im researching the MS Kinect device, to give my flying bot some vision. But i dont know how or if the kinect can be run via microcontroller or if it has to berun from a X86 type lame machine...? id like to get it running off a embedded microprocessor if possible.
EDIT: so far the web sources dont seem all that great, if some one knows of a good credible source please post it here. im searching diydrones too. So far, it looks like it has to report to a conventional computer, and im not wanting to drag one of those around the sky.

OpenNI PPA built lib (should have the Git url for local builds): demo:
ROS module: Built info for 1.15GHz SheevaPlug ARM board: Note the stability issues some people have reported:
Low level driver lib with SLAM support:
People normally use a powerful computer to run this type of mapping system. However, some simply relay the streams of information over a light-weight wireless-USB-cable-adapter or router (about 100m range). Few routers will natively support these types of USB media devices, but writing a client proxy stream server should be easy.
Note a used Dual-core mini-Netbook with a broken LCD is very inexpensive...

yeah but my professors think its "lame" to strap a laptop to a machine needing some computational ability... but wifi is what everyone else uses to link the drone to the desktop. id rather use my STM32F4 if possible.

You are likely going to have to get something a little more powerful if a 1.15GHz chip is choking on the bandwidth. Your board is perfect for control problems, but will be unlikely to handle the data.
I have seen quite a few people get caught by the build-it-from-scratch curse. Some students end up trying to fix driver issues, erratic hardware glitches, power failures, and non-repairable system failures.
These guys made it work, but fell for the "easy" sonar scam: Papers:
LOL... seems like they did it the easy way too...
Here are the ROS packages in the videos (note link 1 uses ground estimation so in theory an IMU is secondary):

cheers,
LOL !!! you keep calling Sonar a "SCAM" lol!!! ok its error prone, but not uselesss dam it, and i already spent my pizza money!
im not wanting to build it entirely from scratch, im willing to use existing libraries for C and C++.
(PS -> the unexpected ultrasonic " departure, resulting in fatal deceleration " did cost me $190 US for new gyros.)

Please tell us what you learn. Is there a developer's kit available?
Just a couple of months ago, I saw a lecture by JDSU about the vision system they developed for MS Kinect. Perhaps the first commercial application for "gesture recognition" technology. IIRC, to track a user's hands against a cluttered background, they illuminate the scene with the Kinect's own IR laser. Distance detection is based not on light transit time, but on patterned illumination and parallax measurement. Not sure how much of the image processing depends on dedicated hardware.
At distances greater than a few meters, it might be no more useful than a plain camera.

i have not found anything as far as an official dev thingie. but ill report everything here, and yes the laser has a dot making filter over it. so yes it projects dots and then uses line-by-line scan comparisons. i wonder how much of the processing is done on the kinect.
im still researching it, optical flow processing is really complicated and im already thinking of graduate level ideas i want to explore over the next 3-5 years.
Someone hacked a MS Kinect, attached it to a controller which was attached to a Tesla Coil. The results were so cool, a person could move their body around, and control the sound of the coil.
