Description

Technical Field

[0001] This invention relates to the field of knitted fabric design technology, and in particular to a method, apparatus, equipment and storage medium for decomposing and transforming knitted patterns. Background Technology

[0002] In the field of circular knitting machines, computerized jacquard needle selection systems must first convert the pattern into a data file containing jacquard knitting process parameters before driving the machine to knit. Currently, most jacquard decomposition and conversion systems on the market rely on WAC process software, which is only compatible with ordinary process machines and is insufficient to meet the increasingly complex pattern requirements. Under current technology, designers spend a lot of time designing pattern files that meet the process requirements, and pattern decomposition and synthesis require a lot of effort. Due to the large size and complex process, it is easy to make mistakes when debugging fabric samples, and the errors are difficult to locate, resulting in repeated modifications and tests, low efficiency in fabric pattern making, and serious waste of raw materials. The excessively long cycle from design to production not only increases production costs but also extends delivery time, causing economic losses to enterprises and customers.

[0003] Although a patent (patent number: CN116497515B) proposes a knitted pattern decomposition and transformation scheme, which simplifies the decomposition process and improves efficiency to some extent by disassembling the original pixel image row by row and calling the process texture template to lay out the replacement texture, this scheme can only use a uniform decomposition mode for a single pattern image. All decomposition units must follow the same texture replacement row setting. However, in actual production, complex patterns often need to be adapted to different processes for different areas (such as some areas need fine textures and some areas need simplified textures). A uniform replacement row number cannot meet the needs of multiple processes and still requires manual adjustment, which not only increases the workload but also easily introduces errors, failing to completely solve the problem of adaptability and efficiency of complex pattern design. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a method for decomposing and transforming knitted patterns, which improves design flexibility, meets the needs of multi-regional processes, reduces decomposition and synthesis time, and solves the problem that the traditional solution of uniformly replacing rows cannot meet the needs of multiple processes.

[0011] Optionally, in a sixth implementation of the first aspect of the present invention, the step of splicing the set of unit design drawings to obtain a complete design drawing includes: obtaining the sequence number of each disassembly unit in each partition region; adding the sequence number to the unit design drawing corresponding to the disassembly unit to obtain a set of unit design drawings with sequence numbers corresponding to each partition region; performing a splicing operation on the set of unit design drawings according to the sequence number to obtain multiple region design drawings; and splicing the multiple region design drawings to obtain the complete design drawing.

Detailed Implementation

[0017] This invention provides a method, apparatus, device, and storage medium for decomposing and transforming knitted patterns. In this invention, the terms "first," "second," "third," "fourth," etc. (if present)," in the specification, claims, and accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" or "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0018] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 One embodiment of the knitting pattern decomposition and transformation method in this invention includes: 101. Obtain the original pixel image, and perform region selection on the original pixel image to obtain multiple partition regions; In this embodiment, areas can be divided according to different process characteristics. For example, areas with fine patterns requiring high weaving density, areas with basic patterns of low density, and areas with multi-color layering can be divided independently to form multiple non-overlapping partitioned areas. By matching process parameters to partitions, waste of raw materials caused by over-processing can be avoided. At the same time, the machine can weave efficiently according to the characteristics of each area, improving the success rate of fabric pattern making and production efficiency.

[0019] 102. Each partition area is disassembled separately to obtain disassembly information corresponding to each partition area. The disassembly information includes multiple disassembly units. In this embodiment, as the size of the flower pattern increases and the complexity of the process improves, directly setting process parameters and replacing textures on the complete flower pattern image is prone to processing bottlenecks and parameter setting conflicts due to the large amount of data, and it is difficult to accurately locate local process requirements. However, by decomposing each partition area separately, decomposition information corresponding to each partition area is obtained. The decomposition information includes multiple decomposition units, which can break down large-scale and complex flower pattern data into several independent small data units. Each decomposition unit corresponds to only one row of pixels of the flower pattern, which greatly reduces the processing difficulty of individual data units and makes subsequent operations such as color arrangement analysis and texture replacement rule setting easier to execute, effectively simplifying the overall processing of large-sized and complex flower patterns.

