摘要
利用八元树进行物体的三维重建是一种十分有效的方法。本文针对医国学图象处理中的实体三维重建,在分析了序列断层图象的空间布局和八元树结构的基础上,提出了一种通过断层序列图象直接建立八元树的快速算法,并易于在微机上编程实现该算法。
It is an efficient way to use octree for 3D reconstruction. In this paper, aiming at the true solid reconsturction of medical images, we propose a fast algorithm for construction octree by slicing images on the basis of analyzing the space layout of medical cross section images and the configuration of octree. Besides this, it is easy to program and carry out.
