Perspective Camera Model for Layer Optimization of 3D Layered Display

3D layered displays are composed of a backlight and multiple LCD panels. To reproduce a 3D scene with such displays, a light field is given as input to optimize the layers' images that are displayed by each LCD panel. Current works optimize the layers using parallel rays (orthographic camera model) or do not take into account the distance of the user during the layers' optimization. In this paper, we present the use of the perspective model during the layer's optimization and guidelines for camera parameters based on the functioning of these displays. By using a more realistic camera model during the layers' optimization, a higher quality rendering is expected for close and middle viewing distances while giving similar quality for far distances. In the experiments, we observe that cameras' positioning can be adjusted to enhance the quality of high-parallax light fields. As a final result, the proposed method achieves higher quality on closer ranges to the 3D display when compared to the conventional method using parallel rays.
