Tracking: Implement Brown-Conrady distortion model
Implemented Brown-Conrady lens distortion model with 4 radial and
2 tangential coefficients to improve compatibility with other software,
such as Agisoft Photoscan/Metashapes, 3DF Zephir, RealityCapture,
Bentley ContextCapture, Alisevision Meshroom(opensource).
Also older programs: Bundler, CPMVS.
In general terms, most photogrammetric software.
The new model is available under the distortion model menu in Lens
settings.
For tests and demos check the original patch.
