摘要

基于全息单元的有效视角图像切片嵌合法是一种对两步法进行模拟的全息体视图打印方法,这种方法可以利用少量的采样图像生成具有高质量再现像的全息体视图。但由于此方法要建立精确的全息单元对应关系来获取有效视角图像切片,因此只有在满足一定位置约束条件的情形下才能使用。为解决这一问题,提出了一种针对一般情形的全息单元有效视角图像切片嵌合法,用于全息体视图打印。所提方法利用全息单元的近似对应替代全息单元的精确对应,以获取有效视角图像切片,使其适用于一般情形。经光学实验验证,所提方法同样可以利用少量的采样图像生成具有高质量再现像的全息体视图,与有效视角切片嵌合法进行比较,虽然有效视角图像切片获取的方式不同,但两种方法获得的全息体视图再现像的质量相当,而所提方法的打印效率更高,且可以对“像素对应”全息体视图进行改进。

Abstract

The hogel-based effective perspective image segmentation and mosaicking (EPISM) method utilizes a two-step approach for holographic stereogram printing. This method can generate a holographic stereogram with high-quality reconstructed images using only a few sampled images. However, this method needs to establish an accurate correspondence among hogels to obtain effective perspective image segments, and it can be utilized only when certain position constraints are satisfied. To solve this problem, we propose a general hogel-based EPISM method for holographic stereogram printing in this study. The proposed method uses an approximate correspondence of hogels instead of an accurate correspondence of hogels to obtain several effective perspective image segments, so it can be applied to general cases. Furthermore, using optical experiments, we verify that the proposed method can generate a holographic stereogram with high-quality reconstructed images by employing a few sampled images. Although the way to obtain the effective perspective image segments is different, the reconstructed images of the holographic stereograms obtained by the two methods are with the same good quality. The printing efficiency of the proposed method is higher than that of the EPISM method, and the proposed method can also be utilized to improve the “pixel correspondence” holographic stereogram.
