Description
Technical field
The present invention relates to a kind of textile fabric designing apparatus that is used for designing the yarn dyed fabric decorative pattern that is made into jacquard loom etc., specifically, relate to a kind of design apparatus that utilizes computer graphics techniques to come design textile to use.
Background technology
Traditionally, fabric is divided into PRINTED FABRIC and yarn dyed fabric.PRINTED FABRIC is that impressing pattern forms on the plain cloth that is made into white yarn or dyed yarn.Yarn dyed fabric is made into pattern with dyed yarn and forms.Pattern is fairly simple, during such as glazing bar fabric etc., weaves with dobby machine.When pattern is complicated, then weave with jacquard loom.Tie fabric uses jacquard loom woven often.
Jacquard loom is finished traditional weaving process according to the following steps.
(1) with the colored pattern of drawing fabric.The pattern of finishing is called the pattern original copy.
(2) consider the diameter and the spacing of yarn, determine the number of warp thread and weft yarn.
(3) enlarged drawing similar to the pattern original copy is presented on one section paper, gives each section colouring, have warp thread and weft yarn to intersect the rectangle that forms on the paper.The figure that obtains is called detail of design.
(4) set up jacquard card according to detail of design.Jacquard card is the punched card type.A weft yarn of the corresponding fabric of each jacquard card.Jacquard card is used for controlling the position of warp thread.The number of required jacquard card equals the number of weft yarn.Traditionally, a textile design needs a few thousand sheets jacquard cards.When textile design is complicated, required jacquard card outnumber 10,000.Whether the hole representative that forms on the jacquard card will mention each warp thread.Like this, the hole count that forms on a jacquard card is represented the number of warp thread.
(5) the jacquard card of the being set up jacquard loom of packing into.Jacquard loom when running, warp thread is mentioned according to whether porose on the jacquard card.Repeat every weft yarn and walk step between warp thread, fabric is just weaved out.Weft yarn changes along with decorative pattern.
Opposite with traditional process, developed a kind of CAD (computer-aided design (CAD)) system.In this CAD system, utilize computer graphics techniques, on display device, show and pattern original copy graph of a correspondence.With the rotary drum scanner enlarged drawing of designed pattern original copy is read, and the input computing machine.Various conditions such as the diameter of input such as used warp thread or weft yarn and spacing just can be set up in computing machine and the actual suitable detail of design of section paper.Like this, just can export and set up the data that data that jacquard card uses and control jacquard loom are used.
But, in traditional CAD system, fail to finish automatically comprise design procedure and weave step the institute in steps.This is because the graph data that utilizes computer graphics techniques to set up can not directly be recorded as the pictorial data of setting up detail of design.In other words, the decorative pattern of computing machine foundation can not amplify by amplification coefficient on request.
For example, when producing the fabric that necktie uses, adopt the very thin line of diameter in 1/10 to 1/12mm scope.In this case, during the foundation detail of design corresponding with warp thread and weft count, the size of each section of section paper becomes 0.1mm or littler.In order to represent such detail of design with image, each section will have a data point at least.
On the other hand, in the step that the active computer figure designs, whole image must be presented on the display device.In addition, need take pictures, then editor with image scanner.Like this, the pictorial data ratio is set up detail of design to be processed going back slightly.Like this, the dot density of the pictorial data of taking with image scanner does not match with the dot density of pictorial data requirement.
In order to address this problem, the thick image printing that computing machine is obtained comes out, and sets up the figure of amplification with this, writes down the data of gained then with scanner.Perhaps, read graph data with expensive high resolving power rotary drum scanner from print result.The processing procedure that like this, just needs trouble.As a result, shorten the production required time of product unsatisfactorily.
Summary of the invention
An object of the present invention is to provide a kind of textile fabric designing apparatus, it can finish all production stages that comprise planning/design procedure and weave step automatically, and can shorten widely and comprise that design procedure is until required time of all production stages that product is finished.

Embodiment
Then, one embodiment of the present of invention are described with reference to the accompanying drawings.
Fig. 1 is a synoptic diagram, and expression is by the structure of the fabric production system of one embodiment of the invention.
