Improvement on the different scene depth of effective perspective images' segmentation and mosaicking based holographic hologram

摘要

The problem of the reconstructed of different scene depth was analyzed in single-step holographic stereogram printing based on effective perspective images' segmentation and mosaicking (EPISM). The reconstructed quality of short scene depth is bad. the causes of flipping effect in holographic stereogram are studied in detail, and the influence of flipping effect on image quality is alleviated by reducing the size of holographic element (Hogel). The curvature distortion of holographic stereogram is analyzed. The effect of curvature distortion on the reconstructed quality of holographic stereogram is verified by changing the distance of object protruding sampling plane. The theoretical analysis was verified experimentally with different scene depth. The reconstructed image of high quality and short scene depth was obtained, and the practicability of EPISM was improved.
