Description

  The present invention relates to a virtual paper pattern creation device, a virtual paper pattern creation method, a virtual paper pattern creation program, and a computer-readable recording medium on which a virtual paper pattern creation program is recorded. .

  Conventionally, a pattern making apparatus having a grading function, which is one of the methods for creating a pattern for clothes that matches the body shape of a human body, is known (for example, see Patent Document 1). In grading, a paper pattern corresponding to the body shape is created by enlarging or reducing an existing paper pattern.

  Table 1 below compares an example of the size of ready-made clothing worn by adult girls with the actual measured size of the subject. As shown in Table 1 below, the size of ready-made garments stipulated as 9AR in the JIS standard is 158cm in height (T), 83cm in bust (B), 64cm in waist (W), and hip (H). Is 91 cm. The size of ready-made garments defined by the JIS standard as 19YR is 158 cm in height (T), 100 cm in bust (B), 76 cm in waist (W), and 97 cm in hip (H). If the body size of the subject (Tester) is 158 cm tall, bust 100 cm, waist 80 cm, and hip 97 cm with respect to the size of these ready-made clothing, the size of the clothes worn by the subject is classified as 19YR. . Therefore, when the subject wears 9AR clothes, the pattern of the 9AR clothes needs to be graded.

  However, the body shape changes depending on the age and environment, and is different for each person. Therefore, when grading is performed by the conventional pattern making apparatus, the existing pattern is simply enlarged or reduced, so the clothes are not always in accordance with the individual body shape.

  For example, in the example of Table 1, the difference (diff.) Between the subject's bust size and the 9AR bust size is 17 cm, and the hip size difference is 6 cm. Therefore, when grading according to the subject's bust size using 9AR clothing pattern as a master pattern, the hip size does not fit because the entire pattern is enlarged by 17 cm. Similarly, when grading according to the subject's hip size using a 9AR clothing pattern as the master pattern, the overall size is enlarged by 6 cm, so the bust size does not match.

  As shown in FIG. 5A, when a three-dimensional image of a human body is developed with a development line connecting each feature point, it is divided into a plurality of regions (seven regions in the present embodiment). And as shown in FIG.5 (b), the feature point and the development line are shared in the some area | region. 5B represents the feature points in FIGS. 4A and 4B, and the square points copied and moved the feature points in FIGS. 4A and 4B. Represents the point. For example, the point NP, the point NP ′, and the point NP ″ are the same feature points, and the point D2, the point D2 ′, and the point D2 ″ are the same feature points.

  Note that the developed image creation unit 102 in this embodiment creates a two-dimensional developed image of the right half and a two-dimensional developed image of the left half. The two-dimensional unfolded image of the right half and the two-dimensional unfolded image of the left half may be created at the same time. Alternatively, after the two-dimensional unfolded image of the right half is created, the two-dimensional unfolded image of the left half is created. In addition, after creating a two-dimensional developed image of the left half, a two-dimensional developed image of the right half may be created.

  Returning to FIG. 3, in step S <b> 3, the average developed image creation unit 103 is an image obtained by horizontally inverting the two-dimensional developed image of the right half of the human body and the two-dimensional developed image of the left half created by the developed image creating unit 102.

  FIG. 6 is a diagram in which a two-dimensional developed image of the right half of the human body and an image obtained by horizontally inverting the two-dimensional developed image of the left half are superimposed. In FIG. 6, the two-dimensional developed image RG of the right half of the human body is indicated by a solid line, and the image LG obtained by horizontally inverting the two-dimensional developed image of the left half of the human body is indicated by a broken line. Although there are individual differences, the right half and the left half of the human body do not necessarily match. As shown in FIG. 6, the two-dimensional developed image RG of the right half of the human body and the two-dimensional developed image of the left half are reversed left and right. When the image LG is overlaid, there is a possibility of deviation.

  Therefore, the average developed image creation unit 103 obtains and obtains the midpoint between the feature point in the two-dimensional developed image RG of the right half of the human body and the feature point in the image LG obtained by horizontally inverting the two-dimensional developed image of the left half. By connecting the midpoints, an average developed image is created by averaging the left and right two-dimensional developed images.

Since the average developed image HG is a developed three-dimensional image of the human body, if a pattern is created from the average developed image HG, the clothes are in close contact with the human body. For this reason, a pattern for a comfortable garment is created by enlarging the average developed image HG and providing a clearance. The clearance is provided by enlarging the straight lines K1 to K12 shown in FIG. 8 with a predetermined size. In the present embodiment, as shown in FIG. 9, a predetermined position in the average developed image HG is enlarged by a predetermined interval, and as a whole, it is enlarged by 4 cm in the horizontal direction.
