2 Kinects 1 Box

First test of merging the 3D video streams from two Kinect cameras into a single 3D reconstruction. The cameras were placed at an angle of about 90 degrees, aimed at the same spot in 3D space.

The two cameras were calibrated internally using the method described in the previous video, and were calibrated externally (with respect to each other) using a flat checkerboard calibration pattern and manual measurements.

New software version with support for multiple Kinects is available for download at

is your software working in windows?

[okreylos]

Not natively. It runs under cygwin (the POSIX emulation layer) or under Linux inside a virtual machine, but in both cases performance will be very bad. Neither cygwin nor VMs get direct access to the host's graphics card, and OpenGL will fall back to software emulation.

Try this to reduce the interference between the two kinects

Yes, it's a very clever method. I'm focusing more on the software side of things, so I haven't tried it myself. I'm holding out for some Kinect 2.0 that comes in a variety of IR "colors" so that interference is solved for good.

hey, great video!

I thought you might be interested in this video:

/watch?v=CSBDY0RuhS4

it was made by microsoft R&D and it sloves the interference problems.

I hope you will watch this

[okreylos]

Yes, I saw that, and it's very clever. I haven't tried it because it's more hardware hacking than I normally do; I focus on the software side.

[okreylos]

So you started with a flawed premise (who said anything about xbox?) and jumped to a counter-factual conclusion (you're seeing it here, and I'm not faking it, ergo it must be possible). In other words, stating that you work for Microsoft was redundant.

Sorry, I kid. No offense. This was the perfect setup. :)

BUT WILL IT BLEND ?

[okreylos]

There is no hard limit on the number, but you need one USB bus per Kinect, and the more Kinects you add, the more interference between them you'll get. It's a matter of diminishing returns. The "shake & sense" method someone posted in the comments below is one way of reducing interference; ideally, Microsoft would sell the Kinect in a variety of colors. Normal users wouldn't care, but power users could buy a set of different colors, so they won't interfere with each other at all.

[Nestor Garcia]

Its possible to use more than 3 Kinects?
