Kinect in ROS

I was tracking a person using Kinect for Windows in ROS. 

rosrun openni_tracker opennI_tracker

It worked well, until I tried install openni_launch by this command: 

sudo apt-get install ros-indigo-openni-launch

Now when I run 

rosrun openni_tracker opennI_tracker

I get this error: 

InitFromXml failed: Can't create any node of the requested type!

Things which I tried:

1.) sudo apt-get purge ros-indigo-openni-launch

2.) reinstall NITE version 1.5.2.23

3.) reinstall all kinect drivers

but nothing works.

I receive this error also when running that same command. I have installed openni_tracker differently using the instructions found here.

Getting all of these pieces working together on a random computer can often be a bit tricky! I wrote this answer a long time ago that is still my number one resource on how to get everything working together. A few other debugging points:

  1. If you can, try to avoid using USB 3.0 ports.
  2. If having issues, make sure that XnSensorServer process is not still running.
  3. Try unplugging the Kinect and then running sudo service udev reload. Plug back in and try again.
  4. Since you are using NITE 1.5.2.23, try installing the OpenNI SDK v1.5.7.10 from here

Sometimes the points from this answer can also be helpful.
