Yup :)
I thought of, *after dealing with the mono vision*, going for a stereo
approach, because this is one way of dealing with distance measuring, or at
least, better object evaluation/recognition.
At first I thought of using two USB cams, but then, after thinking about
the technical problems dealing with two video sources, I thought of that
solution exactly. Using a kind of technic common to professional binocullars:
Left Right
: :
\:..\**/..:/
*\ :\/: /* 4 Mirrors
: :
|: :|
Camera
Well... in theory this works, but, in practice, I was expecting
difficulties when setting the angles of the mirrors correctly.
If more motor outputs were available, one could control the outside
mirrors, to deflect or inflect (just like we do with the eyes)
With angle-sensors attached, one could even do a crude distance measuring,
when trying to focus an individual object/point of reference.
Anyway, without the pair of motor/angle-sensor attached, it's still
possible to do crude distance measuring with the fixed angle.
Like this, we get better edge/object recognition
Oh well... when I have the time... but, anyway :) Laurentino, keep us up to
date with your project :)
