How to combine multiple sensors over network to track user through it? (Not a bug..) about niwrapper.net HOT 2 CLOSED

This is not a bug in the wrapper as I see it. Perhaps you can continue the discussion on mail with @falahati? I don't even know if this is possible as the structured light projected by devices will disturb each other.

Yes, as Vidstige told, projected lights from each device make other ones confused. But there are ways you can solve this problem,

1. Disable projection of all other devices when capturing with one of them
2. Do what Microsoft did, shake each of devices a little. (Shake n Sense)

But then, about your question.
You need to define a 3D environment and merge data coming from each device. You also need to find a way to calibrate them too (triangulation and trilateration). For example check position of specific objects and find position of cameras related to each others so you can merge their data better.

But OpenNI or this wrapper are not going to help you in your way. You need to write an other library in top of this library and handle transferring, calibration and merging of data yourself.
But actually this is a good Idea, I may write something like it some day.
