The Institute of Laser and System Technologies (iLAS) of the Hamburg University of Technology (TUHH) investigated an intelligent vision guided laser remote scanner (LRS) system not only for thin sheet or structure applications, but also for thick sheet welding tasks with brilliant high power lasers up to 30 kw optical laser power. Two different wavelength(More)
This paper presents a two-step vision-based approach for real time inspection of the assembled valve keys in automobile cylinder heads. In the first step a combination of Sobel edge detector with gradient pair vector method is used for the detection of circular shaped valve keys. This method is very fast but also highly sensitive to noise, resulting in a(More)
