Abstract

The invention provides a method for automatically classifying the three-dimensional draping form of fabrics, which is characterized in that it comprises the following steps: extracting the draping characteristic contour line of the three-dimensional draping form of the fabric, performing elliptical Fourier description on the draping characteristic contour line of the three-dimensional draping form, The elliptical Fourier transform is used to describe the drape feature contours of the 3D drape shapes of M samples in the scanned fabric drape database, and the 3D fabric drape contours are automatically classified using a hierarchical clustering method that does not require a given number of clusters. The present invention provides a general parameterization and automatic classification method of three-dimensional fabric drape form, which can effectively extract clustering information from three-dimensional fabric drape form, and complete automatic classification, so as to analyze fabric drape form and pattern more comprehensively and accurately. relationship between physical properties.

Description

technical field [0001] The invention relates to an automatic classification method for three-dimensional fabric drape shapes, which is used for parameter processing and automatic classification after obtaining a large number of real fabric drape three-dimensional models through a three-dimensional scanner, so as to serve fabric performance analysis and virtual fabric reconstruction and clothing design, etc. Background technique [0002] At present, the test and analysis of the static drape performance of fabrics mainly focus on image processing using its plane projection. Because this method cannot fully reflect the three-dimensional shape characteristics of the fabric, it has great limitations. For example, some fabrics with similar drape coefficient and number of nodes have completely different physical properties. [0003] With the popularization of 3D scanners, it is possible to scan a large number of real fabric drapes. Currently, after acquiring and building a 3D fa...
