Abstract
Multi-projector displays are commonly used for a wide range of applications such as virtual reality systems, simulators or data visualization where a high resolution image over a large projection surface is required. Such systems are cheap for the resolutions they can provide, can be configured to project images on almost any kind of screen shapes and are easily scalable, but in order to provide a seamless image with no photometric discontinuities they require a precise geometric and colour correction. In this paper, we propose a series of optimization techniques for large projection displays which make the adjustment procedure simpler and faster. Calibrationmethod uses commercial off-the-shelf equipment such as a webcam and an intermediate performance graphics card. Multiple views are used if one camera image can?t cover the entire display with enough resolution. The effect of these optimizations in the calibration of a simulated display formed by 48 projectors are shown.
