Example Embodiment

[0083] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be pointed out that for those of ordinary skill in the art, a number of modifications and improvements can be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0084] Such as figure 1 As shown, the entire printing character image recognition and verification system is composed of four parts: character generation, character printing, character recognition and character verification. The whole system can automatically realize the automatic recognition and automatic verification of the character marks on the product surface, without the need for human eyes to compare the recognized characters with the actual printed characters on the...

Abstract

The invention provides a character image jet-printing, recognition and calibration system and method. A character generation portion comprises a character body portion, a calibration code portion and a connecting portion. When the system distributes an identification character string for a product according to production characteristics of the product, the character generation portion can add a calibration code portion character string of the identification character string and a connecting portion character string of the identification character string behind a character body portion character string according to the identification character string, namely, the character body portion, thereby generating a character generation character string. A character jet printing portion is used for achieving jet printing of the character string on the surface of the product. A character recognition portion is used for recognizing the character string printed on the product in a jetting mode. In a character calibration portion, a calibration rule is adopted in a recognition result to as to calculate calibration codes, and whether the recognition result is correct or not is judged. The character image jet-printing, recognition and calibration system and method can effectively guarantee the code recognition accuracy.

Description

technical field [0001] The present invention relates to the recognition and verification technology of jet-printed characters, in particular to a jet-printed character image recognition and verification system and method, which can be widely applied to the accurate recognition of jet-printed characters on the surface of various types of materials. Background technique [0002] In the current iron and steel manufacturing and related fields, the life cycle tracking management of products usually uses one or two-dimensional code labels and reader equipment to complete the entry of product information. Usually, the two-dimensional code label will pre-store the product's manufacturing-related attribute information (these attribute information can uniquely identify the product) on the body of the code, and then install the label on the corresponding product that needs to be tracked. Since the storage information of the label can uniquely identify the product, when the label follow...
