| Abstract(in English) | In this paper, we propose a camera pose estimation method which can deal with camera zoom. In the proposed method, the camera pose and the intrinsic camera parameters are estimated by minimizing an energy function based on the epipolar constraint. The key idea of the proposed method is how the parameterization of intrinsic camera parameters change with the zoom value. In a simulated environment, we show the effectiveness of the proposed method by quantitative evaluation of its accuracy. In addition, in the real environment, a CG object is overlaid by using the proposed method. From the result of this experiment, we confirmed that the proposed method can achieve accurate camera parameter estimation even while zooming. |
