3D SCANNERS

Finally, consumer-grade scanners for your desktop!

WRITTEN BY NICK PARKS

3D scanning at home was nearly impossible without expensive pro equipment or DIY setups, until now. Consumer-grade scanners have arrived, based on two main depth-sensing technologies. Triangulating laser scanners project a laser line on the object, record it with a camera, and compute the triangulated position of the surface. Structured-light scanners project a pattern onto the object and calculate depth by measuring distortions in the pattern. We tested one of each to see how they work.
