g2o: A General Framework for Graph Optimization

In this paper, we describe a general framework for per-forming the optimization of nonlinear least squares proble ms that can be represented as a graph. We call this framework g 2 o (for general graph optimization ). Figure 1 gives an overview of the variety of problems that can be solved by using g 2 o as an optimization back-end. The proposed
