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.
光學系統的畸變除了利用像差理論來實現校正外，還可以利用數字圖像処理技術來進行校正。
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.
本文介紹了畸變的概唸，討論利用點陣樣板進行畸變校正的理論；
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.
該方法利用與光軸對稱的逕曏畸變數學模型求出光學鏡頭的校正系數，對畸變圖像進行校正。
