Hello,

I tried 2 kinect a couple of times now and I have tried the following setups:

2 cams on same height pretty much at 90 degrees

2 cams on very slightly different hights at 180

I was trying to capture a movement which involves me turning around and when i turn i loose tracking on an arm, the arm is always seen by 1 cam (on the 180) but it did get a little hidden on the 90 (well i can see how it lost tracking as the hand moved near a static object..)

But im interested to know why the 180 degree one didnt work well, i was not near any other objects and so i thought it would be ok.. so my question is as im quite new to this is what is your ideal setup for capturing a movement where i need to turn around?

THanks

In my experience, Kinects at 90 degrees has worked better. My guess is that you have less IR interference when the cameras are not pointed directly at each other. Also, at 180, the data quality gets weaker as you move away from one device and stronger towards the other and with the 90 degree setup, the data quality stays more a little more even between devices. Be advised that I'm just guessing--I don't know if my observation actually means anything to the software. But, FWIW, I've had much better luck tracking 90 degree data.

BTW, when the Kinects are at 90, you can get nearly full coverage because you're recording an actual 3D image from each camera. Where tracking might fail is if you completely turn away from both cameras and crouch down and hold your hands close to your body, making sure to occlude them from camera--but if that's the motion you want to capture, you're better off turning your performance around to face camera. No point making the process more difficult than necessary. :)

Hope this helps.
