Digital design method for three-dimensional prototype garments

Abstract

The invention provides a digital design method for three-dimensional prototype garments. The method comprises the following steps of: establishing a PHBC model according with human body features; obtaining human body feature information on the basis of the PHBC model; adding a loose measure for ensuring garment fitness at a self-defined position of the human body feature information; calculating zooming parameters of required horizontal sections according to the given loose measure, zooming all the sections according to the zooming parameters so as to obtain an edge frame with loose measure distribution; and establishing an expandable curved surface model through the edge frame, and constructing an expandable three-dimensional prototype garment according to the expandable curved surface model. Through the method, an expandable three-dimensional model base sample is realized, and a two-dimensional sample plate is directly obtained via the garment, so that the efficiency of pattern making and pattern modification is improved; deeper feature data of human body is obtained and three-dimensional human body data is deeply analyzed by utilizing a curved surface clustering method and curved surface geometric characteristic analysis method; and a garment structure according with human body is designed.

Description

technical field [0001] The invention relates to the technical field of clothing design, in particular to a digital design method for three-dimensional prototype clothing. Background technique [0002] The degree of clothing fit is an important factor for consumers to purchase clothing products, and the degree of fit depends to a large extent on the plate-making techniques and methods of clothing samples. Existing clothing samples are generally hand-drawn by designers. Due to the differences in the experience of designers in making boards, this process often requires a lot of time or repeated procedures to meet the requirements of the correct fit of the clothing. [0003] The development of computer-aided design (Computer-Aided Design, CAD) has enhanced the accuracy and easy storage of clothing samples, and improved the convenience of modification. However, compared with traditional hand-drawn boards, CAD technology has not greatly improved the model-making process, and the ...

Problems solved by technology

[0007] In the process of research, the inventor found that the templates generated by using computer 3D human body data cannot be practically applied in the industry, nor can it be connected with the traditional way of making clothes with panels. The reasons are as follows: 1. Only from the perspective of computers and geometry 3D clothing is constructed from different angles, without considering the relationship between clothing and human body characteristics, and without effective analysis and integration; 2. Most of the models generated by using 3D clothing are in irregular shapes, which are very different from traditional clothing models , cannot be combined with the traditional actual garment production; 3. The model does not meet the requirements of the basic structure of the garment; 4. There is no systematic fit verification;

[0008] The use of physical methods to design and construct three-dimensional surfaces often cannot provide high accuracy, and the parameters and initialization status of the model will also affect the quality of the final two-dimensional template generation; The error is reduced, but usually the generated templates are irregular shapes or only convex polygons, which cannot be applied to clothing samples

Therefore, using physical or geometric methods to construct developable 3D surfaces has its own limitations
