It includes the following steps: First, the organization of the image under the digitalization step. Step 13 The establishment and calculation of the 13th-order grid.级 格子 一 ⑨ # #Image digitization step 1 1: First obtain a color image, use a t fetching device (such as a scanner, digital camera or other device) to obtain a digitized image, and each pixel has a red (R), green (G), and blue values, that is, R, G, and β values (these three values are all between 0 and 255), are stored in the computer ', and then select the appropriate Α χ β size Part of the color image is used as the design of the knitted double-sided color jacquard fabric. In fact, this embodiment is selected as the color image of the knitted double-sided color jacquard pattern of A χ β size. Refer to the second image (color (Please refer to Figure 1), Its image size is 400 × 400 pixels (ie, Α χ Β = 40 0 χ 400 pixels), and it is red, green, blue, white, and black (five color yarns) for double-sided jacquard knitting. Material design, the color scale grid size is 4 χ 4 (that is, N = 4), because the length ratio of the longitudinal loop (1 oop) to the transverse loop (1 oop) of the actual fabric is 2: 1 (this ratio may be due to Change in different situations

Page 8 554102 V. Description of the invention (6) changes), so first adjust the size of the original image coordinate axis X direction and y direction according to the ratio to 2 to 1 'to get a 400x200 image, this is the third image (color (Please refer to the appendix 1), and then use this image to calculate the fabric texture. I. Establishing and calculating steps of color grading grid 12: Select four to six colored yarns (at least two). Use the floating loop of each colored yarn in the knitting texture as a tissue point, and use the square of NXN tissue points. A grid is defined as a color level ^, where N should be between 3 and 6; using the least square difference method, a computer program is used to search for a combination of various color organization points to find the color level grid closest to the color of the pixel. · And the knitting points of the same color must be evenly distributed in the color gradation grid. In this embodiment, the knitted front yarn weaving pattern is woven with several colored yarns, combined with adjacent colored yarns. The color-neutral mixing effect between the floats expresses the colors of the original color image, and achieves the goal of visually similar to the original image color. Therefore, we choose five colored yarns (usually four to six), use the floating loops of each colored yarn in the knitting weave as an organization point, gather a certain number of organization points, and can be presented by neutral color mixing A visual blend of colors. Here, a certain number of organizational points is defined as a color gradation grid. Therefore, the color of each pixel in the image can be obtained by using the color neutral mixing principle to obtain the corresponding right bracket A 'γ in the corresponding color gradation grid. Lord, the points of various colored yarns in the mountain. For: Table = rich colors in the image 'The gradation grid must have sufficient organization ‘: The combination of color organization dots to create gradation grids representing various different colors ^. Therefore, the size of the color gradation grid will be qualitative; the larger the color gradation grid, the lower the resolution of the obtained color gradation image will be. ° color == but the use of image color solution white gun selection, visible Color image

Page 9 554102 V. Description of the invention (7) The size and resolution are selected according to the actual needs of the product. -In general, we use == square grids as color-level grids. From a practical point of view, in the Nx N color-level grids, the dots are organized by combining different colors, which can express different color-level grids. If you want to find a certain pixel = gradation grid, you are looking for the organization points of each color in this color gradation dumpling. Here you use the least square difference method to search for a combination of various color organization points with a computer program to find the pixels The closest color gradation grid = five-color jacquard, red, green, blue, white, and black, with 4 x 4 gradation grids as an example, as shown in the fourth picture (see Appendix 1 for color pictures), a total of 16 The organization point, the coordinates of the upper leftmost organization point are (0, 0), the upper right is (3, 丨), and so on. Assume that the number of dots of each color organization in a color scale grid is (r, g, b, w, k), the RGB color value of the red yarn is (255, 0, 0), and the rgb color value of the green yarn is (0 , 255, 0), the RGB color value of the blue yarn is (0, 〇, 255), and the color value of the white yarn is (255, 255, 255). The values are (R, G, B) = ((r + w) / 16x255, (g + w) / i6X255, (b + w) / 16x255), and assuming a color value at (x, y) pixels Is (R,, G ,, B,), you can use the least square difference method to search for the combination of points (r, g, b, w, k), so that (R, G, B) and (R, G (,, β,) has the smallest squared difference, that is, its color value is the closest. Then the color gradation grid arranged by the number of color organization points (rg, b, w, k) represents the color of the pixel. Take ( r, g, b, w, k) = (3, 3, 4, 3, 3) as an example, its color scale

