提出了一种几何模型对人体进行建模,并得出可以智能修改的人台模型.这种几何模型整合了B样条曲线和三角面片的优点.对于人体点云数据进行Delaunay三角化处理,然后用插值B样条曲线对一系列的水平截面与三角化模型的交点.二次的三角化是利用在不同截面中的插值B样条曲线生成的等间距节点.这一系列的处理使得插值B样条曲线和三角面片整合在一起.用这个方法建立的人台可以通过输入关键围度尺寸,生成新人台模型,并且通过展开参数化的人台模型生成服装样板.%A hybrid geometric representation of developing intelligent mannequins was propose. This representation combines a set of piecewise B-spline curves and meshes (PBCM) of modeling a human body obtained from scanner. Firstly, the scanned body in a form of point cloud is triangulated using Delaunay triangulation. Piecewise B-spline curves then interpolate the intersection points about horizontal planes and the triangulated model. By correctly indexing the points on the B-spline curves, a new triangle meshes axe then generated and integrated with the B-spline curves. The intelligent mannequin modeled by the PBCM can be flexibly modified by input measurements of key positions. Garment pattern generation also benefits from the paramterization of the PBCM.
