Abstract

PROBLEM TO BE SOLVED: To easily generate deformed three-dimensional shape data in a short time by moving a dot position between the start position and end position of deformation of three-dimensional shape data of the body according to deformation quantity data and a line direction. SOLUTION: To generate data of a deformed clothing shape, deformation quantity data is inputted to a personal computer first (901) and data used for deformation calculation and the position of the shape of an object clothing surface are loaded to a memory (902 and 903). Shape data of clothing is represented as a set of plane polygonal fine elements consisting of nodes in a three-dimensional space and a fine element is composed of nodes. Then it is confirmed whether a node is between the start and end positions of deformation (904), the distance between an object node to be calculated in a deformation object area and the deformation start position is calculated (905), and the deformation quantity of the object node is calculated (906). Then the position of the node is moved and the position after the movement is calculated (907). Thus, the calculation is repeated until no node to be deformed is left to find the shape of the clothing.

2. Description of the Related Art Conventionally, it is difficult to predict the final finished state when deciding the design of a garment or the material to be applied in easy-to-order garment sales of the garment. Sometimes it was different. Also, fearing that a product different from the one that the customer had imagined will be completed, hesitate to manufacture and purchase new materials or clothing completely different from the customer's clothing, or place the easy order itself. In some cases it was not available.

In order to solve such a problem, there has been proposed a method of displaying and confirming the completed state of clothing using a computer. For example, conventionally, there is a method of confirming the completed state of clothes by combining and displaying images of various materials using a computer using two-dimensional images such as photographs and illustrations. As such a method, Japanese Patent Application Laid-Open No. 55-93808 discloses an image in which an image of a material is applied to the shape of the clothing based on image data of the material and data defining a desired shape of the clothing. , A method of displaying on a display is disclosed.

In the above-described method of setting the color pattern of the material of the clothes in the two-dimensional image to the color pattern of another material, it is possible to judge the quality of the coordination of the color and the pattern. I cannot confirm the difference in silhouette. In particular, in the case of women's clothing, there are many clothes with a high drape property, which is a problem.

[0005] To solve this problem, a method of defining a three-dimensional model of clothing on a computer and predicting and calculating the clothing state of clothing by mechanical calculation taking physical properties of the material into consideration (hereinafter referred to as a physical property of the material). Determining the shape of clothes by mechanical calculation is called dressing calculation).

By the way, in the case of the easy order of clothes, the order of changing the length of the skirt and pants, the sleeve length of the jacket, the position and size of the pocket, etc. is often received according to the customer's preference. . In order to check the finished condition of the clothes on a computer, it is preferable that the clothes reflect the silhouette and drape of the clothes due to the difference in the color pattern of the material, the physical properties of the material, and a part of the design of these clothes Needless to say. Depending on the design of the garment, the finished image may change significantly even if it is partially deformed, and it is important to display the completed state of the garment after the deformation.

[0007] Even by the above-described dressing calculation, the two-dimensional shape data of the clothes used for the calculation (generally created based on the pattern data) is converted into a pattern CAD having knowledge of pattern creation and a function of partially deforming the pattern. By performing a dressing calculation based on the pattern data after the deformation, it is possible to confirm the completed state of the clothes reflecting the partial deformation of the clothes. However, an enormous amount of calculation is required to determine the clothing state of clothes by clothing calculation, and it often takes tens of minutes to several hours to calculate the clothing state of one piece of clothing.

The garment may be attached to an order sheet for confirmation when ordering the garment.

In step 808, the detailed individual body shape of the customer is measured for manufacturing the garment, and the garment is manufactured based on the garment specifications and the measuring information determined in step 805. If the sewing factory is located at a different location from the dealer, the order sheet may be transmitted to the sewing factory using a network or the like, or the order sheet may be transmitted to the sewing factory using a facsimile.

In this embodiment, the material of the clothes is selected after the design of the clothes is selected. Alternatively, the material of the clothes may be selected and then the design of the clothes may be selected.

