Abstract
We present an active triangulation based system for 3D reconstruction of objects with large depth variations which are placed on a rotary table to obtain the entire 3D view. We project Fresnel diffraction from an edge to generate an illumination pattern with large depth of focus on the object surface. The frontier line separating dark from bright areas of the diffraction pattern is used for line sectioning of the object, and the height profile is obtained through triangulation. Three dimensional reconstructions are illustrated for various objects having 10 cm maximum depth variations: the depth measurement accuracy is 0.36 mm for an object average distance of 350 mm.
