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.
