A spherical hologram-based three-dimensional rotational-motion compensation (SH-3DRMC) method is proposed for the accelerated generation of holographic videos of a three-dimensional (3-D) object moving in space along the arbitrary trajectory with many locally-different curvatures. All those 3-D rotational motions of the object made on each arc can be compensated just by rotating their local spherical holograms along the spherical surfaces matched with the object's moving trajectory using the estimated rotation-axes and angles, which enables a massive reduction of computational complexity of the conventional hologram-generation algorithm and results in an accelerated calculation of holographic videos. Experiments with a test video show that the average calculation times of the conventional NLUT, WRP and 1-D NLUT methods employing the proposed SH-3DRMC scheme have been noticeably reduced by 34.75%, 41.37% and 31.64%, respectively, in comparison with those of their original methods. These good experimental results confirm the feasibility of the proposed system. (C) 2019 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
