Generating 5D Light Fields in Scattering Media for Representing 3D Images

In this paper, we propose a novel method for displaying 3D images based on a 5D light field representation. In our method, the light fields emitted by a light field projector are projected into 3D scattering media such as fog. The intensity of light lays projected into the scattering media decreases because of the scattering effect of the media. As a result, 5D light fields are generated in the scattering media. The proposed method models the relationship between the 5D light fields and observed images, and uses the relationship for projecting light fields so that the observed image changes according to the viewpoint of observers. In order to achieve accurate and efficient 3D image representation, we describe the relationship not by using a parametric model, but by using an observation based model obtained from a point spread function (PSF) of scattering media. The experimental results show the efficiency of the proposed method.
