Paper Abstract

An adaptive stereoscopic vision system has been examined for the task of industrial inspection. With fixed optical setups and working under large defocusing the camera system is simple and robust in construction and reliable in working accuracy. Applied in combination with an adaptive control of the industrial robot industrial parts with various forms and sizes can be inspected under demanded accuracy. As a basis the characteristics of the camera system have been investigated by different optical setups and measuring distances. The calibrations show a good conformance of the camera with its mathematical model under a measuring distance from 325 to 825 mm. The achievable accuracy of the stereoscopic vision system under different camera arrangements is better than 0.5% through a measuring distance of 353 to 1278 mm.
