中文摘要： 基于异形大屏幕(半球、圆柱、弧形等)投影的立体真实感群体互动场景在军事训练、体育训练、产品展示、教育、娱乐等领域的应用越来越广泛。目前的显示系统多是基于固定视点渲染和显示场景画面，缺乏一定的真实感。 为此，本项目重点研究基于位置的多视角实时渲染与异形大屏幕投影的实时变形校正，群体用户位置跟踪与聚类等关键技术，使不同位置的用户实时观看到基于其所在位置和交互内容的不同画面，使得对于现实世界的模拟更真实；并研发群体虚拟射击系统进行技术集成和验证，为基于异形大屏幕投影的立体真实感群体互动场景的构建提供有效系统方案、关键技术和工具软件，推动人机交互与虚拟现实技术的深入研究和广泛应用。

英文摘要： In recent years, 3D realistic scene with crowd interaction on large screens of different shapes has been widely applied to the fields of military training, sport training, product exhibit, education and entertainment business. Most of current display systems are based on rendering and displaying the scene at a fixed view position, which only results in a sense of limited reality. In this project, our research faces 3D realistic scene with crowd interaction, particularly focusing on solving its core issues such as real time photo-realistic rendering and projected camera calibration for large screens of different shapes, trajectory tracing and crowd clustering. The goal here is to enable users receive different virtual experiences according to different view positions or different interaction contents, which in turn will raise the sense of reality to a higher level. In addition, we will provide effective system solutions and software tools for virtual crowd shooting based on 3D realistic scene with crowd interaction, which will promote the research of human-computer interaction and virtual reality in research depth and application width.
