Abstract
A three-dimensional (3D) image rendering method for a heads-up display (HUD) system including a 3D display apparatus and a catadioptric system is provided. The 3D image rendering method includes determining optical images corresponding to both eyes of a user by applying, to each of the positions of the eyes, an optical transformation that is based on an optical characteristic of the catadioptric system, and rendering an image to be displayed on a display panel included in the 3D display apparatus, based on a position relationship between the optical images and the display panel.
Claims13
A three-dimensional (3D) image rendering method for a heads-up display (HUD) system comprising a 3D display apparatus and a catadioptric system, the 3D image rendering method comprising:
- acquiring positions of both eyes of a user;
- determining positions of optical images of the eyes by optically refracting or reflecting the acquired positions of the eyes, based on a focal point and an optical axis of the catadioptric system comprising a concave mirror or a convex lens, the optical images of the eyes comprising virtual viewpoints of the eyes;
- determining a direction of a ray passing through a pixel included in a display panel included in the 3D display apparatus and an optical element of an optical layer included in the 3D display apparatus based on a virtual viewpoint of an eye, the direction of the ray comprising a direction in which a transmission path of the ray is extended toward a rear surface of the display panel;
- and
- rendering an image to be displayed on the display panel to provide the user with a 3D image by determining a value of the pixel based on the determined direction of the ray and the determined positions of the optical images of the virtual viewpoints of the eyes,
- wherein an optical path determined by an acquired position of the eye and a direction of a ray, extended toward a front surface of the display panel and refracted or reflected by the catadioptric system, passing through the pixel and the optical element corresponds to an optical path determined by a determined position of an optical image of the eye and the direction of the ray, extended toward the rear surface of the display panel, passing through the pixel and the optical element,
- wherein the HUD system is implemented in a vehicle, and
- wherein the catadioptric system is configured to receive rays of the rendered image, and adjust respective directions of the received rays such that rays exiting the catadioptric system reach the eyes of the user through a front side of the vehicle.
A heads-up display (HUD) system comprising:
- a three-dimensional (3D) display apparatus configured to display an image;
- a catadioptric system comprising a concave mirror or a convex lens configured to magnify the image that is output by the 3D display apparatus, and transfer the magnified image to a user;
- a processor configured to:
- acquire positions of both eyes of the user;
- determine positions of optical images of the eyes by optically reflecting or refracting the acquired positions of the eyes, based on a focal point of the catadioptric system, the optical images of the eyes comprising virtual viewpoints of the eyes;
- determine a direction of a ray passing through a pixel included in a display panel included in the 3D display apparatus and an optical element of an optical layer included in the 3D display apparatus based on the virtual viewpoints of the eyes, the direction of the ray comprising a direction in which a transmission path of the ray is extended toward a rear surface of the display panel;
- and
- render an image to be displayed on the display panel to provide the user with a 3D image, based on the determined direction of the ray and the determined positions of the optical images of the virtual viewpoints,
- wherein an optical relationship between the acquired positions of the eyes and a projected location of the image corresponds to an optical relationship between the virtual viewpoints of the eyes and image,
- wherein the HUD system is implemented in a vehicle, and
- wherein the catadioptric system is further configured to receive rays of the rendered image, and adjust respective directions of the received rays such that rays exiting the catadioptric system reach the eyes of the user through a front side of the vehicle.
