Paper Abstract

Light field display requires a large number of views to achieve an ideal three-dimensional display. Techniques have been proposed for generating virtual views between cameras, using depth information and feature matching between multiple images. However, these methods cannot generate views in front of the cameras and behind the cameras to implement free-view walkthrough for the light filed display. Here a simple and robust method is presented to synthetize virtual views. The key to this technique lies in interpreting the input images as a 4D optical function - the light filed, and new views are generated in real time by ray tracing in appropriate directions. The 4D optical function completely describes the state of the flow of light in an unobstructed space. Once a light field is created, new views of arbitrary camera positions can be constructed by combining and resampling the pre-acquired images. The pixel information constructing a new view can be obtained through the interpolation algorithm, and the weighting factor varies with the position of corresponding pixels based on ray tracing.
