A Scalable Framework for High-Resolution Immersive Displays

We introduce an immersive display framework that is scalable, easily re-configurable, and does not constrain the display surface geometry. The system achieves very-high resolution display through synchronized rendering and display from multiple PCs and light projectors. The projectors can be placed in a loose configuration and calibrated at run time. A full display is composed of these underlying display devices by blending overlapping regions and pre-warping imagery to correct for distortions due to display surface shape and the viewer's position. The effect is a perceptually correct display of a single high-resolution frame buffer. A major contribution of the work is the addition of cameras into the display environment that assist in calibration of projector positions and the automatic recovery of the display surface shape. In addition, a straightforward synchronization framework is introduced that facilitates communication between the multiple rendering elements for calibration, tracking the user's viewing position, and synchronous endering of a uniform, perceptually correct image.
