Interesting Paper on Inexpensive Laser Scanning

Here’s a pointer to a cool technique for scanning 3D objects. It’s cool in that it uses very simple equipment: a cheap webcam, a corner bracket (just a backing plate that forms a 90 degree angle and has a calibration target on it) and a handheld laser modified to cast a line.

I’ll look at it more later.
