Description

Technical Field

[0001] The present invention relates to the technical field of knitting fabric design, and particularly to a method, device, equipment and storage medium for decomposing and transforming knitting patterns. Background Art

[0002] The computer jacquard needle selection system of a circular knitting machine needs to transform the pattern to form a data file containing knitting jacquard technology. At present, in the field of circular knitting machines, the jacquard decomposition and transformation on the market all adopt software with WAC technology. This decomposition and transformation method is only applicable to process models with ordinary requirements. As people's demand for clothing fabrics is getting higher and higher, the pattern size is getting larger and larger, the knitting function of the machine is getting richer and richer, and the intelligence level of the machine is getting higher and higher. This puts forward higher requirements for pattern designers.

[0003] It takes designers longer and longer to design a pattern file that meets the corresponding knitting process. Due to the large pattern size and complex process, a large amount of time and energy are required only for pattern decomposition and synthesis. If there is a slight mistake, errors will occur when debugging the cloth sample on the machine. Sometimes, the error points are very difficult to find and need to be repeatedly modified and tested. Eventually, the efficiency of knitting cloth sample proofing is low, and the waste of knitting raw materials is serious. From the design of a pattern to its production, it takes a lot of time, resulting in increased costs. Prolonging the delivery time will also cause economic losses to customers. It can be seen that the existing technology still needs to be improved. Summary of the Invention

[0028] Embodiment 1

[0029] Please refer to Figures 1 to 8 , the present invention provides a method for decomposing and transforming knitting patterns, including the following steps: 101. Import a drawing with a pattern and convert it into a true-color image; 102. Convert the true-color image into an original pixel map, and preset a process texture template, where the process texture template includes at least one row of texture; 103. Identify that the number of rows of the original pixel map is M, where M is an integer and not 0, and disassemble each row of the original pixel map as a disassembly unit to obtain M disassembly files; 104. Set the number of rows of the replacement texture to N according to the disassembly files, where N is an integer and greater than 1, and lay each row of the replacement texture by calling the process texture template according to the color arrangement in each disassembly file to obtain a unit design drawing with N rows; 105. Arrange and splice the M unit design drawings to obtain a complete design drawing with M*N rows; and convert the complete design drawing into electronic card data for knitting and weaving. Converting the drawing into an original pixel map is beneficial for dividing the disassembly unit and performing disassembly, simplifying the disassembly process of patterns with large sizes and complex processes. Laying the replacement texture by calling the process texture template can effectively reduce the time and effort required for design. The clearly distinguishable unit design drawings can easily reveal error points during the review process, avoid repeated modification, improve the efficiency of knitting sample making, and reduce waste of knitting raw materials. In addition, the optimization of the decomposition and transformation process can also provide convenience for convenient editing and quick viewing in design, greatly improving the efficiency of design creation.

[0030] In this embodiment, presetting the process texture template specifically means generating a process texture template according to the creative requirements, including creating a new process texture template or selecting a preset process texture template. That is, the designer can re-create a process texture template according to the creative requirements or select a preset process texture template from the database. It can be understood that the re-created process texture template is automatically stored in the database after being saved, which is convenient for the designer to select as a preset process texture template during the next design.

[0031] Specifically, set the number of rows of the replacement pattern as N according to the disassembly file, where N is an integer greater than 1. According to the color arrangement in each disassembly file, call the process pattern template to lay each row in the replacement pattern to obtain a unit design drawing with N rows, including: 201. Obtain the color arrangement in the disassembly file and distinguish the color characteristics of each cell; 202. In each row of the replacement pattern, set a replacement rule for the color characteristics; 203. Lay each cell in the replacement pattern according to the replacement rule to obtain a unit design drawing with N rows. Specifically, in each row of the replacement pattern, set a replacement rule for the color characteristics, including: the unit design drawing with N rows includes at least one target row, extract a row of pattern from the process pattern template as the target pattern; lay the target pattern in any target row of the replacement pattern. More specifically, extract a row of pattern from the process pattern template as the target pattern; lay the target pattern in any target row of the replacement pattern, including: the unit design drawing with N rows also includes a filling row, select any color as the filling color for a certain color characteristic, and lay the filling color in any filling row of the replacement pattern.

