摘要
全息体视图打印技术是当下广泛应用的一种全息技术。近年来本课题组提出了一种新的对视角图像进行预处理并进行全息体视图打印的方法,称为有效视角图像切片嵌合(EPISM)法,该方法可以通过一步记录实现传统两步法的全息打印效果,具有很高的研究价值。为了在光学实验之前对EPISM法全息体视图的打印结果进行预测,提出一种EPISM法全息体视图的数值重构算法,采用该算法对EPISM法处理过的合成视角图像进行数值重构,可以在光学打印之前预先得到不同观察角度和观察位置所看到的再现图像。将数值重构图像与原始采样图像以及光学实验再现像进行比较,结果表明:该算法可以较好地对EPISM法全息体视图打印的光学实验结果进行模拟。
Abstract
Holographic stereogram printing technology is a widely used holographic technology. In recent years, our project team has proposed a new method to preprocess the perspective images and print the holographic stereograms, called as the effective perspective image segmentation and mosaicking (EPISM) method, in which the holographic printing effect can be achieved via one-step recording beyond the traditional two-step recording, and thus it possesses high research value. In order to predict the printing results of holographic stereograms based on the EPISM method before optical experiments, a numerical algorithm for the reconstruction of holographic stereograms after EPISM is proposed. This algorithm performs a numerical reconstruction of synthetic perspective images processed by the EPISM method and the reproduced images seen at different viewing angles and viewing positions prior to optical printing can be pre-obtained. Through the comparison among the original sampling images, the numerically reconstructed images and the experimentally reproduced images, it is found that the proposed algorithm can be used to simulate the optical experimental results of holographic stereogram printing with the EPISM method.
