This work focuses on the generation of three-dimensional (3D)-scene information as well as the fusion of real and virtual 3D scene information for the full-parallax holographic stereogram based on the effective perspective images’ segmentation and mosaicking (EPISM) method. The improved depth-image-based rendering (DIBR) method was used to generate the virtual viewpoint images of the real 3D scene, and the regularization and densification processing models of the degraded light field were established; as a result, the real sampling-light field was reconstructed. Combined with the computer-rendered virtual 3D scene information, a “real + virtual” light-field fusion method based on a pixel-affine-projection was proposed to realize the fusion of the real and virtual 3D scene. The fusion information was then processed by the EPISM encoding and was then holographically printed. The optical experiment results showed that the full-parallax holographic stereogram with the real–virtual scene-fused 3D scenes could be correctly printed and reconstructed, which validated the effectiveness of our proposed method.

真实虚拟 3D 场景融合全视差全息立体图的实现

这项工作的重点是基于有效透视图像的分割和镶嵌 (EPISM) 方法的全视差全息立体图的 3D (3D) 场景信息的生成以及真实和虚拟 3D 场景信息的融合。采用改进的基于深度图像的渲染（DIBR）方法生成真实3D场景的虚拟视点图像，建立退化光场的正则化和致密化处理模型；结果，重建了真实的采样光场。结合计算机渲染的虚拟3D场景信息，提出了一种基于像素仿射投影的“真实+虚拟”光场融合方法，实现了真实与虚拟3D场景的融合。然后融合信息通过 EPISM 编码进行处理，然后进行全息打印。光学实验结果表明，具有真实-虚拟场景融合的3D场景的全视差全息立体图可以正确打印和重建，这验证了我们提出的方法的有效性。
