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 invention relates to a three-dimensional clothing modeling method based on a style descriptor, which belongs to the technical field of computer graphics and computer-aided graphic design. The present invention first inputs a three-dimensional clothing model set, and through shape and style analysis, separates three-dimensional clothing parts with consistent styles and structures to realize semantic segmentation; clusters the divided three-dimensional clothing part models into four categories to form a three-dimensional clothing part library ; Then take the area and boundary perimeter ratio of the clothing part model as the main geometric shape feature, define the style descriptor for measuring the recombination of the clothing part; according to the defined style descriptor, and then according to the target model, aggregate The source model after class is optimized globally; finally, new 3D clothing is output through natural splicing. The invention avoids the cumbersome clothing modeling process, improves the three-dimensional clothing modeling efficiency, can effectively meet the current large-scale three-dimensional clothing quantity requirements, and has the advantages of practicability, effectiveness and the like.

Description

technical field [0001] The invention relates to a three-dimensional clothing modeling method based on style descriptors, in particular to a shape analysis and geometric processing method of a three-dimensional clothing model, belonging to the technical field of computer graphics and computer-aided graphic design. Background technique [0002] Designing and quickly creating 3D clothing models directly from scratch is not an easy task, and only limited 3D clothing models can be generated. In the field of traditional 3D clothing design, professional clothing aided design systems (such as Lectra, Gerber, CLO 3D) and other modeling tools are used to generate 3D clothing models from 2D templates. However, these tools are difficult to learn and complex to model, 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 ideal laboratory scenarios, and the ...
