摘要: 本文提出的灰度/深度图象序列的三维内插方法,摆脱了原实摄路径限制,可在空间内任意巡行。采用空间稀疏化采样,从而达到大量节省存储量和高度灵活地可控再现空间场景的目的。为解决三维内插中庞大的计算量,本文研究了快速而实用的散点算法和深度适应的Warp算法。通过介绍三维内插的几种简单情形,导出了一些简单、实用的算法。计算机仿真结果显示了这一新方法是完全可行的。Abstract: A three-dimensional space interpolation method of grey-depth image sequence is presented. The way breaks away from the limit of original practical photographing route. The pictures can cruise at will in space. By using space sparse sampling, the memorial capacity can be decreased greatly and the reproduced scenes can be controlled. To solve complex computations in three-dimensional interpolation algorithm, a fast and practical algorithm of scattered space lattice and the Warp algorithm with proper depth are studied. By several simple aspects of the three dimensional space interpolation, some simple and practical algorithms are developed. Some results of simulated experiments with computers show that the new method is absolutely feasible.
