Prop Vision.

So, I was reading a thread about Quadrocopters and I god to thinking about how the best way to hold them into position.
This got me thinking about·optical mice. Obviously there must be some quasi vision system that "sees" small movements on a surface and returns the motion back to the computer.
What if you took some vision chip that you could read like memory and started reading bands of data so that you could aproximate motion? Seems black/white would be a good choice. If you could convert intensity spots as a way to see if the craft is moving, you might better hold it in position.· Even low res would seem fine for this.
Has anyone tried this here? Anyone have suggestions?· Also if someone knows of a good video chip for such an experiment I would appreciate it.· I would think a video chip that you could read the memory directly would be best.
Thanks,
Peter

PhiPi has also done motion sensing using his "PropCAM", but he never got around to releasing it (even though he spent shed loads on lenses and sensors!)

You'll always have as many take-offs as landings, the trick is to be sure you can take-off again

However, usually you only get 18 x 18 pixels. If you want to scan more distant than one or two millimeters than you alos have to assemble the optics. I will look at MT9M001 / MT9M031 sensors delivering digitized megapixels at reasonable speed and moderate price - if your interface can handle the data rates.

I still have some PCBs, robot frames and the parts for the mouse sensor (although I'm out of almost everything else.

haven't ordered this yet... and I really can't tell what you can do with this in a propeller only environment... interested to find out though...
