Curtis,
Thanks for the response.
I have been thinking about this approach since I started the project. I used
OpenCV for the original model, comparing screen captures to one another. I
was, however, rather sceptical about how much I could use OpenCV. I'm not much
of a pilot but even I have trouble seeing the runway from the cockpit view.
Subtracting the non-runway-colors approach might not work... That said, it
might be the easiest approach, avoiding having to access any of scenery, scene
graph, etc. I think if I give the AI pilot a sense of where it is, how far it's
travelled, etc, I might be able to use that information to see the runway
again, or at least eliminate run-way like candidates. I also came across Marcos
Nieto's work on real-time lane detection. I wonder if I can use something
similar to tell the pilot when the plane is more/less centred.
Thanks again,
Sterling

Hi Sterling,
I have used ffmpeg to feed a video capture stream of flightgear into a fifo
pipe that can be read by an opencv application in real time. I did a little
write up on the flightgear.org web site:
http://www.flightgear.org/tours/developing-computer-vision-algorithms-with-flightgear/
The part where I talk about specific ffmpeg commands is down towards the end of
the article. I don't know if this method would be appropriate for you, but
it's something that was useful for my project.
Curt.

Suppose I wanted to write a program that can "see" outside, where would people

I am working on a psychology model of plane pilots. My first model was a simple
model of performing a take-off in the Cessna. To do this, I simply connected
the property tree to my psychology simulation software, and voila. Added a
quick and dirty motion detection (using screen shots) to "see" movement (to
deal with left turning syndrome during take-off). What I'd like to be able to
do next is to see the runway, and any visible buildings in the current view. I
had originally thought I'd one day make use of openscenegraph to do this...
Any thoughts?
Thanks,
Sterling
