摘　　要：在人体骨骼结构的虚拟现实教学系统开发中 ,使用人体的二维X CT断层扫描图像作为原始数据 ,使用单一阈值结合数学形态学、三维连通域结合边缘检测、相关性搜索等分割算法 ,将骨骼同人体其他组织分割开来 ,并且实现了各块骨骼之间的分割。已经成功地分割出了 33块骨骼 (骨骼群 )。In the development of virtual reality teaching system of human skeletal anatomy, the whole\|body X\|CT slices of a female were used as the original database. Using a single threshold, segmentation algorithms, combining mathematical morphology, three\|dimensional linkage, edge detection, and correlation search, etc. not only bones could be distinguished from other human tissues, but also different bones could be distinguished from each other. 33 bones (bone groups) have been distinguished successfully.
