OpenNI human tracking from the ceiling with Asus Xtion Pro

I would like to track humans' path with an (later with many) Asus Xtion looking down from the ceiling.

OpenNI's sample program called UserTracker (which uses the User Generator node) would be perfect, if it recognized bodies from top view, but it can't. Because I don't need exact skeleton tracking, just to track basically any moving objects on the screen, I guess there's an easier way for this than rewrite the User Generator's recognition, as I saw it would be tough.
Maybe the Scene Analyzer node would be good for this, but I don't know how.

So anybody have an idea where should I start, which OpenNI classes should I use and how?
I searched a lot about this and got into OpenNI as I can, but I'm kinda new to it and it's so deep.

Thanks, Ts.

Solution

  • OpenNI: For learning how to use OpenNI, take a look at OpenNI Cookbook, and if you don't want to buy the book, you still can use the source codes implemented in the book here.

    OpenNI + OpenCV: If you want to use OpenNi and OpenCV together, you can follow this documentation. If you want a sample code, you can use this source code.

    Labeling + Tracking: For labeling and tracking the objects (in your case bodies), there are lots of implementations available online. As an example, for labeling, take a look at this thread. For tracking, you can use this example.

    For both labeling and tracking together, you can use this one.
