摘要
简要介绍了有效视差图像分割与重组(EPISM)的单步全息体视图打印方法的基本原理,分析了EPISM方法对不同场景深度再现质量变化的影响。研究了基于EPISM方法的全息体视图视觉跳变问题产生的原因,分析了全息体视图的曲率失真问题,验证了曲率失真对全息体视图再现质量的影响。通过减小全息单元尺寸进行了实验验证,有效提高了较短深度三维场景的再现质量。
Abstract
The basic principle of one-step holographic stereogram printing method based on effective perspective images' segmentation and mosaicking (EPISM) is briefly introduced. The influence of EPISM method on the reconstructed quality change of different scene depths is analyzed. The causes of visual hopping in holographic stereogram based on EPISM are studied. The curvature distortion of holographic stereogram is also analyzed. The effect of curvature distortion on the reconstructed quality of holographic stereogram is verified. The reconstructed quality of the three dimensional scene with short depth is effectively improved when we reduce the size of holographic hogel.
