Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for creating part data of clothing using a computer, and to a method of manufacturing clothing using the method for creating part data.

[0002]

2. Description of the Related Art Conventionally, in the planning of clothing in the apparel industry, first, a basic clothing silhouette is determined.
Next, a method has been adopted in which various design variations are created by applying details such as various sleeves, collars, pockets, buttons, etc. to the determined silhouette to develop the design.

By the way, since the work of developing a design by changing the details of the determined silhouette can be reduced to a relatively mechanical work, an inexperienced patterner (pattern creator) However, it can be implemented and can be executed in a relatively short time. On the other hand, the task of determining the basic clothing silhouette described above is a difficult task that requires advanced part creation techniques and experience, and takes several days even for a veteran patterner. Also, determining the silhouette is a very important task, because the quality of the silhouette has a great effect on the sales of clothes.

[0004] Basic silhouettes are usually created by inflating ideas, such as giving a little room near the waist or changing the shoulder line, referring to the basic silhouettes created in the past. This is done by directly applying a toilet (prototype fabric corresponding to each part of the garment) to the table (a pin-punchable mannequin used to make the garment), cutting off excess parts, and assembling with pins. This operation takes a long time, even for a veteran patterner, through repeated trial and error. Also, the thought of the pattern is usually based on the body (human body), and as described above, it is imagined that the waist has room or the shoulder line is changed, but the base is based on the standard figure For example, even if the waist is allowed to have a clearance of about 70 cm, the work becomes difficult because the toilet drops due to gravity. Also, even if it is said that the waist has room for about 70 cm, it is important to know which part should be enlarged and how much should be given, for example, the abdomen, flanks, back, etc. There is a problem that various knowledges are required and it is difficult to determine even a veteran patterner.

[0005] In recent years, with the advance of computer technology, apparel CAD for making a pattern has come to be used also in the field of making a pattern for a garment (a piece of paper simulating the planar shape of a part of the garment). Also, recently, pattern data (parts data.
Regardless of whether a pattern is actually created or not, it may be referred to as pattern data. ), A technique of simulating the completed state of clothes by virtually sewing parts virtually created on the basis of a computer and attaching the parts virtually to a computer mannequin. For example, the method of Japanese Patent No. 1984093 by the present applicant, the method of Japanese Patent Application Laid-Open No. H10-124528,
No. 31979. However, in these methods, even though the finished state of the clothes can be confirmed from the pattern data without manufacturing the sample clothes,
As described above, there has been a problem that it is not easy to change the silhouette of the clothes and obtain a pattern or pattern data that reproduces the silhouette.

[0006] Further, as described above, it is difficult to obtain part data that reproduces a silhouette as an image, and as a result, there is a problem that it is difficult to manufacture clothes having a silhouette as an image.

[0007]

And a function of creating deformed human body outline shape data deformed according to body shape data such as bust and waist input using the mouse or the mouse (103). In the present embodiment, a rule for deforming the approximate human body shape, that is, a numerical value or a function indicating how much each feature point constituting the general human body shape should be moved is stored in advance in the human approximate shape data storage unit (114). ), The input body type data is applied to the rule, and the feature points are moved to create deformed human body outline shape data. The transformation rule can be obtained by statistically processing a large number of human body data. Deformed human body outline shape data creation means (1
08) is described in Japanese Patent Application No. 10-345 filed by the present applicant.
No. 579, it is described in detail.

Modified clothing shape data creating means (109)
The clothing shape data, the human body outline shape data before deformation, and the deformed human body outline shape data creation means (108)
There is a function of creating clothing shape data after the deformation based on the deformed human outline shape created by the above. The clothing shape data after the deformation includes the human shape outline data before the deformation and the human shape outline data after the deformation (deformed human body shape data).
Approximately calculated and created based on the difference between The deformed garment shape data creating means (109) is described in detail in Japanese Patent Application No. 10-345579 by the present applicant. In the present embodiment, since the human body shape data is not displayed on the data display means (111) described later, only the clothing shape data is deformed. However, when the human body shape data is also displayed on the display (104), the same applies. Needless to say, it is desirable that the human body shape data is also deformed.

