In this paper, we propose an algorithm for hierarchical reconstruction. The affine projection is used to approximate perspective projection; the projective depths are iteratively estimated by linear iterative method. And then, the projective reconstruction is obtained by SVD of the measurement matrix. The intrinsic parameters of camera are computed by the homography of scene plane to the image plane, finally a 4x4 non-singular matrix is evaluated, which satisfies the conditions of Euclidean reconstruction. This matrix can transform projective reconstruction into Euclidean reconstruction. The result indicates our method is efficient and robust.
