Stereoscopic vision - an application oriented overview

Machine vision and it's application in the manufacturing industry and other field has become one of the most exciting activities in computer vision. Many vision systems have been developed for the tasks of inspection, measurement and assembly. Some of them which are able to solve the problems with 1-D, 2-D or simple 3-D informations have already been applied in the production procedures. The vision systems, which are capable for the tasks where general and complicated 3-D problems are to be solved without loss of flexibility and efficiency, are drawing more and more attention from the field of development and application. This survey paper focuses on the main principles and techniques used by three dimensional vision systems for the inspection, measurement and assembly procedures in industry. They are organized into two groups: active-vision and passive-vision, according to the difference in the illumination procedures. To get a quick glance of them tables with figures and brief expla nations are presented
