Description

Technical Field

[0001] The invention belongs to the technical field of clothing effect display, and in particular relates to a method and a device for optimizing clothing sewing effect. Background Art

[0002] In the current 3D clothing modeling and design technology, the technology of simulating and presenting the sewing process and effect of clothing in a virtual environment can increase the sense of reality and details in the 3D clothing design and display process, making the clothing model more realistic. Commonly used sewing technologies include light and dark map sewing, physical simulation sewing and carving tool sewing. However, these methods all have some shortcomings.

[0003] Light and dark map stitching achieves the stitching effect by applying light and dark maps around the stitching line. It can add shadow and highlight effects to make the stitching line look three-dimensional. The preset shadow can increase the rendering effect of the stitching. However, in fact, the three-dimensional mesh of the garment is still a plane and cannot truly reflect the light and shadow effects, which will lead to unrealistic production effects. The stitching line lacks three-dimensionality and cannot accurately express the real appearance and texture of the garment.

[0004] Physical simulation stitching uses physical simulation technology to simulate the stitching process of clothing, taking into account the stiffness, bending and stretching characteristics of the fabric, as well as the movement trajectory of the stitches and threads, and generates stitching effects by simulating the physical mechanical process. However, this method usually requires high computing resources and time, and may produce inaccurate results for complex clothing structures.

[0005] Sculpting tool stitching uses sculpting tools in 3D modeling software such as Zbrush to manually add wrinkles and bump effects to simulate the deformation of the cloth around the seams. This method requires the modeler to manually add additional wrinkles and bump effects using the sculpting brush tool to represent the sewing lines, which requires a high level of technical ability from the modeler and also takes a lot of time. Summary of the invention

[0006] In order to overcome the defects of the prior art, the present invention proposes a method for optimizing the sewing effect of clothing, the method comprising:

[0007] Confirm the seaming surfaces of the two garment pattern pieces that need to be sewn;

[0008] A new rendering grid in the form of a raised portion is superimposed on the seamed end of at least one of the garment panels based on a preset height and a preset width; the vertical height difference between the highest point of the raised portion and the seamed end of the garment panel where the raised portion is located after the superposition is the same as the preset height, and the horizontal distance between the highest point of the raised portion and the seamed end of the garment panel where the raised portion is located is the same as the preset width;

[0009] The two pieces of the garment patterns are sewn together so that when the garment patterns are displayed, the light and shadow effects at the sewing points of the garment patterns are optimized through the newly created rendering grid.

[0010] Specifically, when a newly created rendering grid in the form of a raised portion is superimposed only on the sewn end of one piece of the garment pattern, the “newly created rendering grid in the form of a raised portion is superimposed on the sewn end of at least one piece of the garment pattern based on the preset height and the preset width” includes:

[0011] Detecting the folding condition of the sewn end of the garment pattern piece on which the newly created rendering grid needs to be superimposed;

[0012] If both sides of the sewing end of the garment pattern are folded, newly-created rendering grids in the form of the raised portion are respectively superimposed on both sides of the sewing end of the garment pattern based on the preset height and the preset width;

[0013] If one side of the sewing end of the garment pattern is folded, a newly created rendering grid in the form of the raised portion is superimposed on the folded side of the sewing end of the garment pattern based on the preset height and the preset width.

[0014] Furthermore, the method further comprises:

[0015] When the newly created rendering grids in the form of raised portions are superimposed on the sewing ends of the two garment patterns, the newly created rendering grids on the two garment patterns are set on the same surface of the sewing ends, and the two newly created rendering grids do not contact each other after the garment patterns are sewn.

[0016] Preferably, the method further comprises:

[0017] If the preset width value is not greater than the preset width threshold, the newly created rendering grid in the form of the raised portion superimposed on the stitched end of the garment pattern piece has only one raised corner; the vertex of the raised corner is the highest point of the raised portion:

[0018] If the preset width value is greater than the preset width threshold, the newly created rendering grid in the form of the raised portion superimposed on the sewing end of the clothing pattern has multiple raised angles, and the angle of each raised angle is within the preset angle threshold; the height of the raised angle farther away from the sewing end is higher, and the vertex of the raised angle with the farthest horizontal distance from the sewing end is the highest point of the raised portion.

