Description

Technical Field

[0001] The invention belongs to the technical field of sewing clothing patterns, and in particular relates to a method and a system for sewing digital clothing patterns. Background Art

[0002] Garment patterns, also known as sample pieces, are a tool used in clothing design and production. The shape and size of clothing patterns are similar to real clothing. They usually have the basic outline of the human body and can display and record information such as the design, appearance and size of clothing. Clothing designers can draw design patterns, add fabric samples, and mark sizes on clothing patterns, which helps designers visualize and evaluate creative ideas, and use them as templates for sample garments for reference and reproduction. They can also be used to display, demonstrate and record design details, cutting sizes and other information during the production process.

[0003] In garment production, pattern sewing is a very important process. Pattern sewing is the process of connecting different parts of a garment pattern with each other by sewing machines or by hand to simulate the production process of real garments. During the sewing process, designers will precisely stitch together different garment pattern parts according to the design pattern and structural requirements. This can better predict and solve possible problems, and adjust design details to ensure that the overall shape, tailoring, fit, appearance and structure of the garment meet expectations.

[0004] In the prior art, when specifying stitching, the edge is mainly used as the smallest granularity object. When multiple continuous edges connected end to end need to be stitched, the interaction is more complicated. At the same time, when facing segmentation, multiple line segments need to be selected. When the basic functions of digital clothing production are not optimized, the operation is more complicated, which also makes the interaction more difficult. Summary of the invention

[0005] In order to overcome the defects of the prior art, the present invention proposes a method for sewing digital clothing patterns, characterized in that the method comprises:

[0006] After receiving the first instruction, determining a first starting point based on a first coordinate point where the indicated coordinates are currently located;

[0007] Detecting a range of movement of the indicated coordinates, so as to determine a first direction based on a current location of the indicated coordinates and the first starting point when the range of movement of the indicated coordinates exceeds a preset first threshold;

[0008] After receiving the second instruction, determining a first end point based on a second coordinate point where the indicated coordinate is currently located, and generating a first sewing line based on the first starting point, the first end point and the first direction; the first starting point, the first end point and the generated first sewing line correspond to the same digital garment pattern;

[0009] Repeat the above steps to determine a second starting point, a second end point and a second direction and generate a second sewing line; the second starting point, the second end point and the generated second sewing line correspond to the same digital garment pattern;

[0010] The digital garment pattern is sewn based on the first sewing line and the second sewing line.

[0011] Specifically, the “after receiving the first instruction, determining the first starting point based on the first coordinate point where the indicated coordinates are currently located” includes:

[0012] After receiving the first instruction, searching whether there is a vertex of the digital clothing pattern within a second threshold range of the first coordinate point;

[0013] If there is a vertex of the digital clothing pattern, determine the vertex closest to the first coordinate point as the first starting point;

[0014] If there is no vertex of the digital clothing pattern, searching whether there is a contour line of the digital clothing pattern within a second threshold range of the first coordinate point;

[0015] If there is an outline of the digital garment pattern, the vertex on the outline that is closest to the first coordinate point is determined as the first starting point.

[0016] Specifically, the “determining the first direction based on the current location of the indicated coordinates and the first starting point” includes:

[0017] Setting each contour line with the first starting point as an endpoint as a detection line, detecting the distance between the current point of the indicated coordinate and each detection line, and determining the detection line closest to the current point of the indicated coordinate as a direction line;

[0018] The direction extending from the first starting point to the other end of the direction line is determined as the first direction.

[0019] Preferably, the method further comprises:

[0020] After determining the first direction, prompting the user to determine whether the first direction is correct;

[0021] If the judgment result is no, the first direction after being reversed is re-determined as the first direction.

[0022] Specifically, the “after receiving the second instruction, determining the first end point based on the second coordinate point where the indicated coordinates are currently located” includes:

[0023] After receiving the second instruction, searching whether there is a vertex of the digital clothing pattern within a third threshold range of the second coordinate point;

[0024] If so, determining the vertex closest to the second coordinate point as the first end point;

[0025] If it does not exist, the second coordinate point is determined as the first end point.

[0026] Furthermore, the method further comprises:

[0027] After determining the first end point, if a third instruction is received, cancel the previous first end point, and based on the previous first direction, extend the first direction based on the most recently canceled first end point and the current location of the indicated coordinates;

[0028] After receiving the second instruction, re-determine the first end point based on the coordinate point where the indicated coordinates are currently located;

[0029] Repeat the above steps until it is determined that the coordinate point where the indicated coordinates are currently located is the final first end point, and generate the first sewing line based on the first starting point, the first end point and the first direction.

[0030] Preferably, the indication coordinates include a mouse pointer.

