摘要
全息体视图技术是全息显示技术的研究热点,简要介绍了一种有效视角图像切片嵌合(EPISM)的单步全息体视图打印方法,通过单步打印可以获得凸出于全息干板的再现像,实现传统两步法的打印效果。为了实现白光再现,提高EPISM方法的实用性,分析了参考光光强对再现像亮度的影响,以及场景深度对再现像质量的影响。给出了白光再现的条件,并实现了EPISM方法全息体视图的白光再现。
Abstract
Holographic stereogram printing technology is a research hot spot of holographic display technology. This paper briefly introduces a single-step holographic stereogram printing method based on effective perspective image segmentation and mosaicking (EPISM). The single-step printing can obtain reconstructed image protruding from the holographic plate and achieve the printing effect of traditional two-step method. In order to realize white light reconstruction and improve the practicability of the EPISM method, the influence of the reference light intensity on brightness of the reconstructed image and the influence of scene depth on the quality of the reconstructed image are analyzed. The conditions of white light reconstruction are proposed, and the white light reconstruction of holographic stereogram by EPISM method is realized.