Page 10 554102 V. Description of the invention (8) After the cells are sequentially filled in, as shown in the fourth figure, = 0) to (2, " In the row (1, 2), fill in the three green squares, and the rest can be deduced by analogy. (,) And the number follows: the prime points correspond to the color organization points in the color gradation grid; in the color gradation grid, # 由 neutral Mixing can show the color of the local U '. However, the arrangement of each color point in each color gradation grid will affect the specific background texture of the entire image visually disturbing the original image color .... blue and white or black or yellow (y) color respectively Let ’s design a knitted double-sided four / color or six ”j-weave pattern. In the case of five-color jacquard, the color arrangement of the five-color organization points such as red, AI-, white, and black should be considered. When the same organization point is too concentrated, Will cause the texture to form a regional block color, and then interfere with the image. The organization points of the same color must be distributed in the color scale grid. The method of designing the texture is to make double-sided jacquard fabrics of knitted computers. 'Knitted computer double-sided jacquard when weaving, @ 有 背 纹 组织 ^ To make the fabric non-floating The length of the circle is limited, so it is not necessary to consider the floating length of the yarn when filling the organization points in the color gradation grid. Therefore, there are no restrictions on the t points of each color group in the color gradation grid. Therefore, the color groups of the color gradation grid are arranged. When weaving dots, according to the principle of the number of dots of each color and uniform distribution, _ there are multiple arrangement methods to combine the dots of each color. Among the methods of arranging dots in a color grid, Arrangement methods such as ,, down · Take the five-color jacquard 4 X 4 color grid of red, green, blue, white, and black as an example. According to the cycle order of red, blue, white, black, and five colors, according to the number of organizational points Fill in each color's organization points one by one. When any of them-page 11 554102 Fifth invention description (9) Fill in the number of colors, that is, fill in the number of points τ ^. For example, == set the color until all Color organization »S > b, w, k) = (2 μ points of blue, white, and black organization (r is the color sequence of rgb, 3, 4, 5, 2). From left to right, from above W k Γ 舀 bwkgbwbww. Then again. According to the above, Fill =: Fill each organization point on the color scale grid (please refer to the attachment for the color chart—the color scale grid of j ^ is shown in the fifth picture, (2, 0) is blue, (3, 0) is white, '⑼ is red, d, 〇) is green, and beam. Then, (ι, υ is red, (彳) is treated as μ black, at this time the first cycle is white' (1, 2) is black, at this time the first Second cycle ',,,,,,' (3,1) is blue, (0,2) is exhausted, so the second cycle iaT #… bundle. At this moment, red and black blue, ㈧ * η & 6 Γ Fill in: (2, 2) is green, (3, 2) is supervised, (0, 3) is white, at this time the green has been, and ㈠ is assumed, then (1, 3) is blue, and (2 "The helmet occupies blue and white. So M χΓ〇 ox such as ~ (2,3) is white; finally, only white is left, and alienation (3, 3), that is, the yuan becomes a complete color scale. Step 13: Organize under the grid of order i and Λ. Step 13: Using the color obtained in the previous step, we can get a textured structure chart as shown in the sixth figure (see the first figure for the color chart). Make double-sided knitted jacquard fabric, the actual product is shown in the seventh picture (please knit attachment 1 for color pictures). This article adopts the method of organization, which is called the remainder method. Organizing with the remainder method 'can ensure that the texture of the texture pattern is the same as the original image, and keep the texture clear. This method is based on the pixel (X, y) coordinates in the color image, selects the corresponding tissue points with its corresponding color gradation grid, and fills the map in a one-to-one manner. Consider 4 × 4 color gradation grids and use

