Research on Applied-Information Technology with Data Distribution for Light Field Camera Array

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.

Data Distribution Service

The Open Management Group Data Distribution Service ( OMG DDS ) is a standard for publish-subscribe data distribution systems which is emerging as a specification for data exchange. It is a type of Message Oriented Middleware ( MOM ) that provides various functionalities such as portability and interoperability across many DDS implementations. In this, we create models which are platform independent. One platform can be mapped to others. These platforms can be in different programming languages. The existing issues with this technology include its inability to support request-reply services, file transfer and transaction processing. These issues can be considered as research work for future. Nowadays, there is always a need to exchange data among several communication machines instead of just a single machine. DDS caters this need by allowing data to be sent and received in a distributed environment. While doing so, the various security issues related to data integrity and loss of data are also taken into consideration. In this paper, Data Distribution Service ( DDS ) has been implemented to be used in network centric warfare, in three programming languages i.e Java, C and C++ in order to allow for cross language communication without any loss of data on a standalone mode .Data can also be exchanged between several machines in a distributed environment.

Abstract The full-chain system performance characterization is very important for the optimization design of an integral imaging three-dimensional (3D) display system. In this paper, the acquisition and display processes of 3D scene will be treated as a complete light field information transmission process. The full-chain performance characterization model of an integral imaging 3D display system is established, which uses the 3D voxel, the image depth, and the field of view of the reconstructed images as the 3D display quality evaluation indicators. Unlike most of the previous research results using the ideal integral imaging model, the proposed full-chain performance characterization model considering the diffraction effect and optical aberration of the microlens array, the sampling effect of the detector, 3D image data scaling, and the human visual system, can accurately describe the actual 3D light field transmission and convergence characteristics. The relationships between key parameters of an integral imaging 3D display system and the 3D display quality evaluation indicators are analyzed and discussed by the simulation experiment. The results will be helpful for the optimization design of a high-quality integral imaging 3D display system.
