Rectification of single image.

Hi,

I have been looking at ROS calibration recently, and I came across the term "rectification" being used for single images ( see ROS image_proc and ROS image_geometry API for single camera).

My question:

From my understanding, the term rectification is used for stereo cameras/images. What does it mean for single cameras ? Is it the same is un-distortion of an image ?

Rectification process should be done in every image. All lens (cameras) have optical aberrations, therefore, rectification is always recommended for all inputs.
