Abstract

Reconstruction of depth information is a common task in industrial inspections as measurement of mechanical components or for surface inspection. This paper presents a new approach for a real-time self calibrating stereo based system. The concept is based on calculating the difference-map of registered stereo images that contains qualitative depth information. The principle is valid for a variety of applications; a prototype for a 3D code reader is presented in detail. Experimental results from a laboratory prototype demonstrate the full functionality of the system concept.
