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):