This system comprises that the decorative pattern that textile fabric designing apparatus 1, formation jacquard card are used forms device 3 and jacquard loom 5 automatically.The step that textile fabric designing apparatus 1 is finished comprises: the step of design textile decorative pattern on display device; Set up the step of detail of design, and the step of setting up the jacquard card data.Automatically pattern forming device 3 usefulness jacquard card data 2 are set up jacquard card 4.Jacquard loom 5 is read jacquard card 4, and produces fabric 6.
Textile fabric designing apparatus 1 is a graphic computer, and it comprises main frame 11, keyboard 12, display device 13, colored video scanner 14, mouse 15, digitizer 16 and external storage device 17.
Fig. 2 is a functional-block diagram, represents the major part of the textile fabric designing apparatus 1 in this system.Textile fabric designing apparatus 1 comprises color image scanner 14, video memory 22, and image editing/processing section 21.First pictorial data that video memory 22 memory scanning instrument 14 are read.First pictorial data that 21 pairs of image editing/processing sections are stored in the video memory 22 is edited/is handled.The dark compression process of first pictorial data is mainly finished in image editing/processing section 21, to form second pictorial data.Textile fabric designing apparatus 1 also comprises image conversion/processing section 23.The image that the 23 pairs of colors in image conversion/processing section concentrate amplifies or dwindles, and the gained image conversion is become the used fabric image (detail of design) of automatic pattern forming device 3.Image conversion/processing section 23 comprises that outline line extracts part 24, vector conversion portion 25, phasor coordinate conversion portion 26, outline line drafting part 27, and fills processing section 28.
Then, each part of this system will be described in detail.
Fig. 3 is a process flow diagram, and expression is read the step of pattern original copy from color image scanner 14, to the treatment scheme of the color correction step of reading pictorial data.The pattern original copy that the designer draws comprises multicolour pattern.Color image scanner 14 reads the pattern original copy, is stored in (step S1) in the video memory 22 with the raster data form as first pictorial data.According to the drawing command from sending into such as input medias such as keyboard 12, mouse 15 or digitizers 16, first pictorial data that image editing/processing section 21 will be stored in the video memory 22 is presented on the display device 13.Then, 21 pairs first pictorial data of image editing/treating apparatus are carried out color concentrated (step 2 is to 4).In this, the size that is presented at first pictorial data on the display 13 can change, and makes designer's design textile effectively.
Why needing that first pictorial data is carried out color and concentrate, is because the used number of color of jacquard loom is limited in 16 to 2 kinds of colors.Suppose each R, G, B (red, green, orchid) image point has 256 kinds of tones, and then the number of color of scanner 14 first pictorial data of reading will reach 16,780,000.With these dark being reduced on the specified multiple representative color of designer.At first, the designer specifies the representative color of first pictorial data, and their representatives are presented at the color (step S2) of the various piece of the indications such as the first pictorial data cursor on the display.Representative color can be specified automatically by the statistic processes that first pictorial data is carried out.But in this embodiment, representative color is manual the selection, is concentrated into background colour with the color that prevents some zonules.For example, red little garden is important in Fabric Design under the blue look background.Therefore, when needing, display screen can be amplified, use up to be marked on and specify the color part that is designated as representative color on the display device.
Then, with the color of first each part of pictorial data, replace to one by one and the immediate a kind of representative color of this actual color (step S3) image point.In fact, as what explain with RGB three dimensions shown in Figure 4, dark compression process is by calculating each R of each image point, G, each R of B value and representative color, G, B value Ri, Gi, the deviation between the Bi (wherein i=1 to n) or finish apart from di.This is represented with following formula apart from di.
di＝(Ri-R)
2+(Gi-G)
2+(Bi-B)
2 ....(1)
Calculate the misalignment di between each and each representative color (i=1 to n) in all image points.According to this result of calculation, so that di becomes minimum mode, all image points are replaced to representative color, obtain grating with this
DataSecond pictorial data of the use representative color of form.
Second pictorial data that limits through color is carried out (step S4) color correction process.The color correction process have been carried out data that color concentrates improperly and is carried out smoothing and finish in order to make.In fact, the window that on display, shows a preliminary dimension.Move this window, make it to comprise the position of an incorrect color.The color correction process is filled this window with a kind of representative color and is finished.For example, as the result of dark compression process, as shown in Figure 5, in regional A, may form the point b that its color is different from regional A and B.For the color that will put b replaces to the color of regional A, big window W is being arranged to comprise under the situation of a b and regional A and B, the color of inhibition zone B makes it and can not change.Then, all colours of window W is corrected into the color of regional A.
