中文摘要：
提出从中国数字化可视人体数据集中获取骨组织曲线、曲面模型的完整技术路线。首先采用多边形逼近分割图像,轮廓跟踪获得目标组织轮廓的数据点作为型值点,采用周期B样条曲线逼近拟合成封闭曲线,利用B样条曲线控制点影响的局部性性质,调整曲线的控制多边形,获得与目标骨组织边界吻合的轮廓曲线,再将完整的骨组织曲线模型通过直纹面法建立NURBS曲面模型。该技术路线对人体骨组织及其它组织器官的建模提供了一种有效实用的方法。
英文摘要：
A whole technology way of reconstructing curve and surface model of skeletal tissue based on the Chinese digital human data was proposed. Polygonal approximation was first applied to image segmentation and the points required from contour tracing as data result. Periodic B-spline was used to approximate the curve as closed curve. Secondly the boundary curve fitted with the objective skeletal tissue can be acquired by adjusting the controlling polygon according to the local influence property of B-spline. The NURBS surface model of total skeletal tissue was established by ruled method. This method can offer an effective and validate reconstruction method for human skeletal ＆ other tissue and organs.
