- Classical methods of camera calibration use an calibration object:
- Projection of each point gives us two equations and there are
11 unknowns. 6 points in general position are sufficient for
calibration. More points facilitate robust estimation using
non-linear least squares.
- Real cameras often have radial distortion.