Carried out second pictorial data of color correction, be stored in the video memory 22 with the raster data form.The resolution that is stored in second pictorial data in the video memory 22 generally is lower than the density of actual fabric warp thread and weft yarn.
Therefore, image conversion/processing section 23 second pictorial data that resolution is low converts the fabric image data suitable with fabric threads density to.
Fig. 6 is a process flow diagram, the process of presentation image conversion/processing section 23.At first, divide 24 from the outline line extraction unit.Outline line extracts the cross-sectional data (step S11) that part 24 begins to follow the tracks of image.The tracing process of cross-sectional data is finished by step shown in Figure 7.Second pictorial data that is presented on the display device 13 is carried out raster scanning, to determine the number of colours (step S21) of second pictorial data.Then, select wherein a kind of color, follow the tracks of its outline line, to obtain position vector (step S22).All colors are finished tracing process (step S23).
As a kind of decorative pattern tracking of color, for example, as shown in Figure 8, suppose to have pre-determined starting point Po the border of counterclockwise following the tracks of decorative pattern.When tracing into starting point Po once more, promptly accuse for this decorative pattern tracing process and to finish.The data that obtain with such tracking are called first cross-sectional data.First round profile data comprise the coordinate of colouring information, starting point Po, and one group of data such as information of adjacent image point.Specifically, the information of adjacent image point can be expressed as 8 to one of (eight-way) vector.A byte can be expressed the information of two points.Like this, the memory capacity with very little promptly can store first cross-sectional data that comprises pattern original copy information by the raster data form fully.
First cross-sectional data converts vector data series (step S12) to vector conversion portion 25.Like this, every outline line is all used one group of absolute coordinates value representation, obtains second cross-sectional data of vector data form with this.
After this, each phasor coordinate in 26 pairs second cross-sectional datas of phasor coordinate conversion portion is changed, and obtains third round profile data (step S13) with this.Represent the parameter of warp thread spacing, weft count or the like for 26 inputs of phasor coordinate conversion portion.Phasor coordinate conversion portion 26 is carried out the coordinate conversion process according to these manufacturing parameters, and the display resolution of pattern original copy is represented with following formula (2).
(x y) is still non-switched phasor coordinate in the formula; (X, Y) be the conversion after phasor coordinate; And [A] is transition matrix.Transition matrix [A] is arranged to the ratio of the ratio of the second pictorial data level point density and warp count and the second pictorial data vertical point density and weft count.For transition matrix [A], except the fabric ratio, it is also conceivable that position translation amount, rotation amount or the like.
Figure 10 represents to amplify by the phasor coordinate transfer process example of 1.5 times third round profile data.
Then, outline line is drawn part 27 third round profile data-switching is become raster data, and deposits raster data in video memory 22 (step S14).In this case, the point adjacent with the bundle of lines couples together, and these points can be calculated with interpolation method.Like this, the outline line of versicolor decorative pattern reverts to the raster data of the dot density corresponding with warp thread and weft count.
Draw in video memory 22 after the outline line, outline line is filled (step S15) by the color corresponding to its colouring information.Fill 28 pairs of video memories in processing section 22 and carry out raster scanning, detect outline line, and determine its content.
Like this, second pictorial data of raster format promptly can suitable dot density converts the 3rd pictorial data of raster format to.Woven fabric tissues such as appointment such as plain cloth or lattice fabric for example, as shown in figure 11, are determined the relation of warp thread and weft yarn.Like this, just, obtain the jacquard card data 2 (that is fabric image data) of automatic pattern forming device 3 usefulness.
In this embodiment, use according to jacquard card data 2 and set up jacquard card 4, and the system of control jacquard loom 5 is as illustration.But the present invention also can be applied to have the system with the controller of jacquard card data 2 control jacquard looms 5.
Although shown and described the present invention with regard to its most preferred embodiment, but, for the professional and technical personnel, obviously, under the situation that does not break away from the spirit and scope of the present invention, can make above-mentioned and various other change, omission and interpolations in the form and details.
