Re: Microsoft Kinect: infrared depth maps for dewarping?
Wow, that's actually a somewhat usable depth map. It's kinda jaggedy, but I suppose that averaging multiple slices would help. Can you try that and see what happens?

Re: Microsoft Kinect: infrared depth maps for dewarping?
Yeah, I will, but you can, too -- all the data I have are in those screenshots.
I'm going to start seriously analyzing the Kinect over the next few days, including explaining the tech in some serious detail. As a part of that, I will sample a bunch of books and try to provide you with some better data.

OK, great. Sorry I haven't been very responsive recently -- flights and work keep me away...

No problem, Rob. I'm also planning on getting you that Sharp sensor data we talked about. Just have to find my Arduino in this mess.
So, I posted a camera modification guide with some new images if anyone is interested... more Kinect data coming soon.

Science Friday has a segment on the Kinect this week. I left a link on their website back to this thread: http://www.sciencefriday.com/program/archives/201011196.

I picked up a Kinect, and have been watching the developers on Freenode #openkinect. Haven't gotten further than just testing it with my person, not even with a book yet.

Re: Microsoft Kinect: infrared depth maps for dewarping?
Cool!
I could use some help on the next plan. I'd like to save out the 11 bit depth data as a TIFF or maybe even some other kind of file- -rather than mapping it to colors, I just want the numbers directly. If you can help collect that data, it will help both me and Rob to make a little progress on dewarping. I'm working on another scanner this weekend and so I can't pay much attention to the Kinect for a few days.
What OS are you on?

Windows XP 32-bit, but it looks like the Kinect can be recognized from inside a VM as well, and I have Linux VMs handy, although I've only tried it on Windows so far.

The Windows driver isn't far off, and it will be good to have a Windows guy on things. Rob is on Mac, I'm on Linux/Win, and you're on Win. Should be best of all three worlds. For book scanning we don't need the full frame rate of the Kinect, either.

Re: Microsoft Kinect: infrared depth maps for dewarping?
Am I doing this right?
http://s3.amazonaws.com/vitorio/depthtest1.png should be a false-color RGB depth image.
http://s3.amazonaws.com/vitorio/depthtest1.tiff should be a 16-bit greyscale TIFF of the 11-bit disparity data.
The format I came across for point clouds (PLY) wants a conversion to a real-world coordinate. The DEM format looks like I could do it without that, but maybe this is enough for tonight.
