Plate surface code spraying character recognition device and method thereof

Abstract

The invention relates to a plate surface code spraying character recognition device and a method thereof, belonging to the technical field of character recognition. The plate surface code spraying character recognition device comprises a detector, a controller, a CCD (Charge Coupled Device) camera, an image acquisition unit, an image recognition processing terminal, a local data base, a sound-light alarm, a recognition result display, a human-computer interaction system and an upper-layer MES (Manufacturing Execution System) warehouse system, wherein the detector is connected with the controller to form a bottom-layer detection system; the controller is connected with the CCD camera, and the CCD camera is connected with the image acquisition unit to form an image snapshot system; the image acquisition unit is connected with the image recognition processing terminal, and the image recognition processing terminal is connected with the local data base, the sound-light alarm, the recognition result display and the human-computer interaction system respectively so as to form a character recognition processing system; and the image recognition processing terminal is connected with the upper-layer MES warehouse system via the Ethernet, and the upper-layer MES warehouse system is connected with the local data base via a network to form a character information interaction platform. The plate surface code spraying character recognition device has the advantage of realizing the fast and accurate recognition of plates during the roller bed transportation process.

Description

technical field [0001] The invention belongs to the technical field of character recognition, and in particular provides a device and method for recognizing coded characters on the surface of plates, which are suitable for automatic recognition of coded characters on the surface of metallurgical finished products. technical background [0002] During the production of steel products, the manufacturer will code each piece of product and stick the code on the surface of the product with various media. This process is called "marking", and the code attached to the product is also called "marking". In the production process of the board, the mark is the only identification for the whole process of tracking, management and quality traceability of the board from production to finished product on the market. At present, most domestic iron and steel plants generally use mechanical inkjet equipment for plate products to spray character marking information on the upper surface of the ...
