Correction and Extraction of the Encoder Grating Image Full-Barcode

Article Preview

Abstract:

To improve the pertinence and accuracy of grating image barcode detection, a method based on Hough transform and morphological operation about grating image full-barcode correction and extraction is proposed. The basic principles of Canny edge detection, Hough transform and morphological operation are introduced. Non full-barcode can be eliminated after Canny detection and morphological operation. The level correction can be finished by using Hough transform to detect the full-barcode edge lines and get the correction angle. The full-barcode extraction can be achieved after the dilation of correction grating image and the reduction of free defects. The experimental results show that not only the non full-barcodes and free defects can be better filtered, but also we can accurately accomplish the correction and extraction of the full-barcodes.