[0020] 103. Based on the disassembly information of each partition area, set the texture replacement rules respectively to obtain the texture replacement rules corresponding to each partition area; In this embodiment, when faced with complex patterns, if there is no unified pattern replacement rule, the designer needs to replan the pattern when dealing with each pattern, which is time-consuming and labor-intensive. After setting the rule, the replacement method can be quickly determined based on the color characteristics, reducing the time and effort required for design. Moreover, different pattern replacement rules can be set for different partition areas, which solves the problem that a single rule cannot take into account the process differences of multiple areas.

[0021] 104. According to the texture replacement rules, the disassembly information of the corresponding partition areas is processed to obtain a set of unit design drawings corresponding to each partition area; In this embodiment, the laying operation transforms abstract color information into a texture structure with practical weaving process significance. Each disassembly unit in the disassembly information generates a unit design diagram with N rows, where N is the preset number of replacement texture rows in the texture replacement rules. This effectively simplifies the process conversion of complex patterns. Compared to the texture chaos that easily occurs with traditional irregular laying, this operation, through regular mapping, can quickly convert large-size, multi-color disassembly files into standardized unit design diagrams, reducing the time and effort required for design. Furthermore, it ensures that the laid unit design diagram accurately matches the expected texture effect, avoiding color and texture misalignment caused by irregular laying and guaranteeing the pattern quality of subsequent woven products.

[0022] 105. The set of unit design drawings is spliced ​​together to obtain a complete design drawing; In this embodiment, the scattered unit design drawings are reintegrated into complete pattern data, which solves the problem of data fragmentation after disassembly and ensures that the final generated design drawing can fully present the pattern details and color distribution of the original pattern, avoiding pattern loss or misalignment caused by data dispersion.

[0023] 106. Convert the complete design drawing into electronic pattern data for weaving manufacturing.

[0024] In this embodiment, the visual and technological information, such as the pattern, color distribution, and texture structure contained in the complete design drawing, is transformed into a set of digital process parameters (i.e., electronic pattern data used for knitting manufacturing) that can be recognized and read by the computer of the knitting machine. These data cover the key instructions related to jacquard needle selection and loop knitting in the knitting process, which can directly drive the circular knitting machine to complete the knitting operation according to the design requirements. This realizes the effective transformation of pattern design information into production execution data, and solves the problems of low efficiency, poor accuracy, and difficulty in adapting to complex patterns in traditional manual pattern making. It enables the designed pattern to be quickly transformed into machine-executable process instructions, ensuring that the knitting process accurately reproduces the pattern design effect.

[0025] This application discloses a method for decomposing and transforming knitted patterns. By selecting regions from the acquired original image, multiple partitioned regions are obtained. Each partitioned region is then decomposed to obtain corresponding decomposition information. Based on the decomposition information of each partitioned region, texture replacement rules are set to obtain texture replacement rules corresponding to each partitioned region. The decomposition information of the corresponding partitioned regions is then processed according to the texture replacement rules to obtain a set of unit design images corresponding to each partitioned region. Finally, the set of unit design images is spliced ​​to obtain a complete design image, which is then converted into electronic pattern data for knitting manufacturing. This method improves design flexibility, meets the needs of multi-region processes, reduces decomposition and synthesis time, and solves the problem that traditional solutions can only generate a fixed decomposition mode for a single pattern image, making it impossible to flexibly adjust according to the multiple process requirements in actual production.

[0026] In this embodiment of the invention, before obtaining the original pixel image and performing region selection on the original pixel image to obtain multiple partitioned regions, the method further includes: obtaining a drawing image with a pattern; performing color mapping processing on the drawing image to generate a true-color image; and performing pixel processing on the true-color image to generate the original pixel image.