[0031] Preferably, the method further comprises:

[0032] When the first instruction is not received, or when the first direction is determined and the second instruction is not received, if there is a vertex of the digital garment pattern within a fourth threshold range of the indicated coordinates, aligning the indicated coordinates to the nearest vertex;

[0033] And / or, if there is a cutting edge point of the digital garment pattern within a fifth threshold range of the indicated coordinates, aligning the indicated coordinates to the cutting edge point.

[0035] A starting point determination module, configured to determine a first starting point based on a first coordinate point where the indicated coordinates are currently located after receiving a first instruction;

[0036] a direction determination module, configured to detect a range of movement of the indicated coordinates, so as to determine a first direction based on a current location of the indicated coordinates and the first starting point when the range of movement of the indicated coordinates exceeds a preset first threshold;

[0037] a generating module, configured to, after receiving a second instruction, determine a first end point based on a second coordinate point where the indicated coordinate is currently located, and generate a first sewing line based on the first starting point, the first end point and the first direction; the first starting point, the first end point and the generated first sewing line correspond to the same digital garment pattern;

[0038] a secondary generation module, configured to cause the starting point determination module, the direction determination module and the generation module to repeatedly execute preset steps to determine a second starting point, a second end point and a second direction and generate a second sewing line; the second starting point, the second end point and the generated second sewing line correspond to the same digital garment pattern;

[0039] A sewing module is used to sew the digital garment pattern based on the first sewing line and the second sewing line.

[0040] The present invention has at least the following beneficial effects:

[0041] The solution proposed by the present invention can quickly determine the starting point, end point and direction required for generating a stitching line according to instructions, reducing the need for manual operation, and is simple to operate, easy to use and convenient to adjust, so that users can sew digital clothing patterns efficiently and accurately;

[0042] Furthermore, this solution flexibly utilizes the vertices and contours of the digital clothing pattern to determine the starting point and direction, and can use the mouse pointer as the indicated coordinates, which is more in line with the operation of stitching digital clothing patterns. It considers aligning the indicated coordinates to the vertices and cutting edge points of the clothing pattern, providing convenience for users. At the same time, the solution can be applied to the stitching of multiple line segments and multiple patterns, and has a wide range of applicable scenarios.

[0043] Therefore, the present invention provides a method and system for stitching digital clothing patterns. The scheme operates based on instructions and coordinate points, can automatically determine the starting point, end point and direction and quickly generate stitching lines, reducing the need for manual operation, while ensuring the accuracy and precision of the stitching lines, thereby improving the efficiency and accuracy of plate making, and effectively saving time and labor costs.

[0065] Example 1

[0066] This embodiment provides a method for stitching digital clothing patterns. Figure 1-3 , the method comprising:

[0067] S100: After receiving the first instruction, determine a first starting point based on a first coordinate point where the indicated coordinates are currently located.

[0068] S200: Detecting a moving range of the indicated coordinates, and when the moving range of the indicated coordinates exceeds a preset first threshold, determining a first direction based on a first line segment generated by connecting a current point of the indicated coordinates and a first starting point.

[0069] It should be noted that the purpose of setting the first threshold is to correctly determine the first direction according to the moving direction of the indicated coordinates. Therefore, the indicated coordinates need to exceed a certain range before the first direction can be determined, especially when multiple lines are connected end to end to form a Figure 4 In the case of the direction of the quasi-annular or arc-shaped edge shown, this method can have a more superior effect. In a specific embodiment, the first threshold can be 3-10 pixels.

[0070] S300: After receiving the second instruction, determine the first end point based on the second coordinate point where the indicated coordinate is currently located, and generate a first sewing line based on the first starting point, the first end point and the first direction.

[0071] Preferably, the length of the first sewing line will be displayed to the user while the first sewing line is generated.

[0072] It should be noted that the generated first sewing line has a direction, and the first starting point, the first end point and the generated first sewing line correspond to the same digital garment pattern.

[0073] S400: Repeat the above steps to determine a second starting point, a second end point and a second direction and generate a second sewing line.

[0074] Similarly, the generated second sewing line has a direction, and the second starting point, the second end point and the generated second sewing line correspond to the same digital clothing pattern; it should be noted that the digital clothing pattern corresponding to the first starting point, the first end point and the generated first sewing line and the digital clothing pattern corresponding to the second starting point, the second end point and the generated second sewing line are generally different digital clothing patterns, but in some cases they may also correspond to the same digital clothing pattern.

[0075] S500: Sewing the digital garment pattern piece based on the first sewing line and the second sewing line.

[0076] It should be noted that the dotted lines in the digital clothing pattern are reference lines, which can help users calibrate and confirm during the design and sewing process of the digital clothing pattern.

