摘　　要：基于LED柱面屏的全景三维显示系统通过旋转的LED与狭缝光栅来重构三维物体的光场。介绍了该系统的原理及架构;设计了一种适应该系统特性的三维数据生成方法;进一步采用增量传输方法来减少系统的传输带宽负荷;最后对数据生成算法进行了误差分析。实验结果表明我们在三维显示系统柱体空间中成功再现了可周视的三维场景。An omnidirectional-view 3D display system based on LED cylindrical screen reconstructed 3D light field by utilizing revolving LEDs and parallax barrier. The principle and configuration were introduced firstly. A display-data generation method for this system was then designed. The incremental transmission algorithm was adopted to reduce the burden of transmission bandwidth. The approximation error in the process of data generation was analyzed finally. The experiment results show that a 360 viewable 3D. scene is reconstructed in the cylindrical display space successfully.
