Camera Calibration: Basics

This lecture covers the fundamentals of camera calibration, including internal and external parameters, the number of measurements required, and the direct linear transform method. It also discusses the limitations of the pinhole model, imaging with a lens, thin lens properties, camera obscura, and aperture effects. The instructor explains depth of field, proof of image focus, changing focal length and aperture, distortions like chromatic aberration and radial lens distortion, and the use of lens systems to minimize aberrations.
