[0042] In order to enable those skilled in the art to better understand the technical solution of the present invention and to be able to implement it, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0043] Example

[0044] The present invention provides a Yao ethnic clothing design learning system, which specifically includes a cognitive module, a material management module, a practical skills module, a teaching module and an AI processing module. Figure 1 shown.

[0045] The cognitive module uses pictures and text to introduce users to the historical background, cultural significance, and place of Yao clothing within China's diverse culture. The system provides a wealth of historical documentation and academic research to help users understand the development and evolution of Yao clothing.

[0046] The material management module is used to generate the Yao ethnic clothing materials and three-dimensional character models required for the design and store them in the database. The Yao ethnic clothing materials specifically include clothing cutting materials, color material information, fabric material information and clothing pattern materials.

[0047] The 3D character models include one male and one female, and are modeled at a 1:1 scale according to the character model standards commonly used in clothing design. The character models are modeled and processed in 3D Max. The steps involved in creating a highly realistic 3D character model are as follows:

[0048] (1) Import a human body reference image, such as a photo or hand-drawn sketch, to ensure the model's proportions and form are accurate. Use 3D Max's modeling tools, such as "sphere" and "cuboid," to begin building the basic shape of the character, usually starting with large blocks such as the head, chest, pelvis, and limbs.

[0049] (2) Refine the mesh, add vertices and edges to increase the level of detail of the model, and use sculpting tools such as "Move", "Scale" and "Smooth" to shape the character's facial features, muscle and fat distribution.

[0050] (3) Expand the surface of the 3D model into 2D to prepare for texture mapping. Ensure that the UV layout is accurate to avoid distortion and deformation during texture mapping. Apply skin texture mapping to the character model, including color, roughness, and normal maps to simulate the visual effect of real skin. Add detailed textures such as eyes, teeth, and hair to enhance the realism of the model.

[0051] (4) Create materials in 3Dmax, such as skin, clothing, accessories, etc., and assign corresponding texture maps, set the scene lighting to simulate natural lighting or specific environmental lighting, use the classic three-point lighting method to illuminate the scene, including main light source, auxiliary light source and backlight source, improve shadow quality, use ray tracing shadows or advanced shadow maps, render clothing models, character models and other elements separately, and then synthesize them in post-production synthesis software to obtain better control and optimization effects, and perform rendering tests, such as Figure 6 shown.

[0052] The practical skills module includes two parts: clothing drawing skills and clothing structure design skills. Figure 2As shown, both modules use the game level system to design various styles of clothing in turn. In the clothing drawing skill module, users will go through the whole process from obtaining human body dimensions to drawing clothing renderings, including key links such as plane structure design, color and fabric selection, and pattern matching. The clothing structure design skill module focuses more on the three-dimensional structure of clothing, covering all steps from paper pattern drawing to sewing and production. Among them, clothing drawing skills include obtaining human body dimensions, clothing plane structure drawing, color matching adjustment, fabric and attribute adjustment, clothing pattern matching, clothing display, drawing structure diagram and effect Figure 7 The clothing structure design skills include obtaining human body dimensions, comprehensive clothing structure, clothing pattern drawing, clothing sewing and production, clothing display, drawing structure diagrams and effects. Figure 6 Among them, the clothing plane structure diagram is as follows Figure 7 As shown, the clothing is displayed as Figure 11 As shown; draw the structure diagram and effect diagram as shown Figure 12 As shown; clothing pattern drawing as Figure 13 As shown; the effect of clothing sewing is as follows Figure 14 The main functions of each link in the practical skills module are as follows:

[0053] (1) Obtaining human body dimensions: Use a relational database (such as MySQL) to store preset dimension data of male and female models, including height, chest circumference, waist circumference, and other information, and organize the data in a table format. The front end sends an HTTP request to a specific interface of the back end server. The server queries the corresponding human model and dimension data from the database and returns it to the front end in JSON format. After receiving the data, the front end displays the human model and dimension information on the interface, such as Figure 3 shown.

[0054] (2) Clothing planar structure diagram: Use 3D modeling software to create a 3D model of the clothing piece and export it to a specific format (such as OBJ or FBX). On the back end, use WebGL technology to load the 3D model into the front end page and associate it with the 2D clothing piece. When the front end clicks on the 2D clothing piece, an event is triggered through JavaScript code, and a request is sent to the back end to obtain the corresponding 3D model data. After receiving the request, the back end reads the 3D model data from the file system or database and returns it to the front end. The front end uses the WebGL API to render the 3D model on the page and implement interactive functions such as rotation and scaling.