[0077] In a specific embodiment, the starting point of the first sewing line is the first starting point, the end point is the first end point, the direction of the first sewing line is the first direction, the starting point of the second sewing line is the second starting point, the end point is the second end point, and the direction of the second sewing line is the second direction. The method of sewing digital garment patterns based on two different sewing lines has been detailed in the prior art, and will not be described in detail in this embodiment.

[0078] To facilitate the user to select, preferably, when the first instruction is not received, or when the first direction is determined and the second instruction is not received, if there is a vertex of the digital clothing pattern within the fourth threshold range of the indicated coordinates, the indicated coordinates are aligned to the nearest vertex;

[0079] Similarly, if there is a cutting edge point of the digital garment pattern within the fifth threshold range of the indicated coordinates, the indicated coordinates are aligned to the cutting edge point; in a specific embodiment, the fourth threshold is equal to the fifth threshold.

[0080] It should be noted that the objects that can be operated by users in the digital clothing pattern are vertices, including but not limited to: Figure 2 , Figure 3 The turning points and corner points in the digital clothing pattern shown in the figure; the cutting edge points in the digital clothing pattern are special points on the digital clothing pattern. The cutting edge points are also called "knife edges". When producing physical clothing patterns based on the digital clothing patterns, the cutting edge points can play a positioning role in prompting users to perform cutting, sewing and other operations.

[0081] Specifically, please refer to Figure 5 , step S100 includes:

[0082] S110: After receiving the first instruction, searching whether there is a vertex of the digital clothing pattern within a second threshold range of the first coordinate point.

[0083] If the vertices of the digital garment pattern exist, step S120 is executed; if the vertices of the digital garment pattern do not exist, step S130 is executed.

[0084] S120: Determine the vertex closest to the first coordinate point as the first starting point.

[0085] S130: Searching whether there is a contour line of the digital garment pattern within a second threshold range of the first coordinate point.

[0086] It should be noted that the contour line is Figure 2-4 As shown in the figure, the contour lines are drawn on the digital garment pattern. The contour lines are used to define the boundaries and shapes of garment parts. By outlining the overall contours of garment parts, such as the front body, back body, sleeves, etc., users can refer to and operate them during the cutting and sewing process. In addition, the internal lines of the garment can also be reflected in the digital garment pattern as contour lines, including but not limited to the pleats of the garment, the axis of symmetry of the garment pattern, the stitches of the external contour lines, the stitches of the quilting lines of the down jacket, etc.

[0087] If the outline of the digital garment pattern exists, step S140 is executed; if the outline of the digital garment pattern does not exist, no response is made.

[0088] S140: Determine the vertex on the contour line that is closest to the first coordinate point as the first starting point.

[0089] Preferably, please refer to Figure 6 The step S200 of “determining the first direction based on the first line segment generated by connecting the current point of the indicated coordinates and the first starting point” includes:

[0090] S210: setting each contour line with the first starting point as an endpoint as a detection line, detecting the distance between the current point where the indicated coordinate is located and each detection line, and determining the detection line closest to the current point where the indicated coordinate is located as the direction line.

[0091] S220: Determine a direction extending from the first starting point to the other end of the direction line as a first direction.

[0092] Furthermore, to ensure the correctness of the first direction, the method further includes:

[0093] S230: After determining the first direction, prompting the user to determine whether the first direction is correct.

[0094] If the user determines that the first direction is incorrect, step S240 is executed; if the user determines that the first direction is correct, no change is made.

[0095] S240: Re-determine the reversed first direction as the first direction.

[0096] Therefore, when an error occurs in determining the first direction, the user can flexibly make adjustments.

[0097] Specifically, please refer to Figure 7 , the step S300 of “after receiving the second instruction, determining the first end point based on the second coordinate point where the indicated coordinates are currently located” includes:

[0098] S310: After receiving the second instruction, searching whether there is a vertex of the digital clothing pattern within a third threshold range of the second coordinate point.

[0099] If the vertices of the digital garment pattern exist, step S320 is executed; if the vertices of the digital garment pattern do not exist, step S330 is executed.

[0100] S320: Determine the vertex closest to the second coordinate point as the first end point.

[0101] S330: Determine the second coordinate point as the first end point.

[0102] In the actual application of the method, it is very likely that multiple edges of a garment pattern need to be sewn with other garment patterns, a garment pattern needs to be sewn with multiple garment patterns, and multiple garment patterns need to be sewn with multiple garment patterns. To meet the needs of these situations at the same time, please refer to Figure 8-9 , the method proposed in this embodiment also includes:

[0103] S340: After determining the first endpoint, if a third instruction is received, cancel the previous first endpoint, and extend the first direction based on the previous first direction and the most recently canceled first endpoint and the current location of the indicated coordinates.

[0104] It should be noted that the newly extended direction can be reversed according to step S230 and step S240, so that the newly extended direction and the original direction can point to the same point.

