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

edit

I am using ROS Hydro on Ubuntu 12.04 with a Microsoft Kinect. From top to bottom, this is what worked for me:

sudo apt-get install ros-<ros_distro>-openni-camera
sudo apt-get install ros-<ros_distro>-openni-launch
sudo apt-get install ros-<ros_distro>-openni-tracker

Go to this Dropbox from isura (Thanks) and download NITE-Bin-Linux-x64-v1.5.2.23.tar.zip. Extract the zip and tar into a temporary folder (i.e., ~/tmp).

cd ~/tmp/NITE-Bin-Dev-Linux-x64-v1.5.2.23/
sudo ./install.sh

Ensure your Microsoft Kinect is properly connected, then run:

roslaunch openni_launch openni_launch camera:=openni

In a separate terminal window run:

rosrun openni_tracker openni_tracker

In another terminal window run:

rosrun rviz rviz

In Rviz, change Global Options > Fixed Frame to openni_depth_optical_frame.

"Add" the visualization (bottom left) PointCloud2.

Change PointCloud2 >Topic to /openni/depth_registered/points (but whatever you pick works).

"Add" the visualization (bottom left) TF.

Stand in front of the Microsoft Kinect and make the "Psi Pose". Axes should appear on all your joints.

I hope this helps you. There are a lot of different versions of NITE out there and this is the one that happened to work for me.

I find a solution in this link:

You need to use Sensor-Bin-Linux-x64-v5.1.2.1 rather than NITE-Bin-Dev-Linux-x64-v1.5.2.23

This is how i solved this issue, Firstly you need to make sure you NITE 1.5.2.23 installed on your system

Then run

roslaunch openni_launcher openni.launch

this is necessary for the tracker to work but the point is not include in the documentation

now, in a new terminal run

rosrun openni_tracker openni_tracker

you shouldnt get any error now for running it, check its working by standing in front for kinect and running rviz

I'm a new user of ROS openni . Now I am using ubuntu 12.04 and my ROS dist is groovy. when I run the command rosrun openni_tracker openni_tracker,the only thing I got is a error message: InitFromXml failed: Can't create any node of the requested type!

I followed the solution above provided but no use

I googled a lot ,but not a correct solution for me.Any help will be appreciated ,It really drives me crazy.

Thanks

I'm not sure which platform you're using but on my turtlebot, I experienced the same thing and found it occurs only when the power seems not be provided (light is off on USB cable that's connected to iRobot Create). I solved this issue by first running:

rosrun turtlebot_node kinect_breaker_enabler.py &

Adding license wasn't necessary for me. HTH.

Hi Antony,

I am facing the same problem., did you find any solution ?

Thanks D