As described above, the customer determines the specifications of the clothes, creates a virtual fitting situation in that case using the above-mentioned shape data creating device, displays it on the screen, and based on the display, the customer further selects the desired specifications. , And the same virtual fitting is repeated, so that the optimal clothing specification can be finally determined. When the garment is manufactured based on the finally determined specifications in this manner, the garment as imagined by the customer can be manufactured quickly and reliably.

Next, the object shape deforming means (114) will be described in detail with reference to three embodiments. [Embodiment 1] A method of creating shape data of an object in which the shape of clothing is deformed in the body axis direction by the object shape deforming means of the present invention will be described. This deformation method is suitable for, for example, deformation of the length of a skirt or pants, deformation of the sleeve length of a jacket or the like, or deformation of a legible length. Here, the deformation of the height of the skirt (up and down of the height) will be described as an example using the flowchart of FIG.

In step 901, deformation amount data is input. Deformation amount data is data of how many cm the skirt length goes up and down.
If you want to extend the cm length, enter + 10cm.

In step 902, data used for deformation calculation is loaded into the memory of the personal computer (101). As the data used for deformation calculation,
There are three-dimensional shape data of the clothing to be transformed, straight line data used for the transformation, and data on the starting and ending positions of the transformation. In the present embodiment, the body axis is used as the straight line data used for the deformation. In the case of the skirt height deformation, a straight line (402) passing near the center of the left and right legs is used. In the case of the skirt height deformation, in this embodiment, the data relating to the starting position and the ending position of the deformation are the hip line and the skirt of the skirt, respectively. The line data used for the deformation and the data on the start and end positions of the deformation differ depending on the deformed part (sleeve length, best-looking length, skirt length, etc.). It may be stored in the storage means of the device (106). Also, in this embodiment example,
Although straight line data is used as data for defining the direction of deformation, curve data may be used instead of a straight line. When using the curve data, the curve data can be defined as a line connecting a plurality of points smoothly. At this time, the direction of the curve can be defined as the direction of a minute line segment near each point of the curve. It is also conceivable to use a group of straight lines connecting a number of points.

In step 903, the shape portion of the clothing surface to be subjected to the deformation calculation is loaded into the memory. In this embodiment, the clothing shape data is represented by a set of planar polygonal microelements composed of coordinate points (nodes) in a three-dimensional space as shown in FIG. 3 including the thickness of the clothes
A three-dimensional model using a three-dimensional pyramid element or a three-dimensional shape may be used. The minute element is composed of a plurality of nodes, but in the present embodiment, the nodes are to be deformed. Step 903 until there are no nodes in the shape of the clothes to be deformed
And step 907 are repeated, and when there are no more nodes to be transformed, the transformation calculation is completed.

In step 904, it is checked whether or not the node is within the deformation target area, that is, whether or not it is between the start position and the end position of the deformation. If it is within the deformation target area, the process proceeds to step 905;
Returning to step 903, the next element is transformed.

In step 905, the distance a between the node to be subjected to the deformation calculation and the starting position of the deformation is calculated.
The calculated distance is a distance in a direction along a straight line or a curve used for deformation.

In step 906, the deformation amount d of the node to be subjected to the deformation calculation is calculated. The amount of deformation is calculated by the following formula.

D = k * (a / b) * x (Equation 1) where b is the distance between the start position and the end position of the deformation in the linear direction used for the deformation. x is step 901
Is the deformation amount data input in step (1). k is a coefficient, usually 1
Where k may be defined as a function of a. For example,
If you want to deform the skirt length while keeping the shape near the skirt of the skirt as it is, if a becomes closer to b than a certain value, set the value of k to zero, it will be possible to deform the length without deforming the skirt it can.

In step 907, the position of the node is moved. The moved node is calculated by the following equation.

P ′ = P + d * L (Equation 2) where P is a three-dimensional vector representing the position of the node before movement, P ′ is a three-dimensional vector representing the position of the node after movement, L
Is a direction vector (size 1) of a straight line used for deformation. This completes the deformation calculation of one node, and returns to step 903 to calculate the deformation of the next node.

