Abstract

A manufacturing method for broche weft exhibiting multiple gray level images, which is used to weave the broche weft with multiple gray levels. The present invention is to construct a series of innovative unit-gray-level pattern with gray levels, and further incorporate an innovative lower pattern method, i.e. residual method, which is to obtain a broche pattern of an image on a weft according to the gray level of the digital image and employing the unit gray level pattern. Because these unit gray level patterns are formed with the concept of digital encoding, which goes beyond the conventional basic pattern having limitation on the arrangement rule of the pattern points. These unit gray level patterns not only have the gray levels, and have the most variation levels for the gray levels. Moreover, the present method eliminates the possibility of warp width or weft width being too long in the patterns during designing the unit gray level patterns, so that the final weft pattern does not have the problem as the conventional technique for re-modifying the points, and can be directly weaved. Further, the established unit gray level pattern provides the repetitiveness and uniformity, so that these two characteristics can make the image exhibited by the weft patterns the clearest. The advantage of the residual method cannot only make the size of the weft image the same as that of the original image, but also obtain the best resolution with the least number of pattern points.

Description

507032 V. Description of the invention (1) "Technical Field of the Invention" The present invention is a method for manufacturing a jacquard fabric representing multi-grayscale images, and in particular, constructs an original unit grayscale organization chart. At the same time, it can also be used with the original remainder Method, one-to-one conversion of image points to the texture, to obtain the grayscale image graphics with the highest number of gray levels, with the same number of points and high resolution, and to solve the need to organize the organization chart due to the continuous warp and weft floating of the fabric Fix the problem. "Background of the invention"

Traditional weaving design methods usually require designers to draw artisan drawings. The actual operation is usually complicated and takes a long time. Therefore, jacquard weaving design software is used on the market for design. At present, the main design methods of weaving design software are Each color corresponds to a traditional texture, and then the organization chart is designed. The texture design using this method can show the outline of the image, but it cannot show the brightness or grayscale of the image, so the image It will be distorted, and often because the outline is not clear or the latitude and longitude float may be too long, it needs to be repaired, which is quite time-consuming.

Secondly, the related jacquard fabric manufacturing technology also uses the structure under the shadow satin to obtain a colored texture texture chart, but the gray level produced by the shadow satin is very few, like eight shadow satin has only 7 Gray level, it is difficult to express continuous gray level changes, and the technology must be repaired in order to avoid continuous warp and weft floating of the fabric, this work is not only lengthy and will destroy the gray level of pixels. In addition, the existing organization method cannot be used to balance the organization chart.

Page 5 507032 5. The points of the invention description (2) and the sharpness of the image; only a lot of organization chart that is twice the size of the original image can be used to obtain better image sharpness. This problem will limit the performance of the image Of choice. Regarding the traditional computer-aided software for weaving design, Wu Dehua once did the research and development of a woven production design system by selecting colored yarns and wearing healds. Chen Zhiqiang and others have also developed the weave design and cloth simulation system in the following ways. In addition, Lin Zhengzhong used the organizational algorithm to design the texture. The texture design of the above three articles is conceptually using the traditional texture, which has nothing to do with the performance of the gray scale of the present invention. As for the jacquard weave design software currently used on the market, we need to have expertise in fabric construction in order to carry out weave design. There are three main design methods: (a) the first method is for the designer to divide the color picture into several different areas, and then select various traditional weaving textures to fill the map in different areas; (b) the second way is to limit Each color in the color picture corresponds to a traditional texture, and the texture is designed. (c) The third method has fewer restrictions than the other two. The designer can choose the corresponding relationship between colors and traditional textures to design the organization chart. Weaving design using the above three methods can show the outline of the image, but it cannot show the brightness or gray level of the image, so the image will be distorted, and often because the outline is not clear or the longitude and latitude may be too long, it needs to be Repairs are time consuming in practice. Other related jacquard fabric manufacturing technologies, such as

Page 6 507032 V. Description of the invention (3)

No. 340880 "Manufacturing method of jacquard cloth with color image", there is also a colored woven structure chart obtained by using the shadow to transfer the tissue, but the gray level produced by the shadow satin is very small, and it is difficult to represent the continuous gray level change. Moreover, in the technology, it is mentioned that in order to avoid the long-term warp and weft floating of the fabric, the organization chart repair work must be performed, which is not only tedious but also destroys the gray level of the pixels. In addition, the manufacturing steps disclosed therein include a step of calculating the size to be enlarged or reduced, and a step of filling in the shaded satin with a traditional similar gray scale, respectively. Therefore, this method has the problem of distortion due to enlargement or reduction (not one-to-one point-to-point correspondence), which means that the appropriate resolution cannot be achieved with the same number of tissue points, and on the other hand, it has a traditional shadow satin texture. Disadvantage of too few gray levels when filling in. Therefore, it is necessary to develop new technologies to solve the above disadvantages. "Object of the invention"

