Build Status

Convert KITTI dataset to ROS bag file the easy way!

KITTI playback preview

TODOs

Help me make this feature rich and complete. Just fork this repo, implement new features (very easy in this case) and make pull request.

Feature request list:

  • make URDF of a car so transformations between frames are easily done by ROS itself.
  • deal with tracklets
  • support for unsynced+unrectified version
  • provide documentation via ROS wiki
  • provide simple GUI
  • distribute publically available bagfiles (is there a reliable public storage for this purpose?)
  • export only subset of sensors

Contributions

Thanks to the work of @jnitsch, kitti2bag can now export velodyne laser data and dynamic tf transformations. Thanks to @emreay-, this tool can now convert odometry datasets too. Thank you both!

How to install it?

It is very easy! Just run

pip install kitti2bag

How to run it?

One example is better then thousand words so here it is

$ wget http://kitti.is.tue.mpg.de/kitti/raw_data/2011_09_26_drive_0002/2011_09_26_drive_0002_sync.zip
$ wget http://kitti.is.tue.mpg.de/kitti/raw_data/2011_09_26_calib.zip
$ unzip 2011_09_26_drive_0002_sync.zip
$ unzip 2011_09_26_calib.zip
$ kitti2bag -t 2011_09_26 -r 0002 raw_synced .

That's it. You have file kitti_2011_09_26_drive_0002_sync.bag that contains your data.

Other source files can be found at KITTI raw data page.

  • pykitti is very simple library for dealing with KITTI dataset in python.
  • kitti_player allows to play dataset directly. No bag file needed. I found difficult to get it work. Some bug fixed can be found in my fork of kitti_player but still not good enough.
