Claim 10:
11. The method of claim 10, wherein determining the reference camera deviation matrix further comprises:
identifying a plurality of perceived dots of the reference graphic in the first reference image;
determining an actual x-coordinate and an actual y-coordinate of each of the plurality of perceived dots of the reference graphic in the first reference image;
generating an actual reference graphic matrix, wherein each element of the actual reference graphic matrix contains the actual x-coordinate and the actual y-coordinate of one of the plurality of perceived dots of the reference graphic in the first reference image; and
calculating the reference camera deviation matrix by subtracting the actual reference graphic matrix from an intended reference graphic matrix, wherein the intended reference graphic matrix is a two-dimensional array including an intended x-coordinate and an intended y-coordinate of each of a plurality of projected dots.
