Abstract
A method of calibrating a head up display system includes projecting augmented reality graphics with a picture generation unit, and initiating calibration of the system, including projecting an eye-box pattern to a face of a driver that is not visible to the driver of the vehicle and is detectable by a driver monitoring system (DMS), capturing images containing the face of the driver and the eye-box pattern, receiving and analyzing, by the system controller, the images and calculating a position of eyes of the driver relative to the eye-box by measuring a distance from the eyes to a boundary of the eye-box pattern, and calculating a depth position of the eyes of the driver by measuring width variation within the projected eye-box pattern, and applying adjustments to the image projected by the PGU based on the calculated position of the eyes of the driver relative to the eye-box.
