Abstract

Holographic stereogram opens up a new way for holographic 3D display of objects, and has high research value and significance in commercial, military and other aspects. In order to write real and virtual three-dimensional (3D) scenes in holographic stereogram at the same time, so as to achieve the display effect of augmented reality, a light field fusion method is proposed. The basic principle of light field fusion is introduced. The light field sampling is introduced and completed, and depth image based rendering (DIBR) algorithm is applied for regularization and densification of sampled images. The projection relationship of the light rays are analyzed, and the pixel level light field fusion is accomplished. Effective perspectives segmentation and mosaicking (EPISM) holographic stereogram printing method is used to write and reproduce the fused light field which further verifies the effectiveness of the proposed method.
