摘要： 在计算机辅助颅像重合研究中,需要在三维颅骨表面的特征位置处做标志,并且在三维空间中需要对标志点进行交互操作,其中在颅骨表面移动标志点是比较复杂的操作,针对这一问题,本文提出了一种基于平面相交的移动标志点方法,经实验表明,该方法能够高效地移动三维标志点,达到理想的效果。

Abstract: In the computer aided photographic superimposition system, it's essential to make mark on the surface of 3D-skull,where is a feature point place. Add also need to operate the marks in the 3D-space .The operation of moving mark is a more difficult one in these operation. In this paper, a new method based on plane intersection is proposed for this question. The experimental result demonstrates the benefits of the method in precision and computational complication.
