| Resumen: | In this paper, an efficient hologram generation method via multi-layer WRPs and optimal segmentation is proposed. The method consists of four steps: First, the 3D object is discretized into point clouds and classified into depth-based groups, with each group assigned an independent WRP. Then, the sub-holograms for each point on its corresponding WRP are calculated using Fresnel diffraction theory. Third, by analyzing the viewing area, the sub-holograms are optimally segmented to obtain optimal diffraction regions (ODRs). Moreover, these ODRs are coherently superimposed to obtain the complex amplitude distribution. Finally, the complex amplitude distribution is propagated onto the holographic plane to obtain the final hologram. Experimental results demonstrate an 82.4% reduction in calculation time compared to traditional NLUT methods, while numerical and optical experiments confirm high-fidelity color reconstruction. By leveraging multi-layer WRPs and optimized segmentation, this method achieves substantial calculational efficiency improvements without compromising display quality, offering a promising solution for real-time holographic display applications. |
