Abstract
The present invention relates to a method and system for reliable 3D shape extraction of a metal surface. In this method, images are acquired at the same time by simultaneously irradiating interference-free polarized lights to a metal object. A photometric stereo method is then applied based on the images except for images which make the extraction of a 3D shape of the metal object inaccurate.
