1. A method for adjusting a location of an image projected onto a windshield of a vehicle by a head-up display (HUD), the method comprising:
placing a physical target on the windshield at a target location of the projected image;
mounting a fixture to a component within a cabin of the vehicle to position an array of cameras attached to the fixture within a possible line of sight between eyes of a passenger of the vehicle and the target location of the projected image;
capturing a first plurality of images of the physical target using the array of cameras;
determining at least one difference between an actual location of the physical target in each of the first plurality of images and a target location of the physical target in each of the first plurality of images;
controlling the HUD to display a virtual target on the windshield at the target location of the projected image;
capturing a second plurality of images of the virtual target using the array of cameras;
determining a target location of the virtual target in each of the second plurality of images based on the at least one difference;
determining at least one offset between an actual location of the virtual target in each of the second plurality of images and the target location of the virtual target in each of the second plurality of images; and
adjusting the location of the image projected onto the windshield by the HUD based on the at least one offset.
