Abstract

Multi cameras are used to acquire depth and color information from real scenes, and then virtually reconstruct uniform point cloud by using a non-uniform sampled method. Multiple relocated point cloud gridding (MR-PCG) method is proposed to accelerate the calculation speed in GPU for full-color holographic system. Computer-generated holograms (CGHs) are obtained by applying a Fast Fourier transform (FFT) diffraction calculation to the grids. Full-color reconstructed images were obtained flexibly and efficiently. The feasibility of our method was confirmed both numerically and optically.
