Non-parametric Registration as a Way to Obtain an Accurate Camera Calibration

摘要

We present the SSD-ARC, a non-parametric registration technique, as an accurate way to calibrate a camera and compare it with some parametric techniques. In the parametric case we obtain a set of thirteen parameters to model the projective and the distortion transformations of the camera and in the non-parametric case we obtain the displacement between pixel correspondences. We found more accuracy in the non-parametric camera calibration than in the parametric techniques. Finally, we introduce the parametrization of the pixel correspondences obtained by the SSD-ARC algorithm and we present an experimental comparison with some parametric calibration methods.
