Please excuse me if this is not the proper place to ask this. I just need some general advice.

I have set up a very basic homemade motion capture system where I put three TrackIR cameras from NaturalPoint in a three fixed positions. I want to capture movement of a single object in three axis. So I laid out two of the cameras on both sides of my working area, plus the third camera above the object, pointing downwards.

I then use reflective markers to track the position of my object in the cameras.

I don't do any calculations on my system aside from a simple coordinate transformation from that of the real world to that of my virtual world. I do this separately, for each of the cameras. Since they are in fixed positions I already know how movements translate from one "world" to the other.

Is there any way that I can improve my mo-cap system? Should I apply some kind of triangulation (isn't triangulation implicit in my system already, given that Im using fixed positions for my cameras)? What filtering could I use to account for punctual lost of tracking elements?

Note that I want (ie. need) to stick to my current hardware.
