3D Mapping of a Collapsed Car Parking Lot
The following data was collected during NIST Response Robot Evaluation Exercise 2008 at Disaster City, Texas. The related map was generated using 3D Plane SLAM.

3D Plane SLAM Results
Below some videos are shown with animated results of the 3D mapping with 3D Plane SLAM. Please click the images to play the movies.
Plane-SLAM Maps in X3D format
The results of the Plane-SLAM are also available as X3D data. Use "tar zxvf file-name" to uncompress and untar into folders, and then load main.x3d in the output folder using an X3D viewer.

Comparison to ICP
3D-Plane-SLAM outperforms Iterative Closest Point (ICP) in this scenario in terms of computation speed and robustness. Due to the lack of meaningful odometry, ICP fails with several pairwise registrations.
