Claim 12:
13. The three-dimensional profiling system of claim 12, wherein the operations further comprise:
determining a first mapping between pixels of an image acquired by the image acquisition device and points of the plane defined by the sheet of light in the world coordinate system, wherein the first mapping corrects for one or more deformations introduced into the image acquired by the image acquisition device;
determining a transformation between points of the plane defined by the sheet of light in the world coordinate system and pixels of a corrected image, wherein the transformation causes:
successive pixels of each row of pixels of the corrected image to correspond to the successive parallel lines in the plane defined by the sheet of light that are equally spaced along the first axis of the world coordinate system, and
successive pixels of each column of pixels of the corrected image to correspond to the successive parallel lines in the plane defined by the sheet of light that are equally spaced along the second axis of the world coordinate system; and

determining, based on the first mapping and the transformation, a first total correction mapping that maps pixels of the corrected image into points of the image acquired by the image acquisition device.
