Free-viewpoint Video for Interactive Entertainment Production

这项提议的目标是实现足球或田径等户外体育赛事的转播质量免费视点视频。这项研究是由BBC R&D牵头的DTI技术计划下的一个合作项目，汇集了广播制作、视觉重建、视频分析和渲染方面的丰富经验。该项目将提供和评估用于现场直播体育动作回放的广播制作的自由视点视频技术，并展示该技术在家庭平台上互动可视化体育赛事的潜力。萨里大学的主要科学和技术目标分别由EPSRC和DTI支持：-开发具有广播视频质量的现场体育赛事的自由视点视频的算法(EPSRC)。-在消费游戏平台(DTI)上演示交互式自由视点渲染。调查人员最近的研究首次展示了基于工作室的自由视点视频的制作，该视频移动的人的视觉质量可与使用多个宽基线静态摄像机捕获的视频相媲美。提出的研究的挑战是开发健壮的计算机视觉和基于图像的绘制算法，以实现在光照变化的非受控室外环境中的自由视点绘制。

The goal of this proposal is to achieve broadcast quality free viewpoint video of outdoor sports events such as football or athletics. This research is a collaboration project lead by BBC R&D, under the DTI Technology Programme, which brings together extensive experience in broadcast production, visual reconstruction, videoanalysis and rendering. The project will deliver and evaluate free-viewpoint video technology for broadcast production of action replays for live sports and demonstrate the potential of this technology for interactive visualisation of sports events on a home platform. The principal scientific and technological objectives for the University of Surrey, to be supported by EPSRC and DTI respectively, are: - To develop algorithms for free-viewpoint video of live sports events with broadcast video quality (EPSRC). - To demonstrate interactive free-viewpoint rendering on a consumer games platform (DTI).Recent research by the investigators has demonstrated for the first time studio-based production of freeviewpoint video of moving people with a visual quality comparable to captured video using multiple widebaseline static cameras. The challenge of the proposed research is to develop robust computer vision and image-based rendering algorithms to enable free-viewpoint rendering in uncontrolled outdoor environments with changing illumination.
