3D virtual garment automatic generation method and system

Abstract

The invention provides a 3D virtual garment automatic generation method. The method comprises the first step of establishing a 3D standard figure model, wherein the 3D standard figure model is a triangulated grid curved-surface human body model, the second step of controlling a two-dimensional garment piece paper pattern and adjusting garment piece parameters to make garment pieces adapt to the 3D standard figure model, the third step of sewing the garment pieces into a 3D garment, and the fourth step of attaching a chartlet to the 3D garment and adjusting clothing material quality. The invention further provides a 3D virtual garment automatic generation system. According to the 3D virtual garment automatic generation method and system, each flattened two-dimensional garment piece is in a regular triangle shape and can be integrated with a traditional pattern making technology conveniently; moreover, the parameters of the garment pieces are set according to the degree of wrap of the garment pieces on a human body, so the basic loose quantity and the fit degree of the garment can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of 3D model generation, and in particular relates to a method and system for automatically generating 3D clothing virtual. Background technique [0002] Fabric fabrics can be made into garments by cutting and sewing using garment patterns. In order to make fit and comfortable clothing, anthropometry and body shape analysis are essential technical means. 3D to 2D technology can flatten 3D objects to a 2D plane. This technology can largely realize the conversion of 3D clothing to 2D clothing models. It mainly includes two research directions: surface parameterization and physical energy minimization. [0003] One is surface parameterization, which is a one-to-one mapping of a surface from one space to another. Mapping a 3D surface into a 2D plane can be called flattening. The key to parameterizing a 3D surface is to minimize the distortion caused by the flattening process. There are many metrics used to mea...

AI Technical Summary

Problems solved by technology

[0005] From the current point of view, on the one hand, there are still some shortcomings in previous research: (1) the flattened 2D template presents an irregular shape, which cannot be easily integrated with traditional plate-making technology; (2) directly flatten the human body surface into a clothing model , the basic looseness and fit of the clothing cannot be guaranteed; (3) the dividing lines and darts on the sample board do not conform to the traditional clothing structure habits

On the other hand, the application of 3D clothing virtual technology in the clothing industry is far behind that of film, animation, construction and other industries: (1) Technically simulating flexible fabrics and solving the interaction force between non-rigid human body and clothing is by no means an easy task , the 3D clothing virtual technology still needs to be perfected; (2) The online sales of clothing still need considerable development, and the 3D clothing virtual technology cannot fully reflect and replace the advantages of traditional clothing sales; (3) The development of 3D clothing virtual technology is very difficult , high cost, and certain difficulties in promotion
