摘　　要：提出了一种新的基于视场拼接的全视差三维显示方法及图像生成方案.系统核心部分由一个微投影机阵列、一个反射光路和一个散射屏组构成,图像生成方案采用基于OpenGL的算法实现.为了验证所提出的基于视场拼接理论的正确性,利用液晶显示器、菲涅耳镜组、定向散射屏和背投式反射光路搭建了实验样机.该装置可以在更紧凑的系统结构下显示包括横向视差和纵向视差在内的三维图像,并且通过图像生成算法的配合实现了动态三维显示效果.A novel full-parallax 3D display approach and image generating algorithm are demonstrated. The display system employs a panel display monitor, an array of mini-projectors, a rear projecting light beam and a special orthogonal diffuser. Image generation program is Operated based on OpenGL programming. In order to validate the proposed theory based on spliced view-field, a compact prototype-equipment with LCD, Fresnel lens, directional diffuser and rear projecting structure is proposed. The 3D images and dynamic Videos displayed by the system can be observed at different horizontal and vertical viewpoints, with more compact size and better use experience.
