In fact, it is not like the film and moving the camera is similar to the place, but, with the film is a movement of the follower movement along the axisof the lens, it is relatively fixed picture.
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。

The application of GRIN rod lens is usually used with its core as optical axis, this is transverse application, and any analyze for vertical application is not seen.