[0027] In this embodiment, a patterned drawing is first obtained. Then, based on the color system of the drawing (which may be grayscale, pseudocolor, or specific coded colors), a correspondence between it and the true color RGB space is established. Through color mapping processing, the color information of the drawing is converted into a true color image where each pixel contains three channels (red, green, and blue, 8 bits each, for a total of 24 bits) and can display approximately 16.7 million colors. Then, the true color image is subjected to pixel-level standardization processing (such as unifying pixel resolution, determining the number of rows and columns of the pixel array, and extracting the color value of each pixel). Finally, a clear original pixel image with well-defined structure and clear color data is generated. By converting the drawn image into a true-color image through color mapping, the color details and visual effects of the floral design can be fully preserved, avoiding the loss of design information due to incompatible color systems. Furthermore, by generating original pixel images through pixel processing, the true-color image can be transformed into structured data that is easy to divide into subdivision units, making subsequent disassembly operations easier to perform. This effectively simplifies the subsequent processing flow for large-sized and complex floral designs. At the same time, standardized original pixel images reduce errors in subsequent disassembly and process adaptation stages, improving the efficiency and accuracy of floral design decomposition and transformation. In this embodiment of the invention, the step of obtaining the original pixel image and performing region selection on the original pixel image to obtain multiple partitioned regions includes: obtaining the original pixel image; in response to multiple bounding box operations performed by the user on the original pixel image, obtaining multiple bounding box regions formed by the user's bounding box selection; for each bounding box region, using the height of the bounding box region as the vertical dimension and the width of the original pixel image as the horizontal dimension, determining the region defined by the vertical dimension and the horizontal dimension as a partitioned region, thereby obtaining multiple non-overlapping partitioned regions.

[0028] In this embodiment, the system responds to multiple selection actions performed by the user through the interface, capturing the range defined by each selection as the selection area. Then, for each selection area, its vertical (height) dimension is retained as the vertical dimension of the partitioned area, while the width of the original pixel image is used as the horizontal dimension. The resulting rectangular area is a single partitioned area. If there are areas not selected by the user, these areas are defaulted to the same partitioned area. For example, if the user performs two selections through the interface, resulting in a first and a second partitioned area, the remaining unselected area is the default partitioned area. The multiple partitioned areas obtained in this way do not overlap in the original pixel image, collectively covering the entire range of the original pixel image. By unifying the horizontal dimensions, each partitioned area maintains consistency in the horizontal dimension, avoiding data misalignment during subsequent row-by-row splitting and texture laying due to differences in horizontal dimensions.

[0029] In this embodiment of the invention, each partition region is disassembled to obtain disassembly information corresponding to each partition region. The disassembly information includes multiple disassembly units, including: performing row number identification processing on each partition region to obtain the row number corresponding to each partition region; performing row-by-row disassembly operation on each partition region based on the row number of each partition region to generate disassembly information containing multiple disassembly units, and sequentially labeling each disassembly unit of each partition region according to the disassembly order.

[0030] In this embodiment, the knitting process of the circular knitting machine is based on the "row" as the basic time unit. The loops are knitted row by row along the longitudinal direction. The presentation of the pattern must be consistent with the physical knitting rhythm of the machine. Row-by-row decomposition allows the decomposition unit of the pattern data to directly correspond to the actual knitting unit of the machine, avoiding subsequent data conversion deviations caused by misalignment between the decomposition dimension and the process rhythm. At the same time, the pixel color arrangement within each row of the original pixel image is continuous. Row-by-row decomposition can completely preserve the color distribution characteristics of each row without the need to divide pixels across rows, thus avoiding damage to the integrity of the local pattern. Especially for large-sized and complex patterns, it can split large-scale data into several independent small decomposition files, reducing the processing difficulty of individual data units and providing a clear data foundation for setting pattern replacement rules according to color arrangement.

[0031] In this embodiment, since the disassembled units need to generate unit design images separately and then be reassembled into a complete design image, if there is no clear sequence label, the splicing order of the unit design images is likely to be chaotic, resulting in misalignment and distortion of the pattern in the complete design image. Therefore, numbering the sequence during the disassembly process can accurately record the position order of each disassembled unit in the original pixel image, ensuring that the row and column logic of the original pattern can be strictly followed during subsequent splicing.

[0032] In this embodiment of the invention, the step of setting texture replacement rules based on the disassembly information of each partition region to obtain texture replacement rules corresponding to each partition region includes: obtaining a preset number of replacement texture rows corresponding to each partition region; obtaining the color arrangement of multiple disassembly units to obtain color features corresponding to each partition region; and setting texture replacement rules corresponding to each partition region based on the number of replacement texture rows and the color features.

[0033] In this embodiment, after the original pixel image is partitioned, the number of replacement texture rows (i.e., the number of vertical rows required when each disassembly unit generates a unit design image) is retrieved according to the process requirements of each partition. The number of replacement texture rows in each partition can be different or the same. Then, the color arrangement information of all disassembly units in each partition is extracted to form corresponding color features. Finally, based on the preset number of replacement texture rows as a framework and combined with the color features of the partition, a texture replacement rule adapted to the partition is formulated, so that the texture replacement rule of each partition not only meets the row number requirement but also accurately matches its own color distribution characteristics. By matching a preset number of replacement texture rows to each partition, the differentiated process requirements of different partitions can be met, avoiding the limitations of a single row number setting. Formulating rules based on color features can ensure that the texture and color depth are matched, avoiding mismatch problems caused by uniform rules and ensuring the pattern reproduction accuracy.

[0034] In this embodiment of the invention, the step of laying out the disassembly information of the corresponding partition area according to the texture replacement rule to obtain a set of unit design diagrams corresponding to each partition area includes: obtaining a preset process texture template, the process texture template including at least one row of textures; identifying cells of the disassembly information corresponding to each partition area to obtain multiple cells; laying out each cell of the corresponding partition area according to the texture replacement rule corresponding to each partition area to obtain a set of unit design diagrams corresponding to each partition area, the set of unit design diagrams including multiple unit design diagrams, wherein each unit design diagram includes at least one target row, extracting a row of textures from the process texture template as a target texture, and laying the target texture in the target row.

[0035] In this embodiment, the preset process texture template is specifically generated according to creative needs, including creating a new process texture template or selecting a preset process texture template. That is, the designer can recreate the process texture template according to creative needs, or select a preset process texture template from the database. It can be understood that the recreated process texture template is automatically stored in the database after being saved, so that the designer can use it as a preset process texture template in the next design.

[0036] In this embodiment, after setting the texture replacement rules for the partitioned areas, the cells of the disassembly information for each partitioned area are first identified, that is, the cells of multiple disassembly units in the disassembly information are identified to obtain multiple cells. Then, according to the corresponding texture replacement rules, each cell is processed to obtain a set of unit design diagrams corresponding to each partitioned area. The set of unit design diagrams includes multiple unit design diagrams. Each unit design diagram includes at least one target row. A texture is extracted from the process texture template as the target texture and laid in the target row. In addition, each unit design diagram also includes a fill row. Any color is selected as the fill color of a certain color feature and laid in any fill row of the replacement texture.

[0037] Please refer to Figure 2 and Figure 8 In this embodiment, for ease of understanding, the following example is used for illustration: Figure 2As shown, the original pixel image is a five-column, five-row array. In the first row, the first three cells are green and the last two are blue; in the second row, the first four cells are green and the last cell is blue; in the third row, the first two cells are green and the last two are blue; in the fourth row, the first three cells are green and the last two are blue; and in the fifth row, the first three cells are green and the last two are blue. This five-column, five-row array image is then partitioned. The first and second rows are designated as the first partition, and the third through fifth rows are designated as the second partition. Please refer to [link / reference]. Figure 3 The process texture template is a two-row, three-column array image, where the cell colors in the first row are green, white, and green respectively; the cell colors in the second row are white, blue, and gray respectively; in this embodiment, each row of the process texture template is extracted sequentially to lay the replacement texture.

[0038] Please see Figure 4 and Figure 5 Taking the laying process of each cell in the first partition area as an example, the disassembly information of the first partition area includes two disassembly units, namely the first disassembly unit and the second disassembly unit.

[0039] Please see Figure 4 The color arrangement of the first disassembly unit is: green-green-green-blue-blue, with 3 rows of replacement patterns. The replacement rules are as follows: in the first row, green is replaced with red, and blue is left blank; in the second row, green is left blank, and blue remains unchanged; in the third row, the first row of the process pattern template is extracted and replaced with green, and blue is left blank. The first row of the extracted process pattern template is then laid out, resulting in the following replacement patterns: first row: red-red-red-blank-blank; second row: blank-blank-blank-blue-blue; third row: green-white-green-blank-blank.

