Title:Steel Coil, Straps and Packaging Recognition under Natural IlluminationAuthor(s):Patrick Hölzl, Daniel Schleicher, Bernhard ZagarAbstract:Due to the ever increasing quality levels in the steel industry quality control via machine vision systems gets ever more important. In this paper a robust algorithm to detect the coils outline, straps and packaging under natural illumination is presented. In contrast to machine vision applications operating under well defined lighting conditions, in steel industry such illumination can not be applied without enormous costs. Coping with these adverse lighting conditions dramatically increases the algorithmic burden on the image processing task. We show that generating and using high dynamic range images and a priori knowledge about the scene, enables a satisfying object recognition protocol.Booktitle:IASTED International Conf. on Visualisation, Imaing and Image Processing (VIIP 2009)Page Reference:8 page(s)Publishing:2009