When the skirt length is deformed by the method described above,
As shown in FIG. 10, shape data in which the skirt length is changed can be created. The calculation time at this time is much shorter than obtaining the shape of the clothing by the clothing calculation. In addition, this deformation method is an approximate deformation, and although the shape after the deformation has an error compared with the shape of the actual product or the shape of the clothing recalculated by the dressing calculation, the present inventors have investigated. According to this, it is a level that is sufficiently useful to imagine the finished state of clothing. [Embodiment 2] A method of creating shape data of an object in which the shape of clothing is deformed in the centrifugal direction of the body axis by the object shape deforming means of the present invention will be described. The centrifugal direction refers to the direction of any half-line extending outward from the center at the intersection of the body axis and the plane in a plane perpendicular to the body axis. This deformation method is suitable for, for example, deformation of a skirt or dress. Here, description will be made with reference to the flowchart of FIG. 11 taking as an example the deformation of the skirt (perimeter of the skirt).

In step 1101, deformation amount data is input. The deformation amount data specifies how many centimeters to enlarge or reduce the skirt arrangement. For example, if it is desired to expand the skirt arrangement by 3 cm according to the customer's preference, +3
Enter cm.

In step 1102, data used for the deformation calculation is loaded into the memory of the personal computer (101). The data used for the deformation calculation includes three-dimensional shape data of the clothing to be deformed, straight line data used for the deformation, and data on the start position and the end position of the deformation. In the present embodiment, the body axis is used as the straight line data used for the deformation. In the case of changing the skirt length, a straight line (302) passing near the center of the left and right legs is used. Further, in the case of the turning deformation, in this embodiment, the data regarding the starting position and the ending position of the deformation are the hip line and the skirt of the skirt, respectively.

In step 1103, the nodes of the shape of the clothes to be subjected to the deformation calculation are loaded into the memory. Step 1 until there are no more nodes in the shape of the clothing to be transformed
Steps 1107 to 103 are repeated, and when there are no more nodes to be deformed, the deformation calculation is completed.

In step 1104, it is checked whether or not the node is within the deformation target area, that is, whether or not it is between the deformation start position and the deformation end position. If it is within the deformation target area, the process proceeds to step 905. If it is not the deformation target, the process returns to step 1103 to deform the next element.

In step 1105, the distance a between the node to be subjected to the deformation calculation and the starting position of the deformation is calculated. The calculated distance is a distance in the direction of a straight line or a curve used for deformation.

In step 1106, the deformation amount d of the node to be subjected to the deformation calculation is calculated. The amount of deformation is calculated by the following formula.

D = k * (a / b) * x (Equation 3) where b is the distance between the starting position and the ending position of the deformation along the straight line used for the deformation. . x is the deformation amount data input in step 901. k is a coefficient,
Although usually a constant, k may be defined as a function of a.
In the present embodiment, since the amount of deformation of the turn is the amount of deformation of the circumference, k is set to 1 / π (π is the circular constant).

In step 1107, the position of the node is moved. The moved node is calculated by the following equation.

P ′ = P + d * N (Equation 4) where P is a three-dimensional vector representing the position of the node before movement, P ′ is a three-dimensional vector representing the position of the node after movement, N
Is a direction vector (size 1) in the centrifugal direction of a straight line used for deformation. FIG. 12 shows an explanatory diagram in which the skirt is sliced to explain (Equation 4). With this, the deformation calculation of one node is completed, and the process returns to step 1103 in order to calculate the deformation of the next node.

By deforming the skirt arrangement by the above-described method, it is possible to create shape data in which the skirt arrangement is enlarged or reduced as shown in FIG. [Embodiment 3] A method of deforming the three-dimensional shape of an object in close contact with clothes by the object shape deforming means of the present invention will be described. To be in close contact with the garment means that the garment is located at a position separated from the surface along the surface shape of the garment by 0 or by a minute distance compared to the two-dimensional spread of the adhered object. This deformation method is suitable for, for example, changing the size, shape, and position of a pocket. Here, description will be given using the flowchart of FIG. 14 by taking the pocket deformation of the jacket as an example.

