Mysteries of the skeleton trackers

edit

Hey folks,

we are currently looking for a skeleton tracker we can use in our ROS project. We found these

• skeleton_markers -> works only with indigo, not with kinetic and is in “end-of-life”
• openni_tracker -> does not even work with indigo
• other stuff like the Chaos84/skeleton_tracker are oftern many years old as well and very poorly documented

What happened to them? Did they simply get out of fashion because something else replaced them or some companies bought some technologies (Apple)?

Do you know of a well maintained skeleton tracker already integrated in ROS or outside?

Thanks!
