Abstract
The present disclosure is directed to an approach to solve camera calibration from a single picture of a simply structured light field created by viewing a carefully designed lenticular sheet. The lenticular sheet has different colors visible at different relative orientations and gives linear constraints on the K-1?R matrix which can be decomposed to give the rotation and calibration. The method uses geometric cues from hue measurements and does not require a correspondence between a point in the image and a point on the calibration pattern.
