摘　　要：真人与虚拟角色的交互镜头是传统视觉特效影片制作中的一大难点,如何既能在视觉上形成匹配,又能有效展现出令人信服的角色互动感,是视效工作者追求的目标,利用动作捕捉和电影虚拟化制作技术来实现拍摄现场的实时交互与实时监看,无疑为这一问题带来了有效的解决方案。本文对电影虚拟化制作中的若干实时技术进行了介绍,并利用OptiTrack动作捕捉系统、Unreal三维实时渲染引擎、Ncam摄影机跟踪系统、Qtake现场视频处理系统,配合若干第三方插件支持,实现了真人与动作捕捉角色的实时交互、实拍画面与虚拟内容的实时合成与记录。The interaction between actors and virtual characters is a major difficulty in the production of traditional visual effects, as visual match and convincing interaction are goals pursued by visual effects workers. The use of motion capture and film virtualization production technology to achieve real-time interaction and real-time monitoring of the shooting scene has undoubtedly brought an ef- fective solution to this issue. This paper introduces several real-time technologies in film virtualization production, uses OptiTrack motion capture system. Unreal 3D real-time rendering engine. Ncam camera tracking system. Qtake live video processing system, a-long with a number of third-party plug-in support, to achieve real-time interaction between real people and motion capture charac- ters. real-time pictures and virtual content real-time composition and recording.
