Claim 9:
10. A method for calibrating a display for a vehicle, the method comprising:
projecting a reference graphic on a reference windscreen using a reference transparent windscreen display (TWD) projector;
capturing a first reference image of the reference graphic using a reference camera;
determining a reference camera deviation matrix, wherein the reference camera deviation matrix encodes deviations in the reference graphic due to characteristics of the reference windscreen;
determining a reference TWD camera transformation matrix based at least in part on the reference camera deviation matrix;
projecting the reference graphic on a vehicle windscreen using a vehicle TWD projector;
capturing a calibration image of the reference graphic using a vehicle TWD camera; and
calculating a vehicle TWD calibration matrix based at least in part on the reference camera deviation matrix, the reference TWD camera transformation matrix, and the calibration image.
