In this paper, a novel method to generate computer-generated holograms(CGH) of a real three-dimensional(3D) object using stereoscopic video images is proposed. Stereoscopic video images of a real 3D object are captured with a 3D camera system and disparity maps between the left and right image pairs are estimated on the frame basis. Then, depth data for each pixel of the object can be extracted from these estimated disparity maps. Using these depth data and original color images, hologram patterns of a real object can be computationally generated. In the experiment with a 3D adaptor(3D58 LenSys, Wasol) system, stereoscopic images of a real 3D object of 'cup' are captured and its depth data are extracted from them. Then, CGH patterns are generated with these depth-annotated images of the 'cup' and experimentally displayed via a holographic display system.
