Background technology

The tissue of tradition picture-weaving in silk design is laid, and is first by ready-made, to organize the actual sample of knitting to arrange by color sequences, during woven design, by designer's Comparing patterns and tissue sample color, determines the correspondence tissue of this pattern color.Tradition Brocade Weaving card processed is very long with the phase, difficulty is very large, dull coloring, monochromatic one-tenth piece, waste time and energy, and man's activity is large, and the color contrast relation of selected each tissue is difficult to accurately show the change color relation of pattern.Face especially the exquisiteness of people to artwork performance, abundantly have a more and more higher requirement, classic method meet in product demand more and more difficult.

For the limitation of traditional design method, in colleague, started to do at present and attempted improving, the R&D Approach in this field mainly can divide two classes at present:

A kind of take Zhejiang University's longitude and latitude as representative, its mode is to carry out cat scanner with the sample of knitting of ready-made tissue, by scan image analyzing and processing, obtains the digital color value (as rgb value) of this tissue color, and institute processes through this in a organized way, can form a set of look storehouse of organizing.During woven design, by the digital color value of contrast patterns color and tissue color in computer, calculate the two difference and compare, be just easy to find out the tissue that approaches pattern color most from tissue bank.

Another kind is to change mainly for satin weave the research and development of doing.First it count certain class satin weave to divide equally by variation, obtains the theoretical color value of each change point.As certain 12 pieces of satin, warp adopts white, with single red parallel, does 1-2-3.....-12 point variation, and its rgb value can be 255,255, and 255 to 255,0, directly by 12 sections, divide equally, obtain the RGB theoretical value of each change point for 0.During actual design pattern Processing, first definite this pattern is weaved parallel color used, as adopt red, yellow, blue, black four, then adopt professional software that image is split as to red, yellow, blue, black four monochromatic patterns, similar printing color separation principle, four achromatic sheets all overlap, and original image can be showed completely again.With the theoretical color value of gained above, respectively each achromatic sheet is determined and organized and generate line version.Finally, by a synthetic four independent line versions stria terminalis version, just realized the design of this image.

The above-mentioned method of setting up color libraries with tissue scanning, must all knit sample as prerequisite to organize, large-scale bust brocade is weaved, during design, need easily thousands of look storehouse colors to quantity up to ten thousand for choosing, with the method, setting up look storehouse wastes time and energy, and cost is high, and produces while weaving and must keep and the identical colo(u)r streak of sample tissue and process conditions, once because the reasons such as colo(u)r streak dyeing replacing change, will there is deviation in the look storehouse of organizing used.

The another kind of method of doing color separation amalgamation that changes with satin weave, due to institutional framework restriction, the tissue that can utilize and the scope of application are also quite limited.

Embodiment

Below by embodiment, the present invention is specifically described; the present embodiment is only for being further detailed the present invention; but can not be interpreted as limiting the scope of the invention, some nonessential improvement that those skilled in the art makes according to the content of the invention described above and adjustment also belong to the scope of protection of the invention.

The establishment of picture-weaving in silk color tissue bank

The present invention take four through three latitude Sichuan brocade weaving technologies as example.

One, determine four silk thread color and thread counts through three latitudes.

According to weaving process and performance accuracy requirement; take built loom as basis; set the thread count that designed tissue is used; so-called weaving process and performance precision refer to the image definition requirement of weaving Sichuan brocade; conventionally also relevant with loom characteristic; under the condition allowing, better to show precision as best.The present invention determines that thread count is respectively, through close: 120, filling density: 60, warp fiber number: 75D, parallel fiber number: 75D.Look through put in order for: 1. red, 2. green, 3. yellow, 4. blue; Parallel put in order into: 1. black, 2. in vain, 3. white.

Two,, according to the institutional framework of longitude and latitude silk thread and color alignment, set up color mathematical model.

