Problems solved by technology

At present, there are relatively few studies on the geometric modeling of 3D clothing models, and the research done is mainly aimed at physical modeling. In terms of 3D geometric modeling, because the clothing involved is a complex It is difficult to obtain meaningful analysis and processing results when using a 3D clothing model with a complex topology

Abstract

The present invention, belonging to the technical field of computer graphics and computer assistant graphic design. The method according to the present invention comprises: firstly inputting a three-dimensional garment model set, through shape and style analysis, segmenting the three-dimensional garment parts having the same style structure to achieve semantic segmentation; clustering the three-dimensional garment part models upon the segmentation into four major categories, to form a three-dimensional garment part library; defining a style description measuring recombination of garment parts by using the area of the garment part model and the boarder circumference ratio as major geometric shape features; performing global optimization for the source models of the three-dimensional part model clustering according to the defined style descriptor and target model; and finally outputting a new three-dimensional garment by means of natural splicing. The method according to the present invention avoids the complicated process of garment modeling and improves the efficiency of three-dimensional garment modeling, effectively meets the needs of the present large-scale three-dimensional garment quantity, and has the advantages of practicality and effectiveness.

Description

technical field [0001] The invention relates to a three-dimensional clothing modeling method based on a style descriptor, in particular to a shape analysis and geometric processing method of a three-dimensional clothing model, and belongs to the technical fields of computer graphics and computer-aided graphic design. Background technique [0002] It is not easy to design and quickly create 3D clothing models directly from scratch, and only limited 3D clothing models can be generated. In the field of traditional 3D clothing design, 2D templates are used to generate 3D clothing models with the help of modeling tools such as Lectra, Gerber, CLO 3D, etc., but these tools are difficult to learn and complex in modeling, requiring users to have Professional design knowledge. In the field of reverse engineering, people usually use expensive professional 3D scanning equipment to obtain point cloud data in an ideal laboratory scene, and the complexity of the equipment and environment...
