Test Data & Visualization

A reference dataset is provided so you can verify a fresh install and explore the visual output in Rerun.

Dataset

The data was recorded by the TUM Autonomous Motorsport Team during the Abu Dhabi Autonomous Racing League 2025. It enables testing the georeferencing executable.

  • LiDAR / SLAM trajectory — created with glim.
  • Reference trajectory — raw data from the RTK-corrected GNSS signal of the vehicle.

Visualising results in Rerun

  • Results of the rubber-sheet transformation and the resulting, transformed point cloud map are streamed live to Rerun.
  • By default the Rerun viewer instance inside the Docker container is spawned. If you have issues with the viewer and your graphics drivers, launch a Rerun viewer locally instead — FlexCloud will connect to it automatically.
  • Adjust the algorithm parameters (see Usage) if results are unsatisfactory.
