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。
2
The optical calculation and aberration correction are done.
并且进行了光学计算和像差校正。

In addition to using the aberration correction theory, optical distortion can be corrected with the digital image processing technology.
