A system and method for intelligently identifying on-line mobile slab mark

Abstract

A system and method for intelligently identifying on-line moving slab mark are disclosed. The system comprises a billet conveying roller table; An image acquisition camera is arranged beside the billet conveying roller table, the data line of the image acquisition camera is connected to an image processing control server, An image acquisition camera processes an original image captured containinga sprayed white string, to find the character characteristics of each character in the string, compares the found character features with the character identification features in the character identification features database to find out the corresponding characters, The string number formed by the corresponding characters is recorded in the slab database and simultaneously sent to the client to display the string number on the interface of the client, and then the string number is sent to the production system for subsequent production links. The present invention solves the problems of highlabor intensity, easy error, high processing speed and no error before manual removal of slab.

Description

technical field [0001] The invention relates to an online mobile slab identification intelligent identification system and method, which is an application of intelligent identification of slab numbers in the slab production process of steel mills. Background technique [0002] At present, in the steel production process, it is necessary to accurately track the finished and semi-finished products in the production process, so the unique codes for tracking are sprayed on the surface of the products, and these codes are mainly composed of letters and numbers. Usually, when these codes are used in subsequent processes, it is necessary to manually go to the slab to transcribe and identify them, and then manually transfer these codes to the next process or enter the system. This approach mainly has the following disadvantages: [0003] 1) The site of the slab belongs to the high-temperature area. Usually, the temperature of the slab that has just been rolled has a temperature of ...

Problems solved by technology

[0008] The purpose of the present invention is to propose an intelligent identification system and method for moving slab marks on the line. A camera and a laser positioning device are set up next to the roller table of the slab production line. Take pictures, and at the same time, the pictures collected by the camera will be transmitted to the recognition server, which will automatically trigger the slab recognition system program, intelligently recognize the number of the slab from the collected images, and solve the problem of irregular spraying characters by establishing a learning character library. There is a problem of misidentification