[0019] Specifically, the “newly-created rendering grid with a raised portion superimposed on the seamed end of at least one of the garment patterns based on a preset height and a preset width” also includes:

[0020] Meshing the clothing pattern to obtain an original mesh;

[0021] An original grid is selected at the seaming end of the garment pattern based on the preset width, and the selected original grid is superimposed based on the preset height, thereby generating the newly created rendering grid in the shape of a raised portion, and rendering the garment pattern based on the newly created rendering grid.

[0022] Furthermore, the method further comprises:

[0023] When simulating the garment pattern piece, the garment pattern piece is simulated based on the original grid.

[0024] Preferably, the preset height is determined based on the thickness of the garment pattern.

[0025] The present invention also proposes a method for optimizing the sewing effect of clothing, which is used to implement the method described above, and the device comprises:

[0026] A confirmation module is used to confirm the sewing surfaces of two garment patterns that need to be sewn;

[0027] A superposition module is used to superimpose a newly created rendering grid in the form of a raised portion on the stitched end of at least one of the garment panels based on a preset height and a preset width; after the superposition, the vertical height difference between the highest point of the raised portion and the stitched end of the garment panel where the raised portion is located is the same as the preset height, and the horizontal distance between the highest point of the raised portion and the stitched end on the garment panel where the raised portion is located is the same as the preset width;

[0028] The stitching module is used to stitch the two garment patterns together so as to optimize the light and shadow effects at the stitching points of the garment patterns through the newly created rendering grid when displaying the garment patterns.

[0029] Specifically, the stitching module includes:

[0030] A detection unit, used for detecting the folding condition of the sewn end of the garment pattern piece on which the newly created rendering grid needs to be superimposed;

[0031] A first superimposing unit is used for superimposing the newly created rendering grid in the form of the convex portion on the two sides of the sewing end of the garment pattern piece based on the preset height and the preset width respectively when the two sides of the sewing end of the garment pattern piece are folded;

[0032] The second superimposing unit is used for superimposing a newly created rendering grid in the form of the raised portion on the folded side of the sewing end of the garment plate based on the preset height and the preset width when one side of the sewing end of the garment plate is folded.

[0033] Specifically, the superposition module includes:

[0034] A gridding unit, used for gridding the garment pattern to obtain an original grid;

[0035] A generating unit, configured to select an original mesh at a sewing end of the garment pattern piece based on the preset width, and to superimpose the selected original mesh based on the preset height, thereby generating the newly rendered mesh in the form of a raised portion;

[0036] The device also includes:

[0037] A rendering module, used for rendering the garment pattern based on the newly created rendering grid;

[0038] A simulation module is used to simulate the garment pattern based on the original grid.

[0039] The present invention has at least the following beneficial effects:

[0040] This solution adjusts the clothing pattern through preset parameters and optimizes it. The method is simple and easy, can save computing resources and time, and has the advantages of strong controllability and wide application range. It improves the light and shadow effects of the seams of clothing, enhances the realism, three-dimensional sense and texture of clothing, and can also improve the display effect of clothing, bringing more advantages to design and sales;

[0041] Furthermore, the present scheme can detect the preset parameters and folding conditions of the seamed ends of the clothing pattern, and superimpose raised parts according to different situations, further enhancing the flexibility and applicability of the method. By gridding the clothing pattern and adjusting and moving the grid pattern at the position where the raised parts exist, the light and shadow effects of the raised parts are taken into consideration during the rendering process, which can ensure that the raised parts obtain better rendering effects, improve the overall visual quality, and make rendering and simulation independent of each other, so that the processing of the clothing pattern due to rendering performed by this scheme will not affect the actual application process of the clothing pattern.

[0042] Therefore, the present invention proposes a method and device for optimizing the stitching effect of clothing. This scheme realizes the control and optimization of the topological structure of the stitching through preset values. The user can flexibly adjust the stitching effect to meet the design requirements by changing the preset values, and make the stitching of the clothing pattern present a more realistic and natural light and shadow effect when displayed, thereby enhancing the realism, three-dimensional sense and texture of the clothing.

[0063] Example 1

[0064] This embodiment proposes a method for optimizing the sewing effect of clothing. Figure 1 , the method comprising:

[0065] S100: Confirm the sewing surfaces of two garment pattern pieces that need to be sewn.

