PS: An ardrone vision program exists (BrightSpotDetector) that will stream the image coordinates of the brightest spot in the down-looking camera via TCP to a paparazzi module comes quite close to what you want for the landing?

Possibly so! I will try to find time to take a look, but...

 

This has been done before but is not very user friendly yet. Work is on the way to improve that.

The idea is:

git clone https://github.com/tudelft/ardrone2_vision ./paparazzi/sw/ext/ardrone2_vision

make (will also download submodule, and makes the gstreamer plugins with your custom code)

make drone (called from ardrone2_gstreamer folder: only needed 1 time: will put the framework on your drone)

put the libPlugin.so on the drone, and start gstreamer using command as in sourcecode

(if first make fails at the end) make install (will install scratchbox2 and qemu if you didn't have them)

(if make is still not working) gedit ./ardrone2_gstreamer/Makefile edit the path to your ardrone crosscompiler and make install again to setup sb2

OK, but then what?

Cool. I'll give it a try when I next get a chance.

I think I read somewhere that the ardrone2 has a DSP - have you looked
into using that yet?

Because I've been flying mine from my fields, I've had to use a
platform to launch it from (the grass is too long to do it from the
ground). As it happens, the platform I'm using is a bright yellow
stool. I was wondering if it would be possible to use the camera to
land on it :-) (Just idle speculation really).

On a related note, is it possible to record the video during a
paparazzi flight? And/or view it live?
