I saw a feature about Mercedes-Benz collision avoidance vision systems research on the Telly here in Germany where I am at the moment. 

 

This particular project uses two cameras to create stereo vision.  Comparing the two images is used to detect pixels that represent motion that could be hazardous to the vehicles current path.

Unfortunately, the clip above that I found on youtube doesn't have any explanatory voice-over, but appears to be the press-release footage.  Still, if you have enough patience to watch the video, keep an eye out for the display inside the car which shows the calculated threat motion vectors  

More about this, I do not know, but I thought it would be interesting for those looking at see-and-avoid systems for UAVs and the like

 

edit: just found this addional footage which shows the developer Uwe Franke describing the system in a little more detail - German and English sections follow each other

 

another little bit from Dr Stefan Gehring

Some background reading: http://www.deutscher-zukunftspreis.de/en/content/team-1-13

(Summarizing: SGM algorithm from DLR http://www.dlr.de/rm/en/desktopdefault.aspx/tabid-4847/8044_read-13... packed on an FPGA for low power consumption for use in cars)

Could be a nice (and more powerful) Kinect replacement, if they licence it for such an application... Mercedes cars are probably a bit too pricy just to take out the sensor :-)

yes, a system like kinect (or better) would be great for a mini uav.

I actually experimented with trying to connect a kinect up to an arduino last year using the sparkfun USB Host shield and the code from Circuits@home but found that the usb protocol could not be handled.  Definitely need an ARM processor running on a separate board to be able to handle the number crunching.

Interesting. I wonder what would happen if two cars like this would react when they are in a colliding path..

I didn't see anything about operation at night. 

Sure, they could be lit with infrared or maybe just the headlights would do, but you wouldn't be able to see everything. I wonder how that would affect their performance.
