optical distortion correction

基本解释

In addition to using the aberration correction theory, optical distortion can be corrected with the digital image processing technology.
光学系统的畸变除了利用像差理论来实现校正外，还可以利用数字图像处理技术来进行校正。
In this paper, firstly, the definition of optical distortion was introduced briefly and the theory of correction of distortion using dot-array plate was presented.
本文介绍了畸变的概念，讨论利用点阵样板进行畸变校正的理论；
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。
