hdl_graph_slam: real-time 3D LiDAR SLAM
How the pipeline works
1NDT scan matching
2Odometry
3Loop closure
4Graph optimization
NDT vs ICP scan matching
NDTused here
Per-voxel normal distributions
Robust to outliers
Handles density variation
ICP
Iterative closest point
More sensitive to noise
Flexible constraints and sensors

Classic SLAM still powers robotics
AI NEWS BLITZ
An open-source ROS package for real-time 3D LiDAR SLAM is drawing renewed attention.
