FIG. 2 is a diagram showing reference paper pattern data stored in the paper pattern data creating apparatus according to the first embodiment of the present invention. FIG. 2 shows two patterns out of a plurality of patterns that form the pattern data. For example, it is assumed that the pattern M ₁ shown in FIG. 2 is "40 size" and the pattern M ₂ is "60 size". The pattern data constituting these patterns M ₁ and M ₂ is stored in advance in the pattern data storage unit 14a, and is a reference pattern data for creating pattern data of different sizes (hereinafter, also referred to as reference pattern data).

FIG. 3 is a flowchart showing a pattern creating process performed by the pattern data creating apparatus according to the first embodiment of the present invention. When the input unit 11 receives the input of the pattern data creation instruction, the data selection unit 131 selects the reference pattern data of a different size (step S101). Here, when the data selection unit 131 selects the reference pattern data from the size of the size, for example, the minimum size and the maximum size of the size of the reference pattern data stored in the pattern data storage unit 14a are selected. Extract and compare with the size of the size created this time (here, called the specified size). At this time, the data selection unit 131 compares the designated size with the minimum size and the maximum size, and if the designated size is larger than the minimum size and smaller than the maximum size, the reference pattern paper having a size smaller than the designated size is used. The maximum size standard paper pattern data of the data and the minimum size standard paper pattern data of the standard paper data of a size larger than the specified size are selected. If the designated size is smaller than the minimum size, the data selection unit 131 selects the reference pattern data having the smallest size with respect to the designated size and the reference pattern data having the second smallest size. If the designated size is larger than the maximum size, the data selection unit 131 selects the standard paper pattern data having the largest size with respect to the designated size and the standard paper pattern data having the second largest size.

After selecting the reference pattern data, the weight calculation unit 132 calculates the weight of each reference pattern data (step S102). The size of the specified size is S, the size of one selected size is S ₁ , the size of the other size is S ₂ , the weight of one of the selected sizes is w ₁ , and the weight of the other size is w. When _2, the weights w _1, w _2, based on the relationship of the size of the specified size, the size of the reference paper data, the following equation (1) is calculated by (2).

After calculating the weight, the correspondence relationship determination unit 133 determines the correspondence relationship between the reference pattern data (step S103). The correspondence relationship determination unit 133 determines the correspondence relationship between the vertices and contour lines of the pattern.

After that, the vertex position determination unit 134 determines the vertex position of the pattern of the size to be created (designated size) (step S104). The apex position determining unit 134 determines the apex position of the pattern of the specified size corresponding to the apex of the pattern of the reference pattern data by using the reference pattern data and the weight.

The contour generation unit 135 generates a contour line connecting the vertices determined by the vertex position determination unit 134 by using the reference pattern data and the weight.

FIG. 4 is a diagram for explaining an example of the pattern data created by the pattern data creating apparatus according to the first embodiment of the present invention, from the reference pattern data of "40 size" and "60 size" to "50 size". It is a figure explaining the example of creating the pattern data of.

The weight calculation unit 132 calculates the weight when creating the "50 size", where the weight of the "40 size" is w ₁ and the weight of the "60 size" is w ₂ . The above equations (1) and (2) are used to calculate the weight. In this case, the weights w ₁ and w ₂ are 0.5, respectively.

After that, the vertex position determination unit 134 determines the vertex position of the “50 size” pattern using the calculated weights w ₁ and w ₂ and the correspondence relationship determined by the correspondence relationship determination unit 133. For example, a vertex P ₁₀₀ of paper M _1, the paper M ₂ vertices P ₁₀₁ Prefecture, to determine the vertex position of the paper (paper D ₁ of the post-creation) of "50 size" in the vertex P _102. Specifically, the coordinates of the apex P ₁₀₀ of the pattern M ₁ are (x ₁₀₀ , y ₁₀₀ ), the coordinates of the apex P ₁₀₁ of the pattern M ₂ are (x ₁₀₁ , y ₁₀₁ ), and the coordinates of the apex P ₁₀₂ of the size to be created. If is (x ₁₀₂ , y ₁₀₂ ), x ₁₀₂ and y ₁₀₂ are calculated by the following equation.
x ₁₀₂ = w ₁ x x ₁₀₀ + w ₂ x x ₁₀₁
y ₁₀₂ = w ₁ x y ₁₀₀ + w ₂ x y ₁₀₁

Contour generation unit 135 generates a contour by connecting the apexes determined, to create a paper pattern D ₁ of the "50 size". At this time, the contour generation unit 135 merges the shapes of the reference pattern M ₁ and the pattern M ₂ to generate a contour line.

