Data Distribution Service

The collection of light field is a key part of 3D image rendering and multi-view display system construction. Data exchange of light field frequently used in light field camera array requires high real-time performance and high bandwidth. This paper presents a new method of light field data exchange by applying data distribution service (DDS). Experiment results show it is feasible to apply data distribution service to the light field camera array.

Processing Framework

Anaglyph 3D is a low-cost and popular 3D display method, made out of a photo pair. With only one common camera, however, there are difficulties in capturing moving objects. We suggest using the light field camera, which can be exploited as a computational stereo rig, to capture image pairs simultaneously. A processing framework for making anaglyph 3D image is then proposed. The effectiveness of our proposal is verified visually by experiments.

The Impact

The article describes the role of polarisation in calculation of multiple reflections. A mathematical model of multiple reflections based on the Stokes vector for beam description and Mueller matrices for description of surface properties is presented. On the basis of this model, the global illumination equation is generalised for the polarisation case and is resolved into volume integration. This allows us to obtain an expression for the Monte Carlo method local estimates and to use them for evaluation of light distribution in the scene with consideration of polarisation. The obtained mathematical model was implemented in the software environment using the example of a scene with its surfaces having both diffuse and regular components of reflection. The results presented in the article show that the calculation difference may reach 30 % when polarisation is taken into consideration as compared to standard modelling.
