Channel based projector calibration

Abstract:

The present disclosure is related to methods and systems for calibrating a projector. The method includes displaying a plurality of calibration patterns, where the calibration patterns are displayed separately by different wavelength channel bands, e.g., red channel, blue channel, green channel. The method then includes receiving by a processing element one or more calibration images. The method then includes determining one or more displacements corresponding to a plurality of pixels in the calibration image with respect to a plurality of pixels in the calibration pattern to adjust for distortions on a per wavelength channel basis.