FIG. 5 is a diagram illustrating another example of the pattern data created by the pattern data creating apparatus according to the first embodiment of the present invention, from the reference pattern data of "40 size" and "60 size" to "70". It is a figure explaining the example of creating the pattern data of "size".

Weight calculator 312, as in the case of "50 size", the weight w ₁ of "40 size", calculates the weight w ₂ of "60 size". The above equations (1) and (2) are used to calculate the weight. In this case, the weight w ₁ is −0.5 and w ₂ is 1.5.

After that, the vertex position determination unit 134 determines the vertex position of the “70 size” pattern using the calculated weights w ₁ and w ₂ and the correspondence relationship determined by the correspondence relationship determination unit 133. For example, a vertex P ₁₀₀ of paper M _1, from the apex P ₁₀₁ Metropolitan of paper M _2, to determine the vertex position of the paper (paper D ₂ after creation) of "70 size" to the vertex P _103.

The contour generation unit 135 generates a contour by connecting the determined vertices to each other, and creates a “70 size” pattern D ₂ .

FIG. 6 is a diagram illustrating a contour forming process performed by the pattern data creating apparatus according to the first embodiment of the present invention. For example, when drawing an equally dividing line (w ₁ = 0.5, w ₂ = 0.5) between the curve L ₂₀₀ of one reference pattern and the curve L ₂₀₁ of the other reference pattern, first, The curve L ₂₀₀ is divided into n equal parts (n = 8 in FIG. 6) with the points P ₂₀₁ and P ₂₀₂ as end points, and the curve L ₂₀₁ is divided into n equal parts with the points P ₂₁₁ and P ₂₁₂ as end points. After that, the corresponding points are connected in order, and the position for equally dividing the connected line segment is determined. For example, P ₂₂₁ is attached at a position that equally divides the line segment connecting P _{201 of the} curve L ₂₀₀ and P _{211 of the} curve L ₂₀₁ , and connects P _{202 of the} curve L ₂₀₀ and P _{212 of the} curve L _201. Add P ₂₂₂ to the position that divides the line segment evenly. Similarly, a point is attached at a position where the line segment connecting the points of the corresponding curve L ₂₀₀ and the curve L ₂₀₁ is equally divided, and a curve L ₂₀₂ connecting the points smoothly is generated. This curve L ₂₀₂ is a contour line according to the size of the pattern to be created. In this way, a pattern of the size to be created is generated by generating a contour line connecting each vertex and matching the corresponding vertices with each other.
In FIG. 6, the case where the two curves are equally divided (w ₁ = 0.5, w ₂ = 0.5) has been described as an example, but other than the equal division, the two curves are proportionally divided into w ₁ : w ₂ . A line is created.

In the first embodiment described above, the pattern data of a designated size is created by using the plurality of reference pattern data. In the past, it was only possible to deform one reference pattern with a similar shape based on the indicated value, or it was necessary to enter the indicated value in detail to deform the reference pattern. In No. 1, for example, when the curvature of the contour line differs between sizes, it is possible to create pattern data corresponding to the change in the curvature. According to the first embodiment, it is possible to easily create the pattern data suitable for the shape of the pattern creation target.

(Modification 1 of Embodiment 1)
Next, a modification 1 of the first embodiment of the present invention will be described. The pattern data creating device according to the first modification of the first embodiment has the same configuration as the pattern data creating device 1 according to the first embodiment described above. In the first modification, a case where the size of a part of the paper pattern created by the above processing is changed will be described.

FIG. 7 is a diagram illustrating a pattern data creation process performed by the pattern data creation device according to the first modification of the first embodiment of the present invention. The pattern shown in FIG. 7 describes, for example, an example in which a part of the pattern D _M is deformed when the pattern D _M is created from the reference patterns D _S and D _L by the above-mentioned processing. The paper pattern D _M is larger than the standard paper pattern D _{S and} smaller than the paper pattern D _L as the size of the paper pattern. In this modification 1, the reference pattern D _S is S size, the reference pattern D _L is L size, and the pattern D _M is M size. The reference patterns D _S , D _L , and the pattern D _M are provided with pocket lines corresponding to the pocket arrangement positions. Specifically, the standard paper pattern D _S is given a pocket line D _SP , the standard paper pattern D _L is given a pocket line D _LP , and the paper pattern D _M is given a pocket line D _MP . Hereinafter, some sizes of this pattern D _M will be changed to the size of the standard pattern D _S or the standard pattern D _L.

8A to 8G are diagrams for explaining the pattern data creation process performed by the pattern data creation device according to the first modification of the first embodiment of the present invention, and are views for explaining the pattern data transformation process.

