Optical measurement and interference techniques

The 3D display using super multi-view images is expected as a display that enables to reproduce natural stereoscopic view. This 3D display needs about 100 views ideally, but actually available view sources from cameras are 10 - 20. So real-time view interpolation is needed. This research aims at a real- time view interpolation system. We have developed a prototype system that inputs four video images and generates several views. The system consists of two parts: acquisition part and data processing unit. The acquisition part has a multi-view camera that has four video cameras on the X-theta mechanical stage. It captures four view images and multiplexes them into digital signal stream. The data processing unit has four DSP chips and performs camera calibration and view interpolation, so that various processing algorithms can be examined. As for the view interpolation, we adopted an adaptive filtering technique on EPI. By this technique, multi-view images are interpolated on the EPIs adaptively by the most suitable filters. And, in order to perform view interpolation with high accuracy, camera calibration is studied. The details of the prototype system, examination of view interpolation and camera calibration are described.
