Use a free download to turn a laser level and a netcam into a highly accurate 3D scanner... all you need is a corner and a printer to make it all work!

Watch and download here.

Yes, very very cool episode. I wish I had an excuse to get the necessary laser to do some 3D scanning with, but right now I can't think of any need or perceived need for the ability to 3D scan. Maybe one day in the future I'll have the "if only I had a 3D scanner..." situation and remember back to this episode

Very cool!

I might have to try this out.. although not trusting my hands I'd probably try the servo mounts or some other kind of steadying option.

I wonder if locking down both the camera AND the laser line, then reflecting the line with a mirror at a micro-fine speed would help? Less moving parts, at least. You can't lock the camera and laser together then scan down the object, because with this software you'd end up with a single line on camera that would warp all over as you moved across the object. Also, I guess you have to have the laser mounted so that as the line passes across a curved object, the line bends around the object. It seems that if you were scanning, say, a spray paint can from straight on, it would look like a flat rectangle. So you need sort of a perspective angle on the laser line. Or maybe just having the laser and the camera at a different height would fix that.

What about reflective objects? The Albino Tux was a good color for that duty, but would you need to keep a can of satin white spray paint handy for other things?

A million questions.... I gotta go find a laser level.

It was nice to see tux being a part of it.I noticed he was using a mac and the software to do the scan requires .net which is usually a ms product. Very interesting. Maybe a comment was made about that. I did not watch the episode in detail.......

The hardware was indeed Apple, but the OS wasnt.
