Abstract

We introduce a novel tracking system based on invisible markers which are created/drawn with an IR fluorescent pen. The tracking system consists of one scene camera, one IR camera, and one half mirror. The two cameras are positioned in each side of half mirror so that their optical centers coincide with each other. We track the invisible markers using the IR camera and visualize AR in the view of the scene camera. Thus, it works as a robust markerless tracking system. Experimental results are given to demonstrate the viability of the proposed system.
