It's not exactly machine vision yet, but a researcher at Georgia Tech, Grant Schindler, has created what appears to be the first 3-D scanner app for an iPhone 4.
Using both the screen and the front-facing camera, the app--called Trimensional--detects patterns of light reflected off a face to build a true 3-D model.
Schindler says Trimensional can now share movies and animated GIFs of your 3-D scans and users can unlock the 3-D Model Export feature to create physical copies of any scanned object on a 3-D printer, or import textured 3-D scans into popular 3-D graphics software.
I wonder if and when such iPhone apps can be used in machine vision applications?
