The supported models are shown in this table from the paper:
All the camera model-to-model regression functions are located under m2m_fit.
- Brown-Conrady (BC) -
fit_bc_to_rat.m - Kannala-Brandt (KB) -
fit_kb_to_rat.m - Unified Camera (UCM) -
fit_ucm_to_rat.m - Field of View (FOV) -
fit_fov_to_rat.m - Extended Unified Camera (EUCM) -
fit_eucm_to_rat.m - Double Sphere (DS) -
fit_ds_to_rat.m - Division (DIV) -
fit_div_to_rat.m - Division-Even -
fit_rat_to_rat.m
Note: the back-projection model used in the solvers (Division-Even) is referred in the code as Rational (rat) model, because the Division-Even model is an instance of the Rational model where all the coefficients in the numerator are zero.
