Abstract

We propose a novel technique to synchronize elemental images and audio signal and the transmission technique for a glass-free 3D TV system based on integral imaging in real time. The main idea behind the method is to generate real time 3D video based on elemental images synchronized with audio stream. The system uses the depth information and RGB data of per frame of a video through Intel RealSense 3D camera and the audio stream from microphone. The audio file is sampled according to per frame of the video and kept in different buffers but having same index. The frames are divided into elemental images using Elemental Image Generation algorithm and the audio data is synchronized according to the index. Then the stream of elemental images and corresponding audio data is transmitted to data server. The display device fetches and decodes this data to produce video which is viewed as 3D using multi-array of lenses.
