The Mannequins Modeling Based On 3D Point Cloud Data

With the development of technologies in the garment industry, 3D-garment CAD is becoming the trend of garment design, which means the importance of the mannequin modeling. The mannequin modeling will influence the performance of the garment design directly, and be closely related to the three-dimensional simulation of the garment. Therefore exploring 3D mannequin modeling method is valuable and of extensive prospect for application.Based on the mannequin data from 3D non-contact body scanning, this paper discussed how to store and process the point cloud data, how to rebuild and display the mannequins. Specific researches include the storage structure of the point cloud data based on the two-dimensional chain table, the reduction algorithm of the point cloud data based on the difference method, hole-filling and noise-filtering in the application of Rapidform software, the extraction of the top mannequin data based on anthropometry standard, the Crust algorithm of the mannequin modeling based on Voronoi and Delaunay triangulation, the mannequin modeling in MATLAB platform.Using a mannequin data file, this paper builds the mannequin and the top mannequin modeling. Experiments result showed that this method can build model quickly and efficiently; the obtained mannequin met the standard exactly. In a word, this method lays a good foundation for the further development of 3D-garment CAD system.
