Abstract
Recently, the graphics processing capabilities of graphics systems have improved a lot, and more and more information must be presented to the users. While the display resolution of monitors is still what it is 20 years ago, and becomes the bottleneck of visualization. This leads to recent interest in the research for high-resolution displays. One great solution is to use multiple projectors tiled together to form a large logical display wall and provide high display resolutions and large physical display sizes. This paper presents a survey of the construction process of these kinds of multi-projector tiled display wall systems. The hardware construction problem is first explored. And then we describe the two most important problems of multi-projector tiled display wall systems, i.e. geometric calibration and photometric calibration of projectors. Various algorithms are addressed and compared. Lastly, an introduction of the high resolution image generation via distributed rendering is presented.
