基于NURBS插值的散乱数据点人体自由曲面重构技术

The Reconstruction Technique of NURBS-Based 3D-Mannequin with Dense Data Points

本文基于ＮＵＲＢＳ理论体系提出了三维人体自由曲面重构技术：将密集的散乱人体表面数据点进行初步压缩；根据更新的曲线差值算法得到截面上的插值曲线；在曲线上插入控制点形成控制点矩阵；最后根据控制点矩阵构造ＮＵＲＢＳ人体．

The method of 3D-mannequin reconstruction brought forward in this article was based on NURBS theory. It was realized through four steps: reducing original dense data points of body surface, interpolating rows of data points with advanced interpola-tion spline method to get interpolation curves, inserting control points into interpolation curves m order to construct a control point matrix and reconstructing NURBS-based 3D-mannequin.