[0055] (3) Color matching adjustment, use a color management system (such as Adobe Color) to define and store color data. In the back end, use a database or data structure (such as a hash table) to record the colors recently used by the user. After the front end clicks on the cutting area on the three-dimensional model of the clothing, a color adjustment request is sent to the back end through JavaScript. The back end updates the color data according to the request and returns the updated color value to the front end. The front end uses the received color value to update the color display of the model, such as Figure 8 shown.

[0056] (4) Fabric and attribute adjustment, store fabric information in the database, including fabric name, material attributes, etc. Associate fabric with garment cutting area so that it can be correctly applied to the corresponding cutting area when selecting fabric. After the front end clicks on the cutting area on the three-dimensional model of the garment, it sends a fabric selection request to the back end. The back end queries the database according to the request, obtains the corresponding fabric information, and returns the fabric effect data (such as material texture image) to the front end. The front end uses this data to update the display effect of the cutting area, such as Figure 9 shown.

[0057] (5) Clothing pattern matching: Store patterns of different categories in a database or file system and use identifiers or tags for classification management. In the front end, use JavaScript and CSS to implement the drag and drop function of patterns. When the front end selects a pattern from the left menu bar and drags it to the three-dimensional model of clothing, it sends a pattern matching request to the back end. The back end updates the pattern data according to the request and returns information such as the position, size and direction of the pattern to the front end. The front end displays the pattern effect on the model based on this information and provides adjustment functions in the property window, such as Figure 10 shown.

[0058] (6) Use the image storage service to store screenshot data. In the backend, use the file upload and download interface to manage the storage and retrieval of screenshots. When the frontend clicks the "Screenshot" button, a third-party library is used to perform the screenshot operation and send the screenshot data to the backend. The backend stores the screenshot data in the image storage service and returns the storage path or identifier. When the "Gallery" button is clicked, the frontend sends a request to obtain the path or identifier of the historical screenshots. The backend reads the screenshot data from the image storage service and returns it to the frontend for display. When the "Delete" button is clicked, the frontend sends a deletion request, and the backend deletes the specified screenshot data from the image storage service according to the request.

[0059] (7) Draw structural diagrams and renderings, and use the file storage system to store the structural diagram and rendering files uploaded by students. In the back-end, use the file upload and management interface to handle file storage and retrieval. Use the drawing tools to draw offline according to the topic given by the system, and then upload the drawn structural diagram and rendering files to the front-end. The front-end sends the file to the back-end through a request, and the back-end stores the file in the file storage system and records relevant information (such as student ID, experiment name, etc.). Students can view the uploaded works in the "Personal Center" and submit them.

[0060] (8) Clothing sewing and production uses mathematical calculations and geometric algorithms to achieve the correct placement of pieces on the mannequin. On the back end, based on the shape and position information of the pieces, the collision and overlap between the pieces are calculated to determine whether the placement is correct. When the front end clicks on a two-dimensional clothing piece in the pattern library and places it on the mannequin, the piece position information is sent to the back end. The back end calculates the placement of the piece based on the algorithm and returns the judgment result to the front end for prompting. If the placement is correct, the front end displays the corresponding prompt information; if the placement is incorrect, the front end prompts the user to readjust the position of the piece.

[0061] Inspect the imported pattern in the viewport to ensure there are no damaged or missing parts. Use modifiers to adjust the pattern to ensure it meets the design requirements. Use the Subdivision or Sculpting tools to add details such as wrinkles and seams. Use high-resolution texture maps to increase the detail and realism of the rendered results. Adjust material properties such as glossiness, transparency, and reflection to more realistically simulate the garment material.

[0062] On the backend, file upload and download interfaces are used to manage the storage and retrieval of screenshots. When the frontend clicks the "Screenshot" button, a third-party library is used to take a screenshot and the screenshot data is sent to the backend. The backend stores the screenshot data in the image storage service and returns the storage path or identifier. When the "Gallery" button is clicked, the frontend sends a request to obtain the path or identifier of historical screenshots. The backend reads the screenshot data from the image storage service and returns it to the frontend for display. When the "Delete" button is clicked, the frontend sends a deletion request, and the backend deletes the specified screenshot data from the image storage service according to the request.

