Claim 0:
1. A head up display for a vehicle, comprising:
a display device configured to output light forming an image;
an optical system configured to control a path of the light such that the image is output towards a light transmission region; and
a controller configured to,
generate the image based on a first view and a second view such that a virtual image is produced on a ground surface in the light transmission region, the first view being towards the ground surface, the second view being towards a 3D space above the ground surface, the first view and the second view being based on an eye-box, the ground surface being in front of the vehicle, the virtual image including a graphic object having a stereoscopic effect, and
control the display device to output the image,

wherein the optical system is configured to output the virtual image corresponding to the image on the ground surface,
wherein the controller is configured to generate the graphic object with respect to the ground surface by using the optical system, and
wherein the graphic object is generated by,
making the first view and the second view on the basis of the eye-box consistent with each other, and
projecting a first object onto the ground surface using a first conversion matrix, the first object corresponding to the graphic object, and the first conversion matrix corresponding to the first view and the second view.