The object of the present invention is to solve the problems faced by the jacquard weave design in the background description. The meticulously original 4x4, 5x5, 6x6, 7x7, and 8x8 unit gray level organization chart used in the present invention has up to 9, 16, 25, 36, 49 gray levels, which can produce continuous smooth gray levels that are not in the traditional way. Variety. In addition, the present invention proposes an innovative lower organization method _ remainder method, which is cleverly matched with the original unit gray level organization chart, and has the ability to keep the texture organization chart the same size as the original image (corresponding to one by one point by point), And can provide the best image resolution. Secondly, the invention excludes the possibility of warp or weft floating in the organization chart when designing the grayscale organization chart of the unit, so the final weave texture

Page 7 507032 V. Description of the invention (4) There is no unit gray scale characteristic that needs to be established in general. It can make the weave pattern to achieve the above purpose. Jacquard fabric manufacturing method. The gray scale organization chart is followed by digital coding. 4x4, 5x5 level weaving chart; each, each: The organization chart of the problem of the repair point is presented in the organization chart. In the present invention, the fabric is constructed on the fabric, and its structure is composed of 6x6, 7x7 units of gray scale (a). Same as before opening (b) With floating (c) Single-dispersion (d) With the same white silk, weaving directly. Moreover, the repeatability and uniformity are the clearest when using these two images. Provides a weaving of multi-level grayscale images. The image is composed of a unit grayscale organization chart of 'each group of grayscale organizations' in a number of units. 16' 25, 36 or 49 grayscale or 8x8 unit grids. Follow the following rules-gray ;;: Ding added another white tissue point, that is, a ^ hierarchy level, and each newly added white tissue point is not adjacent to the increased white tissue point, and the average dispersed group is early Each row and column in the grid is solid and one latitude float; the warp and weft floats in the grid are distributed as evenly as possible in the grid, and the first-order unit of each group in the gray-scale organization chart is, 4, 5, 6, 7, 8 white organization points that are not adjacent to each other and are evenly spaced apart; and a unit gray level organization chart with a set of different gray levels with a right tongue # " There are repetitiveness, among which the single gray level is followed by the single iron pseudo. The standing gray level is the same as the gray level unit gray level organization except the color organization points. "Yuezhi

Secondly, the "manufacturing method of jacquard fabric of the present invention that expresses multiple grayscale images" includes: In two pre-processing steps, an image or image is digitized and stored in 4 7 brains, of which the digitization is obtained first X times Y pixel original image to 9 or image 'and convert it to gray scale value (G) from 0 to 255, and then evenly distribute, 16, 25, 36, or 49 gray scale levels; one unit of gray scale Organization chart generation steps. Each group of unit gray scale organization charts uses the concept of digital coding to build a unit gray scale with a 9, 3, 4, 25, 36, or 49 level gray level followed by a 4x4, 5x5, 6x6, 7x7, or 8x8 unit grid. Organization chart; In addition, the gray-scale organization chart of each group of units follows the following rules when constructing: (a) same-level opening; (b) same-floating and (c) the same sub-divided units in the unit Adding a white tissue point in the grid one by one will increase the level ', and each newly added white tissue point is not adjacent to the previously added white tissue point, and is evenly dispersed.

Each row and each column in the unit grid of the group is fixed with a weft float; the warp and weft floats in the I grid are distributed as evenly as possible in the grid hundred, and the grayscale organization chart of the first-order unit of each group has 4, 5, 6, 7, 8 non-adjacent and flat white tissue points; and: knife units but different units of gray levels have repeatability, of which the next gray level is ordered by this level gray In addition to the first-level units of the gray level, in addition to the gray-level units, 1

507032 V. Description of the invention (6) I / The rest of the white tissue points are exactly the same; a post-processing step is to use the remainder method to obtain the weave texture chart, and the 5 number method is based on the coordinates of each pixel (x, y), divided by the number of one-sided grids 4, 5, 6, 7 or 8 of the unit fire P self-organized graph, respectively, to obtain the pairwise unitary number 8 ^, ^ of the pixel, and then converted according to the pixel Gray level, get one-by-one unit gray-level organization chart, and then move a single point of the position corresponding to the remainder a and ^^ to ..., or white, and move it to (X, y) of the texture organization chart, thereby , A pair: fill in the picture point by point to form a fabric with a multi-gray scale image weave texture.

