Abstract
Recent developments in computer graphics hardware and distributed parallel rendering research have greatly improved the rendering capabilities of graphics workstations and PC clusters. However, the display resolution of monitors is still far from being enough, and thus become the bottleneck of visualization. Recently, more and more people are focusing on using multiple projectors to form a large display wall and provide high display resolutions. One essential problem of these kinds of systems is how to calibrate the projectors and make the whole display wall seamless and perfect. In this paper, we introduce our multi-projector tiled display wall calibration system using a digital camera. Compared to the traditional algorithms, our systems have three main contributions, i.e. faster calibration speed, no over illuminations in overlapping regions, and application independent calibration process.
