Abstract
A three-dimensional augmented reality head-up display includes a display device functioning as a light source; and a freeform surface mirror for reflecting light from the light source onto a windshield of a vehicle. An image created by the light from the light source is focused on the ground in front of the vehicle as a virtual image of a three-dimensional perspective, through a reflection method in which the light from the light source is reflected onto the windshield by means of the freeform surface mirror.
