The method USES the model of radial nonlinear distortion with the symmetry of optical axis to obtain correction coefficients of the optical lens, and then corrects the distortion image.
该方法利用与光轴对称的径向畸变数学模型求出光学镜头的校正系数，对畸变图像进行校正。

Radiallensdistortion coefficient can be obtained by linear algorithm in the calibration.
在标定过程中，应用线性算法求解出了镜头的径向畸变系数。
