Description
Technical field
The invention belongs to textile fabric design and production fields, and in particular to a kind of color-woven fabric design life of fast reaction
Production method.
Background technique
Yarn dyed fabric is to carry out woven fabric using dyed yarn, and yarn dyed fabric does not need to carry out again in postfinishing process
Dyeing or printing technology, the color and flower pattern of yarn dyed fabric can be used as the main feature for distinguishing different fabrics yarn dyed fabric, yarn dyed fabric
Color characteristic by the type of the yarn for weaving yarn dyed fabric, the ratio of each color yarn and arranging density of yarn etc.
The influence of many factors, the color characteristic between color-woven fabric similar in color are often difficult to accurately distinguish.The flower pattern one of yarn dyed fabric
As be grid flower pattern or strip flower pattern, the otherness of flower pattern is also not very big sometimes between different fabrics, only from flower pattern also very
Hardly possible is distinguished.The design and production procedure of traditional color-woven fabric include: that dyed yarn sets up meter, laboratory dyeing, looming weaving, later period
Sample cloth arranges, product inspection and finally sends out sample.It knits industry with coloring gradually to develop, design and production of the people for color-woven fabric
The requirement of speed increasingly improve, color-woven fabric generally requires to complete within one week from starting to be designed into final hair sample, tradition
The design producing method of color-woven fabric be extremely difficult to require, often there is the problems such as production cycle is long and design cost is high.
Therefore, simplify and fabric development cost is greatly decreased, improve the speed of product development, constantly shorten the development cycle, by fabric
It designs and produces and realizes that scientific and high efficiency is particularly critical.
In these cases, people start introduce computer be measured the sophisticated equipments such as color and fabric design, for weaving
The retrieval technique of fabric main feature also increasingly attracts much attention.Existing color or shape based on textile fabric
Image retrieval technologies, the color feature value, shape feature value, spatial position for typically extracting retrieval image and contrast images are special
Sign or a few persons combine, and carry out similarity calculation, then to achieve the purpose that image retrieval.Such as patent CN104462481 is public
A kind of synthetic image search method based on color and shape has been opened, extract retrieval image respectively and has compared the color characteristic of image
Value and edge shape characteristic value carry out similarity calculation, and using the average value of the two as between retrieval image and contrast images
Similarity final value；Patent CN102184250 discloses a kind of garment fabric sample retrieving method based on colored image matching, adopts
With the color of color image, intensity profile and the matched method of spatial position multiple features, fabric characteristics of image and fabric will be inputted
Reference sample characteristics of image in database carries out the matching analysis.Although the above method can save color surface of second order to a certain extent
The design of material and production time, but just not considering the features such as flower pattern and the institutional framework of color-woven fabric when building library, into
When row characteristic matching and similarity calculation, generally require to traverse full library, it is time-consuming still larger.
Therefore, study that a kind of speed is fast, high-efficient and high accuracy fast reaction color-woven fabric design producing method
It has a very important significance.
Summary of the invention
The purpose of the invention is to overcome above-mentioned problems of the prior art, it is fast, high-efficient to provide a kind of speed
The color-woven fabric design producing method of high fast reaction with accuracy.
In order to achieve the above object, the technical solution adopted by the present invention are as follows:
A kind of color-woven fabric design producing method of fast reaction, steps are as follows:
(1) classification is carried out by flower pattern and institutional framework after acquisition fabric image establish fabric image database；Acquire fabric
It is shot when image using CCD camera, acquisition environment is seal case, CIE standard illuminants D65 or CIE standard illuminants A
(color measuring, calculating and the light source of evaluation to be used for specified in standard GB/T3978-2008 " standard illuminants and geometrical condition "
For D65 and A light source), wherein the angle of D65 light source directive parabolic mirror is 20 ° -30 °, A light source directive parabolic reflector
The angle of mirror is 30 ° -45 °；
When illumination is mapped to body surface, can generate three kinds of situations: reflected light, transmitted light and part light are absorbed by object
And it is converted into heat.The reflected light and transmitted light of body surface determine the color that object is presented, it is therefore necessary to determine object
The color of material and environment light source.Color-woven fabric is opaque article, without the concern for the transmitted light face that therefore its surface is presented
Color base is originally reflected by it light decision.Reflected light is made of three components: Ambient, diffusing reflection and mirror-reflection.Wherein environment
Reflection is that incident light is unevenly incident on body surface from ambient enviroment and unequally reflects to all directions, diffusing reflection point
Amount and specular component indicate that specific light source irradiates the reflected light generated on a surface of an.We will avoid this excessively uneven
Environment light, therefore acquire color-woven fabric image when selection in the cabinet of sealing.Then specific light source preferentially selects CIE D65
Light source, D65 correlated color temperature of light source are that the relative spectral power distributions of 6500K and real daylight are closer, and light source is closest to consecutive days
Other apparent tones of light effect, hardly band, can preferably reflect the true colors of object, therefore when acquiring fabric picture
Optimal selection is D65 light source.But some customer requirements use A light source, A light source be correlated colour temperature be 2856K it is photochromic it is white in
Band point is yellow, but since its colour temperature is low, and the penetration power ratio D65 light source of light is strong (brighter).
