Hey from the back he's a hollowgram!!!!

...


sorry.

Multiple cameras, and you have something pretty cool.
..somehow, I have the feeling that the porn industry will be quick to jump on this.

The Porn industry is quick to jump on anything.

You mean like creating 3-d models of people you're stalking! Err wait, I have said to much.

porn industry? Think of the games man!

Wait, so this thing is actually a 3D camera that you put in your living room and hook up to a device built for image processing that's connected to the internet? Really?

Check out this totally awesome prescription muscle relaxer. It's called Soma.

His room looked even more depressing in 3D.

wow, my first top 15 video! awesome!

Not Penny's boat!

I think it was stated by one of these guys that multiple cameras is not possible yet because of the IR beam it projects. Adding in a second or third Kinect would disrupt the first one.

Either way, this is a fascinating piece of hardware despite the $150 price tag being a bit steep. However, to hardware hackers this is an insane bargain and a dream.

This video is the only information I have about Kinect or the 3D video scheme this guy has setup; so, take my opinion with a grain of salt, but I don't see how multiple cameras would interfere at all with the 3D mapping. As for multiple Kinects, it seems like you would just need to partition the IR bandwidth between the various devices -- that is if IR light sources with high enough chroma and IR sensors with narrow enough specificity for that exist.

Porn applications, yay... real sex is just so icky.

Trying to figure out why you are referring us to a prescription drug site
Prescription Drug Sites are the biggest Spammers on the internet - Why are you doing it??

Well actually it is the guy in this video that multiple Kinects in one room will not work because of IR-mixups:

(sorry about the reply on your profile page, the videosift user interface is too complex for me)

(jeebus, videosift ui is such a mess that I now have to edit this further, this was a reply but videosift won't let me actually quote the original messages without generating a big blob of html instead of the original messages)

Hmmm.. I think we are looking at this from slightly different perspectives. I wasn't talking about hacking the current version of Kinect, but rather wondering how close we were to cheap, mass-produced, 4D video from devices like this. Although, now that I think of it.. that 'major hardware hacking' that he refers to might just be changing the light source and the sensor. Even one additional unit operating on a different wavelength would give you a lot better coverage.

The Kinect apparently works by projecting an array of points into the room with the IR emitter, which is then captured by two cameras with a known spatial separation, and this data is used to estimate the 3d space. adding more cameras will not do much, since the IR projection casts shadows. Apparently the Kinect is already quite sensitive to environmental disruptions (sunlight being the most obvious example), so trying to narrow down the wavelengths used would probably just make things worse. A better idea might be to double the framerate of the cameras and sync up two emitters so only one is projecting at a time. I don't know if the hardware is capable of that, depends on the sensitivity of the cameras and the strength of the IR emitter.

hmmm.. good idea.

For completeness of the discussion, I thought I would add that the same guy has now gotten two kinects working together:

Quite amazing!!! So for the most part you are watching at a camera angle from where there is actually no camera at all, the image is calculated from two different camera angles.
