摘　　要：论述了从点云数据中用三角片重建人体曲面的方法.首先对人体的各部位采用基于曲率变化的方法采样,提取和保存了人体的特征点、特征轮廓线,克服了三角片无语义的缺点,并且生成人体骨架,为后期的动态展示服装打下了基础.然后采用轮廓同步前进法绘制三角片,重建3D人体模型.该建模方法数据量小,能快速生成逼真的人体模型,满足3D虚拟试衣的要求.Reconstructing 3D virtual human body from scattered data point by triangular mesh was introduced.Each part of the body was sampled according to the change of surface curvature of the body.Since human model represented by triangle meshes hardly contains semantic parameters,the characteristic points and contours of the human body was taken out.The skeleton was created based on the human body.Therefore,a good foundation was settled for dynamic garment show.The order of triangle mesh was organized by the method of contour synchronous forwarding, so the smooth surface of the human body was represented. The method with a little data is used easy, and the represented 3D- virtual human body can be used in 3D virtual trying on systems.
