长期以来，虚拟现实（VR）一直受到使体验成为可能所需的设备的阻碍;特别是立体眼镜和跟踪设备。自动立体显示设备通过将用户从立体眼镜中解放出来而越来越受欢迎，然而很少有资格作为VR显示器。位于芝加哥的伊利诺伊大学（UIC）的电子可视化实验室（EVL）设计并生产了一种大规模、高分辨率的头部跟踪障碍条自动立体显示系统，该系统产生VR沉浸式体验，而无需用户佩戴任何护具。由此产生的系统称为Varrier，是一个被动视差屏障35面板拼接显示器，可产生宽视野，头部跟踪VR体验。本文介绍了视差屏障自动立体相关的背景材料，提供系统配置和结构细节，检查用于产生立体图像的Varrier交织算法，介绍了校准和测试，并讨论了基于相机的跟踪子系统。
Virtual reality (VR) has long been hampered by the gear needed to make the experience possible; specifically, stereo glasses and tracking devices. Autostereoscopic display devices are gaining popularity by freeing the user from stereo glasses, however few qualify as VR displays. The Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago (UIC) has designed and produced a large scale, high resolution head-tracked barrier-strip autostereoscopic display system that produces a VR immersive experience without requiring the user to wear any encumbrances. The resulting system, called Varrier, is a passive parallax barrier 35-panel tiled display that produces a wide field of view, head-tracked VR experience. This paper presents background material related to parallax barrier autostereoscopy, provides system configuration and construction details, examines Varrier interleaving algorithms used to produce the stereo images, introduces calibration and testing, and discusses the camera-based tracking subsystem.
