This paper proposes a technique that uses a planar calibration object and projective constraints to calibrate parametric and non-parametric distortions. An iterative surface fitting is first used to constrain a B-spline distortion model by fusing the corrective distortion maps obtained from multiple views. The model is then refined within the whole camera calibration process.
