Multiple skeleton detektion("user-generator") by multiple kinects by OPENNI_TRACKER

edit

Dear friends,

I am new in ROS and OPENNI,

I achieved to launch two same node of the "openni_tracker" (tracker) by two different Kinect by using roslaunch file.

But the problem is that the "openni_tracker" just generate one SKELETON, so I am searching a way that I could relate the "xn::UserGenerator" to each of the Kinects (for example one UserGenerator for Kinect_1 and one different UserGenerator for Kinect_2).

• List item Do we have some limitations for using two different Kinects(camera) and definning different UserGenerator? (as this Link : https://github.com/OpenNI/OpenNI/issu... )
• List item Do you have any idea how I could do this?

Thanks
