Key Terms
Optical Aberration: errors in an image that occur due to imperfections in the optical system, more specifically when an optical system misdirects an objects rays.
Distortion: a commonly used term in modern day photography that refers to any deviation from rectilinear projection and therefore is a form of optical aberration. Though distortion comes in a wide range of patterns and irregular forms, the most common types we see are "Barrel Distortion" and "Pincushion distortion".
Geometric Calibration: determination of the geometric relation of the imaging process of a camera