[Detailed description of the invention] The method proposed in the present invention is a gray-scale group with more gray-level units? The figure shows the gray level of the original picture, so it has a more realistic effect. When constructing 5 :: Gray: organization, the continuous warp and weft floating length has been limited. Can be woven, in addition to the present; the proposed remainder method to organize, not only can maintain the size of the original image (because of one-to-one point-to-point correspondence), and g LV,, .. and get the highest image resolution with the fewest organizational points degree. For the gray group organization chart of the five groups of the present invention, please refer to the second section. A method for manufacturing a jacquard fabric applied to multi-gray images from Ding Jiu and J Bai Group is used. The kappa image on the fabric is composed of a plurality of units. The gray-scale organization chart is composed of digits. Each gray-scale organization chart uses the concept of digital coding to construct a 9, 3, 4, 25, 36, or 49-level gray level followed by 4x4, 5x5, 6x6, 7x7, or 8 to unit

Page 10 507032 V. Description of the invention (7) __ Grid unit gray scale organization chart; Also, the following rules are followed for each group of monostructure: Another level organization chart is under construction (a) A white organization is added to the unit grid one by one. The point is increased by one level, and each newly added white tissue point is not adjacent to the previously added white tissue point, and the average score is &ON; (b) = — each row and each One column is fixed with one warp float and one weft float; (c) $ = The warp and weft floats in the grid are distributed as evenly as possible in grid eight, where the first-order units of each group are in the gray-scale organization chart.

Examples are given and the steps are explained as follows: 1. Digitalization of the image The image or drawing to be designed (as shown in Annex I) (Color photo) scanned by the scanner and converted into a gray-scale black and white digital image (as shown in the third picture) 'stored in the computer. In order to improve the gray level of the texture organization chart, image processing software should be used as needed Increase the contrast of the healthy image. Finally, select a part of the image of appropriate size (referring to the area) as the texture design and use it. 2 Construct a grayscale unit grayscale organization chart. In order to use the texture to express the grayscale of the image points , You can choose the black warp

Page 12 Λ, Zanming Note (9) ^ and white weft are intertwined, that is, the warp floats a mile in color. In the selection-Danshi ^ Yue and Weifude-BaijieΪ :! 袼 袼 arrange different longitude and latitude floating organization, and form each: ί 2 is an early position grid of 1¾ degrees, this kind of ΝχΝ unit grid is called ^ different Gray chart, per-unit gray-level organization chart can be used to represent the 'post-fire-level organizational unit: sub-size selection, and gray-level-underlevel values must be considered. The weavability, the practical size should be between 4: 4 said ;, mesh and texture points. " The first picture created by 4 χ 4 to 8 X 8 organizations shows the use of 4 X 4 to 8 X 8 stars to construct five groups of gray-scale organizations 8 X8 early bitcoin compliance The following 4 rules: The construction of the two-early gray-scale organization chart is the same = successively increasing in the unit grid-the level, and each new white group is added; the color organization points are not adjacent, and the grid and grid are evenly dispersed Each of the rows and columns is fixed in the 'Warp: ΐ grid: the J floating point and latitude floating point of the 尽量 are distributed as evenly as possible on the grid, with the white color scattered in the order M and 5 = Weaving points; and 8 non-adjacent each other and average score (d) = ϋ but different gray level units gray level group 3 has repeatability, in which

It is the same as the pre-grey-level unit gray-scale organization chart except for the white organization point of the new J 507032 V. Invention Note (10); the first rule is derived from the concept of digital coding. Increasing a gray level, so the gray level value is continuous, and its change level is also 3 most. The second rule is the organization that fixes some organization points. First Figure 7 The white latitude floating point and the black warp floating point in the highest order organization chart of the same group of unit cells are fixed organization points, and each column and each row in the unit cell have a fixed organization point. Warp floating point and latitude floating point. The purpose of this restriction is to ensure that the maximum continuous warp and weft floating length in the fabric is less than the unit cell range. So using 4 X 4 to 8 X 8 unit grids, the maximum continuous floating length is 3, 4, 5, 6, and 7 tissue points, respectively. Because continuous floating is too long, it will cause loose fabric. To avoid this problem, a smaller unit grid must be used, but in this case, less gray levels will be obtained. Therefore, we should consider the actual needs of the fabric and weigh the effects of the two. Select the unit grid size. The third rule requires that the warp and weft floats be as uniform as possible to prevent the warp and weft floats from arranging to form a specific regionality or directionality, which causes the iron pattern of the textured group after the organization to have a clear background texture, which destroys the original image vision. The fourth rule is the repeatability of the unit gray scale organization chart. The purpose is to make the texture organization chart of the image clearer. The effect of the above rules on the weave texture will be further explained in the following description. The grayscale images mentioned above usually have gray levels ranging from 0 (black) to 25 5 (white), with a total of 256 gray levels, but the gray levels of the unit gray organization chart mentioned above are only 9 to 49, so according to the image The month of the organization under the gray scale must be divided into 2 to 6 gray levels first, and then the

