Re: Camera software

I'm considering prototyping one using a couple of webcams mounted on
my Sherline, assuming my math is right and it'll be worth the time.
It'll probably be a sloppy mess like you find in a research lab
though.

I'll stick with stereo cameras because depth map software works better
if the light source is fixed relative to the object that's moving. In
fact, it's better for the camera to move around the object unless
you're using structured light illumination (I think one of the
in-development system uses slit illuminator.)

Stereo software works by triangulating features in the image from two
views, so there isn't need to project anything on the image except to
enhance surface texture, in which case you could use anything, really.
Wideband white noise that changes every frame would be best, but I
haven't found a cheap way to do that.

Right now I'm looking at two CMOS cameras with around 3Mpixels and an
LED light source. And software. That plus a way to calibrate the whole
system, like a set of gauge blocks.
