In this paper, the production process of holographic stereograms for digital human portraits, which are increasing interest in the field of holographic art, was shown. The digital human face model was produced using real-object based 3D modeling. After taking a human portrait image with 7 multi-view cameras, it was replaced with a digital human image through post processing. In order to produce digital holographic stereograms, more viewpoint images must be extracted from the face of the digital human. 768 viewpoint images were generated using the neural network multi-view interpolation method from 7 multi-view images. Finally, the process of manufacturing digital holographic stereogram of a digital human was explained, and the results of the experiment were shown.
