FTV（自由视点电视）是一种创新的视觉媒体，它允许用户通过自由改变视点来观看三维（3D）场景。因此，它可以实现逼真的观看和自由导航的3D场景。FTV是无限观看量的终极3DTV，位居视觉媒体之首。FTV不是传统的基于像素的系统，而是基于光线的系统。新型的光线捕获、处理和显示技术已经为FTV开发出来。这些技术也被用于实现全面的光线再现3DTV。MPEG技术促进了FTV的国际标准化。FTV的第一阶段是多视点视频编码，第二阶段是三维视频编码。本文对FTV系统及其相关技术进行了综述。
FTV (free-viewpoint television) is an innovative visual media that allows users to view a three-dimensional (3D) scene by freely changing their viewpoints. Thus, it enables realistic viewing and free navigation of 3D scenes. FTV is the ultimate 3DTV with infinite number of views and ranked at the top of visual media. FTV is not a conventional pixel-based system but a ray-based system. New types of ray capture, processing, and display technologies have been developed for FTV. These technologies were also used to realize an all-around ray-reproducing 3DTV. The international standardization of FTV has been promoted in MPEG. The first phase of FTV ismulti-view video coding and the second phase is 3D video. In this paper, the FTV system and its technologies are reviewed.
