ALL-AROUND RAY-REPRODUCING 3DTV
Tomohiro Yendo, Toshiaki Fujii, Mehrdad Panahpour Tehrani, Masayuki TanimotoAbstract
In this paper, we propose a live 3D video system that captures rays from 360 degree and reconstructs it as 3D image which can be seen from 360 degree in realtime. The system consists of a ray capturing system, a display system, and a data converter. The ray capturing system is the same as we have already proposed; it consists of a scanning optics system and a high-speed camera. The scanning optics system is composed of a double-parabolic mirror shell and a rotating flat mirror tilted at 45 degrees to the horizontal plane. The mirror shell produces a real image of an object that is placed at the bottom of the shell and the rotating mirror reflect the image to the camera, that enables capturing images from different angles as if the camera is moving. According to the property of the scanning optics system, captured image includes distortion and is rotated. The data converter processes compensation of the distortion and the rotation in real-time. Due to extremely high frame rate, data rate is about 16Gbps. To achive real-time image processing, we developed a special hardware using FPGA. The data converter also converts image data into suitable format for transmitting to the display. The display system is also known as the Seelinder, now we have developed new version of the display. It can receives image data of over 300 views and display it in real-time with 24 bit color depth.
