DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing an embodiment of a clothing pattern making system according to the present invention.

The clothing pattern creation system shown in FIG. 1 is a stand-alone configuration, and creates a clothing pattern according to the customer's personal figure using a CG three-dimensional image. As will be described later, the pattern making device 1
A human body model (three-dimensional image; hereinafter, referred to as a personal body model) adapted to the customer's individual body shape in a three-dimensional virtual space by the user and creates desired clothes (three-dimensional image) for this human body model In addition, since a plurality of patterns forming the garment are raised from the garment, the stencil can be easily and easily made by using a conventional CAD system dedicated to apparel. It can be effectively used as a tool to support the design of a pattern in an order-made system for clothes in department stores, boutiques, and mail-order sales, and as a support tool for factory boutique, which is a recent new form.

Note that the three-dimensional image referred to here corresponds to, for example, an image obtained by photographing a human model with a camera under an appropriate amella angle and lighting. You can see.

Before explaining the configuration of the clothing pattern making apparatus 1, an outline of a pattern making method of the clothing pattern making apparatus 1 will be briefly described with reference to FIGS.

The pattern making apparatus 1 comprises a plurality of data which form three-dimensional image data of a standard human figure model (hereinafter referred to as a standard human model) and clothes (hereinafter referred to as standard clothing) adapted to the standard human model. As shown in FIG. 2, each pattern D constituting the standard clothing C (in the virtual space, is flat in the virtual space of the CG) as shown in FIG. ) Is pressed against the corresponding part of the standard body model M to deform it into a required shape.
The three-dimensional image of the standard clothes C attached to the standard body model M is created by linking (transformed into a three-dimensional image) based on predetermined sewing conditions. Then, a first projection function T indicating the correspondence between the standard body model M and the standard clothing C is calculated using the three-dimensional images.

The first projection function T represents, for example, a three-dimensional image of the standard body model M by a surface model using triangular patches, while a three-dimensional image of the standard clothing C is expressed by a standard grid in which square grids are neatly arranged. Assuming that a plurality of grid points are provided in the image after being divided, the mutual positional relationship between each grid point of the standard clothing C and each triangular patch of the standard body model M (that is, the standard relative to the surface of the standard body model M) It shows the positional relationship between the grid points of the standard clothes C and the triangular patches of the standard body model M (the coordinates of the grid points in the coordinates provided in the virtual space and the triangular patches of the triangular patches). (Correspondence with coordinates) is calculated in a list format.

Subsequently, the pattern making device 1 is shown in FIG.
As shown in (b), the three-dimensional image of the standard body type model M is externally input with respect to the customer's body type (for example, information on height, shoulder width, chest measurement, waist measurement, waist measurement, etc., hereinafter referred to as body information). ) To create a three-dimensional image of the individual body model M ′,
Then, a second projection function F indicating the correspondence between M and the standard body model is calculated.

The second projection function F is based on the mutual positional relationship between the triangular patches forming the surface of the standard body model M and the triangular patches forming the surface of the individual body model M '(ie, the standard body model M). M indicates the displacement vector amount of each triangular patch constituting the surface of M. The positional relationship between the triangular patch of the standard body model M and the individual body model M ′ (the coordinates of the two triangular patches at coordinates provided in the virtual space). Specific data indicating the relationship (coordinate correspondence) is calculated in a list format.

Subsequently, as shown in FIG. 4, the pattern creating apparatus 1 deforms the standard clothing C using the first and second projection functions to thereby adjust the clothing C adapted to the size of the individual body model M '. (Hereinafter, this garment is referred to as a special garment.), And a three-dimensional image of the special garment C 'is used to generate a two-dimensional image of a pattern D' constituting the garment.

FIG. 5 shows a mathematical model of the above pattern making method. In the figure, symbols C, C ',
D, D ', M, M', T, F are the same as described above. The projection function S is a function for projecting the image of the pattern D on the image of the standard clothing C when the image of the standard clothing C is created from the image of the pattern D. The projection function Z is a function for projecting the image of the special clothing C 'onto the image of the pattern D' when creating an image of the pattern D 'from the image of the special clothing C'.
The projection function G is a function for projecting the image of the standard clothing C necessary for creating an image of the special clothing C 'from the image of the standard clothing C onto the image of the special clothing C'.

If the projection function G is known, a standard garment C is created for the standard body model M, and the image of the standard garment C is transformed by using the projection function G. However, since the projection function G includes the deformation parameters of the standard garment C based on the customer's body type, the projection function G cannot be known, and the image of the special garment C ′ is obtained from the image of the standard garment C. It is not possible. Even if the customer's body information is obtained for each customer, it is not easy to determine the projection function G from the customer's body information because this body information is not information directly related to the special clothing C '.

On the other hand, the standard body model M
A three-dimensional image of the standard clothing C can be created with respect to the three-dimensional image of the individual, and the three-dimensional image of the standard body model M is transformed based on the customer's body information to create a three-dimensional image of the individual body model M ′. Therefore, if the projection relationship between the standard body model M and the individual body model M ′ is applied to the standard clothes C, an image of the specially made clothes C ′ can be obtained. Therefore, in the paper pattern making apparatus 1, by tracing the path from the standard clothing C to the standard body model M, the individual body model M 'and the special clothing C', an image of the special clothing C 'by the projection function G is equivalently created. Trying to achieve.

