optical distortion correction

基本解釋

In addition to using the aberration correction theory, optical distortion can be corrected with the digital image processing technology.
光學(xué)系統(tǒng)的畸變除了利用像差理論來(lái)實(shí)現(xiàn)校正外，還可以利用數(shù)字圖像處理技術(shù)來(lái)進(jìn)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念，討論利用點(diǎn)陣樣板進(jìn)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(duì)稱的徑向畸變數(shù)學(xué)模型求出光學(xué)鏡頭的校正系數(shù)，對(duì)畸變圖像進(jìn)行校正。