Modified clothing parts data creation means (11)
0) is based on the clothing shape data before deformation, the clothing shape data after deformation (deformed clothing shape data), and the clothing part data corresponding to the clothing before deformation. There is a function to create clothing parts data corresponding to clothing shape data. The means for creating deformed clothing parts data is different in each of the three embodiments described below, and will be described in detail later.

The data display means (111) displays clothing shape data, deformed clothing shape data, clothing part data, deformed clothing part data, human body outline shape data, deformed human body outline shape data (104). Has a function of displaying using computer graphics technology. With the data display means (111), the user can check the shape of the clothing before and after the deformation, check the part data of the clothing before and after the deformation, and check the outline shape data of the human body before and after the deformation. In this way, by sequentially checking the shape data, the difference between the shape data envisioned by the user in the mind and the shape data calculated by the computer is recognized, and further the shape data is instructed based on the difference. Therefore, it is possible to create desired shape data.

The data printing means (112) has a function of printing clothing shape data before and after deformation and clothing part data before and after deformation. The printed clothing part data can be used as a pattern and can be used for actual clothing production. Clothing shape data created by computer graphics can be used as reference data for planning and evaluating clothes.

The data output means (113) has a function of outputting clothing shape data before and after deformation and clothing part data before and after deformation online or offline. CA using an automatic cutting machine (a device that cuts out clothing parts directly from the fabric without creating a pattern) or an automatic sewing device
When clothing is manufactured by M (Computer Aided Manufacturing) or the like, clothing can be manufactured by inputting clothing part data output by the data output means (113) to those devices. Also, by inputting clothing shape data to an optical molding device or the like by the data output device (113), a three-dimensional model or miniature of clothing can be created, and these can be used for clothing planning and the like. The data output means (113) can be realized by a floppy disk drive or an optical disk drive for offline output, and can be realized by a data communication device and a network cable for online output.

Next, the outline of the operation of this embodiment will be described with reference to the flowchart of FIG.

In step 701, the keyboard (1
02) or the mouse (103), input of clothing part data of clothing to be processed is designated. The input is specified by inputting the design code of the clothing. When the design code of the garment is input, the garment part data of the garment is extracted from the garment part data storage means (115). In this embodiment, the clothing part data is registered in advance in the clothing part data storage means (115). However, even if the pattern CAD data as the clothing part data is input online or offline each time, Good.

In step 702, step 701
Based on the clothing part data input in step (1), clothing shape data creating means (107) creates clothing shape data and inputs it to the memory of the personal computer (101). In this embodiment, when the clothing shape data is created, it is displayed by the data display means (111), so that the shape of the clothing can be confirmed. In addition,
If the clothing shape data has already been registered in the clothing shape data storage means, this step can be omitted, and the registered clothing shape data can be taken out and substituted. When the registered clothing shape data is used, the time for creating the clothing shape data can be omitted, and the calculation time can be reduced.

At step 703, the keyboard (1
02) and a mouse (103) to input body shape data. Examples of the body type data include values representing the dimensions of each part of the human body, such as bust, waist, hip, shoulder width, and height, and data representing the posture of the human body, such as the degree of dropping of the shoulder line and the degree of stoop. In addition, a value that specifies the position of a characteristic point of the human body, such as the position of the nipple or the position of the shoulder point, may be input.

At step 704, the deformed human outline shape forming means (108) generates human outline shape data corresponding to the body shape data input at step 703.

In step 705, the shape of the deformed garment is determined by using the human shape data before deformation stored in the human shape data storage unit (114) and the human shape data after deformation created in step 704. The clothing shape data input in step 702 is transformed by the data producing means (109) to produce transformed clothing shape data. FIG. 8 shows the garment shape data before deformation (A) and the deformed garment shape data (B) when the value of the waist is increased so that the waist has room. In this embodiment, the clothing shape data before and after the deformation is displayed on the display (102) by the data display means (111). Thereby, the user can confirm the quality of the inputted body type data by comparing the silhouette of the clothing imaged by the user with the silhouette of the clothing shape displayed on the display. If the result is different from that of the user's own image, the process returns to step 703 and the body shape data can be input again. By repeating this work, you can get the silhouette of the clothes as you imagine. Since the deformation of the clothing is performed by manipulating the body shape data, the deformation intended by the user, the patterner, such as giving the waist more room or raising the shoulder line a little, can be easily performed.
In this way, it is possible to easily create the clothing shape data reflecting the clothing silhouette according to the image of the user.

