| Abstract: | A new algorithm is presented to determine infinite homography matrix and camera intrinsic matrix parameters under one camera motion set from the matched-point sets on two orthogonal planes.The camera intrinsic matrix with five parameters is obtained through eigen value decomposition of the infinite homography matrix.Based on the different methods obtaining epipole,three techniques are provided and compared.Experiments demonstrate that the new algorithm is feasible and robust. |

| Keywords: | homography matrix epipole orthogonal plane camera self-calibration |
