In this paper, we describe the method that recovers the projective motion of the camera using a planar surface from sequential images and makes the virtual camera, by which views of 3D graphic objects are generated, move according to the motion of the real camera equally. The proposed method has some advantages that enable the real and virtual coordinates systems to align without any calibration information of the camera and markers, register virtual 3D graphic objects on sequential images easier than general structure-and-motion systems. In addition, it is easily applied to 3D graphic tools such as DirectX because the recovered rotation matrix of the camera is orthogonal.
