STANDARDS AND REFERENCE ARTEFACTS FOR OPTICAL INSPECTION SYSTEMS

Eugen Trapet

Abstract

The use of optical systems for the dimensional inspection in industrial production (e.g. automotive, aeronautic) is steadily increasing. However, a thorough performance verification of such systems must still become more popular; now international standards have been published and the habit of verification may improve. The presentation will introduce to the key elements of prevailing standards. The basic rules for performance verification of Video CMMs and CMMs with fringe projection sensors and laser scanners, stand alone fringe projection and scanner systems will be discussed. In order to facilitate the verification according to prevailing standards, the author has developed a series of reference objects. These will be presented. A thematic excursion to some reference objects developed for the verification of photogrammetric and tomography systems will be made. For each measurement system the inherent problems and the developed solutions for the corresponding test artefacts will be analyzed.