In step 706, step 705
The transformed clothing part data (pattern data) corresponding to the transformed clothing shape data created in step (1) is created by the transformed clothing part data creating means (110). This makes it possible to easily obtain clothing part data (pattern data) that realizes the silhouette of the clothing imagined by the user.

In step 707, the transformed clothing part data created in step 706 is printed out from the printer (105) by the data printing means (112).
Thus, a clothing pattern corresponding to the silhouette of the clothing determined in step 705 can be obtained. If a pattern is not necessary due to the introduction of a CAM or the like in the process of manufacturing the garment, the data output means (113) is used instead of printing.
Thus, deformed clothing parts data may be output.

As described above, the user deforms the clothing shape data by giving virtual body shape data, confirms it on the display, and further shows the body shape data based on the display result of the display to display the same virtual shape data. By repeating the basic sewing, the optimal clothing silhouette can be determined, and clothing part data that realizes the determined clothing silhouette can be easily obtained. When clothing is manufactured based on the clothing part data obtained in this manner, clothing as imagined by the user can be quickly and reliably manufactured as shown in FIG. 8B. At the same time, it is possible to obtain clothes according to the image of the user. [Embodiment 1] Next, a modified clothing parts data creating means (110) according to a first embodiment of the present invention will be described.

In this embodiment, mesh data after deformation is approximately created using mesh data before deformation, clothing shape data before deformation, and clothing shape data after deformation. Pattern CAD based on the mesh data of
The data is transformed to create transformed clothing shape data.

A method for creating deformed clothing shape data will be described with reference to FIG.

In FIG. 9, A represents clothing shape data before deformation, A ′ represents clothing shape data after deformation, and B represents mesh data before deformation. P and Q represent nodes of the clothing shape data before deformation, and P ′ and Q ′ represent nodes corresponding to P and Q of the clothing shape data after deformation. p and q are P,
Represents a node on the mesh data corresponding to Q. At this time, from the relationship where P has moved to P ′ and Q has moved to Q ′, p ′ and q ′ have been moved p and q to correspond to this movement relationship.
Is calculated. Thus, by moving all the nodes of the mesh data, the deformed clothing parts data (B ′) can be obtained.

The method of creating the deformed clothing shape data of the first embodiment is described in Japanese Patent Application No.
It is described in detail in the specification of Japanese Patent No. 102907. [Embodiment 2] Next, a modified clothing parts data creating means (110) in a second embodiment of the present invention will be described.

In this embodiment, the deformed clothing part data is created by flattening the three-dimensional part data constituting the deformed clothing shape data, which is the deformed clothing shape data.

FIG. 1 shows a method of creating deformed clothing shape data.
Explanation will be made using 0.

In FIG. 10, A is one of the three-dimensional part data constituting the deformed clothing shape data, and B is one of the three-dimensional part data constituting the deformed clothing shape data. Here, the three-dimensional part data is flattened using the finite element method so that the strain energy is minimized. For example, for a triangular element constituting three-dimensional part data, a bending recovery force is defined according to an angle formed by two triangular elements sharing one side (hereinafter, referred to as an inter-element angle). The smaller the angle, the larger the bending recovery force, and the larger the angle, that is, closer to 180 degrees, the smaller the bending recovery force. In this way, the bending recovery force is defined, and the three-dimensional part data is deformed, that is, developed in a plane according to the bending recovery force. The calculation for the plane development is repeated until all the angles between the elements are closer to 180 degrees than the preset threshold value.
Then, two-dimensional part data obtained by developing the three-dimensional part data on a plane can be created. When the three-dimensional part is developed in a plane as described above, the shape of each element constituting the three-dimensional part data is deformed in the process of being converted into two-dimensional data. This deformation is calculated as strain energy, and the sum of strain energy of each element is calculated. The shape of each element is modified so that the sum of the distortion energies is minimized. In the actual calculation,
Since minimization is difficult, the calculation may be repeated until the sum of the distortion energies becomes equal to or less than a certain threshold value, and the calculation may be terminated when the sum becomes equal to or less than the threshold value. Thus, two-dimensional part data corresponding to the three-dimensional part data, that is, deformed clothing part data can be obtained. Similarly, deformed clothing part data can be obtained by flattening all three-dimensional part data constituting the deformed clothing shape data.

