Abstract:

在激光扫描共焦显微三维成像,CT成像,MRI成像,以及在图象处理和识别中,三维物体的显示是必不可少的,目前,最流行的显示方式是虚拟物体的三维重建,通常虚拟物体三维重中以采用体素级重建,可也以采用切片极重建,由于切片级重建仍需要解决物体轮廓对应,分叉曲面,轮廓拼接等关键性问题,为此,提出了一些新的方法,在这些方法中,轮廓的对应采用OR运算和AND运算来确定,如果两个轮廓的OR和ND运算结果满足预先设置的准则,则这两个轮廓相对应;分叉曲面采用数字形态学方法来分解,其由形态学方法生成的边界就是分叉曲面的分割线,轮廓拼拦则是将对应轮廓经多边形简化后,由三角形接拼法来构成表面,且三角形是根据最小轮廓跨接边准则来构建的,通过对这些方法进行的实验结果表明,理论与实际完全相符,这些方法的优点是编程简单,运算速度快。
