Introduction to 3D SLAM with RTAB-MapRTAB-Mapping, short for Real-Time Appearance-Based Mapping, is a graph-based SLAM approach. Appearance-based SLAM means that the algorithm…Jan 13, 20213Jan 13, 20213
A brief introduction to GraphSLAMGraphSLAM is a SLAM algorithm that solves the full SLAM problem, i.e, the algorithm recovers the entier path and map instead of just the…Jan 12, 20211Jan 12, 20211
An application of Numerical Solutions to Maximum Likelihood Estimation in GraphSLAMIn the previous post, we looked at a robot taking repeated measurements of the same feature in the environment. This example demonstrated…Jan 11, 2021Jan 11, 2021
Application of Maximum Likelihood Estimation in GraphSLAMAt the core of GraphSLAM is graph optimization — the process of minimizing the error present in all of the constraints in the graph. Let’s…Jan 11, 20211Jan 11, 20211
