For make basic organization segment fill time can with the color coordination of yarn, thereby the fabric outward appearance of the sample of performance design more really, in step (1), obtain basic organization segment and carry out gray processing processing cutting, basic organization segment is converted into gray scale and organizes segment.Further, in the present invention, also image gray processing corresponding each fabric tissue is treated to middle gray level image.
For with reference to sample, the specification of inhomogeneity yarn is different with color.For each fabric tissue, in the present invention, each class yarn, to there being a yarn coverage diagram, has been realized the operation of only need once painting of same class yarn, has greatly improved formation efficiency.In the time of practical operation, but each class yarn is numbered, and is convenient to subsequent operation.And in order to superpose in the time filling, in step (2), organize the overlay area of each class yarn in segment and background area (gray scale is organized the part except such yarn overlay area in segment) to make a distinction gray scale by binaryzation.In the present invention, making the color of overlay area when binaryzation is black, and background area is white (vice versa).
In the yarn distribution map generalization method of shuttle-woven fabric of the present invention directly using the fabric tissue of existing fabric (with reference to sample) as elementary cell, analyze the overlay area of each the class yarn in each fabric unit, utilize the overlay area of each the class yarn in each fabric tissue to go to corresponding region in filling design sample, finally respectively to each class yarn designated color, the yarn distribution map that generates design sample, has improved design efficiency greatly.The more important thing is, generation method of the present invention does not need fabric specialized technical knowledge substantially, reduce the technical threshold that fabric turns over sample and design work, and improved operation smoothness, convenience, solved traditional textile enterprise to a great problem existing in high technology content enterprise transformation process.
Design sample is generally the design of design, first according to existing border in design, design sample is divided into several regions, but while division, be not limited to existing border, can suitably adjust as required or segment, then be each Region specification color and fabric tissue according to design idea, wherein, color can be specified arbitrarily (the original color that also can be appointed as this region in design sample), and fabric tissue is necessary for reference to the one in sample fabric tissue.
For the complete cycle that ensures that fabric tissue can continue in all directions, described elementary organization's segment is rectangle.
Described step (1) also comprises that the gray scale to obtaining organizes segment to carry out gray correction.
Gray correction can adopt histogram equalization, greyscale transformation, and homomorphic filtering, the methods such as Gamma rectification realize.When the image obtaining with reference to sample has effectively been eliminated in gray correction because the reason such as illumination and shooting angle causes the problem inhomogeneous with reference to the image illumination of sample, and can also the impact of the original yarn color of calibration reference sample on gray-scale map brightness, avoid former figure (elementary organization's segment) brightness too bright or that too shadow rings the yarn distribution map obtaining after stack colouring.

In described step (3), the color of zones of different is all not identical with the kind of fabric tissue.
By the kind zoning of color and fabric tissue, can once complete like this colouring of same class yarn, compared with the method for separately each one thread being painted, greatly reduce workload.
In described step (3), utilize regional in index color mark design sample.
Carry out mark by index color, be conducive to save memory space, make the sharpness of border of adjacent area, be convenient to carry out region operation in subsequent processes, the color replacement in such as whole region etc.
As preferably, while filling in described step (4), first utilize the gray scale that current region is corresponding to organize segment to fill, recycling and gray scale are organized yarn coverage diagram that segment the is corresponding current region that is added to.After filling, also can excise as required the part outside current region border.
When filling, directly corresponding gray scale is organized segment (gray scale of fabric tissue corresponding to this region is organized segment) tile behind whole region (when tiling between adjacent segment mutually continuously continuously every, and zero lap mutually), then each class yarn coverage diagram is expired to whole region according to identical rule tiling.Also can first select arbitrarily a position as original position, and organize segment to be filled to this original position gray scale, successively corresponding yarn coverage diagram is superimposed to gray scale afterwards and organizes on segment, and then obtain the filling segment of current region, and directly with this filling segment whole region of tiling.
In the present invention, in order to present Overlay, described yarn coverage diagram can arrange certain transparency, and it is 30～70% that transparency for example can be set.
When stack, organize segment to be placed in bottom gray scale, the light and shade that can better show on each one thread changes, increase the fabric appearance details of yarn distribution map, make the yarn distribution map finally obtaining there is the appearance tactile impression of yarn, improved the precision of yarn distribution map, if only use yarn coverage diagram, the yarn distribution map obtaining after yarn colouring lacks texture, and precision is not high.
