Graphics processing unit (GPU) based fast calculation method for computer generated spherical hologram (CGSH) of a real-existing object is proposed.Three-dimensional (3D) point cloud constructed by capturing from multiple directions using depth camera.The GPU used in both generation part and numerical reconstruction the CGSH.The improved efficiency verified comparing computation speed between central (CPU) implementation.