Institutional framework as shown in Figure 4, determine that surface layer silk thread color is respectively: warp X1 is red; Warp X2, indigo plant; Parallel YA is black; Parallel YB is white.In this structure, other silk thread of all kinds is interwoven in bottom, does not find expression in schematic diagram.In Fig. 3, X1, X2 represent respectively left and right two warps, and φ 1, φ 2 represent that respectively two through line width, and L1, L2 represent that respectively two through line length; YA, YB represent respectively two parallels, and φ a, φ b represent respectively two parallel width, and La, Lb represent respectively two parallel length.

First, determine the square measure of sample analysis.The principle of the square measure of getting, the surface layer structure of the complete embodiment tissue of palpus forms, and should adopt the integral multiple of its structure circulation is unit.According to actual warp and weft arranging density, first determine period.This example through close be 120 pieces/centimetre (every centimetre of warp numbers 120), 60 pieces/centimetre of filling densities.By above fixed four looks through three barry dyeings through bright and beautiful structure type, can learn every centimetre of warp and weft radical of all kinds of its surface layer, warp is 120/4=30 root; Parallel 60/3=20 root.Consider that now warp and weft is arranged closely, getting 1mm × 1mm is square measure, can obtain the orthograph of unit area surface layer model as shown in Figure 4, and surface layer consists of look warp X1, X2 and barry dyeing line YA, YB.

Shown in Fig. 4, portion while simulating its blend color with area occupied of all kinds, can obtain wherein total area Ar, warp X1 area S1, warp X2 area S1, parallel YA area Sa, parallel YB area Sb.The color rgb value of each silk thread, as R1, G1, B1 can be expressed as R, G, the B value of warp X1; Ra, Ga, Ba can be expressed as R, G, the B value of parallel YA, and other is analogized.In calculating formula, the object of each symbol representative is referring to Fig. 3.

Represent the matrix Es of each blend color share, the matrix Ec of each color rgb value is as follows:

Es=(S1,S2,Sa,Sb)

By Fig. 4, can obtain each variable-value:

S1=φ1×L1×6=(1/6)×(1/4)×6=0.25

S2=φ2×L2×6=(1/6)×(1/4)×6=0.25

Sa=φa×La×6=(1/4)×(1/6)×6=0.25

Sb=φb×Lb×6=(1/4)×(1/6)×6=0.25

Es=(0.25,0.25,0.25,0.25)

$\mathrm{Ec}=\left|\begin{array}{ccc}R1& G1& B1\\ R2& G2& B2\\ \mathrm{Ra}& \mathrm{Ga}& \mathrm{Ba}\\ \mathrm{Rb}& \mathrm{Gb}& \mathrm{Bb}\end{array}\right|$

Total area Ar can think herein:

Ar=1 × 1=1 or $\mathrm{Ar}=\underset{i=1}{\overset{4}{\mathrm{\&Sigma;}}}\mathrm{Es}\left(i\right)=1$

According to blend of colors theoretical foundation, can simulate the color RGB theoretical value of each colo(u)r streak herein:

$\mathrm{Ec}=\left|\begin{array}{ccc}255& 0& 0\\ 0& 0& 255\\ 0& 0& 0\\ 255& 255& 255\end{array}\right|$

If: λ=1/Ar E=EsEc is

λE=1/1×(127.5,63.75,127.5)=(127.5,63.75,127.5)

Each number rounds off and rounds, and the theoretical RGB colour that gets final product get Ci organized whole is:

R?128?G?64?B?128

With mathematical expression variable above the substitution of different colo(u)r streak color value, can obtain the organized color RGB theoretical value of this structural series.

