METHOD AND SYSTEM FOR RELIABLE 3D SHAPE EXTRACTION OF METAL SURFACE

摘要

The present invention relates to a method and system for 3D shape extraction of a metal surface which is capable of reliably extracting a 3D shape of a metal object surface by applying images, which do not have direct reflected light, except for images which make the extraction of a 3D shape of a metal object inaccurate by irradiating interference-free polarized lights to the metal object at the same time, to a photometric stereo method.
