WebToday, SLAM is a highly active field of research, as a recent workshop indicates (Leonard et al. 2002). The first mention of relative, graph-like constraints in the SLAM literature goes back to Cheeseman and Smith (1986) and Durrant-Whyte (1988), but these approaches did not per-form any global relaxation, or optimization. The algorithm WebMar 16, 2024 · In fact, in recent years, one particular framework, pose graph optimization (or more generically, factor graph optimization) has become the de facto standard for most modern SLAM software solutions (like g2o or GTSAM). So, in this video, we are going to focus on understanding what pose graph optimization is and why it works. WebSep 27, 2024 · Simultaneous localization and mapping (SLAM) is an important tool that enables autonomous navigation of mobile robots through unknown environments. As the name SLAM suggests, it is important to obtain a correct representation of the environment and estimate a correct trajectory of the robot poses in the map.
