카메라 줌 변화에서 3차원 물체의 실시간 증강현실 구현

This paper presents a real augmented reality system with camera zoom changing input image sequence. As camera zooming happens, undesired problems occur such as scale mismatch and vibration etc. because of assumption that camera internal parameters are constant. For overcoming these problems, we calibrate camera parameters using 3D control virtual objects. Experimental results show the proposed system can robustly perform augmented reality in real-time even if camera zooming changing happens.