In step 1401, deformation data is input. The deformation amount data is data indicating how many centimeters to move the position of the pocket up and down or in the circumferential direction, and data indicating how many cm the width and depth of the pocket should be enlarged or reduced.

At step 1402, data used for the deformation calculation is loaded into the memory of the personal computer (101). As data used for the deformation calculation, three-dimensional shape data of the clothing to be deformed, two-dimensional shape data of the clothing corresponding to the three-dimensional shape data of the clothing,
There are pocket two-dimensional shape data and pocket attachment data that defines how the pocket two-dimensional shape data is attached to the clothing two-dimensional shape data. The pocket attachment data corresponds to the two-dimensional position definition data in the present invention. In this embodiment, the pocket attachment information is information relating to the amount of movement and information relating to the amount of rotation. FIG. 15 shows the two-dimensional shape data of the clothes,
Examples of dimensional shape data and pocket attachment data are shown.
In FIG. 15, reference numeral 1501 denotes two-dimensional shape data of the surface of the jacket in the best view, 1502 denotes two-dimensional shape data of the close contact surface of the pocket in the best view, and 1503 denotes pocket attachment information. The three-dimensional shape data of the garment is obtained by dressing calculation of the two-dimensional shape data of the garment, and the elements and nodes constituting the two-dimensional shape data are:
There is a one-to-one correspondence with the elements and nodes constituting the three-dimensional shape data.

In step 1403, step 14
01 in accordance with the deformation amount data input in step S011, pocket mounting information, (1503),
The dimensional shape data (1502) is changed. For example, when the deformation amount data reduces the pocket attachment position by 1 cm and reduces the width of the pocket by 1 cm, the pocket attachment data (1503) and the two-dimensional shape data (1502) of the pocket contact surface are as shown in FIG. In the figure, the black dot moves to the white dot). In the present embodiment, moving the attachment position of the pocket in the head direction is referred to as raising, and moving in the skirt direction is referred to as lowering. Increasing the width of the pocket is called increasing the width, and decreasing the width of the pocket is called reducing the width.

In step 1404, step 14
03, the pocket attachment information after deformation (160
According to 3), in step 1403, the two-dimensional shape data (1602) of the contact surface of the deformed pocket is moved to the pocket mounting position of the two-dimensional shape data (1601) of the outermost surface of the jacket. FIG. 17 shows a state after moving the two-dimensional shape data of the pocket. In FIG.
1701 is the two-dimensional shape data of the outermost surface of the jacket,
Reference numeral 1702 denotes two-dimensional shape data of the contact surface of the pocket.

At step 1405, the nodes of the two-dimensional shape of the pocket to be deformed are loaded into the memory.
Steps 1405 to 1409 are repeated until there are no nodes in the two-dimensional shape of the pocket to be deformed. When there are no nodes to be deformed, the deformation calculation is completed.

In step 1406, the most suitable element of the jacket which is closest to the node of the pocket to be deformed is searched for, and the nearest point (point responding to the node of the pocket) in the best element of the pocket node is determined. In FIG. 18, the element P of the pocket (1702) to be transformed
The element of the best view (1701) of the jacket closest to is the element
E, and the nearest point of P in element E is Q. In other words, the two-dimensional space represented by the two-dimensional shape data of the best-view surface,
When the two-dimensional space represented by the two-dimensional shape data of the contact surface of the pocket is matched, Q is a point at the same position as P.
Therefore, in FIG. 18, although P and Q coincide, the positions are shifted for the sake of explanation.

In step 1407, a value for specifying the position of Q in the element E is obtained. In this embodiment example, the element is 3
Since a rectangular element is used, as shown in FIG. 19, when vectors representing two sides of the element E are A and B, a coefficient t1 that satisfies Q = t1 * A + t2 * B (Equation 5) , t2 are values specifying the position of Q.

