摘要

大型显示系统通常由许多投影机组成,这些投影机的投影合并在一起形成一个大屏幕。在本文中,我们讨论了将多个投影连接成一个大型显示系统的技术,用于多媒体娱乐和虚拟现实应用。与使用昂贵的基于硬件的无缝合并模块相比,我们采用了基于软件的无缝合并解决方案,该方案用于校准叠加区域的颜色亮度和几何形状。为了扩大其应用范围,我们对几种筛网(平面筛网和弧形筛网)进行了技术改造。我们使用带有加速显卡的PC集群来降低渲染成本。我们的软件合并系统可以在各种大型显示平台上运行。实验表明,系统取得了满意的效果。可以无缝播放avi、wmv、rm等不同编码格式的视频,可以实时无缝渲染3D场景。

Multi-Projector Seamless Display System Based on PC-Cluster
A large display system usually consists of many projectors, whose projections are merged together to form a large screen. In this paper, we discuss technologies to join multiple projections into a large display system for multimedia entertainment and virtual reality applications. In contrast to using expensive hardware-based seamlessly merging modules, we adopt a software-based seamlessly merging solution, which is used to calibrate the color brightness and the geometry in superposed regions. And in order to enlarging its application, we adapt technology to several kinds of screens (plane screen and camber screen). We use PC cluster with accelerated graphics cards to lower rendering costs. Our software merge system can run on a variety of large display platforms. The experiment shows our system obtain the satisfying results. It can seamlessly play videos with different encoding formats, such as avi, wmv, rm etc, and can seamlessly render 3D scenes in real time.
