The same thing happens even if I set the information matrix as a multiple of I matrix (to increase the uncertainty in 6D parameters). The library also provides for several easy-to-use interfaces in order to define planar graphs that are common in computer vision applications. Keywords: bundle adjustment SLAM optimization multi-robot decentralized distributed optimization least-squares ceres computer vision Description In State-of-the-Art decentralized mapping methods, optimization (correcting odometry drift) is typically done using pose graph optimization due to the fact that a pose graph is a very compact. , g2o [6], Ceres [7]) which can detect and optimize loops to build a globally. To derive the Laplace transform of time-delayed functions. Workshop on Graph Classes, Width Parameters and Optimization Prague, October 17 - 19, 2005 Organized jointly by DIMATIA and ITI. The general idea of factor graphs is to describe the state estimation problem as a graph of nodes (the state variables) that are connected by factors (measurements). By default, odometry is weighted into global optimization similar to local slam (scan matching) poses.
