Adjust ransac cost function to optimise for better solutions #54

Closed jveitchmichaelis closed 2 years ago

jveitchmichaelis commented 2 years ago

Currently the cost function can cause ransac to find a local minimum with a low number lines (but low fit error). We should perhaps change back to just using the number of lines matched and also look at adding a cost term to encourage the fit to be more linear (e.g. an L1 norm of the fit coefficients).

Added an option to fall back to number of matches, with rms error as tie breaker (bfad6aef3d8ba1350a1c7e1c3d02c8319c167654) - closing for now.