Please refer to Figure 5 , the process pattern template is an image of a two-row and three-column array, where the cell colors in the first row are green, white, and green in sequence; the cell colors in the second row are white, blue, and gray in sequence; in this embodiment, each row of the process pattern template is sequentially extracted for laying the replacement pattern.

[0033] Please refer to Figure 6 , the original pixel map is disassembled into three disassembly files. The color arrangement of the first disassembly file is: green - green - green - blue - blue, and the number of rows of the replacement pattern is set to 3. The set replacement rule is: in the first row of the replacement pattern, replace green with red and mark blue as blank; in the second row, mark green as blank and keep blue unchanged; in the third row, extract the first row from the process pattern template to replace green and mark blue as blank. Extract the first row of the process pattern template for laying, and through conversion, the first row of the first replacement pattern is: red - red - red - blank - blank; the second row is: blank - blank - blank - blue - blue; the third row is: green - white - green - blank - blank.

[0034] Please refer to Figure 7, the color sorting of the second disassembled file is: green - green - green - green - blue, and the number of rows of the replacement pattern is set to 3. The set replacement rule is: in the first row of the replacement pattern, green is replaced with red and blue is marked as blank; in the second row, green is marked as blank and blue remains unchanged; in the third row, the first row is extracted from the process pattern template to replace green and blue is marked as blank. The second row of the process pattern template is extracted for laying, and through conversion, the first row of the second replacement pattern is: red - red - red - red - blank; the second row is: blank - blank - blank - blank - blue; the third row is: white - blue - gray - white - blank.

[0035] Please refer to Figure 8 , the color sorting of the third disassembled file is: green - green - green - green - blue, and the number of rows of the replacement pattern is set to 3. The set replacement rule is: in the first row of the replacement pattern, green is replaced with red and blue is marked as blank; in the second row, green is marked as blank and blue remains unchanged; in the third row, the first row is extracted from the process pattern template to replace green and blue is marked as blank, and the replacement process is circular laying. The first row of the process pattern template is repeatedly extracted for laying, and through conversion, the first row of the third replacement pattern is: red - red - red - red - blank; the second row is: blank - blank - blank - blank - blue; the third row is: green - white - green - green - blank.

[0036] Optionally, it includes: confirming that the number of rows of the original pixel map is M; using pattern CAD software to disassemble the original pixel map; obtaining M disassembled files; that is, during the sequential disassembly process with each row of the original pixel map as the disassembly unit, using pattern CAD software to sequentially disassemble the original pixel map. More specifically, M unit jacquard diagrams are arranged and spliced to obtain a complete jacquard diagram with M * N rows; the complete jacquard diagram is converted into electronic card data for knitting and weaving, including: 301. During disassembly, sequence numbers are assigned to the disassembly sequence of each disassembly unit and marked in the corresponding unit jacquard diagram; 302. Multiple unit jacquard diagrams are spliced and organized according to the sequence numbers to obtain a complete jacquard diagram; 303. The complete jacquard diagram is converted into electronic card data for knitting and weaving by a design computer; specifically, the electronic card data is transmitted from the design computer to the knitting machine computer; the knitting machine computer performs knitting and weaving according to the electronic card data. That is, M unit jacquard diagrams are spliced in the order of the disassembly units of the original pixel map.

[0037] The first disassembled file, the second disassembled file, and the third disassembled file in the above example are sequentially spliced to obtain a complete jacquard diagram. The number of rows of the above complete jacquard diagram is 9 rows, and the number of columns is 5 columns, forming a complete jacquard diagram in a 5-column 9-row array.
