We just started a semester-project concerning an interactive dance performance. We would like to track the dancers skeletons (up to two) on the whole stage with kinects. The stage is not that big, so three kinects in a row with slightly overlapping frustums should be enough.
We already did some tests with one kinect and the OpenNI-Kinect nodes of vvvv.
So, now my question: What do you think is the best way to use 3 kinects to get a continuous tracking of the whole stage?
I think there are two approaches:
Using one mashine for every kinect, merging all the informations on one of these mashines and distilling only two skeletons out of it. That’s quite expensive just for the tracking…
Using one machine for all kinects. Cheaper and probably more comfortable, because we don’t need OSC or something else to bring the data together. BUT: I read that it would be difficult to use OpenNI with more than one kinect. Are the Microsoft nodes perhaps the better choice?
Did anybody experiment with that already? Thanks for any advice.
