Method and system for optical alignments for three-dimensional (3D) projection
Orientation, convergence, and brightness balance corrections for a stereoscopic projection system are achieved by employing a novel test pattern in a low-cost alignment method to allow accurate, rapid alignment of the illuminator, film, and stereoscopic lens. The method and test pattern are also applicable for aligning a dual projector system, in which two projectors are used for projecting right- and left-eye images, respectively.
