Camera calibration is the process of estimating different parameters like intrinsic and extrinsic.

There are two types of camera calibration parameters –

  • Extrinsic
  • Intrinsic

There are two extrinsic parameters –

  • Rotation and
  • Translation.

Unlike extrinsic parameters, there are three intrinsic parameters-

  • Focal length
  • The optical center or principal point
  • Skew co-efficient.
