Lens distortion

The following lens distortion models are supported in SURE:

  • BUNDLER (2 parameters),
  • VISUALSFM (1 parameter),
  • BROWN5 (5 parameters),
  • IWITNESS (5 parameters – a variation of the Brown model),
  • INPHOCOEFF (12 parameters),
  • INPHORADIALGRID,
  • INPHOGRID.

Orientation files can state lens distortion parameters. In the following example (from an .ori file), the Brown model contains 3 radial (K1,2,3) and two tangential parameters (P1,2):
