镜头变形及其建模是光学相机标定的一个重要因素。大多数标定算法都包括一个失真模型，以处理摄像机镜头引起的针孔摄像机模型的差异。然而，对于高精度的校准，必须使用复杂的失真模型，并且在校准过程中必须确定它们的许多参数。在这项工作中，我们提出了一种简单的、基于光滑薄板样条的非参数方法来校正透镜变形，并且具有很高的精度。
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.