[0066] It should be noted that the function of step S100 is to confirm the surface of the garment pattern piece that needs to be sewn, so as to make the sewing surfaces of the two garment pattern pieces that need to be sewn flush;

[0067] Suturing includes two sewing methods: single-sided sewing and double-sided sewing. Single-sided sewing only requires the sewing surfaces of the two clothing pieces to be displayed to be flush, while double-sided sewing requires both sides of the two clothing pieces to be flush. Therefore, when using the double-sided sewing method, step S100 also requires adjusting the two clothing pieces to the same thickness so that the sewing surfaces of the two clothing pieces can achieve a flush effect.

[0068] S200: Preset a height and a width, and based on the preset height and the preset width, superimpose a newly created rendering grid in the form of a raised portion on a sewing end of at least one garment pattern piece.

[0069] Preferably, the preset height is determined based on the thickness of the garment pattern; illustratively, the preset height may be made the same as the thickness of the garment pattern, or may be made twice the thickness of the garment pattern.

[0070] It should be noted that the vertical height difference between the highest point of the raised portion after superposition and the stitching end of the clothing piece where the raised portion is located is the same as the preset height, and the horizontal distance between the highest point of the raised portion and the stitching end on the clothing piece where the raised portion is located is the same as the preset width.

[0071] S300: Stitch two garment patterns together to optimize the lighting and shadow effects at the seam of the garment patterns by creating a new render grid when displaying the garment patterns.

[0072] Specifically, see Figure 2-4 When newly created rendering meshes in the form of raised parts are superimposed on the seamed ends of two clothing patterns, the newly created rendering meshes on the two clothing patterns are set on the same side of the seamed ends, and the two newly created rendering meshes do not contact each other after the clothing patterns are sewn together, so that when the clothing patterns are displayed, the seam of the two clothing patterns shows an inward concave effect.

[0073] Preferably, if the preset width value is not greater than the preset width threshold, the newly created rendering grid in the form of the raised portion superimposed on the stitched end of the garment pattern piece has only one raised corner; the vertex of the raised corner is the highest point of the raised portion:

[0074] If the preset width value is greater than the preset width threshold, the newly created rendering grid in the form of the raised portion superimposed on the stitched end of the garment pattern has multiple raised angles, and the angle of each raised angle is within the preset angle threshold; the height of the raised angle farther away from the stitched end is higher, and the vertex of the raised angle with the farthest horizontal distance from the stitched end is the highest point of the raised portion.

[0075] Exemplarily, when the value of the preset width w is not greater than the preset width threshold, when the raised portion has only one raised angle, the angle of the raised angle is small, and the raised portion forms a triangular edge on the surface of the garment pattern. At this time, the angle between the raised portion and the sewing end of the garment pattern is large, so there will be a more obvious height difference effect when displaying the garment pattern.

[0076] When the value of the preset width w′ is greater than the preset width threshold, if the raised portion has only one raised angle, the angle of the raised angle is larger. At this time, the angle between the raised portion and the sewing end of the clothing pattern is smaller, which will weaken the height difference effect when displaying the clothing pattern. In this embodiment, the angle between the raised portion and the sewing end of the clothing pattern is increased by adding a raised angle to ensure that a better height difference effect can be achieved when displaying the clothing pattern.

[0077] In addition, the stitching between the folded garment panel and the unfolded garment panel can be realized by applying the situation in which the convex portion is superimposed on the stitching end of a garment panel in the present solution, see Figure 5-7 The “creating a new rendering grid with a raised portion superimposed on the stitching end of at least one garment pattern piece based on a preset height and a preset width” in step S200 includes:

[0078] S210: Detecting the folding condition of the sewing end of the garment pattern piece that needs to be superimposed with the newly created rendering mesh.

[0079] If both sides of the sewing end of the garment pattern piece are folded, step S220 is executed; if one side of the sewing end of the garment pattern piece is folded, step S230 is executed.

[0080] S220: Newly rendered meshes in the form of raised portions are superimposed on both sides of the sewn end of the garment pattern piece based on the preset height and the preset width.

[0081] It should be noted that when the two sides of the seamed end of a clothing pattern are folded, the raised ends of the newly created rendering grids superimposed on both sides of the seamed end of the clothing pattern can be set at the center of the seamed end of the clothing pattern, and the two newly created rendering grids do not contact each other after the clothing pattern is sewn, thereby simulating a real folding effect.