[0105] S350: After receiving the second instruction, redetermine the first end point based on the coordinate point where the indicated coordinates are currently located.

[0106] Preferably, each time after the first end point is re-determined, the length of the sewing line between the most recently cancelled first end point and the re-determined first end point is displayed to the user.

[0107] It should be noted that the methods of extending the first direction in step S340 and redetermining the first end point in step S350 are respectively the same as those in step S200 and step S300, and are not further described herein.

[0108] If the coordinate point where the indicated coordinates are currently located is not determined as the final first end point, step S340 is repeated; if the coordinate point where the indicated coordinates are currently located is determined as the final first end point, step S360 is executed.

[0109] S360: Generate a first sewing line based on the first starting point, the first end point and the first direction.

[0110] In this embodiment, the indicated coordinates include a mouse pointer, and the first instruction, the second instruction, and the third instruction include clicking the left mouse button; in other embodiments, the first instruction, the second instruction, and the third instruction may include but are not limited to clicking the right mouse button, clicking the mouse wheel button, clicking the side mouse button, entering specific characters, and the like.

[0111] Furthermore, after the first sewing line is generated, the user can still reselect the positions of the first starting point and the first end point and change the first direction to flexibly adjust the first sewing line.

[0112] It should be noted that the method of determining the first starting point, the first direction, the first end point and generating the first sewing line in the above method is also applicable to the method of determining the second starting point, the second direction, the second end point and generating the second sewing line, which will not be elaborated in this embodiment.

[0113] Example 2

[0114] This embodiment proposes a system for stitching digital clothing patterns, which is used to implement the method proposed in Embodiment 1. Fig.10 , the system comprising:

Similarly, the second sewing line generated has a direction, and the second starting point, the second end point and the generated second sewing line correspond to the same digital clothing pattern.

[0122] It should be noted that the digital clothing pattern corresponding to the first starting point, the first end point and the generated first sewing line and the digital clothing pattern corresponding to the second starting point, the second end point and the generated second sewing line are generally different digital clothing patterns, but in some cases they may correspond to the same digital clothing pattern.

[0123] In this embodiment, the indicated coordinates include a mouse pointer, and the first instruction and the second instruction include clicking the left mouse button; in other embodiments, the first instruction and the second instruction may include but are not limited to clicking the right mouse button, clicking the mouse wheel button, clicking the side mouse button, entering specific characters, etc.

[0124] To facilitate the user to select, the system proposed in this embodiment also includes:

[0125] The alignment module 26 is used to align the indicated coordinates to the nearest vertex if there is a vertex of the digital clothing pattern within the fourth threshold range of the indicated coordinates when the starting point determination module 21 does not receive the first instruction, or when the direction determination module 22 determines the first direction and the generation module 23 does not receive the second instruction; and / or, if there is a cutting edge point of the digital clothing pattern within the fifth threshold range of the indicated coordinates, align the indicated coordinates to the cutting edge point.

[0126] In a specific embodiment, the fourth threshold value is equal to the fifth threshold value.

[0127] Specifically, the starting point determination module 21 includes:

[0128] A first search unit 211 is used to search whether there is a vertex of the digital clothing pattern within a second threshold range of the first coordinate point after receiving the first instruction;

[0129] A first determining unit 212 is used to determine the vertex closest to the first coordinate point as the first starting point when there are vertices of the digital garment pattern;

[0130] The second searching unit 213 is used to search whether there is a contour line of the digital clothing pattern within a second threshold range of the first coordinate point when there is no vertex of the digital clothing pattern;

[0131] The second determining unit 214 is configured to determine, when there is a contour line of the digital garment pattern, a vertex on the contour line that is closest to the first coordinate point as a first starting point.

[0132] Preferably, the direction determination module 22 includes:

[0134] A direction determining unit 222, configured to determine a direction extending from the first starting point to the other end of the direction line as a first direction;

[0135] A prompting unit 223, configured to prompt a user to determine whether the first direction is correct after determining the first direction;

[0136] The reverse direction determining unit 224 is configured to redefine the reversed first direction as the first direction when the user determines that the first direction is incorrect.

[0137] Specifically, the generation module 23 includes:

[0138] The third search unit 231 is used to search whether there is a vertex of the digital clothing pattern within a third threshold range of the second coordinate point after receiving the second instruction;

[0140] The fourth determining unit 233 is configured to determine the second coordinate point as the first end point when there is no vertex of the digital garment pattern.

[0141] In the actual application of the method, it is likely that multiple edges of a garment pattern need to be sewn with other garment patterns, a garment pattern needs to be sewn with multiple garment patterns, and multiple garment patterns need to be sewn with multiple garment patterns. In order to meet the needs of these situations at the same time, the generation module 23 also includes:
