摘要
为了提高由有效视角图像切片嵌合(EPISM)方法获得的全息体视图再现像的质量,分析传统EPISM方法生成合成视差图像过程中的拼接错误,提出多参考面的EPISM方法。理论分析表明三维物体与算法参考面或者光轴重合部分的合成视差图像不存在误差,距离算法参考面或者光轴越远,合成视差图像的误差越大。减小采样相机的间隔可以在一定程度上减小误差。为了进一步改善EPISM方法,将传统EPISM方法的单个算法参考面拓展成多个,对生成的多组合成视差图像进行重新组合,最终得到更小误差的合成视差图像。仿真和光学实验结果表明,使用多参考面的EPISM方法可以有效提高全息体视图的成像质量。
Abstract
To improve the quality of the reconstructed image of the holographic stereogram obtaines by the effective viewing angle image slice mosaic (EPISM) method, the stitching error is analyzed during synthetic parallax image generation by the traditional EPISM method, and the EPISM method with multiple reference planes is proposed. Theoretical analysis shows that there are no mosaicking errors in the synthetic parallax image of the part that coincides with the algorithm reference plane or optical axis on the three-dimensional object. The farther away the image reconstruction happen from the algorithm reference plane or optical axis, the more significant the synthetic parallax image error became. Reduction of the sampling camera interval can reduce errors to a certain extent. To further improve the EPISM method, the single algorithm reference surface of the traditional EPISM method is expanded into multiple, and the generated multiple combinations are recombined into parallax images to eventually obtain a synthetic parallax image with less significant errors. Simulation and optical experiment results show that the EPISM method with multi-reference planes can effectively improve the imaging quality of holographic stereogram.
