4. Lens Distortions

Chapter H. General Optics in I. Basic Principles discusses lens characteristics, basic optical relationships, and distortions. Those relationships and distortions apply to the lens system of an aerial camera. When a camera is calibrated its radial and tangential imgae displacements are determined across the entire focal plane.

Figure I-11 is an example of radial lens distortion calibration data for a camera.
