Lens Distortion Correction

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。

On account of four distortions such as signal lag, radial distortion, eccentric distortion and thin lens, etc. a precision distortion correction model is established.

新模型考虑了信号滞后、径向、偏心和薄透镜等四种畸变，建立了精确的畸变矫正模型。

Accurate measurement of geometrical distortion of image display system with wide-angle objective lens is the precondition and key of digital distortion correction.

准确地测量含有广角耦合物镜的图像显示系统的几何畸变是实现图像显示系统几何畸变数字校正的前提和关键。
