<p>An automated geometry correction system and method for rear-projection systems (10) is provided. The automated geometry correction system comprises at least one fiducial (34) placed along each edge (26,28,29,30) of the image screen (22) to permit a correspondence between the image coordinate system of the projection engine (20), and the screen coordinate system of the image screen (22). Based on the established correspondence, an image warping algorithm is used to effect an inverse distortion for matching a source image to the projection engine and the image screen, thereby effecting the geometric correction.</p> |
