Overview

This group of datasets was recorded with the aim to test point cloud registration algorithms in specific environments and conditions. Special care is taken regarding the precision of the "ground truth" positions of the scanner, which is in the millimeter range, using a theodolite. Some examples of the recorded environments can be seen bellow.

Where do I start?

You first need to determine which data suit your needs. For that, pick up a dataset in the table below based on your requirements. If you are not sure, we suggest to start with structured datasets as they are easier to visualize. There, you will be able to have a look at different screenshots and pictures of the scene, which will help you to understand better the abstract point clouds. Then, go to the section Downloads → Visualization Files and download the file globalMap.vtk. To easily view this type of file, we suggest to use Paraview (http://www.paraview.org/) because it is freely available for Windows, Mac and Ubuntu users and it is well supported by Kitware. Another advantage is that Paraview can handle large point clouds with information on points faster than Matlab.

Once you have selected the datasets you need, you can download files in local reference frame if you want to test registration algorithms and compare your result with pose_scanner_leica.csv, which contains the ground truth information. If you are doing environment modeling, meshing, etc., you can directly download point clouds in global coordinates.
