1. A method for image capture calibration, the method comprising:
identifying a set of real source keypoints from a real source image of a calibration pattern;
computing a set of ideal source keypoints based on the set of real source keypoints;
identifying ideal destination keypoints based on the ideal source keypoints;
adding boundary keypoints to the set of real source keypoints and the set of ideal destination keypoints; and
determining a set of term coefficients based on a mapping of the real source keypoints to the ideal destination keypoints.
