Abstract
The present invention relates to projection systems. According to one embodiment the system comprises one or more projectors oriented to project an image on a projection screen and one or more image sensors oriented to acquire an image projected on the projection screen. The projector is operated to project a calibration image comprising one or more image fiducials on the image projection screen. The image sensor acquires the projected calibration image including the image fiducials. The respective positions of the image fiducials are identified and the identified fiducial positions are validated by applying a parametric model to compare respective ones of the identified fiducial positions with corresponding approximations of the identified fiducial positions. Corrected fiducial positions are generated when a result of one of the comparisons exceeds an error threshold. Additional embodiments are disclosed and claimed.
