3维图像数据场的快速重建
摘 要
3维图像重建中最典型的一类算法是体绘制方法,然而由于体绘制中的重采样和插值这两类基本运算,其计算量却是很大的,这往往影响重建的速度,为此,提出了在重建过程中采用减少插值、快速插值以及快速重采样等多项措施和方法,以加速3维图像的重建.实验表明,采用该方法重建时间约缩短了1/3,可见,这些措施和方法是切实可行有效的.

The Realization of Fast Reconstruction of 3D Image Data Fields
() Abstract
Volume rendering method is one of the most typical algorithms of 3D image reconstruction. The two basic operations, resampling and interpolation, are the most time-consuming operations, which usually affect the reconstruction speed. So, some measures and methods of decreasing interpolation, fast interpolation and fast resampling are proposed in paper. The result shows these measures is practical and effective.
