Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides a device for obtaining a simulated fabric image close to the finished state of the fabric at the stage of planning the fabric, and a device for obtaining a simulated fabric image that is close to the finished state of the fabric at the stage of actually manufacturing the fabric. The present invention also relates to a device for controlling a patterning device of a loom based on the simulated fabric image.

[Prior Art and Problems to be Solved by the Invention] In the conventional computer-based textile pattern creation system, at the stage of planning the textile, the design drawings or design drawings drawn by the designer are read using a drum scanner or the like and displayed on a display. However, in the display image, each thread that makes up the fabric is expressed as a line or cylindrical shape, or the intersecting position of threads is expressed as a point, etc., which is different from the actual thread. Also, because it was not possible to express the fine shapes and delicate colors of the fabric, there were restrictions on expressing a state close to the finished weaving of the actual fabric.
In other words, the above expression is possible for relatively high-density fabrics using fine-count yarns, but it is difficult to express the above expressions for coarse-density fabrics using thick-count yarns, especially in recent years. The above expression could hardly be applied to textiles using decorative threads, which have become more popular.

Furthermore, Japanese Patent Application Laid-Open No. 18964/1983 discloses a technology in which a design drawing drawn by a designer is read by a television camera, a part or all of this design is freely changed by an amendment operation, and the design is monitored on a cathode ray tube. However, there is no disclosure of any technology for reading actual threads or fabrics and synthesizing their images into design drawings as in the present invention. It was difficult to express a state that was close to rising.

In view of the current situation, the present invention creates a clear simulated fabric image that is close to the woven state of the fabric, expressing the minute shapes and subtle colors of the actual thread or fabric at the stage of planning the fabric, By displaying this simulated fabric image on a display, print, or film, it is possible to accurately predict the weaving state of the fabric, thereby improving the efficiency of fabric planning, and to actually make the fabric. The purpose is to promote the development of new products by outputting control data for the patterning device of the loom based on the simulated fabric image at the manufacturing stage.

[Means for Solving the Problems] In order to achieve the above object, the following measures were taken in the present invention.

The fabric weaving simulation device according to claim 1 comprises:
means for reading the design drawing, means for storing the read design drawing, means for optically reading the actual thread or fabric, and the image of the read thread or fabric corresponding to one unit of the design drawing. means for dividing an image into units of size, means for storing the image of the divided thread or fabric; A means for creating a simulated textile image close to the finished state of the actual textile by selecting and composing one unit of textile images, and a means for displaying the simulated textile image on a display, print or film. The configuration was as follows.

The textile pattern control device according to claim 2 includes means for reading a design diagram, a means for storing the read design diagram, a means for optically reading the actual thread or textile, and a means for reading the read design diagram. or means for dividing the image of the textile into units each having a size corresponding to one unit of the design drawing, means for storing the image of the thread or textile into which the image has been divided, and the stored design drawing. means for creating a simulated textile image close to the finished state of the actual textile by selecting and composing one unit of the stored image of the yarn or textile for each unit of the textile; and means for outputting control data for the patterning device of the loom based on the above.

[Function] In the fabric weaving simulation display device and fabric pattern control device described above, an image of the actual thread or fabric is synthesized with the design drawing, so the actual image representing the shape and color of the actual thread or fabric is displayed. A clear simulated fabric image that closely resembles the weaving of a fabric is created.

[Example] Hereinafter, an example embodying the present invention will be described with reference to FIGS. 1 to 4. The apparatus configuration of this embodiment is as shown in FIG.

The electronic control device 1 consists of a main body equipped with a microcomputer or a minicomputer, or both, having a large capacity of RAM, a character display, a keyboard, etc., and is equipped with an interface for external devices 2 to 13, and a color display. This is a device that has an adjustment function.

A drum scanner 2 and a television camera 3 are examples of devices that optically read the surface of an actual thread or fabric.

Devices for reading the organization chart include a paper card reader 6 and a floppy disk device 5.

The drum scanner 2, the television camera 3, and the paper tape are used as devices for reading design drawings or their original design drawings (in this specification, when simply referred to as "design drawings", these design drawings, etc. are also included). There is a reader 4 and the floppy disk device 5.

A digitizer 7 is used as an auxiliary device for correcting the read organization chart or design drawing, correcting the read image of the actual thread or fabric (details will be described later), and processing the image division. . The electronic control unit 1 is responsible for these functions such as correction and image division. Here, "image division"
This means that the image of the read thread or fabric is divided into units each having a size corresponding to one unit of the design drawing.

There are a disk 8 and an external disk device 9 as devices for storing the read image of the actual thread or fabric as well as the read organization chart or design drawing. The disk 8 is a large-capacity fixed disk that can respond to the electronic control device 1 in real time. The external disk device 9 is a large-capacity external storage device, such as a magnetic disk device or an optical disk device.

The electronic control device 1 selects and synthesizes one unit of the stored image of the yarn or fabric for each unit of the stored design drawing, thereby creating a weaving state close to the actual woven fabric. Programmed to create simulated textile images.

A high-resolution color display 10 is a device for displaying the simulated textile image synthesized by the electronic control device 1 on a screen. Further, there is a color hard copy device 11 (color printer, color photographing device, etc.) as a device for printing the simulated fabric image on paper as a hard copy or as a device for creating a color film.

In addition, in order to actually manufacture the fabric planned as described above, a paper tape puncher is used as a device that outputs control data for a patterning device such as a dobby device or a jiacard device attached to a loom based on the simulated fabric image. 12, floppy disk device 5,
There is an output data interface 13. For example, the paper tape output from the paper tape puncher 12 is converted into a paper card for a Dobby device, a pattern paper for a Jia card device, etc. by a piano machine equipped with a paper tape reader. Further, the output data interface 13 is an interface that can be connected to a device that directly controls the patterning device.

