Plug and play projectors (PPP) have been used for several years and combining multiple projectors to display a single image is desirous in order to display large, synchronized displays tiled arrays in high resolution. When it comes to screen size, bigger is only better when resolution is maintained and economics are reasonable.
Researchers at UC Irvine have developed an efficient and useful apparatus and method for self-calibrating multi-projector displays via plug and play projectors. Centralized techniques have been used until now when automatically calibrating large displays by tiling in a 2D array. In these techniques a centralized server managed all of the projectos and also the cameras used to calibrate the display. This invention uses an asynchronus distributed calibration methodology via a display unit that of a self-sufficient module that enables a truly scalable and reconfigurable display without any input from the user.
