摘要
Abstract
This paper presents a newly developed stereo vision system for generating 3D images of garments attired by a subject or on a mannequin. 3D clothing images provide more realistic and effective visualization for showing clothing's style, drape, and fit than 2D images. The system consists of four identical imaging units that can be reconfigured to cover the top, bottom or entire body. Each unit contains a pair of digital cameras and a projector. The cameras capture two images from different perspecfives, and the projector creates artificial textures" onto the clothing surface that help to reduce stereo matching ambiguity. A two-phase algorithm was developed to permit sub-pixel, dense stereo matching. In the first phase, the foreground (garment) is segmented by using a predefined virtual interface in the disparity space image, and a coarse disparity map is generated with block matching. In the second phase, local least squares matching is performed along with global optimization within a regularization framework which ensures both accuracy and reliability of 3D data generation. The unorganized data clouds are the processed by a surface modeling algorithm, which is based on a triangular mesh, surface subdivision and optimization, to reconstruct smooth and complete a clothing surface.关键词
