摘 要:
许多人都认为自动分光立体显示技术将使得家庭视觉体验朝着更自然、更逼真的方向发展。为了营造更逼真、更刺激的VR效果，屏幕越大越好。本文旨在详细介绍运用在3D显示的多视点三维投影系统。三维图像方法的原理是视差的深度暗示。采用的方法的视差不是由于使用特殊光学眼镜或者是特殊的光学头盔作为观察光学图像形成区域而引起的。实验装置系统包括暗箱组、PC组和一个多视点三维显示器。采用了透镜、视差栅栏来制作空间多元多视角的自动分光立体显示器。使用投影仪来模拟分光图像对。这种自动分光显示屏幕的优点在于：容易按比例放大；低成本；投影仪和屏幕间不需要精确对准。本文还研究了该屏幕的制作工艺，并给出了实验结果。[著者文摘]

Abstract:
The autostereoscopic display technology is believed by many to be the next logical development toward a more natural and life-like visual home entertainment experience. In order to provide more realistic and exciting VR effect, it is desirable to have as large screen as possible. The objective of this paper is to provide a detailed overview of a multiview projector system for 3D display. Three-dimensional imaging methods are based on parallaxes as their depth cues. In the method, the parallaxes are provided by creating a viewing zone without use of either a special optical eyeglasses or a special optical headset as their viewing zone-forming optics. The experimental system consists of an array of cameras, clusters of PCs, and a multi-projector 3D display. Using lenticular, not Parallax barrier, to manufacture a multi-view spatially multiplexed autostereoscopic display. The stereoscopic image pairs are presented simultaneously with use of projectors. This kind of autostereoscopic display screen has the advantages of ease to scale up, low cost and no precise alignment between the projectors and the screen required. In the end, the manufacture considerations of such a screen are studied and the experimental results are presented.[著者文摘]
