The depth from focus measurement principle relies on the detection of the optimal focusing distance for measuring the depth map of an object and finding its 3D shape. The principle is most effective at microscopic ranges where it is usually found implemented around a z-controlled microscope and sometimes named multifocus 3D microscopy. Assuch, the method competes with many other 3D measurement...

Configuration assistant for versatile vision based inspection systems

Hüsser, Olivier ; Hügli, Heinz

In: Machine Vision Applications in Industrial Inspection VIII (Proceedings of SPIE), 2000, vol. 3966, p. 259-269

Nowadays, vision-based inspection systems are present in many stages of the industrial manufacturing process. Their versatility, which permits to accommodate a broad range of inspection requirements, is however limited by the time consuming system setup performed at each production change. This work aims at providing a configuration assistant that helps to speed up this system setup, considering...
