Problems solved by technology

However, the barcode on some materials will cause reflections due to the supplementary light source. In actual use, this method may encounter the user aiming at the barcode but due to the reflection, the scanned image cannot be successfully decoded.

Abstract

The invention provides a bar code processing method and a bar code scanning device. The method comprises the steps of: obtaining a first bar code image; judging whether a reflection area in a first bar code area exceeds a predetermined size range; if yes, obtaining N second bar code images, and judging the change trend of reflection areas according to the reflection areas in the first bar code image and the N second bar code; if the reflection areas increase gradually, obtaining a current bar code image; and according to the relative relation between the reflection area in the current bar code image and a third bar code area, adjusting an aiming light source module until the reflection area in the third bar code area of a current bar code image newly obtained after the adjustment of the aiming light source module is within the predetermined size range, using the current bar code image whose reflection area is within the predetermined size range as a decoding image, and carrying out processing so as to obtain data.

Description

technical field [0001] The invention relates to the field of barcode scanning, in particular to a barcode processing method and a barcode scanning device. Background technique [0002] Barcode or barcode (barcode) is a graphic recognition unit that arranges multiple black bars (bar) and white bars (space) of different widths according to certain coding rules to express a set of information. A common barcode is a parallel line pattern of black and white bars with very different reflectivity. Bar codes can mark the country of origin, manufacturer, product name, production date, book classification number, letter start and end location, category, date and other information, so they are widely used in commodity circulation, book management, postal management, banking systems and other fields. According to different application fields, the encoding format of barcode has various specifications. For example, one-dimensional barcode includes Code39, Code11, Code128, EAN (European A...
