Abstract

The embodiment of the invention provides a bar code identification method, device and system. The method comprises the following steps: acquiring a plurality of acquired images; positioning at least one bar code included in the acquired image to obtain a positioning result of each bar code; intercepting each bar code from the acquired image in parallel based on a positioning result to obtain an initial bar code image; calculating the initial bar code image of each bar code in the acquired image in parallel to obtain the width of each bar code unit; based on the preset minimum width and the width of each bar code unit in the initial bar code image, performing width scaling processing on the initial bar code image of each bar code in the acquired image in parallel to obtain a target bar codeimage; and decoding the target bar code image in parallel to obtain information carried by each bar code in the acquired image. By adopting the technical scheme provided by the embodiment of the invention, the bar code identification efficiency is improved, and the bar code identification difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a barcode recognition method, device and system. Background technique [0002] As an information carrier, barcodes are widely used in all aspects of production and life, such as the logistics industry. With the continuous development of information technology, barcode recognition has gradually changed from the traditional manual scanning code recognition method to the automatic scanning code recognition method of fixed equipment, which greatly liberates manpower and saves costs. [0003] The barcode recognition by fixed equipment depends on the barcode image collected by the fixed equipment, specifically: the fixed equipment recognizes the barcode contained in the barcode image to obtain the information carried by the barcode. However, in practical applications, objects with different heights have different distances between their barcodes and the fixed equipment, which...