[0082] S230: creating a new rendering grid with a raised portion superimposed on a folded side of the sewn end of the garment pattern piece based on a preset height and a preset width.

[0083] It should be noted that the folding of the garment pattern refers to folding the fabric at the edge of the garment pattern inward so that the inner fabric overlaps with the outer fabric to form a seam edge for sewing, thereby achieving the effect of hiding the edge, enhancing the firmness of the sewing, and providing a neater and more beautiful appearance;

[0084] Specifically, when both sides of the sewing end of the garment pattern are folded, the fabric at the sewing end is folded inward twice, so that both sides of the fabric are folded inward; when one side of the sewing end of the garment pattern is folded, the fabric at the sewing end is folded inward once, so that one side of the fabric is folded inward;

[0085] By folding the seam ends, better seam effects and quality can be achieved, ensuring the appearance and comfort of the garment.

[0086] Specifically, see Figure 8 , step S200 further includes:

[0087] S240: Meshing the clothing pattern to obtain an original mesh.

[0088] S250: selecting an original mesh at a stitching end of the garment pattern based on a preset width, and superimposing the selected original mesh based on a preset height, thereby generating a new rendering mesh of a raised portion, and rendering the garment pattern based on the new rendering mesh.

[0089] Furthermore, the method for optimizing the sewing effect of clothing proposed in this embodiment simulates the clothing pattern based on the original grid when simulating the clothing pattern. Therefore, this scheme can make rendering and simulation independent of each other, and the processing of the clothing pattern due to rendering in the scheme will not affect the actual application process of the clothing pattern.

[0090] Example 2

[0091] This embodiment proposes a device for optimizing the sewing effect of clothing, which is used to implement the method proposed in embodiment 1. Fig. 9 , the device comprises:

[0092] A confirmation module 10 is used to confirm the sewing surfaces of two garment patterns that need to be sewn;

[0093] An overlay module 20, configured to overlay a newly created rendering grid in the form of a raised portion on a stitched end of at least one garment pattern piece based on a preset height and a preset width;

[0094] The stitching module 30 is used to stitch two garment patterns together so as to optimize the light and shadow effects at the stitching points of the garment patterns by creating a new rendering grid when displaying the garment patterns.

[0095] It should be noted that the vertical height difference between the highest point of the raised portion and the stitching end of the clothing piece where the raised portion is located after superposition by the superposition module 20 is the same as the preset height, and the horizontal distance between the highest point of the raised portion and the stitching end on the clothing piece where the raised portion is located is the same as the preset width.

[0096] Specifically, the stitching module 20 includes:

[0097] A detection unit 21, used to detect the folding condition of the sewn end of the garment pattern piece to be superimposed with the newly created rendering grid;

[0098] A first superimposing unit 22, configured to superimpose newly created rendering grids in the form of raised portions on both sides of the sewing end of the garment pattern piece based on a preset height and a preset width when both sides of the sewing end of the garment pattern piece are folded;

[0099] The second superimposing unit 23 is used for superimposing a newly created rendering grid in the form of a raised portion on the folded side of the sewing end of the garment pattern piece based on a preset height and a preset width when one side of the sewing end of the garment pattern piece is folded.

[0100] Specifically, the stitching module 20 also includes:

[0101] A meshing unit 24 is used to mesh the garment pattern to obtain an original mesh;

[0102] The generating unit 25 is used to select the original mesh at the sewing end of the garment pattern based on the preset width, and to superimpose the selected original mesh based on the preset height, so as to generate a new rendering mesh of the raised part shape.

[0103] Furthermore, the device proposed in this embodiment also includes:

[0104] A rendering module 31, used for rendering the garment pattern based on the newly created rendering grid;

[0105] The simulation module 32 is used to simulate the garment pattern based on the original grid.

[0106] In summary, the present invention proposes a method and device for optimizing the stitching effect of clothing. This scheme realizes the control and optimization of the topological structure of the seams through preset numerical values. The user can flexibly adjust the stitching effect to meet the design requirements by changing the preset numerical values, and make the seams of the clothing pieces present more realistic and natural light and shadow effects when displayed, thereby enhancing the realism, three-dimensional sense and texture of the clothing.

[0107] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
