lidarslam_ros2 v0.2.2

This is the public v2 beta patch release for lidarslam_ros2.

Date: 2026-03-28

Highlights

  • keeps the 0.2.1 public beta scope and refreshes it as a patch release
  • fixes cross-distro CI drift so the public release path is green on both Humble and Jazzy
  • keeps GNSS-weighted graph optimization, packet-path IMU deskew hardening, dynamic-object filtering, and classic-path fallback evidence aligned with the checked-in reports

Public Snapshot

  • fixed public entrypoint: bash scripts/run_autoware_quickstart.sh
  • map-authoring summary: python3 scripts/generate_map_authoring_report.py
  • place/classic closeout: python3 scripts/generate_exploration_closeout_report.py
  • NTU VIRAL current default APE RMSE: 0.952 m
  • NTU VIRAL best observed APE RMSE: 0.870 m
  • MID360 current default cross-validation APE RMSE: 3.641 m
  • MID360 best observed cross-validation APE RMSE: 3.590 m
  • comparison page: docs/comparison.md

Supported Scope

  • ROS 2 LiDAR SLAM with a non-GPL default path
  • pointcloud-map generation for Autoware-compatible workflows
  • map_projector_info.yaml output as Local without GNSS and LocalCartesian with a stable GNSS origin
  • release-readiness, map-authoring, dynamic-filter, and exploration-closeout reports from collected local artifacts

Known Limits

  • lanelet generation is out of scope
  • MID360 evidence is still cross-validation against GLIM, not ground truth
  • classic-path improvements remain fallback-path evidence, not the main public workflow
  • place-recognition descriptor experiments are documented, but the public default still relies on the distance-based path

Recommended Entry Points

bash scripts/run_autoware_quickstart.sh
bash scripts/run_rko_lio_graph_benchmark.sh
bash scripts/run_release_readiness_checks.sh --ape-threshold 0.10
python3 scripts/generate_map_authoring_report.py
