Abstract

The invention provides a bar code recognition method and device. Information identification is carried out on the bar code; if the result information corresponding to the bar code is not successfullyacquired, the bar code is deleted; the method can be based on the image recognition result of the bar code. According to the method, the character area corresponding to the bar code is determined according to the identification result of the bar code, and the character information contained in the character area is extracted, so that the result information corresponding to the bar code is obtainedthrough the character information, the problem that the required result information cannot be directly obtained through the bar code under the condition that the bar code is partially damaged or cannot be identified is solved, and the bar code identification reliability is improved.

Description

technical field [0001] This application mainly relates to the technical field of image processing, and more specifically relates to a barcode recognition method and device. Background technique [0002] When the barcode is stained or printed unclearly, it will cause some bar spaces in the barcode to be indistinguishable, which will lead to the failure of barcode recognition and reduce the reliability of barcode recognition. Contents of the invention [0003] The application provides a barcode identification method, the method comprising: [0004] Carry out information identification on the barcode, and the information identification is used to obtain the result information corresponding to the barcode; [0005] If the information recognition of the barcode fails, based on the image recognition result of the barcode, determine the character area corresponding to the barcode; [0006] extracting character information from the character area; [0007] The result informatio...