For the color color of the color mixture of longitude and latitude silk thread, its essence is mixed stack look.It finally can be summarized as to the mixing stack of coloured light primary colors " red, green, blue " (R, G, B).If it is carried out to color value simulation with numeral, multiple look A1 in theory, A2, A3 ... the blend color value of An, can according to of all kinds in stack portion M1, M2, M3 ... Mn, obtains R, the G of its color mixture, the theoretical value of B is:

R=(RA1×M1+RA2×M2+RA3×M3+……+RAn×Mn)/(M1+M2+M3+……+Mn)

Be more than the calculating of red (R) value, other G, B value are calculated in like manner.Wherein, " R " is the mixing resultant value of red (R), and " RA1 " is the R value of color A1, and " M1 " is color A1 portion in entirety is mixed, and other is analogized.

Through the tissue of weft fabric, in a lot of situations, can be divided into the double-layer structure of surface layer and bottom.Generally, the expression of its tissue color, is mainly determined by the silk thread blend color of surface layer, in the situation that surface layer silk thread density is very large, can ignore the impact of bottom silk thread color.Based on establishing color mixture theory above, can specifically determine organize look calculate theoretical model as depicted in figs. 1 and 2: Fig. 1 surface layer silk thread structural representation, Fig. 2 surface layer silk thread orthograph.

The structural representation of the plain weave surface layer that as shown in the figure, in figure, look is made into through X1, X2 and barry dyeing YA, YB.As shown in Figure 1, the color of its fabric tissue general performance should consist of several some factors: shade J and the reflection at the solid colour of light source colour, warp X1, X2, the solid colour of parallel YA, YB, space K color and longitude and latitude overlapped place.Because the sensitive surface of space K bottom itself is little and very faint, what therefore shadow region was accepted is reflective, substantially by true qualities and the light source of surface layer silk thread, is determined.To sum up, in reality, when calculating simulate fabric organized whole true qualities, can take the area dividing method with its frontal plane of projection, add up each silk thread color portion in entirety is mixed.The present invention can be reduced to Fig. 3 by the model of Fig. 2.Fig. 3 is the simplified structure signal of surface layer colo(u)r streak orthograph.

In Fig. 3 orthograph, the true qualities of warp X1 area occupied in synthetic is: φ 1 × L1, and wherein φ 1 is the width of warp 1 cross section projection, L1 is the length that warp 1 exposes.Other is analogized.

Determine that surface layer silk thread color is respectively: warp X1 is red; Warp X2, indigo plant; Parallel YA is black; Parallel YB is white.In this structure, other silk thread of all kinds is interwoven in bottom, does not find expression in schematic diagram.In Fig. 3, X1, X2 represent respectively left and right two warps, and φ 1, φ 2 represent that respectively two through line width, and L1, L2 represent that respectively two through line length; YA, YB represent respectively two parallels, and φ a, φ b represent respectively two parallel width, and La, Lb represent respectively two parallel length.

Three, the correspondence tissue of every kind of silk thread structure and color alignment is carried out to numeral name.

Take four colour developing of the one through three latitude tissues types as example, according to the each warp of unit area, appear the quantity of counting herein, be divided into 1-26 level colour developing transition.And according to set thread count, set and organize the surface layer warp and weft quantity being risen all in 2.For example: warp is the red 1. serial transition tissue of black formation of parallel that adds 1.; Warp is the red 1. serial transition tissue of black 2. white formation of parallel that adds 1.; Warp is the red 2. green 1. serial transition tissue of black formation of parallel that adds 1.; Warp is the red 2. green 1. serial transition tissue of black 2. white formation of parallel that adds 1., etc.

Card Design of the present invention adopts Zhejiang University's longitude and latitude specialty fabric pattern design software, and its desired standard organization name must be 8 character strings with interior numeral and character composition, and first place must the beginning take letter " P " as symbol.Again for ease of with other serial tissue division, this types of tissue institute standard organization name second is unified with character " N ", all the other 6 tab characters as the each tissue of this series.Wherein, each warp and weft is denoted as following table 1 successively by symbol:

After each parallel tag, one-bit digital indicates the floating long progression of warp, as organization name: " PN1A0 ", " P " is regulation symbol, and " N " unifies tag for this types of tissue, and " 1 " representative color is through red line, " A " represents parallel black line, " 1A " represents that red warp " 1 " and black parallel " A " interweave at surface layer, and " 0 " is illustrated in the 1-26 level colour developing transition of warp, and the grade of demonstration quantity is the 1st grade, and (numeral is larger, represent warp show count more), by that analogy.