\ JJZ V. Description of the invention (11) Use the aforementioned unit gray-scale organization chart to lower the cylinder _r, and weave to obtain the weave texture organization chart. 3. Weave texture organization chart based on the remainder method. In this description, three keys are provided ^ Yufu milk, soil i, and weaving method 'include the corresponding map filling method, the ten mean method of insult and the remainder method, but And the middle-is a conventional technique, just for analysis; ^ Corresponding to the mapping method and the neighborhood average method are bell |, Tu Yanbi 'is not the protection target of the present invention, σ negative remainder method is original. w, and if 8 × 8 unit gray scale fine green ^ ^ m ^ ^ is used as an example, we will explain and compare them separately. The corresponding mapping method is to sequentially take the gray value of each pixel in the shirt image, and then take the gray value of each pixel in the shirt image, and then sequentially compare it to the value of 8 ys 1. , ^ " The 8 8 early gray scale organization chart is filled in, considering that the length and width are the original shadow silly 8 Russ +-,, take. . The neighborhood averaging method ί::: · After calculating the gray level value of 8 x 8 pixels in the image, calculate the average second-order value 'and then select the corresponding 8 χ8 unit according to the average gray level value ^: group = graph' and Fill in the original image position, and perform the above steps in order. After t, weave a texture texture map of the same size as the original image. The former two are general image processing methods. The present invention proposes a new organization method-the remainder This method is to select the organization of the organization points according to the unit gray level organization chart corresponding to the gray level of the coordinates of each pixel point, and fill the map point by point in a one-to-one manner. Here, set the origin coordinate of the unit grayscale organization chart and the texture weave texture chart as (0, 〇), and then take the pixel coordinate (χ, Υ), 'and its grayscale value as an example, first calculate x The remainder after dividing by 8 with & and b respectively, the latitude float of the organization point (a, b) in the gray scale organization chart of the unit corresponding to G is the organization used when organizing at the point (x, y). . According to this method, each pixel of the image is organized and filled in sequence, and the result is similar to the original image.

Page 15 507032 V. Description of the invention (12) Weave texture chart of the same size. The main advantage of this method is that it can maintain the size of the original image and take into account the effect of the gray level of each pixel of the image, so the resolution is better. In order to test the aforementioned computer texture design method, the present invention selects a black pattern as an example of a texture design image. As shown in Annex 1, the color image size is 400x200 pixels (ie, χ = 400, γ = 200). First, the color image is grayscaled into a grayscale image. As shown in the third figure, it is still 400x200 pixels, and the grayscale value 6 of each pixel is between 0 and 255. And write a program with Visual Basic 6.0 to make 1 / tj 〇 / Ν υ 卞 how to organize under the method of the remainder and the remainder method, and obtain the texture organization chart of the image, as shown in the fourth figure. In more detail, the gray level of the 8 × 8 unit grid is hierarchical, as not shown in the first figure, and the gray level value G (between 0 ~ 255) of each pixel is appropriately distributed and converted into 49 levels. (For example: 0 ~ 5 is designated as the i-th stage, 6 ~ 10 is the second stage, and 11 ~ 15 is the third stage ... May be modified as appropriate). Assume that a certain point is located at (x = 212, y = 105) as the third order after the conversion, and the 8 × 8 unit gray level organization chart of the third order is the second one on the left in the upper row in the 8x8 area of the first figure , Χ = 212 divided by 8 to get the remainder a = 4, and y = i〇5 divided by 8 to get the remainder 1) = 1, and then the third position on the left side of the upper 8x8 unit gray scale organization chart ub) position , That is, (4,1) position, the corresponding color is obtained as black, so the corresponding point of the formed texture pattern (x = 212, y = 105) is entered into black, and the remainder is based on this Method to fill the map one by one point by point until all are completed. After that, weaving is done on the organization chart, and the way of weaving is that the black warp yarn passes through the steel reed and is fixed on the ^^ 疋 隹 proofing rack, and then according to the group

The texture organization charts from 8 x 8 to 4 are respectively:: gray :: weaving the organization. It can be clearly seen from the figure that the higher the contrast, the higher the contrast, the clearer the black and white, and the more gray levels, the more continuous the light and dark and the grayscale changes of the image = the clearer the outline of the black noise, and When the order change is discontinuous but the number of gray levels is small, the gray ^ β r ^ θ phenomenon forms the feeling of many blocks.