Next, the contents of work performed by an embodiment of this device configuration will be explained.

(1) First, the organization chart is read by passing the paper card into which the data has been entered into the paper card reader 6. The design drawing is optically read by a drum scanner 2 or a television camera 3. These data are input to the electronic control device 1.

The above operation is performed by using the paper tape reader 4 if there is a paper tape on which organizational chart and design data have already been input, the floppy disk device 5 if there is a floppy disk, and the floppy disk device 5 if a magnetic tape, magnetic disk, or optical disk is used. If so, the external disk device 9 can be used instead.

For the design drawings that have been read, the digitizer 7 can be used to invert, overlay, blur, repeat, enlarge, reduce, etc.
Correction processing such as symmetry may be performed.

(2) Next, an image of the actual yarn 14 or fabric 15 is optically read by the drum scanner 2 or the television camera 3 and input to the electronic control device 1.
FIG. 2 shows an example of an image 16 of the thread 14 (design thread is used) or an image 17 of the fabric 15.

These scanned images 16 and 17 include
Add the following or processing as necessary. Note that these processes are not essential to the present invention.

The parts of images 16 and 17 are enlarged to correct the details. "Modification of details" means, for example, when combining these images 16 and 17 with a design drawing in a later process, a thread is added between one unit of the combined images 16 and 17 and one unit next to it. Or so that the joints of the fabric do not shift,
This refers to modifying a portion of these images 16 and 17.

Based on the input color, the digitizer 7 is operated to designate a color area to correspond to the actual color change of the thread 14. "Specifying a color area to correspond to the color change of the actual thread 14" means, for example, that the actual thread 14 has bright and dark parts depending on how the light rays hit it, so it corresponds to this brightness change. Let's thread 1
This refers to specifying bright areas and dark areas in the image 16 of 4.

Based on images 16 and 17, replace one of the threads composing them with another thread 18,
Change the density of the weft threads.

Next, the image 16 of the thread 14 or the image 17 of the fabric 15 is controlled by the electronic control device 1.
The image is divided into units each having a size corresponding to one unit of the design drawing.

Image 1 of the thread 14 divided into images in this way
6 or the image 17 of the fabric 15 is stored on the disk 8 as well as on an external disk device 9.

(3) Next, input the stored design drawing and the images 16 and 17 of the thread or fabric into the main body memory of the electronic control device 1, and perform the steps for each unit of the design drawing.
By selecting one unit of the images of the threads or fabrics 16 and 17 and composing them, a simulated fabric image close to the finished state of the actual fabric is created on the display.

Furthermore, to explain this part using the jacquard fabric shown in Fig. 3 as an example, design drawing 19
is composed of two types of units 20 and 21, the organization chart of each unit 20 and 21 is shown at 22 and 23, and the created simulated fabric image is as shown at 24 and 25. Furthermore, if, for example, a 4×4 unit at the lower left end of the design drawing 19 is extracted, this is represented as a part of the enlarged design drawing as shown in FIG. 4a. Unit 21 shown in black part in Figure 4a
Looking at the correspondence between the set of and the simulated textile image 23 in Figure 4b (which is equivalent to the simulated textile image 25 in Figure 3), it is found that when the image subdivision unit is 2 x 2 at the organizational chart level. In this case, 1A in FIG. 4a corresponds to 1'A' in the simulated fabric image 26 in FIG. 4b,
Similarly, 1B corresponds to 1'B' and 1C corresponds to 1'C', and the entire black area in FIG. 4a falls within the thick frame in FIG. 4b.

Although the actual image synthesis is performed at a fineness several times higher than that of the simulated fabric image 26 (the simulated fabric image 26 is simplified for convenience of explanation), each unit of the design drawing 19 is On the other hand, one unit of the yarn or fabric images 16, 17 is 1' in the horizontal direction.
A', 1'B', 1'C', 1'D'... and electronic control device 1
When it reaches the end of the image input unit, it repeats the same input for the next example. This method is also applied in the vertical direction. In this way, for each unit of the design drawing 19, one image of thread or fabric
One unit of 6,17 is selected and combined, taken out to the graphics control memory, and expressed on the display.

Using the color adjustment function for the simulated fabric image 26 created in this way, the color of the threads used in the fabric is changed to observe changes in the color of the fabric. The color adjustment function is based on an image expressed in shading using shading of a single color, and superimposes colors on this image to control the color for each color area. In this way, when a simulated fabric image that satisfies the planner is obtained, the image is hard-copied onto paper or color film by the color hard copy device 11.

In order to actually produce the simulated fabric image thus completed as a fabric, the control data of the patterning device of the loom is output to a floppy disk by the floppy disk device 6 or to a paper tape by the paper tape puncher 12. These are converted into paper cards for the Dobby device or patterned paper cards for the Jia Card device by a piano machine equipped with a floppy disk device or a paper tape reader. Furthermore, the output data interface 13 can be used to directly control the patterning device.

Note that the reference thread or fabric image and the simulated fabric image completed by combining these images into a design drawing are stored in the external disk device 9.

Test Example The following Samples 1 and 2 were read by a scanner, and the simulated fabric images created as described above were displayed on a 1024 x 1024 dot display. As a result, Sample 1 was able to express well the feel of the mall yarn in the weft, the metallic luster of the lame yarn, and the soft luster of the rayon yarn in the weft. In addition, in Sample 2, which used a special pulp-processed material, each strand of the straw-like material could be expressed quite clearly, and an image close to the real thing was obtained for the wall covering material as a whole.

Furthermore, the photographs of these simulated textile images obtained with the camera were comparable to photographs of the actual textile.
