摘　　要：建立了一个基于全息定向散射屏的光场三维(3D)成像系统,系统能够实现真实场景与虚拟场景的光场三维显示。详细地分析了光场三维显示在垂直全息定向散射屏下的视点图像内容和投影图像的生成方法,开发了相机采集校正算法和投影显示校正算法,完成了光场三维采集与显示系统的硬件结构设计和软件开发。实验进行了真实场景光场和虚拟场景光场的三维成像,实验结果验证了光场三维成像系统的可行性,同时证明系统中投影图像生成方法和校正算法是正确的。A light-field three-dimensional （3D） imaging systems based on holographic directional scattering-screen is developed, which is able to realize light-field 3D display of real scene and virtual scene. The viewpoint image and the generation method of projected image under holographic directional scattering are detailedly analyzed. The camera calibration algorithm and projector display calibration algorithm are developed, and hardware design and software development of light-field 3D acquisition and 3D display are achieved. Light-field 3D imaging of both real scene and virtual scene are completed in the experiment, and the results of which demonstrate the proposed system is feasible. Meanwhile the results also prove the generation method of projected image and the calibration algorithms are correct.
