What is g2o?

g2o (general graph optimization) is an open-source C++ framework for optimizing graph-based nonlinear least squares problems. It is commonly used in robotics and computer vision for tasks such as Simultaneous Localization and Mapping (SLAM), Structure from Motion (SfM), and bundle adjustment. g2o provides tools for defining vertices (representing parameters to be optimized), edges (representing constraints or measurements between vertices), and optimization algorithms to find the optimal configuration of the graph.
