A Free-viewpoint TV System
نویسندگان
چکیده
We propose an implementation of a model-based free-viewpoint TV (FTV) system using only three uncalibrated cameras. FTV is next-generation media that enables us to see a scene from any viewpoint. A modelbased approach for realizing FTV requires real-time 3D object capture using multiple cameras. Here, we propose a system for reconstructing 3D object surfaces using the so-called 2D continuous dynamic programming (2DCDP) method with factorization. 2DCDP is a powerful technique for full-pixel optimal matching. It provides pixel correspondences between the images captured by the three cameras. The proposed system works well as a promising FTV system.

FTV (Free viewpoint TV) and Creation of Ray-Based Image Engineering
Free viewpoint TV (FTV) enables us to view a distant 3D world by freely changing our viewpoints as if we were there. FTV will bring an epochal change in the history of television since this function has not yet been achieved by conventional TV technology. We proposed the concept of FTV and verified its feasibility using the world’s first real-time system including the complete chain of operatio...

The iGLANCE project aims at making interactive free viewpoint selection possible in 3D TV broadcasted media. This means that the viewer can select and interactively change the viewpoint of a stereoscopic streamed video. The interactivity is enabled by broadcasting a number of video streams from several viewpoints, consisting of a traditional 2D video and additionally depth information for each ...

Fig. 1 shows a Free viewpoint TV (FTV) system [7]. FTV can generate very natural free viewpoint images in real time as shown in Fig. 2. A scene is captured using a dense array of synchronized cameras. The camera images are placed in a simple manner forming a Ray Space [8] that allows rendering the scene from any position by simple processing. So the user can view the scene not only from the ori...
