Description

Technical Field

[0001] This invention relates to the field of customized clothing technology, specifically to a personalized pattern automatic generation system based on 3D scanning. Background Technology

[0002] Custom-made clothing refers to garments tailored and made individually according to a person's size, body shape, preferences, and needs. It's not just about altering sleeve lengths; it's a comprehensive, personalized service encompassing fabric selection, style design, and meticulous craftsmanship. The most crucial aspect of custom-made clothing is pattern design based on the client's body characteristics. Early methods involved manual measurement to determine data before pattern design. With advancements in technology, 3D scanning is now used to create personalized patterns. The primary equipment employed is a 3D human body scanner, which offers significantly higher accuracy than manual measurements. This scanner compares and categorizes the user's body shape against a vast database (e.g., apple, pear, hourglass, rectangular; or even finer shapes). (Segments such as upright posture, hunchback posture, etc.) provide a basis for subsequent selection or adjustment of the basic pattern. Then, based on customer needs, a personalized pattern is generated. Currently, most 3D human body scanners are based on depth imaging principles. For example, Chinese utility model patent CN209332062U discloses a 3D human body scanner, including a scanning device, a lifting device, and a translation device. The scanning device is mounted on the lifting device, which is used to move the scanning device up and down. The lifting device is mounted on the translation device. However, with increasingly higher requirements for personalized patterns, current 3D human body scanners have the following shortcomings: Current 3D human body scanning technology does not accurately generate the connection between the feet and lower legs, neglecting the structure of this area and thus lacking comprehensiveness. Furthermore, current 3D human body scanning technology overlooks some details after scanning, such as the scapular prominence, the lower contour of the female breasts, and the spinal curve. These details are crucial for achieving an optimal fit and will affect the generation of personalized patterns.

[0003] To address these issues, we propose a personalized pattern automatic generation system based on 3D scanning. Summary of the Invention

[0029] In use, the customer wears a special compression garment and stands at the foot marker 15 on the rotating platform 12, facing the scanning assembly 2. The customer holds onto the handrail 44 on the handrail assembly 4, adjusting its height as needed. The scanning assembly 2 then activates, with the first depth camera scanner 26, the second depth camera scanner 29, and the third depth camera scanner 213 performing a full scan, adjusting their height to ensure complete scanning. The third depth camera scanner 213 also adjusts its angle to scan the junction of the lower leg and foot. Meanwhile, the two second high-resolution depth camera scanners 37 in the supplementary scanning assembly 3 perform a high-resolution scan of the scapula area. The high-resolution depth camera 33 performs a high-resolution scan of the lumbar spine curve, while two second high-resolution depth camera scanners 37 change position to scan the back spine curve. Simultaneously, the rotating stage 12 rotates the client, and when facing the supplementary scanning component 3, the first high-resolution depth camera 33 quickly performs a high-resolution scan of the lower chest contour. This continues until the client completes a full rotation, completing the scan. The data from the scanning components 2 and 3 are processed into raw scan data within the system. This raw scan data undergoes noise reduction, smoothing, hole filling, and simplification. The high-resolution data from the supplementary scanning component 3 is then combined with the data from the scanning component 2 to obtain a clean and complete mesh model, which is then identified and corrected. The system aligns the user's standing posture (e.g., arms outstretched at a certain angle) with a standard human body template. Using deep learning CNNs, graph neural networks, or traditional computer vision algorithms, it automatically identifies key anatomical landmarks such as the neck-shoulder point, bust point, waist point, knee point, and ankle point. These points are fundamental to size measurement. Based on these identified reference points, the system automatically calculates a series of key body dimensions and generates virtual lines crucial for pattern making, such as neckline, shoulder line, armhole line, and side seam line. The pattern system has a built-in database of basic patterns covering different garment categories such as shirts, suits, skirts, and standard sizes. Each basic pattern is a parametric model based on clothing engineering. By combining traditional pattern-making experience with machine learning, a detailed rule base is established. These rules define which control points on the pattern, how they move, and by how much when a body size, such as the chest circumference, changes. For example, if the chest circumference increases by Zcm, the width of the front and back pieces increases by Xcm, and the armhole depth increases by Ycm, the extracted personalized user dimensions are input into the rule base to drive the basic pattern to automatically adjust and generate a new personalized pattern. In the scanning component 2 of this invention, the third depth camera scanner 213 mainly scans the feet and calves. The third depth camera scanner 213 can change its angle and can scan the connection position between the calves and feet, including the approximate skin folds at that location, resulting in a more comprehensive scan.The supplementary scanning component 3 of this invention employs high-resolution scanning. Two second high-resolution depth camera scanners 37 can change position and angle to facilitate high-resolution supplementary scanning of the scapular region and the back spine curve. Two first high-resolution depth camera scanners 33 can change angle to facilitate high-resolution supplementary scanning of the lower chest contour and the lumbar spine curve. This process supplements the details of the human body model scanned by the scanning component 2, generating a detailed human body model. This ensures that the subsequently generated pattern fits the body perfectly.
