Physical yarn woven-pattern digital modeling device and method

Abstract

The invention relates to a physical yarn woven-pattern digital modeling device and a physical yarn woven-pattern digital modeling method. The device comprises a box body, a yarn clamping device, a coiling driving control device, a light source and an imaging system. By using the digital modeling method, various woven structure charts are represented by using basic matrixes, a woven structure database is pre-established, and in the process of modeling, through carrying out row and line expansion on a selected basic matrix, the size of a required woven matrix is obtained; an elliptic cylindrical yarn model is constructed, and the yarn color information is managed in index table form; based on the corresponding relation between the physical sizes of yarns and the image sizes thereof, through taking the selected woven matrix, the warp and weft arrangement sequence of yarns and the weaving spacing as constraints, a physical yarn model image is divided into modeling interwoven points, and the corresponding relation between the modeling interwoven points and the elements of the woven matrix is determined; and according to the information, a yarn woven-pattern three-dimensional model diagram is constructed. According to the invention, the reconstruction of a physical yarn woven-pattern images can be realized quickly.

Description

technical field [0001] The invention relates to the technical field of digital intelligent textiles, in particular to a digital modeling device and method for a physical yarn weaving pattern. Background technique [0002] Yarn weaving style is directly related to the appearance and performance of fabrics and clothing, and plays a pivotal role in textile production. Yarn characteristics such as fineness, color, hairiness and evenness, as well as different arrangements and combinations in the weaving process directly affect the appearance of the fabric. The method of modeling the real yarn can truly reflect the weaving effect of the yarn. According to the specified fabric interweaving structure, yarn arrangement sequence, warp and weft yarn spacing and other information, the image information obtained by the actual yarn can be directly used for modeling, which can truly simulate the appearance and weaving style of the fabric, and provide comprehensive evaluation of yarn quali...

Problems solved by technology

The defects of the above methods are to use the general image or standard image of the yarn for processing and modeling, and it is impossible to extract the appearance characteristics of the specified physical yarn, such as the actual yarn color, thickness deformation and fluff at different positions. , and specify the weaving structure and the arrangement order of the yarns, and quickly establish the weaving style model
