摘      要：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 is constructed by capturing a real-existing object from multiple directions using a depth camera. The GPU based calculation is used in both hologram generation part and numerical reconstruction part of the CGSH. The improved calculation efficiency is verified by comparing the computation speed between central processing unit （CPU） based and GPU based imDlementation.
