I've got three Kinects (1473's) running successfully with ROSHydro and Ubuntu 12.04. I can access streams for all three.

What I want to do is be able to get a complete recording when running experiments in our lab. To that end, I need the three cameras calibrated. However, it is likely we would want to shift their positions, so instead of a static universal frame I want to have them all calibrate to one object.

I've tried gitcloning RGBDemo from here: http://labs.manctl.com/rgbdemo/index.php/Documentation/MultipleKinect and can't figure out how to get it to work but I believe this is one option. Are there are specific commands for this in either OpenCV, PCL, or ROS itself? I was exploring using RViz but wanted to see if there was an easier way.
