Expose low resolution matching scores. ( #470 )
...
This is needed in preparation of adding a low resolution score histogram.

Also check low resolution match for 3D loop closure. ( #468 )
...
Related to #369 .

Use multi-res scan matching for loop closures too. ( #374 )
...
Improves loop closure scan matcher refinement.

Also use fixed covariances in 3D SLAM. ( #308 )
...
This follows #307 .

Remove 2D scan matcher covariances. ( #307 )
...
This replaces the scaled covariances derived from the Ceres
scan matcher by directly configurable weights. Using covariances
did not provide the expected benefit, and replacing the scaling
matrix by two values will allow a faster evaluation of the cost
function in the future.

Remove covariance from the 3D Ceres scan matcher. ( #200 )
...
Instead of passing around fake covariances generated by the scan matcher,
we introduce appropriate values where they are needed.

Remove the 'log_residual_histograms' option. ( #166 )
...
This option only existed in 2D. Also other refactoring to make the 2D
sparse pose graph optimization more similar to 3D.

Improve the sparse pose graph optimization. ( #165 )
...
Removes the loss function for intra-submap constraints in 3D SLAM,
as it is already done in 2D. Also removes a duplicate call to the
solver in 2D, and code cleanup.

Remove the UKF from local 2D SLAM. ( #140 )

Changes default configuration to log loop closure matches.

Consistently name weight parameter. ( #116 )
...
All parameters scaling optimization residuals to determine relative
importance are now consistently named.

Allow continuing after running a "final" optimization. ( #109 )
...
And a tiny cleanup of the submap visualization query.

Remove the 'also_match_to_new_submaps' option. ( #29 )
...
Instead, using a different constraint_builder.sampling_ratio is preferred.

Remove covariance computation from branch-and-bound. ( #27 )
...
These covariances were only used in 2D and are only an estimate.
Following 3D, we change 2D to use the (local) covariance computed
using Ceres.

Removes max_covariance_trace option. ( #25 )
...
This option is no longer really useful to predict outliers.
It is removed and other parameters scaled to minimize the change
in behavior. And related cleanup.

Optimize only once per submap in 2D. ( #22 )
...
The setting was unintentionally set to optimize twice per submap which
harms parallelism.
