optical axis of symmetry的意思|示意

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。

The principle of holographic ct measurement is introduced briefly, and to the reconstruction of axis symmetry field measured by optical ct, zoned method is discussed.

简要讨论全息CT测量原理，针对光学CT测量中轴对称场的重构问题讨论了环带法。
