本文描述了将逼真的遮挡效果整合到基于镜像的立体共定位增强现实显示系统中。通过在半透明镜子下面添加LCD面板形式的光阻挡装置，可以选择性地阻挡物理世界的视野，从而使虚拟物体完全遮挡物理物体。此外，通过移除在反射显示器上呈现的虚拟对象的区域，通过半透明镜子和透射LCD面板看到的物理对象似乎遮挡了这些虚拟对象。我们描述了该方法的控制原理，并提出了一种基于视觉的场景重建生成遮挡遮罩的有效算法。最后，给出了系统的第一个原型实现。
This paper describes the incorporation of realistic occlusion effects into mirror-based, stereoscopic co-location augmented reality display systems. By adding a light-blocking device in the form of an LCD panel underneath the semi-transparent mirror, the view on the physical world can be selectively blocked out such that virtual objects can fully occlude physical objects. Furthermore, by removing areas of the virtual objects rendered on the reflected display, physical objects seen through the semi-transparent mirror and the transmissive LCD panel appear to occlude these virtual objects. We describe the governing principles of the approach, and present an efficient algorithm for the generation of the occlusion masks with the use of vision-based scene reconstruction. Finally, a first prototype implementation of the system is presented.