V. Description of the invention (10) The colored yarns are red, green, and five colors of the weaving structure of the shoe weave; five colors, black and black; assuming that 4x4 is a color gradation grid and (X νχ is labeled (0, 0), the original The coordinates of the pixel points of the image are horizontal, green, blue and white, and the horizontal direction is horizontal. The y direction is the continuous direction, and its red color: First, calculate the number of organizational points like Xin point 51 as r, g, b, w, and k. And respectively] ΐϊ The number of points and arrangement of each color in the gradation grid. The remainder obtained by dividing the 4 × 4 color coordinates χ and y by 4 is Na and shame, then the organization points at the (Na, Nb) coordinate position of image coordinate 枳 = , Which is the color of the tissue points used in the organization at the position of Γ × 2, X7 in the shadow method. In this way, ^ ^ can ensure that the size of the texture weave is the same as the original image, and the effect of "T is too large to weave the texture weave, and the texture design is kept clear." And manufacturing method, the generated texture group color has different effects due to the selection of the size of the gradation grid, the arrangement of the organization points, and the number of mixed Lou 3. The following will discuss the jacquard weave texture of different visual effects. The actual actual jacquard fabric sample after weaving is shown in the seventh picture (color picture 凊 see appendix 1). The picture can clearly see the whole colored picture f ', its color is close to the original color image, of which the big mouth The black neck is mainly represented by white yarn, while the black body is represented by black yarn. The color analysis is quite correct. In addition, the background level of the image is continuously and smoothly displayed, which can be described as a very successful weaving result, which proves that using this texture design method can be mixed to produce quite rich colors. Take five color yarns mixed, 4 X 4 color gradation grid as an example, can express 4845 colors. Therefore, the method used in this thesis has many color scale screens and presents visual effects that are quite close.

554102 V. Description of the invention (11) Similar to the original color image. In other words, the scheme uses the arrangement of the organization points in the color gradation grid, which can mix the knitting texture organization chart of tens of thousands of colors, far beyond the monotony of traditional and traditional knitted fabrics, with only color blocks and preliminary Weaving of wheels. Regarding the impact of different-sized color gradation grids, in practical terms, the size of the gradation grid should be between 3 X 3 and 6 X 6. Among them, the 3 X 3 gradation grid can be expressed by five-color mixing. 71 5 color scales; 4 χ 4 color scale grids are mixed with five colors to obtain 4,845 color scales; while 5 χ 5 color scale grids and 6 X 6 color scale grids are 23751 and 9 1 39 color scales, respectively. The more the number of color levels that are blended out, the more time it takes for the computer-aided calculation process. In order to take into account the overall efficiency, it is recommended to use a 4 x 4 color level grid as the texture design structure in the study. Regarding the effect of different ways of organizing the points, if different ways of organizing the points are arranged in the same color scale, it will produce different representations of the weave texture. Taking red, green, blue, white, black, and five-color jacquard 4 x 4 color gradation grids as an example, if you follow the order of red, green, blue, white, and black, fill in the number of tissue points of the same color in sequence, and then fill in One color organization point, until all colors are rotated, the obtained texture organization chart will be as shown in the eighth figure. Comparing this organization chart with the sixth image, it is obvious that the texture organization chart in the eighth figure has special lines showing horizontal lines to interfere with the image, and the image showing lines is not smooth. Therefore, using the uniform distribution method of the sixth figure obtained by using the aforementioned average distribution method, the texture effect of the textured texture chart is better. To sum up, this case proposes a double-sided knitting

Page 14 554102 V. Description of the invention (12) The method of making floral fabrics uses color-graded lattice surface jacquard knitted fabrics to be rich in color, and the texture image proposed by the film is converted to a double-sided structure diagram. The above are just examples.任 范围。 Any range. From the above details, the aforementioned patent application can be achieved.
