Lens distortion and its modelling is an important factor for the calibration of optical cameras. Most calibration algorithms include a distortion model to cope with the discrepancy to a pinhole camera model induced by the camera lenses. However, for high-precision calibration sophisticated distortion models have to be used and their often numerous parameters have to be determined during calibration. In this work we present a simple, nonparametric method based on smoothed thin plate splines for correcting the lens distortion with a very high precision.