This programme warp comprises 1-26 level colour developing transition, only with unit numbers 0-9, can not express completely, at this, with the variation of the corresponding parallel symbol before this numeral, expresses the difference of colour developing transition grade on tens.The for example tissue " PN1A0 " of precedent, if this organizes warp, colour developing is the 11st grade, this tissue is by name: " PN1D0 ".Following table 2 is respectively the each parallel tag of corresponding warp in each tens colour developing grade respectively: table 2

?	Individual position	Ten	20
				Black	A	D	G
White 1	B	E	H
				White 2	C	F	I

Get arbitrary tissue " PN1A34H1 ", from aforementioned naming rule, this tissue is interweaved at surface layer with parallel black " A ", white " B " by warp red " 1 ", blue " 4 ", and all the other warp and weft are hidden.Red " 1 " interweaves at surface layer with the 4th grade of colour developing transition structure with black " A ", and red " 1 " is covered by parallel white " B "; Blue " 4 ", with white " B " to interweave at surface layer with the 22nd grade of colour developing transition structure, blue " 4 " are covered by parallel black " A ".

Four, by the calculated with mathematical model color value (being rgb value) of numeral name tissue.

From getting altogether the color value of 10 tissues between different chromatic zoneses, its calculated value and the actual scintigram color value of knitting sample, be converted to H, S, V(form and aspect, purity, lightness) value list is compared as follows table 1:

Color rgb value conversion HSV value formula is as follows:

$s=\left\{\begin{array}{cc}0,& \mathrm{if}\max =0\\ \frac{\max -\min }{\max }=1-\frac{\min }{\max },& \mathrm{otherwise}\end{array}\right.$

υ＝max

In above formula, max, min represent respectively the minimum and maximum value in rgb value three.

Fig. 6 and Fig. 7 explanation: in figure, block curve is the theoretical color value numerical value line that calculates, and dashed curve is scanning color value numerical value line, and the coordinate longitudinal axis is S or V value, and transverse axis is for organizing sequence number.

By H value comparison sheet, theory and scanning color H difference are in ± 1, and theoretical calculating color and fabric scanning look form and aspect are very identical.Because scanner has the impacts such as strengthening or weakens to scan image lightness and purity, therefore in coordinate system, observe serial color S, V value change curve, from Fig. 6 and Fig. 7, S, V value change curve form are consistent, and it is consistent that purity, the lightness that its serial color is described changes contrast rule.The theoretical color value of fabric tissue and the color of knitting sample scanning have high consistency.

Five, by silk thread and color alignment combination, obtain a large amount of different tissues, calculate its corresponding color value (being R G B value).Create band color value tissue bank, i.e. color tissue bank, selects look for design.

As Part III, describe the organization type title series of setting up, get equally tissue " PN1A34H1 ", this organizes red " 1 " and black " A " to interweave at surface layer with the PWJ3 of transition structure shown in Fig. 8, and red " 1 " is covered by parallel white " B "; Blue " 4 " interweave at surface layer with the PWJ21 of transition structure shown in Fig. 9 with white " B ", and blue " 4 " are covered by parallel black " A ".

According to Part I, describe set weft density and aligning method, every 1mm × 1mm areal extent, comprises warp and weft quantity and is: 12 of warps, 6, parallel.Its middle longitude take 1. red, 2. green, 3. yellow, 4. indigo plant is as one group, comprising group number is 12 ÷ 4=3 groups; Parallel with 1. black, 2. in vain, 3. Bai Weiyi group, comprising group number is 6 ÷ 3=2 groups.
