There are still have many serious problems with the real-existing scenes acquisition and generation of Hologram. In this research, an efficient CGH scheme that using orthographic projection images and depth map for real-existing scenes is proposed. The orthographic projection images and depth map are generated from 3D scanned model which is captured using depth camera. The proposed method generates Multiview images with full scanned real object with not only color information but depth information for hologram generation. The additional depth information can be used in additional artifact. This method reduces the number of angular samplings of the viewpoint images, provides all the human depth cues without producing any visible artifact.
