Re: Microsoft Kinect: infrared depth maps for dewarping?

Okay, I tidied up the code. The Windows libfreenect work isn't there yet, and Zephod's drivers and C++ sample code aren't really made to be expanded upon (unless you like programming in C++), so I installed the closed-source Code Laboratories NUI Platform drivers and used their DLL: http://codelabor...

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-...

Re: Microsoft Kinect: infrared depth maps for dewarping?

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.

Re: Microsoft Kinect: infrared depth maps for dewarping?

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?

Don't both of these devices need to be centered above the subject matter in the same location? How does this work when you have 2 devices fighting for space to survey the same field? The Kinect has it's IR camera to the right of the IR projector, and the visible-light camera further offset to the l...

Re: Microsoft Kinect: infrared depth maps for dewarping?

It seems to me that the only reason structured light is employed is because the scene in question lacks texture in some areas. I don't see this as a requirement for our application, because those areas which lack texture are presumably areas of blank page, and can essentially be ignored. The only t...

Structured light for dewarping

Both the Kinect and the page-flipping demo use the same techniques for figuring out depth and alignment: structured light. http://en.wikipedia.org/wiki/Structured_light The links in the Wikipedia article include other references, such as using it to automatically align projectors (where I first hear...

Re: Post something about yourself here (The Hello Thread)

Hi, all, I'm here because there's a bunch of out-of-copyright design books that I'd like to liberate. :) I didn't see anyone here talking about it, so I ordered this book scanning platform to try it out and get my feet wet in this whole business: http://www.ponoko.com/design-your-own/products/digita...
