If Image Distortion的意思|示意

Better estimates of lens distortion and focal length will be obtained if the grid is positioned accurately over as much of the image space as possible.

更好的估计和焦距的透镜畸变能获得网格定位准确在尽可能多的图像尽可能的空间。

Straight lines in the three dimensional world must project to straight lines in the image plane, if the distortion is compensated effectively.

在畸变得到有效校正的前提下，三维空间中的直线投影到图像平面上应该是直线。
