Abstract
A method projects one or more image onto a curved display surface. First, a predetermined structured light pattern is projected onto the display surface. A stereo pair of images is acquired of the projected images on the display surface. Then, a quadric transfer function between the predetermined images and the stereo pair of images, via the display surface, is determined. Thus, an arbitrary output image can be warped according to the quadric transfer function so that when it is projected onto the display surface it appears correct.
