Heheh...what a coincidence. I started making a 3d scanner not too long ago
for use in pov.
It's nearly complete, although I've decided to move the laser beam with the
camera along a linear path rather than sweeping it as in the link (that's
where I'm at now, building the positioner assembly). The first method I
used was to rotate the object on a turntable to make a cylindrical height
field, but now I want to scan the faces of large objects so I can get
accurate models (such as a head from an automobile engine) into Solidworks.
Still having HUGE problems with the Canon camera SDK. It's so unstable. I
think I'll have to limit the camera type to Logitech webcams. Too bad too.
Could have been many megapixels per image taken for each laser line, but,
looks like it will be 640x480 if I can't get it working. Resulting height
field will have much less resolution/accuracy :(.
