Real-time three-dimensional video reconstruction of real scenes with deep depth using electro-holographic display system

Herein, we demonstrate a real-time, three-dimensional (3D) video-reconstruction system using electro-holography in real-world scenes with deep depth. We calculated computer-generated holograms using 3D information obtained through an RGB-D camera. We successfully reconstructed a 3D video (in real time) of a person moving in real-world space and confirmed that the proposed system operates at ~14 frames per second. In addition, we successfully reconstructed a full-color 3D video of the person. Furthermore, we varied the number of persons moving in the real-world space and evaluated the proposed system's performance by varying the distance between the RGB-D camera and the person(s).
