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

Question

I'm trying to use the openni_tracker node in the openni_kinect stack but when I try and run it I get the following error message:

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

I'm using ros-diamondback and I'm trying to use openni_tracker with the kinect. This is really frustrating because I already had it working. Any help on why I'm getting this error would be appreciated.

Also, because openni_tracker doesn't display a view of the camera's image I was wondering if there was an easily accessible node that could display the skeleton tracking image tracker is based on.

Thanks

Anthony

You need to register the license key for the dev modules.

"sudo niLicense -l 0KOIk2JeIBYClPWVnMoRKn5cdY4="

The command itself worked for my turtlebot/Ubuntu, with exactly the same values without double-quotation, showing PrimeSense being associated with the key. However I still get the same error.

Answer 2

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 also meet the problem:

 NITE is likely missing: Please install NITE >= 1.5.2.21.

But when I remove and reinstall the NITE and Sensor and change the usb port by many times, it worked. I just run two commands:

roscore  
rosrun openni_tracker openni_tracker
