在三维重建中求取不规则形体体积的一种算法

A Kind of Computation for Calculating the Volume When Three-Dimensional Reconstruct

该文是针对在二维截面图象重建三维立体图形后需计算模型参数时而提出的一种算法。该算法中采用了三次参数样条函数求取二维截面面积；并提出了一种求取非平行截面重构的三维立体图形体积算法。

This paper gives a kind of computation for calculating the model parameters that needed,when three-dimensional objects are reconstructed based on two-dimensional sectional images. Thrice spline functions are used in getting areas of two-dimensional sectional images. It also gives out how to calculate the volume of a three-dimepsional object that reconstructed from nonparallel sections.
