有理径向畸变模型及其解析解
Rational Radial Distortion Models with Analytical Undistortion Formulae
摘要：
径向失真的常见方法是通过多项式近似，它引入失真的具体参数到相机模型，并需要这些失真参数的估计。径向畸变估计的任务是找到一个径向畸变模型，允许容易的失真以及令人满意的精度。本文提出了一类新的有理径向畸变模型，并给出了易于解析的无畸变公式。实验结果表明，这类合理的径向畸变模型，取得了令人满意的和可比的精度。
英文摘要：
The common approach to radial distortion is by the means of polynomial approximation, which introduces distortion-specific parameters into the camera model and requires estimation of these distortion parameters. The task of estimating radial distortion is to find a radial distortion model that allows easy undistortion as well as satisfactory accuracy. This paper presents a new class of rational radial distortion models with easy analytical undistortion formulae. Experimental results are presented to show that with this class of rational radial distortion models, satisfactory and comparable accuracy is achieved.
