Automatic calibration of projection system using non-visible light |
摘要 |
<p>A method and apparatus for calibration of a projection system, comprising projecting visible and non-visible images on at least one image plane, detecting said non-visible images projected on the image plane, and calibrating projection of the visible images using the non-visible images. The visible and non-visible images are simultaneously projected and the non-visible images are continually monitored for automatic calibration of composite displays, without taking the projection system off-line. In addition, calibration can be maintained through continuous automatic adjustment using invisible calibration patterns, even if the system is disturbed while it is operating.</p> |