Final fabric surface reflection light model can be expressed as I=kcIc+krIr+kfIf, wherein kc、kr、kfRespectively environment
Reflection, diffusing reflection, ratio shared by three components of mirror-reflection, Ic、Ir、IfRespectively Ambient component, diffusing reflection component,
Specular components, Ir=Ipd× cosi, If=Ips×cosnθ, IpdThe brightness of reflected light, i are when for light source vertical incidence
The incidence angle of light source, IpsFor the mirror-reflection brightness on mirror-reflection direction, θ is the folder in mirror-reflection direction and direction of visual lines
Angle, n are the convergence index of specular light.
For color measuring, calculating according to specified in standard GB/T3978-2008 " standard illuminants and geometrical condition "
Have with the geometrical condition in evaluation about reflection: di:8 ° of (diffusion: 8 ° include specular component), de:8 ° of (diffusion: 8 ° of exclusion mirror surfaces
Ingredient), 45 ° a:0 ° (45 ° of annulus/vertical), 45 ° x:0 ° (45 ° of one directions/vertical), d:0 ° (not including mirror-reflection strictly)
Deng, and opposite with above-mentioned principle same optical path 8 °: di, 8 °: de, 0 °: 45 ° a, 0 °: 45 ° x, 0 °: d etc..
In general, color analysis needs uniform diffusion illumination, bright mirror-reflection is avoided, according to standard, with two
D65/A illuminator is pointed into sample for 45 ° in sample two sides, and this lighting method eliminates the mirror of smooth or curved sample surfaces
Face reflection, highlights the beam-shaping effect of sample, is more suitable for lacklustre material.But fabric is a kind of between height diffusion and bloom
Material between pool, the image only generated by diffused light is very coarse, without surface texture, is not suitable for carrying out visual analysis.And root
According to di:8 ° of standard (diffusion: 8 ° include specular component): although this geometrical condition contains mirror-reflection but is not reduced very
The ratio of mostly irreflexive ingredient, so that cloth textured structure is unintelligible.Therefore ideal irradiating angle should between 8 ° -45 °,
This patent introduces gloss (because according to above-mentioned mould by the directional lighting and introduction parabolic mirror of different angle (8 ° -45 °)
Type formula knows I with the increase I of incidence angler、IfReduce, the texture of shooting can be unintelligible, so needing to increase luminous intensity), from
Three shade, coloured light, texture aspects carry out the characteristic effect that Comprehensive Evaluation considers sample, and the final result is D65
The angle of light source directive parabolic mirror is that 20 ° -30 ° of irradiating angle effect is best；A light source directive is to parabolic mirror
Angle be 30 ° -45 ° irradiating angle effect preferably (the beam intensity ratio D65 of A light source is strong, when 20 ° -30 °, Ir、IfIt is larger, phase
The received light intensity of machine is too strong, and shooting effect is poor, therefore angle should be greater than 30 °).
It is not only available clearly cloth textured and due to making to the reduction that lens aperture reflects under best shooting angle
Collected color is obtained compared to there is only diffusion illuminations better precision (reducing the standard deviation of L* and b* significantly), is made
The actual look of image and fabric is very close.And when shooting angle is less than 20 ° or is greater than 45 °, it is clapped under this shooting angle
The texture effect for the fabric taken the photograph and practical texture difference on effect are larger, and the fabric color of shooting and color difference in kind are larger
It is unsatisfactory for the requirement of Δ E < 1, is unfavorable for the fabric that portions of client directly selects in fabric Image Database in this way and modifies or produce,
