1. A 3D display calibration system comprising: a display screen; a camera configured to capture calibration images of the screen; one or more 2D image projectors configured to project a plurality of 2D projection images onto the screen, wherein a projection frustum for the 2D projection images has different locations for a horizontal focus and a vertical focus, wherein the horizontal focus is a vertical line at the 2D image projector and the vertical focus is a horizontal line at a viewer position; and a computer configured to generate the 2D projection images and to process the calibration images captured by the camera; wherein the 2D projection images are calibration patterns; wherein the camera captures the calibration images of the screen while the calibration patterns illuminate the screen; wherein the computer calculates corrections to the 2D projection images in dependence upon the calibration images.