[0063] The teaching module stores the questions and correct answers set by the teacher in the database and organizes the data in a table format. After the front-end student completes the question, he clicks the submit button to send the answer data to the back-end. After receiving the answer data, the back-end compares it with the correct answer in the database, determines the student's answer result, and returns the correct answer and judgment result to the front-end for display. Use the file storage system to store the structural diagram and rendering file uploaded by the student. In the back-end, use the file upload and management interface to handle the storage and retrieval of files. Use the drawing tool to draw offline according to the questions given by the system, and then upload the drawn structural diagram and rendering file to the front-end. The front-end sends the file to the back-end through a request. The back-end stores the file in the file storage system and records the relevant information (such as student ID, experiment name, etc.). Students can view the uploaded works in the "Personal Center" and submit them.

[0064] AI processing modules such as Figure 5 As shown, the system uses microphones and other audio input devices to capture user voice commands, ensuring that the device can adapt to different environmental noise levels to improve the clarity of the voice signal. A noise reduction algorithm is applied to reduce background noise and improve the quality of the voice signal. An acoustic model is used to convert the audio signal into phonemes or words. A language model is then combined to predict the probability of word sequences. Natural language processing (NLP) is then used to analyze the user's input text to determine intent. Key information, such as zoom in, zoom out, and rotation, is extracted from the text. Based on the user input and system status, the next action is determined, converting the identified intent into an executable command. To enhance the human-computer interaction experience in clothing design, the system also supports bilingual switching between Chinese and English, providing convenience for learners from different language backgrounds. This helps promote Yao culture globally and enhances the international influence of the ethnic culture.

[0065] The present invention builds a system based on the MVC design pattern, including controllers, views and models, such as Figure 4 As shown, the controller is the medium for interaction between the view and the model. The view is updated by the user's operation of the controller; after the controller is updated, the model interacts with the controller in the form of notifications.

[0066] The present invention has the following beneficial effects: The Yao ethnic clothing design AI game practice skill learning system is an innovative education platform that combines virtual digital human technology, aiming to spread and teach Yao ethnic clothing design through digital means.

[0067] Through character modeling, data-driven development, and voice dialogue synthesis, users are shown how clothing will look and feel when worn and how it will be made. Existing digital tools and software are unable to fully simulate the actual clothing design and production process, limiting learners' understanding of the entire clothing design process. This invention uses three-dimensional modeling and simulation technology to fully recreate the entire process of clothing design, production, and display, allowing learners to experience the real design process in a virtual environment. By presenting the rich styles, patterns, and structures of Yao clothing to users in an interactive format, it not only protects the original appearance of the ethnic culture but also encourages innovative design, giving traditional art new vitality with the help of modern technology.

[0068] Existing digital tools and software cannot fully simulate the actual clothing design and production process, limiting learners' understanding of the entire apparel design process. The system of this invention combines cognitive modules with practical skills modules. After completing theoretical knowledge learning, users can immediately apply what they have learned in practical operations. This interactive learning method greatly enhances users' learning interest and practical skills. The entire process of clothing design, production, and display is fully reproduced, allowing learners to experience the real design process in a virtual environment.

[0069] Using AI technology, the system can recognize user operations and provide real-time feedback. Traditional teaching methods and basic digital tools lack interactivity and cannot provide opportunities for practical operations, which makes it difficult for learners to deeply understand and master the design and production skills of Yao costumes. By integrating advanced artificial intelligence technology and three-dimensional modeling, the present invention provides a highly interactive and practical learning environment, enabling learners to design and make clothing in a virtual environment, thereby enhancing the learning experience and skill acquisition. This intelligent interactive method not only improves learning efficiency, but also provides users with a more natural and immersive learning experience. It can also track and evaluate learners' progress and achievements in real time through teaching modules, provide timely feedback and guidance, thereby improving learning efficiency and teaching effectiveness,

[0070] Through this system, learners in remote areas can also access high-quality educational resources, narrowing the gap in educational resources between urban and rural areas and promoting educational equity. Therefore, the Yao ethnic clothing design AI game practical skills learning system is not only an educational tool, but also a bridge connecting the past and the future, tradition and modernity, and the local and international. It presents the essence of Yao ethnic clothing culture to the world in a brand new way, opening up a new path for the inheritance and development of ethnic culture.

[0071] Through personalized level design and card collection, the system inspires the user's spirit of exploration and learning motivation, making the learning process more personalized and fulfilling. The system also incorporates a storyline, with each step aligning with the storyline to provide inspiration for clothing design. This fully leverages the software's fun and flexibility, adding a variety of elements to enrich the learning process.

[0072] Each module in the aforementioned Yao ethnic clothing design learning system can be implemented in whole or in part through software, hardware, or a combination thereof. Each module can be embedded in or independent of a processor in a computer device in the form of hardware, or can be stored in a memory in the computer device in the form of software, so that the processor can call and execute the corresponding operations of each module.