When the above-described projection relation is mathematically expressed, C = T (M) = S (D, M) (1) M = T （ ¹ (C) M ′ = F (M) = F (T ^{1 1} (C)) (2) C ′ = T (M ′) = T (F (M)) = T (F (T− ¹ (C))) (3) D ′ = Z (C ′) , E) (4).

The above equation (1) is obtained by applying the projection function T to the image information of the standard figure M.
Further, it is shown that a three-dimensional image of the standard clothes C can be obtained by applying the projection function S to the image information of the pattern D. Equation (2) is obtained by further applying the projection function F to the image information of the standard body model M obtained by applying the inverse function T ~ ¹ of the projection function T to the image information of the standard clothes C. This shows that a three-dimensional image of the model M ′ can be obtained. Equation (3) shows that the projection function T is applied to the image information of the individual body type M ′ obtained by equation (2) to obtain the third order of the special clothing C ′. This indicates that an original image can be obtained. Equation (4) expresses the constraint information of the pattern (flatness, left-right symmetry, partial straightness, partial curvedness, matching at the time of suturing) to the image information of the special garment C ′ obtained by equation (3). It is shown that a two-dimensional image of the pattern D 'can be obtained by applying the projection function S in consideration of conditions such as sex.

The standard clothing image creating section 201 creates a three-dimensional image of the standard clothing C by a method disclosed in, for example, Japanese Patent Application Laid-Open No. H8-44785 (method of forming a three-dimensional shape of clothing). Although a detailed description of this image creation method is omitted, the outline is that a plurality of patterns D constituting the clothes are arranged at corresponding positions around the model, and each pattern is pressed against the model so that the temporary three-dimensional clothes are formed. After the shape is formed, the standard clothing C is simulated by sewing the pattern papers together to create a clothing.

A three-dimensional image of the standard clothing C is created by performing image processing so as to perform sewing. In this image processing,
Each pattern D is deformed based on the cloth information input from the input unit 5, and a sewing process is performed based on the sewing information. Then, the three-dimensional image of the standard clothes is stored in the external storage device 7.

The model image creation unit 202 reads out the image data of the standard body model M from the external storage device 7 to the RAM 4 and performs necessary transformation processing on the image data based on the customer body information input from the input unit 5.

The first projection function calculation unit 203 calculates the first projection function T using the image data of the standard clothing C and the image data of the standard body type model M created by the standard clothing image creation unit 201. The three-dimensional image of the standard body model M is represented by a surface model using triangular patches as described above. The standard body model M is represented by a surface model using triangular patches in order to accurately represent the model body with a small number of data. On the other hand, as described above, the three-dimensional image of the standard clothing C is divided by the standard grid in which the square lattices are neatly arranged, and a plurality of grid points are provided in the surface of the clothing. The three-dimensional image of the standard clothes C is formed by a square grid because it is close to the cloth structure (weft, warp) that is the material of the clothes, suitable for grid patterning, and sewing processing of the pattern in a virtual space. Is easy.

The first projection function calculation unit 203 calculates the standard clothes C

The grid point ai with respect to the grid point ci is calculated by calculating the grid point ai of the standard body model M having a normal vector in a direction opposite to the normal direction of the grid point ci. If the grid point ai does not exist in the normal direction of the grid point ci, as shown in FIG.
A cubic minute frame Q centered on the grid point ci is set, and the size of the small frame is enlarged to be opposite to the normal direction of the grid point ci of the standard clothes C to be initially included in the small frame. A lattice point ai of the standard body model M having a normal vector in the direction becomes a lattice point corresponding to the lattice point ci. In addition,

Since the three-dimensional image of the individual body model M ′ is a modification of the three-dimensional image of the standard body model M based on the customer's body information, a plurality of triangular patches constituting the three-dimensional image of the standard body model M are obtained. Each grid point a

At this time, for example, a pattern that needs to preserve left-right symmetry, such as a front part of clothes. As shown in Fig. 10, an average plane shape that is symmetrical with respect to the line of symmetry is determined as shown in Fig. 10, and the pattern D 'is developed based on this plane shape. Under the symmetry constraint, each grid point c
The three-dimensional pattern paper D ′ of the front body is developed into a two-dimensional pattern paper D ″ while preserving the distance (length) between i.

Further, as shown in FIG. 11, the portion d1 "corresponding to the straight portion d1 in the original pattern D becomes a straight line, and the portion d2" corresponding to the curved portion d2 becomes the straight portion.

A three-dimensional image of clothes C 'is created (step #)
9). Then, the three-dimensional image of the special garment C 'is separated into three-dimensional images of a plurality of patterns D' constituting the garment, and the three-dimensional images of the respective patterns D 'are symmetrically and partially linearized. Then, a desired pattern paper D ″ is created by developing the image into a two-dimensional image under the constraint conditions of the partial curvilinearity.
