Most existing 2D video stabilization methods may fail to estimate the motion parameters of cameras. In order to solve above problems, we propose a video stabilization method based on 3D technology. Firstly, recovers the original 3D camera motion using the structure-from-motion system. Then, a virtual camera path is computed by polynomial curve fitting. And then, smoothes the view orientation by vectorial interpolation. Finally, corrects the frames which selected in conformity with the smooth- ing location and orientation of cameras. Our experiments on stabilizing challenging videos of real scenes demonstrate the effectiveness of our technique.
