Abstract

In this work, a method for generating full-parallax synthetic holographic stereograms using enhanced hexagonal hogels and neural graphics primitives is proposed and implemented. The diffraction effect and defocus aberration are introduced to analyze and compare the reconstruction performance between the proposed hexagonal pupil and the traditional square pupil, indicating that the hexagonal pupil offers better performance for floating-out holographic stereograms. Then, the extraction method for effective perspective image segments, along with the formation strategy for the synthetic effective perspective image (SEPI), is analyzed in detail. Torch-ngp is adopted to generate the SEPI from a limited number of perspective images of the 3D scene, where the direct extraction and rendering mechanism significantly improves the generation efficiency of the SEPI. Experimental results demonstrate that the proposed method can efficiently fabricate full-parallax synthetic holographic stereograms with enhanced reconstruction quality.

基于神经图形基元的六边形全息立体图

在这项工作中，提出并实现了一种利用增强六边形栅格和神经图形基元生成全视差合成全息立体图的方法。引入衍射效应和离焦像差，分析比较了六角形瞳孔与传统方形瞳孔的重建性能，表明六角形瞳孔具有更好的漂浮全息立体图重建性能。然后，详细分析了有效透视图像片段的提取方法以及合成有效透视图像（SEPI）的形成策略。采用Torch-ngp从有限数量的3D场景透视图像中生成SEPI，其中直接提取和渲染机制显著提高了SEPI的生成效率。实验结果表明，该方法可以有效地制备全视差合成全息立体图，并提高了重建质量。
