SRRG2-SOLVER

Basic solver specifically designed for SLAM pipelines. Highly efficient, no fancy stuff, but man if it runs! :D

This repository contains several Catkin packages:

1. srrg2_solver: the barebone srrr2-solver package. Provides batch optimization with BOSS graphs, conversion of graphs from/to g2o format to/from BOSS format, and all other solver modules (most used variables and factors, linear solvers, iteration algorithms, robustifiers, termination criteria ... ). Minimal build dependencies are required.

2. srrg2_solver_extras: provides additional variables and factors (e.g. the AD version of the factors in tha package srrg2_solver). Minimal build dependencies are required.

3. srrg2_solver_experiments: provides comparative examples with pcl - based point registration.

4. srrg2_solver_gui: super experimental package that includes a graph viewer (works only with standard pose-graphs now). Requires OpenGL, QT, QGLViewer.

To know more about those packages, refer to the readme file in the respective packages.
