Method for automatic identifying steel slab coding and steel slab tracking system

Abstract

The invention discloses a method for automatic identifying steel slab coding and a steel slab tracking system. The method is characterized in that: from the starting of a first frame original image, automatic identification of slab coding is successively carried out on each frame of original image by the following steps: step 1, carrying out image preprocessing on the original image; step 2, carrying out binarization processing on the image after the preprocessing and carrying out slab coding detection and coding position positioning on an obtained binary image, wherein the slab coding detection and coding position positioning employ a projection processing method; and step 3, splitting the original image according to a boundary coordinate that is obtained by the coding position positioning to obtain a plurality of single character images and carrying out character identification on the each single character image, thereby completing slab coding identification on the original image of the current frame; and then returning to the step 1. According to the invention, the method for automatic identifying steel slab coding and the steel slab tracking system have characteristics of high automation degree and high coding identification efficiency.

Description

technical field [0001] The invention relates to an automatic identification method for codes of iron and steel slabs and a tracking system for iron and steel slabs. Background technique [0002] With the development of industrial automation, in the iron and steel industry, enterprises have gradually increased the requirements for the automation level of logistics management. Steel slab information, that is, steel slab code, is important information for the logistics management and production process of iron and steel enterprises, usually using certain letters Or numbers and their combined codes indicate that automatic acquisition of steel slab information is of great significance for steel slab tracking in logistics management and enterprise automation and information production. Steel slab tracking means that the slab management information screen in the material module of the steelmaking side in the MES system automatically receives the slab cutting information and weighin...

AI Technical Summary

Problems solved by technology

This semi-automatic steel slab tracking system cannot accurately and real-time track the condition of the slab sent from the converter plant to the hot rolling mill. The MES system does not perform real-time corrections for the information changes generated during the transfer process, making the information in the MES system consistent with the There are differences in the actual steel slab information, and the consistency between physical objects and information in the front and rear processes cannot be truly realized, and the automatic tracking of steel slabs in the first-level system has not been truly realized
