ARTag Rev2 Fiducial Marker System: Vision based Tracking for AR
Abstract
ARTag is a fiducial marker system using passive computer vision introduced recently at ISMAR 2004. It uses square markers with digitally encoded ID's specially designed to bring false positives and inter-marker confusion rates down to near zero, and utilizes an edge-based approach for immunity to lighting and occlusion. A second revision is now available providing improvements and easy usage of ARTag into an application program with single or multi-marker arrays with OpenGL rendering.
