Abstract: PURPOSE: A real time markerless 3D object tracking system for the augmented reality is provided to extract a feature point and express the object through the extracted 3D object feature point. CONSTITUTION: A feature point extraction unit(110) extracts a feature point from an object image. A descriptor generator(120) creates expression factor of a feature vector based on the extracted feature point. A matching unit(140) matches the extracted feature point with the feature point of a reference image corresponding to a preset 3D location information. A rotation and moving information tracking unit(150) traces the rotation and moving information based on the matched result.
