Abstract
A system projects multiple output images on a display surface. The system includes multiple projectors. Each projector includes a processing unit. The processing unit includes a microprocessor, a memory and an I/O interface connected by busses. A projector sub-system coupled to the processing unit is for displaying output images on the display surface. A camera sub-system coupled to the processing unit is for acquiring input images reflecting a geometry of the display surface. The camera sub-system is in a fixed physical relationship to the projector sub-system. A network sub-system coupled to the processing unit is for communicating messages between the projectors. Internal sensors coupled to the processing unit are for determining an orientation of the projector sub-system and the camera sub-system with respect to the display surface.
