Using the pi_tracker

Question

Using the pi_tracker

montess opened this issue 10 years ago · comments

I have downloaded and built this package but like you said it depends on skeleton_markers for the skeleton_tracker node. When I run the pi_tracker_lib.py node nothing happens I assume that this is the node that is for talking to the OpenNI skeleton tracking API and publishing the joint configuration and tf frames. Also, when I try and run any of the remaining nodes it sais ImportError: No module named skeleton_markers.msg. Im having a hard time trying to figure out what OpenNi skeleton tracking that you are referring to. I am fairly new to ROS and Im trying to display skeletal tracking and use the pi_tracker package for teleoperaton. My robot is running the ROSARIA package and It is ready to recieve commands published to cmd_vel. May you please offer me some advice.

Thank you

When attempting to open the openni_tracker node I recieved this message. I have installed Nite But I am still getting the message: NITE is likely missing: Please install NITE >= 1.5.2.21. Check the readme for download information. Error Info: User generator failed: Can't create any node of the requested type!

For the ImportError in your first post, be sure to run "source ~/catkin_ws/devel/setup.bash" in each new terminal you open or put this command at the end of your ~/.bashrc file.

For your comment regarding NITE, please see http://answers.ros.org/question/130891/problems-with-openni_tracker-launching for a similar problem. You will probably have to manually install NITE 1.5.2.23. The link in the answers.ros.org answer is no longer correct so you can try:

After unpacking the NITE distribution, move into the distribution folder and run:

$ sudo ./uninstall.sh
$ sudo ./install.sh

Hi, I have URDF robot model which I can see on Rviz and I can get tf data from kinect and visualize that data on Rviz too but I don't how to combine them. I would like my robot model to move according to the data it gets from kinect. I thought you are experienced in this. Could you please help me on this? Thank you very much!

Sorry for the delay in responding. Unfortunately I am no longer maintaining this package but you can find the documentation on the ROS Wiki at http://wiki.ros.org/pi_tracker. At the bottom of that page you'll find example launch and yaml files.
