Claim 13:
14. A control method of a head up display for a vehicle, comprising:
generating an image based on a first view and a second view such that a virtual image is produced on a ground surface in a 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 a vehicle, the virtual image including a graphic object having a stereoscopic effect; and
controlling a display device to output the image to an optical system configured to convey the image to the light transmission region,
wherein the virtual image is produced by an optical system configured to control a path of light such that the image formed by the light is output towards the light transmission region,
wherein the graphic object is generated 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 to obtain a projected image, and the first conversion matrix corresponding to the first view and the second view.
