摘　　要：针对三维图像数据获取和显示结合的问题,本文设计了一种融合数据采集和显示的端到端系统。该系统根据人眼自然观察方式,采用对应的采集和显示方法提供对物体从输入(采集)端到输出(显示)端可视化的逼真体验。本文重点阐述了系统中采集、传输以及显示部分的软、硬件结构的设计实现,其中输入(采集)端使用相机阵列对物体进行采集,图像经过采集校正后传输到由投影阵列组成的输出(显示)端,进行投影校正后再投影到各向异性散射屏上,以多视真三维显示的方式进行显示。本文对不同参数下的实际物体显示效果进行了对比试验,结果表明,通过合理选择参数,该样机可以很好地以真三维的方式显示采集得到的图像。Aiming at the combination of the acquirement and display of the 3D image data, an integrated system to perform the real-time 3D acquisition and multiview true 3D display was proposed. This integration of input（acquisition） end to output（display） end provided vivid experience in 3D visualization of the objects according to human＇s natural way to view the realistic world. This paper focused on both the architecture design and the implementation of the hardware and software of the acquisition, transmission and display components in our system： the camera array performed the real-time 3D acquisition at the input end and sends the acquisition-aligned images to the output end, where the projector array renders the object or scenes at the anisotropic screen in multi-view true 3D way after the projection-alignment. Different parameters were compared showing that our prototype is able to render true 3D image using the acquired 3D data with proper parameters.
