Long Visualization Depth Autostereoscopic Display using Light Field Rendering based Integral Videography

three-dimensional (3D) computer graphics (CG) image without using special viewing glasses or tracking devices. The images are created by employing a light field rendering and pixel distribution algorithm for integral photography (IP) / integral videography (IV) imaging. How to enhance the image depth, especial the long visualization depth, is a challenge work. In this study, the images are rendered from a referential viewing area for each viewpoint and the elemental images are reconstructed by pixel redistribution method. The corresponding result images are projected to a screen that is separated from the lens array by a referential viewing distance as the setting of image rendering. A photographic film is used to record the elemental image through each lens with a photograph-taken method. Our photograph-taken based IV display enables precise 3D images with long visualization depth to be displayed at long viewing distances without any influence from deviated or distorted lenses in a lens array. We created an autostereoscopic display that appears to have three-dimensionality even when viewed from a distance, with an image depth of 5.7 m or more in front of the display. To the best of our knowledge, the presented long-distance IV display is technically unique as it is the first report of generating an autostereoscopic image with such a long viewing distance in the field of computer graphics.