[0040] Please see Figure 5 The second disassembly unit's color arrangement is: green-green-green-green-blue, with 3 rows of replacement patterns. The replacement rules are: in the first row, green is replaced with red, and blue is left blank; in the second row, green is left blank, and blue remains unchanged; in the third row, the second row is extracted from the process pattern template, replacing green, and blue is left blank. The second row of the extracted process pattern template is then applied, resulting in the second replacement pattern: first row: red-red-red-red-blank; second row: blank-blank-blank-blank-blue; third row: white-blue-gray-white-blank.

[0041] Please see Figure 6 , Figure 7 and Figure 8 Taking the laying process of each cell in the second partition area as an example, the disassembly information of the second partition area includes three disassembly units, namely the third disassembly unit, the fourth disassembly unit and the fifth disassembly unit.

[0042] Please see Figure 6 The color arrangement of the third disassembly unit is: green-green-blue-blue-blue, with 2 rows of replacement patterns. The replacement rules are: the first row of replacement patterns has no green pattern (i.e., blank), and blue is replaced with red. The second row is extracted from the process pattern template, replacing green, and blue is left blank. The first row of the extracted process pattern template is then laid out, resulting in the following first row of replacement patterns: blank-blank-red-red-red; the second row is: green-white-green-blank-blank.

[0043] Please see Figure 7 The fourth disassembly unit's color arrangement is: green-green-green-blue-blue, with two rows of replacement patterns. The replacement rules are: in the first row, green is replaced with red, and blue is left blank; in the second row, the second row is extracted from the pattern template, replacing green and blue with red. The first row of the extracted pattern template is laid out, resulting in the first row of the first replacement pattern being: red-red-red-blank-blank; and the second row being: white-blue-gray-red-red-red.

[0044] Please see Figure 8 The fifth disassembly unit's color arrangement is: green-green-green-blue-blue, with two rows of replacement patterns. The replacement rules are: the first row of replacement patterns leaves green unchanged and blue blank; the second row extracts the first row from the pattern template, replacing green and replacing blue with red. The first row of the extracted pattern template is then laid out, resulting in the first row of the first replacement pattern being: green-green-green-blank-blank; the second row being: green-white-green-red-red.

[0045] In this embodiment of the invention, the step of stitching together the set of unit design drawings to obtain a complete design drawing includes: obtaining the sequence number of each disassembly unit in each partition region; adding the sequence number to the unit design drawing corresponding to the disassembly unit to obtain a set of unit design drawings with sequence numbers corresponding to each partition region; performing a stitching operation on the set of unit design drawings according to the sequence number to obtain multiple region design drawings; and stitching together the multiple region design drawings to obtain the complete design drawing.

[0046] In this embodiment, after generating the unit design diagrams for each partition, the sequence numbers marked during the previous disassembly are extracted from the disassembly units within each partition, and these sequence numbers are added to the unit design diagrams generated by each disassembly unit. This makes each partition a set of unit design diagrams containing sequence numbers. Then, based on the sequence numbers, the unit design diagram sets for each partition are vertically arranged and stitched together according to the original row order to form a region design diagram that can completely present the pattern information of that partition. Finally, the region design diagrams of all partitions are stitched together according to their positional relationship in the original pixel image, resulting in a complete design diagram that covers all the information of the original pattern and has a complete row and column structure. By adding sequence numbers to the unit design diagrams, the position of each unit design diagram in the original pattern can be accurately located, avoiding row order confusion when stitching unit design diagrams within a single partition, and ensuring that the region design diagram can completely restore the pattern logic within the partition. For example, as... Figures 2 to 8 As shown, in the example above, after the first and second disassembly units perform the laying process, they obtain a first unit design image and a second unit design image. By sequentially splicing the first and second unit design images, the first region design image is obtained. Similarly, after the third, fourth, and fifth disassembly units perform the laying process, they obtain a third unit design image, a fourth unit design image, and a fifth unit design image. By sequentially splicing the third, fourth, and fifth unit design images, the second region design image is obtained. Finally, the first and second region design images are spliced ​​together according to their positional relationship in the original pixel image to obtain a complete design image. This complete design image has 12 rows and 5 columns, forming a 5-column, 12-row matrix.
