ABSTRACT:
A system for registering images produced by projectors on a screen or other viewing surface is described herein. Two or more projectors are used with a laser attached to one of the projectors. The laser emits a reference point on the screen and a light-sensitive sensor such as a diode array or TV camera is connected to the other projector to allow a determination of the reference point. One motion system is connected to one of the projectors and the laser and another motion system is connected to the other projector and the sensor. A computer is coupled to both motion systems, the laser and the sensor so that the computer will cause the projectors to move so that the images produced by the projectors are always registered and are believable to an observer.
