中文简介:
近年来,三维视频在研究和工业中都受到了极大的关注。应用范围从故事片中的特效到体育赛事的分析。 3D视频涉及在给定多个传统2D视频流的情况下虚拟相机位置的计算和场景的飞越。这种与视图无关的视频表示的高质量合成带来了各种技术挑战,包括采集,重建,处理,压缩和渲染。在这次演讲中,我将概述过去几年在ETH开展的这一领域的研究。我将讨论使用多个摄像机和投影仪组合的被动和主动采集3D视频的各种概念。此外,我将讨论与这些多个视频流产生的大量数据的表示和处理相关的主题。我将重点介绍从图形和视觉中获取知识的基础技术概念和算法。最后,我将展示一些针对体育广播虚拟重播的商业应用。
课程简介: In recent years 3-dimensional video has received a significant attention both in research and in industry. Applications range from special effects in feature films to the analysis of sports events. 3D video is concerned with the computation of virtual camera positions and fly-throughs of a scene given multiple, conventional 2D video streams. The high-quality synthesis of such view-independent video representations poses a variety of technical challenges including acquisition, reconstruction, processing, compression, and rendering. In this talk I will outline the research in this area carried out at ETH over the past years. I will discuss various concepts for passive and active acquisition of 3D video using combinations of multiple cameras and projectors. Furthermore, I will address topics related to the representation and processing of the massive amount data arising from such multiple video streams. I will highlight the underlying technical concepts and algorithms that draw upon knowledge both from graphics and from vision. Finally I will demonstrate some commercial applications targeting at virtual replays for sports broadcasts.
关 键 词: 三维视频; 技术挑战; 数据的表示和处理
