Claim 5:
6. The system of claim 5, wherein to determine the vehicle TWD deviation matrix, the vehicle controller is further programmed to:
identify a plurality of perceived dots of the reference graphic in the calibration image;
determine an actual x-coordinate and an actual y-coordinate of each of the plurality of perceived dots of the reference graphic in the calibration image;
generate an actual vehicle TWD matrix, wherein each element of the actual vehicle TWD 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 calibration image; and
calculate the vehicle TWD deviation matrix by subtracting the actual vehicle TWD matrix from the reference TWD camera matrix.
