We propose a method based on the selective pixel sampling algorithm to generate a nonunified integral imaging (II) elemental image array (EIA) with reduced moiré patterns at a low rendering cost and high three-dimensional (3D) resolution. In the proposed method, the redundant 3D information is captured for the nonunified pixel arrangement of elemental images, and the moiré patterns are constrained by the constraint equations. The nonunified EIA's corresponding information is mapped from the obtained 3D information based on the selective pixel sampling algorithm. Appropriate experiments are carried out, and the experimental results show that the proposed method can increase the 3D display quality of the reconstructed 3D images in the II display and reduce rendering costs markedly in the generation of ultra-high-definition EIA.
我们提出了一种基于选择性像素采样算法的方法，以低成本渲染和高三维（3D）分辨率生成具有减少莫尔条纹的非统一积分成像（II）元素图像阵列（EIA）。在所提出的方法中，针对元素图像的非统一像素排列捕获冗余的3D信息，并通过约束方程来约束莫尔条纹。基于选择性像素采样算法，从获得的3D信息中映射非统一EIA的相应信息。进行了适当的实验，实验结果表明，该方法可以提高II显示中重建3D图像的3D显示质量，并在生成超高清EIA时显著降低渲染成本。
