Mixed Reality(MR) is a techunique which mixes virtual images with real images. We have two methods for realization of the MR,which are called video see-through and optical see-through. Visualizing occlusion between virtual images and real images has not realized in optical see-through MR. We realize optical see-through Mixed Reality which has occlusion between real images and virtual images mutualliy by measureing 3-D shape in real-time.
