38 Thin Steel Plates Counting Method Based on Digital Image Processing

The method involves counting thin steel plates for car chassis in stacks by using digital image processing and a software interface. First enhance the photo of the stacked plates to a clear intensity image. After manually selecting the region of interest by the user and detecting the lines of each plate, adjust the lines to the vertical direction by horizontally shearing the image against the inclination angle. Finally, count the number of plates in the picture by counting the intensity pitch. The approach is efficient and accurate in counting plates. It relies on two-dimensional processing and requires no mechanical equipment as the traditional means.
