Abstract

Embodiments of the present invention provide a barcode identification method, device, and system. The scheme is as follows: acquiring a plurality of acquired images; locating at least one barcode included in the acquired image to obtain a positioning result of each barcode; based on the positioning result, intercepting each barcode in parallel from the acquired image to obtain an initial barcode image; The initial barcode image of each barcode in the acquired image is calculated in parallel to obtain the width of each barcode unit; based on the preset minimum width and the width of each barcode unit in the initial barcode image, the width of each barcode in the acquired image is calculated. The initial barcode image is subjected to width scaling processing in parallel to obtain the target barcode image; the target barcode image is decoded in parallel to obtain the information carried by each barcode in the captured image. By adopting the technical solutions provided by the embodiments of the present invention, the efficiency of barcode identification is improved, and the difficulty of barcode identification is reduced.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a barcode identification 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 identification of the barcode by the fixed equipment depends on the barcode image collected by the fixed equipment. Specifically, the fixed equipment identifies the barcode contained in the barcode image, and obtains the information carried by the barcode. However, in practical applications, the barcodes of objects with different heights have different distances from the ...