The method for defining the bending recovery force is as follows.
For example, it is described in "Virtual Clothing PARTY Numerical Calculation Method for Dynamically Deformable Cloth" by Sakaguchi et al. (1994, Transactions of IEICE). Regarding the plane expansion method using the finite element method, for example, Shimada et al. [4] "Improvement accuracy of free-form surface expansion" (1986, Proceedings of the IPSJ National Convention), and Wachi's "Synthesis rules for clothing figures" (1984, Bulletin of the Faculty of Life Sciences, Osaka City University). In the case where a three-dimensional element is used to consider the shape of the part in the thickness direction, for example, ignoring deformation in the thickness direction and performing only the above-described calculation considering only the strain energy in the plane direction, Can be expanded. [Embodiment 3] Next, a description will be given of a modified clothing parts data creating means (110) according to a third embodiment of the present invention.

In the present embodiment, based on the body shape data used when creating the deformed clothing shape data and the clothing part deformation rule registered in advance in the clothing part data storage means (115), the deformation is performed. The transformed clothing parts data is created by transforming the clothing parts data that is the basis of the clothing shape data.

FIG. 1 shows a method of creating deformed clothing shape data.
This will be described with reference to 1 and 12.

FIG. 11 shows an example of clothing part data. In FIG. 11A, a, b, c
Is a special point that defines the shape of the clothing part data (hereinafter, referred to as a feature point of the part data). Deformation rules corresponding to the feature points of the part data are defined in advance. FIG. 12 shows an example of the deformation rule. In FIG. 12, a symbol Δ represents a difference, and Δx
Represents displacement in the x direction, and Δbust represents the difference between the bust before deformation and the bust after deformation. The transformation rule is defined for each part required to define the transformation of the clothing part data. For example, a represents a neck point, b represents a shoulder point, and c represents a front center of a hem. The feature point of the parts data is as follows when creating the pattern CAD data.
Set it.

The body shape data used when creating the deformed clothing shape data is, for example, 160 cm tall, 85 cm bust,
In the case of a waist of 65 cm and a hip of 90 cm, those numerical values are substituted into the deformation rule, and the positions of the feature points of the parts data corresponding to the body data are calculated. Then, based on the calculated values, the feature points a, b, and c of the part data are moved to a ', b', and c '(FIG. 11B), and then other points and lines constituting the part data are moved. By moving and deforming to correspond to the movement of the feature point (C in FIG. 11),
The transformed part data, that is, transformed clothing part data is created.

Note that the deformation rules of the feature points of the part data can be obtained by statistically processing various body types and the corresponding pattern CAD data. In the grading system, the number pattern is developed from the standard body pattern (when No. 9 is standardized, the pattern data of
There are two types, one that performs the transformation into a pattern such as No. 1 and No. 13) and the other that creates a personal pattern from a standard pattern. Here, the latter uses a personalized grading system that creates the individual pattern. The personalized grading system transforms the standard body pattern based on the entered data when the customer's personal body or the size specification of the details of the clothes (for example, how much to extend the height or how many cm to shift the pocket position) is input. Then, an individual body pattern is created. The grading method is described in, for example, Industrial Pattern Guidebook (Edited by Amiko Fashions), pp. 217-225, Tokuho 4-23.
001 and the like.

In the above, an example in which the present invention is applied to creation of part data of clothes has been described. However, the present invention is not limited to this, and can be applied to clothing such as hats, aprons, and gloves. Further, in the above embodiment, an example in which the patterner uses the device for creating the part data of the clothing of the present invention has been described, but the device for creating the part data of the clothing of the present invention from home using the Internet or the like is described.
