in the figure) at corresponding positions (opposing positions or the same vertical positions) across the central gap between the pattern paper 10 and the pattern paper 20 are respectively connected to each other. Move by a certain percentage to approach. For example, first, as shown in FIG. 7B, the moving amount of each pair of meshes is set to 10% of the distance between vertices of the paired meshes, and the paired meshes are moved. In FIG. 7B, the alternate long and two short dashes line indicates the position before the suture side (and each mesh) is moved (position of FIG. 7A), and the solid line indicates the position after the suture side is moved by 10%. Then, the vertices of each mesh move by 10% with respect to the vertices of the counterpart mesh, and the distance is reduced by 20% in total. Note that the calculation of the distance between the vertices is performed in consideration of the fact that the front and back bodies are spatially connected. Thereafter, in the next vertex movement, for example, the movement distance is gradually increased by a predetermined ratio of 12% and 14%, and finally, as shown in FIG. Are completely overlapped (joined / connected). At this time, the moving distances of the vertices of the meshes of the patterns 10 and 20 are 50% (100% in total).

  On the other hand, each time the vertex of the mesh between the corresponding stitched sides in the joining line joining procedure is moved by a predetermined rate, the side elongation rate analysis procedure and the spring calculation procedure are executed, and the mesh stretched by the movement of the mesh vertex The vertices of the sides connected to both ends of the side are moved so that the sides extending from the vertices of the mesh are restored to the state before extension, and the distortion of the sides is not limited to the vicinity of the boundary line of the patterns 10 and 20, but also the patterns 10 and 20 Distributed throughout. Specifically, as shown in FIG. 8A, a part of the side (the side of the mesh closest to the boundary line of the paper patterns 10 and 20) is extended by the joining line joining procedure of STEP 51 (FIG. 8). Middle arrow direction). Therefore, in STEP 52, the elongation rate of some of the sides is analyzed and calculated, and in accordance with the elongation rate, in STEP 53, the stretched sides are acted on the vertices at both ends of the side to return to the original state ( The direction of the arrow in the figure). Then, the extension of the side does not return to the original state, and another side adjacent to the side is extended. Therefore, it further acts on the vertices at both ends of those sides so that the other extended side returns to the original state (in the direction of the arrow in the figure). In this spring calculation procedure, the mesh in the patterns 10 and 20 is regarded as a spring network, and the physical model (dynamic model) is simulated, so that the deformation (distortion) of the mesh is part of the patterns 10 and 20 (boundary line). Dispersed throughout rather than near. That is, replace each mesh edge with a virtual spring, analyze the force applied to each vertex of the mesh from the virtual spring (attractive force, repulsive force, etc. according to the spring coefficient), and calculate the movement of each mesh vertex To do. As the spring calculation process, for example, the same technical idea as that of the spring / mass system model can be used. In this way, by repeating the joining line joining procedure in STEP 51 and the spring calculation process in STEP 53, the entire mold pieces 10 and 20 approach the target rectangle shown in FIG. In addition to the above spring calculation procedure, any physical model (dynamic model) or shape deformation model can be used as long as the mesh distortion can be distributed over the entire pattern.

  When the deformation processing procedure of STEP 50 is completed, in the pattern alignment procedure of STEP 60, the completed sample generation / display procedure of STEP 70, and the confirmation procedure of STEP 80, the position of the pattern is confirmed while checking the completed drawing of the clothes on the display screen. adjust. Specifically, using the apparel design system and the like used in the data preparation procedure, accurate three-dimensional data is created for clothes to be subjected to pattern matching (pattern assignment) by the pattern matching program of this embodiment. If the pattern is displayed, two-dimensional data about the pattern given the pattern in the above-described steps is displayed on the screen, and three-dimensional data (finished image) of the clothes created using the pattern is displayed on the screen. Then, the position of the pattern on the pattern is adjusted while checking the completed drawing of the clothes so that the pattern comes to the optimum position. For example, when a large pattern such as a flower pattern is given in addition to the pattern pattern shown in the present embodiment, the large pattern moves so as to come to the chest. If it is necessary to correct the pattern in STEP 80, the process returns to STEP 40, STEP 50, and STEP 60, and the necessary correction is performed. Finally, when the pattern with no pattern correction is completed in STEP80, the pattern image with the pattern (the image after reverse deformation) is generated and stored in the reverse deformation image generation / storage procedure of STEP90. Then, the entire process is terminated.

  The pattern matching program according to the present invention can be applied to any garment having a pattern in addition to the clothes of the above-described embodiment, and further formed into a three-dimensional shape using a plurality of mold pieces in addition to the garment. It can be applied to any continuous sheet body (for example, hats, chair covers, shoes, bags, etc.). That is, the continuous sheet body to which the pattern matching program according to the present invention is applied is typically a clothing such as clothes, but a planar (two-dimensional) mold having a predetermined shape having a predetermined outline. A plurality of (pattern paper) is used, and a plurality of fabrics (fabrics) cut (cut) into a shape corresponding to the outer shape line of the die piece are joined (sewn) at a position corresponding to the outer shape line, and the die piece is supported. As long as it is formed into a three-dimensional shape, it can be embodied as an arbitrary one. Moreover, the continuous sheet object to which the pattern matching system of the present invention is applied corresponds to only one of the front body and the back body, in addition to the front body and the back body as in the clothes of the above embodiment. It can consist of parts. Further, the continuous sheet body may use a pattern other than the body such as a sleeve and a collar, and the present invention can be similarly applied to such a case.
