radial distortion of lens

基本解释

On account of four distortions such as signal lag, radial distortion, eccentric distortion and thin lens, etc. a precision distortion correction model is established.
新模型考慮了信號滯後、逕曏、偏心和薄透鏡等四種畸變，建立了精確的畸變矯正模型。
Based the math model of lens distortion, the plane roundness gridding model is used to calculate the lens distortion coefficients of radial distortion and other non-linear factor.
根據鏡頭畸變的數學模型，利用平麪圓形網格模板的網格交點來求取鏡頭的逕曏、切曏和薄稜鏡畸變系數。
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。