In step 1408, the position Q 'on the three-dimensional shape of the clothing corresponding to Q is determined. Q 'can be calculated by the following equation.

Q ′ = t1 * A ′ + t2 * B ′ (Equation 6) Here, t1 and t2 are values obtained in step 1407.
Also, assuming that the element E ′ on the three-dimensional shape of the clothes corresponding to the element E, A ′ and B ′ are vectors of two sides constituting the element E ′ corresponding to A and B of the element E, respectively. . FIG. 20 shows the relationship between Q and Q ′. 2002 represents the best-looking shape of the jacket in the three-dimensional space, and 2001 represents the best-looking shape of the jacket in the two-dimensional space.
As described above, the position Q ′ in the three-dimensional space can be uniquely obtained from the positional correspondence between E and E ′ and t1 and t2 obtained in the two-dimensional space.

In step 1409, two
A node P ′ of the three-dimensional shape corresponding to the node P of the three-dimensional shape is obtained. P 'can be calculated by the following equation.

P ′ = Q ′ + D (Equation 7) Here, D is a vector value that defines the floating amount of the pocket, and takes a value of 0 or more. In this embodiment, the distance D is used as the distance from the clothes (here, the best view of the jacket) closest to the node of the three-dimensional shape of the pocket before deformation. In addition to this, for example, a method of setting the magnitude of D to a constant value and setting the D direction to the normal direction of Q ′ can be considered. In this case, the pocket is stuck at a position where it is floated by a certain distance from the best view. With this, the deformation calculation of one node is completed, and to calculate the deformation of the next node,
It returns to step 1405.

When the pocket is deformed by the above-described method, the shape data of the clothes whose pocket is deformed can be created as shown in FIG. In FIG. 21, reference numeral 2101 denotes the shape of the clothes before the pocket deformation, and 2102 denotes the shape of the clothes after the pocket deformation. At this time, even if the shape of the clothes (appearance) to which the pocket is attached is curved, the pocket floats along the curved surface by the floating amount D and adheres closely. In the present embodiment, the floating amount D is set to a positive value so that the pockets appear to be slightly lifted three-dimensionally, but may be 0 depending on the close contact object.

As described above, since the calculation of the dressing of the clothes takes an enormous amount of time, the shape of the clothes excluding the pocket is calculated at the time of the calculation of the dressing of the clothes, and the dressing is performed using the method of attaching the pockets. It is also conceivable to attach pockets without performing calculations. In this case, when preparing a three-dimensional shape of clothing having many variations of pocket shapes, the clothing calculation can be performed only once, and the three-dimensional shape data of the clothing for the pocket variations can be created. Since the calculation time of the above-described pocket attachment is much shorter than the time of the wearing calculation, the calculation time can be reduced.

In this embodiment, the shell data in which the object data is defined by the surface shape of the object is used. However, the present invention is not limited to this, and the object data may be solid data having a thickness. In this case, taking pocket mounting as an example,
For the best-looking shape data, if the best-looking shape surface data is used instead of the best-looking shape data, and for the pocket shape data, the surface data of the contact surface of the pocket is used instead of the above-mentioned pocket shape data, the above method is used. Can be attached with the pocket.

In this embodiment, the method of creating the three-dimensional shape data of the pocket has been described as an example. However, the present invention is not limited to this. For example, the three-dimensional shape data of the belt, the three-dimensional It can also be applied to a method of creating data or attaching a button to a three-dimensional shape of clothing or changing a position.

In the above, the example in which the present invention is applied to the easy order of clothes has been described. However, the present invention is not limited to this.
For example, if the present invention is applied to custom-made boots, the shape when the length of the boots is changed can be easily confirmed.

The final specification of the article is determined by visualizing the object data created by the above-described method of creating the object data and displaying an image of the article that has been virtually tried on or virtually prototyped, and based on the determined specification, Is manufactured, the article according to the image can be manufactured without the trouble of actually trying on or producing a prototype.

As described above, the method of creating the shape data of the above embodiment is realized by a computer and a program for operating the computer.
