采用CT切片的三角片曲面重构算法

采用二维平行轮廓线三维重建表面是三维建模研究领域的一项重要研究课题，具有非常广泛的应用领域。重建过程中计算量非常庞大，有效地化简重建的数据可以大大提高重建效率。文中提出了一种基于分析轮廓骨架点的表曲面重构算法。首先对CT切片进行预处理及图像分割，然后对轮廓线提取骨架，再进行骨架剪裁，最后采用模拟退火法进行三维重建。该算法使三维重构的数据大大化简，同时克服了局部优化算法中需交互指定初始连接边的缺点。

Triangular Surface Reconstruction in CT Slices

Surface reconstruction from contours is an important subject in 3D modeling, which used in a bread application field. Processing a huge amount of data is needed during reconstruction, so reconstruction efficiency can be improved obviously by simplifying the reconstruction data availably. An approach is proposed for surface reconstruction from contours based on the analysis of skeleton points. The program starts with the CT slices, performs a sequential procedure of 3D image formation, preprocessing, segmentation, thinning and skeleton pruning. It ends with 3D reconstruction. The data of 3D reconstruction are simplified greatly by using the approach. And it overcomes the shortcomings that need to make initial linking sides in the part optimized algorithm.
