- The primary geometric distortion in vertical aerial photographs is due to relief displacement. Objects directly below the centre of the camera lens (i.e. at the nadir) will have only their tops visible, while all other objects will appear to lean away from the centre of the photo such that their tops and sides are visible. If the objects are tall or are far away from the centre of the photo, …

- Deformation of a camera window pane is due to the pressure difference between the outer atmosphere and the interior of the airplane which carries the camera. The effect of this deformation on the geometric properties of aerial photographs is evaluated. Formulas are proposed to obtain exact and approximate values for the deflection of the rays passing through …
What is Lens Distortion? - Photography Life
- https://photographylife.com/what-is-distortion
- In photography, there are two types of distortions: optical and perspective. Both result in some kind of deformation of images – some lightly and others very noticeably. While optical distortion is caused by the optical design of lenses (and is therefore often called “lens distortion”), perspective distortion is caused by the position of the camera relative to the …
