Depth camera for 3DTV applications

In this paper, we present the depth value accuracy requirements for novel view synthesis in 3DTV and our approach for depth camera based on hybrid method of structured light and active stereo matching. We first review the background on the use of multiview video plus depth(MVD) representation for future 3DTV system, depth acquisition methods and tools for real-time and non-real-time dense depth map acquisition in terms of performance and limitations. Then we use a simple analysis model for novel view synthesis based on DIBR to draw depth value accuracy requirements. Finally we present our approach on depth camera development along with future directions and huddles in developing real-time depth camera usable for 3DTV content production.
