More Information
Summary:The invention discloses a method for recognizing punctiform characters on the surfaces of cables and belongs to the image processing field, in particular, belongs to the automated optical character recognition field. The method mainly comprises the steps of Otsu method threshold extraction and binarization, image preprocessing, cable regional coarse extraction, cable tilt correction, character segmentation, character tilt correction, template matching and identification logic design. The processing method of the punctiform characters on the surfaces of cables is put forward for the first time. With the method adopted, punctiform digits, English characters and few symbols on the surfaces of various kinds of cables can be accurately recognized. In a cable production process, character tilt appears in character jet printing inevitably, while, with the method of the invention adopted, accurate reorganization can be still performed when characters tilt slightly, and therefore, the method has a certain anti-interference ability.
