Description

Technical Field

[0001] This invention relates to the field of clothing design technology, specifically to a digital clothing embroidery pattern design system and its virtual imaging device for finished garments. Background Technology

[0002] Clothing embroidery pattern design refers to the application of embroidery patterns to clothing designs, showcasing the designer's creative concepts and style. Embroidery patterns can be images or combinations of geometric patterns, text, plants, and other elements. In clothing embroidery pattern design, designers draw embroidery patterns on garments so that consumers can better understand the design concept and enhance the garment's aesthetic appeal.

[0003] Virtual imaging can convert digital information into realistic images. It typically uses computer graphics to simulate and render images, and employs various algorithms and techniques to mimic real-world optical effects.

[0004] Currently, designers cannot see the finished product beforehand during the garment embroidery pattern design process; they can only imagine the actual finished effect based on the designer's hand-drawn sketches, which requires a high level of professional skill. Applying virtual imaging technology to garment embroidery pattern design would greatly improve the designer's work and presentation. Summary of the Invention

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of the present invention will now be described.

[0029] Please refer to the following examples. Figure 1 A digital garment embroidery pattern design system includes a garment style module, a basic pattern library, a pattern retrieval module, a pattern overlay module, an effect rendering module, and an effect display module. The garment scanning module matches garment styles to be embroidered, thereby acquiring digital data of the garment's three-dimensional style. The basic pattern library stores a large amount of digital information on embroidery patterns. The pattern retrieval module quickly finds the required patterns within the basic pattern library. The pattern overlay module allows designers to digitally overlay and combine selected patterns onto a three-dimensional digital model of the garment. The effect rendering module renders the completed design into a finished product image using a renderer. The effect display module displays the rendered finished product effect on a virtual garment imaging device.

[0030] The garment style module includes a regular style database, a style modification unit, and a 3D scanning unit. The regular style database stores a large amount of 3D digital information of regular styles, which designers can select and call. The style modification unit is used to modify the 3D model of the selected regular style as needed to form the required modified model. The 3D scanning unit is used to scan the garment of special design style through the 3D capture device on the garment virtual imaging device, and then generate the 3D model of the special design style.

[0031] The embroidery pattern information stored in the basic pattern library includes pattern outlines, embroidery techniques, and three-dimensional modeling data.

[0032] The pattern overlay module includes a stitch rejection module. During the design process, when designers overlap multiple embroidery patterns, the stitches at the overlapping points of the patterns are judged. When the stitches of multiple embroidery patterns affect each other, the overlapping points are marked in red, and the designers are prompted to reject the stitches at that point.

[0033] The effect rendering module includes a multi-angle rendering template unit, a 3D model effect unit, and a partial detail unit. The multi-angle rendering template unit is used to render the completed design draft into a complete set of display renderings from multiple fixed angles. The 3D model effect unit is used to render the completed design draft into a 3D stereoscopic effect, which can be used for 3D operable display, virtual wear display, and metaverse dynamic wear display. The partial detail unit is used to zoom in on key design elements and render detailed renderings of those elements.

[0034] The effect display module includes a static image display unit, a 3D effect display unit, and a virtual clothing display unit. The static image display unit is used to project the rendered complete set of display effect images and detailed effect images onto the monitor for display. The 3D effect display unit is used to project the 3D effect onto the touch screen for display and allows 3D operation and viewing. The virtual clothing display unit is used to project the 3D effect onto the garment virtual imaging device for virtual clothing display.

[0035] An example is a virtual imaging device for finished garments in a digital garment embroidery pattern design system. Please refer to the following example. Figure 2-4 The system includes a display component 1, a main unit 2 at one end of the display component 1, a single lens 3 on the top surface of the main unit 2 near the display component 1, and a dark glass 4 on one side of the single lens 3 and above the display component 1. The top surfaces of the main unit 2 and the display component 1 are both located on the bottom surface of a dark box 5. A visual tracking mechanism 6 is located at one end of the interior of the dark box 5, and an effect display platform 7 is located at the other end of the display component 1. A motion capture mechanism 8 is located above the effect display platform 7. In this design, an interactive user wears the garment to be designed on the effect display platform 7. The motion capture mechanism 8 captures the interactive user's movements, and the visual tracking mechanism 6 follows the interactive user's head position to display the design content on the display component 1. The dark glass 4 refracts the displayed content onto the effect display platform 7, allowing the interactive user to see the design content overlap with their own image on the single lens 3, achieving a virtual imaging effect.

[0036] Please refer to the following examples. Figure 5The display component 1 includes a display screen 11, which is located on the bottom of the display box 12. The top of the display box 12 is provided with a light-blocking grille 13, which is perpendicular to the direction of the dark box 5. This design allows the display screen 11 to display mirrored design content, which is refracted into a positive image by the dark glass 4. The light-blocking grille 13 prevents the interactive personnel from directly seeing the display screen 11 at the bottom of the display box 12.

[0037] Please refer to the following examples. Figure 6 The visual following mechanism 6 includes a four-axis robotic arm 61. The fixed end of the four-axis robotic arm 61 is located inside one end of the dark box 5, and the free end of the four-axis robotic arm 61 is equipped with a visual following depth camera 62. This design controls the visual following depth camera 62 to always follow the facial position of the interactive user through the four-axis robotic arm 61, thereby adjusting the position of the content on the display screen 11 to ensure that the content displayed in the interactive user's field of vision always overlaps with the image on the single lens 3.

[0038] Please refer to the following examples. Figure 7-8 The motion capture mechanism 8 includes a capture frame 81, with three-dimensional capture depth cameras 82 respectively installed at the four corners of the inner top surface of the capture frame 81. All three-dimensional capture depth cameras 82 are aligned with the inner center point of the capture frame 81. This design can be used for three-dimensional scanning of unconventional garment styles before design. During interaction, the movements of the interacting person are accurately captured by multiple three-dimensional capture depth cameras 82. Through the virtual wearing display unit, the design content is controlled to match the movements of the interacting person, thus achieving motion matching.

[0039] Operating Principle: First, the designer selects a suitable design style from the regular style database in the garment style module. If necessary, modifications can be made to the regular style using the style modification unit. For non-regular styles, the garment with the design is worn on a mannequin and placed on the effect display platform 7. The motion capture mechanism 8 performs a 3D scan of the non-regular style garment to obtain a 3D digital model. Then, the pattern retrieval module selects the required pattern from the basic pattern library and places it on the digital model of the garment with the design for design. The pattern overlay module judges the stitching at the overlapping areas of the patterns. When the stitching of multiple embroidery patterns affects each other, the overlapping area is marked in red, and the designer is notified of the stitching discrepancy. After the design is completed, the effect rendering module renders the completed design from multiple fixed angles to create a set of display effect images and designs. Key detail renderings and 3D stereoscopic models are displayed on a monitor using static image display units. The 3D stereoscopic models can be displayed on a touchscreen using stereoscopic effect display units, allowing for 3D stereoscopic viewing. The 3D stereoscopic models can also be projected onto a virtual garment imaging device using a virtual dressing display unit for virtual dressing demonstration. The virtual garment imaging device uses a motion capture mechanism 8 to capture the user's movements while wearing the designed garment on the effect display platform 7. A visual tracking mechanism 6 follows the user's head position, displaying the design content on the display component 1. The dark glass 4 refracts the displayed content onto the effect display platform 7, allowing the user to see the design content overlap with their own image on a single lens 3, achieving a virtual imaging effect.
