Adaptive color classification for structured light systems

Abstract

We present a system to capture high accuracy 3D models of faces by taking just one photo without the need of specialized hardware, just a consumer grade digital camera and beamer. The proposed 3D face scanner utilizes structured light techniques: A colored pattern is projected into the face of interest while a photo is taken. Then, the 3D geometry is calculated based on the distortions of the pattern detected in the face. This is performed by triangulating the pattern found in the captured image with the projected one.
