摘要

本报告描述了一个系统，该系统以实时交互速率将物理和虚拟对象合成到全景背景图像中。静态摄像机指向一个40厘米/sup 3/的微型舞台，其背景被涂成彩色绿色。用户可以在场景中添加虚拟对象，并通过使用一个由连接到基准标记的小杆组成的代理设备来操纵它们的参数。我们的系统在普通硬件上运行，比如配备火线摄像机的笔记本电脑。使用片段着色在GPU上实现了必要的色度键控和自适应差分抠图算法。

Augmented reality live-action compositing

This report describes a system that performs live-action compositing of physical and virtual objects to a panoramic background image in real-time at interactive rates. A static camera is directed towards a 40 cm/sup 3/ miniature stage, whose backdrop has been colored in chromatic green. Users can add virtual objects and manipulate their parameters within the scene by using a proxy device that consists of a small rod attached to a fiducial marker. Our system runs on commodity hardware such as a notebook equipped with a firewire video camera. The necessary chroma-keying and adaptive difference-matting algorithms have been implemented on a GPU using fragment shading.
