Online Quality Inspection of Cutting Knives in a Wood Chipper.

      Аннотация: Machine Vision (MV) is a broad field that is growing very rapidly and being used in every automation control system. Machine Vision is the analysis of images/pictures to extract data of interest for controlling a process or activity. This work focused on measuring the quality of the cutting knives that are moving with the speed of 45 m/s in a real time wood chipper. On the basis of that quality measurement it is decided that knives in a wood chipper should be replaced or not. While measuring the quality of knives the effect of blurring effect due to very fast motion of knives is also investigated for different exposure times. Different types of illumination sources are discussed and described that which illumination source is suitable for this type of challenging environment and application.
