The invention relates to a bar code identification method based on machine vision. The method comprises steps that a bar code characteristic vector of acquired known coding rules is trained by employing a nerve network, bar code characteristics are analyzed, a bar code database is established, the nerve network having identification capability and capable of realizing stable training is acquired, whether a to-be-identified bar code belongs to bar code types in a sample database is determined through analyzing a to-be-identified bar code characteristic vector in a bar code identification process, if yes, a corresponding decoding program in a decoding database is called for decoding, the bar code is identified, if not, the bar code characteristic vector is added to the sample database according to demands, training is carried out by employing the nerve network, the corresponding decoding program is added to the decoding database, so the bar code in the type can be identified in the next identification progress. Through the method, the bar code database is more convenient to maintain, bar code identification types are enhanced, and thereby bar code identification type scalability and identification efficiency are improved.
Description
technical field [0001] The invention relates to the technical field of barcode identification, in particular to a machine vision-based barcode identification method. Background technique [0002] In recent years, with the continuous popularization of computer applications, the application of bar codes has been greatly developed. Bar codes can mark the country of production, manufacturer, product name, production date, book classification number, mail start and end locations, categories, and dates. Barcode recognition technology is an important method and means for automatic identification and input of information data, and has been applied to all walks of life in the national economy such as commerce, industry, transportation, post and telecommunications, logistics, medical and health. At present, there are more than 225 kinds of barcodes in the world, and each barcode has its own coding rules, which can meet the requirements of logistics tracking, status recording, warehous...
