Abstract
A method of calibrating a head-up display system includes training a neural network to predict warp maps for an occupant perspective of a single graphical image projected onto a windshield of the vehicle, projecting, with a digital light projector, a graphical image onto the windshield, capturing, with a camera in proximity to the digital light projector, the graphical image projected onto the windshield, locating, with an occupant monitoring system, an occupant eye ellipse position, predicting, with the neural network, a warp map for an occupant perspective of the projected graphical image based on the location of the digital light projector, the occupant eye ellipse position and a shape of the windshield, applying, with the controller, the warp map to the graphical image projected by the digital light projector, and projecting, with the digital light projector, a corrected graphical image based on the predicted warp map.
