Claim One:
1. A computer-implemented method for correcting image distortion in an image projected on a surface comprising the operations of: measuring a first distance between an image projection system and a surface using a first measurement device; measuring a second distance between the image projection system and the surface using a second measurement device spatially separated from the first measurement device; calculating a first slope of the surface with respect to a projection path of the image projection system, the first slope corresponding to a first angular offset of the surface with respect to the image projection system; calculating a second slope of the surface with respect to the projection path of the image projection system, the second slope corresponding to a second angular offset of the surface with respect to the image projection system; creating a transform using at least the first slope and the second slope; and applying the transform to a first image, thereby creating a second image.