First, the input unit 11 receives instruction information size Changes for paper D _M. Here, as shown in FIG. 8A, the size of the pocket line D _MP is changed to S size (pocket line D _SP ), the bust line D _M1 and the lower center line D _M2 are changed to L size, and the hem line D _M3 To S size.
At this time, if a plurality of lines to be resized form a closed ring, these lines must all have the same size to be resized. For example, in FIG. 8A, the plurality of lines forming the pocket form an annular shape, but all the lines are designated as S size, which is acceptable. On the other hand, aside line D _M4 is bust line D _M1 An annular, lower center line D _M2, the hem line D _M3 and Wakisen D _M4, hem line D _M3 is specified in S size, bust line D _M1 is L Since the size is specified, the size specification of S size or L size is not allowed in order to maintain the ring shape of the changed part.

The contour generation unit 135 groups continuous lines among the lines designated as the changed parts. The case shown in FIG. 8B, the contour of the pocket line D _MP are grouped as the region R _1, bust line D _M1, contour line indicating the lower center line D _M2 and Susosen D _M3 are grouped as a region R ₂ To.

Then, in each grouped area, one fixed point is indicated. In the first modification, a plurality of free points are displayed on the contour line at the time of grouping, and the user instructs the fixed points via the input unit 11. A free point is a point where the position moves due to a change in size, and a fixed point is a point where the position does not move even if the size is changed. In Figure 8C, an example in which free point P ₄₁ is designated as a fixed point in the region R ₁ free point P ₄₁ to P ₄₄ that is set in the (pocket line D _MP). Further, an example in which free point P ₅₁ is designated as a fixed point of the free point P ₅₁ to P ₅₄ are set in the region R _2. Hereinafter, the free point P ₄₁ and the free point P ₅₁ may be referred to as a fixed point P ₄₁ and a fixed point P ₅₁ .

After determining the fixed point, the contour generation unit 135 changes the size of the changed portion with the fixed point as a fulcrum (see FIG. 8D). Specifically, the size of the pocket line D _MP is changed to the S size with the fixed point P ₄₁ as the fulcrum to make the pocket line D _SP , and the bust line D _M1 and the lower center line D _{M 2} are used as the fulcrum of the fixed point P _51. Change to L size (bust line D _L1 and lower center line D _L2 ), and change the hem line D _M3 to S size (hem line D _S1 ) with the changed free point P ₅₃ as a fulcrum.

When the size of the changed part is changed, there may be a part where the connection of the contour lines is broken. In FIG. 8C, the connection between the free point P ₅₂ and armhole after the change (armhole Q _M shown in FIG. 8E), and, thus cutting the connection between the free point P ₅₄ and the free point P ₅₂ after the change .. Therefore, the contour generation unit 135 interpolates so that the contour lines are connected by merging the lines. The specific processing of line merging will be described later.

A free point P ₅₂ after the change, merging the armhole Q _M (see FIG. 8E) includes a armhole Q _M of paper D _M, the armhole Q _L of paper D _L corresponding to the bust line D _L1 Merge. By merging the armhole Q _M and armhole Q _L, the armhole Q _M 'after the change is obtained (see FIG. 8E).

In addition, the merge of the side lines connecting the free points P ₅₂ and the free points P ₅₄ after the change is performed by merging the side lines D _L4 of the pattern D _L corresponding to the bust line D _L1 and the pattern D _{L 4} corresponding to the hem line D _{S 1.} Merge with the side line D _{S4 of S.} By merging the side line D _L4 and Wakisen D _S4, the side lines D _M4 'after the change is obtained (see FIG. 8F).

The merging process described above, paper D paper D _M a partial modification of the size of _M 'is obtained (see FIG. 8G).

Here, the merging of lines will be described with reference to FIGS. 9 to 12. FIG. 9 is a diagram (No. 1) for explaining the line merging process in the pattern data performed by the pattern data creating apparatus according to the first modification of the first embodiment of the present invention. Here, as shown in FIG. 9, the curve L ₆₀ having P ₆₁ as one end point and the curve L ₇₀ having P ₇₁ as one end point are merged, and P ₆₁ and P ₇₁ are used as both end points. curve an example of generating a (dashed L ₈₀ shown in FIG. 9) will be described such.

FIG. 10 is a diagram (No. 2) for explaining the line merging process in the pattern data performed by the pattern data creating apparatus according to the first modification of the first embodiment of the present invention. The contour generation unit 135 divides the curves L ₆₀ and L ₇₀ into equal numbers, connects the end point P ₆₁ with the end point P ₇₁ of the curve L _{70 and} the end point P ₇₂ on the opposite side, and ends the curve L ₆₀ . The end point P ₆₂ on the opposite side of P ₆₁ and the end point P ₇₁ are connected.
