Real-time Merging of Real and Virtual Spaces by Dividing Object Space into Multi Layers Using Stereoscopic Chromakey-Imposer System

Abstract

In the field of Mixed Reality, one area of Virtual Reality, the method of merging virtual and real spaces have been often discussed. A chromakey-imposer is often used to synthesize CG and real images, but the relation between CG and real images is either in front or behind because a general chromakey-imposer has only one chromakey plane. To make one advance in the former method of merging we propose a method to make a visual effect as if a real space is embedded in a virtual space by dividing an object space into three layers and using two chromakey planes. We tested the visual effect by treating the object space as a studio space which has a large area and a desk space which has a small area.
