Embodiment Construction

[0031] In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0032] refer to figure 1 A method for reading barcodes with high pixel images, comprising the following steps:

[0033] S1: start;

[0034]S2: Capture and store image data; the image data contains at least one barcode symbol; in one embodiment, the arrangement of the at least one barcode symbol is matrix or linear, and the barcode symbol can also be Arbitrary irregular arrangements are adopted, and various arrangements will not affect the subsequent extraction and decoding of barcode symbols. Image data can be captured by equipment with a camera module such as scanning and picture capture, and any image capture device can be used to capture images continuously or discontinuously. The continuous is also called continuous scanning mode...

Abstract

The invention relates to a barcode reading method and device of a high-pixel image. The method includes the following steps that: S1, the method is started; S2, image data are captured and stored, wherein the image data contain at least one barcode symbol; S3, the image data are processed, and the barcode symbols in the image data are extracted, and are stored; S4, the extracted barcode symbols are decoded, after the decoding of each barcode symbol is completed, the barcode symbols are destroyed, and decoding data obtained after the barcode symbols are decoded are stored, and whether the extracted barcode symbols contain decodable barcode symbols is detected, if the extracted barcode symbols contain decodable barcode symbols, the step S4 is cycled; and S5, the method is terminated. The barcode reading method and device of the high-pixel image of the invention can obtain high-pixel image data and automatically read barcode data information on the high-pixel image. With the barcode reading method and device of the high-pixel image adopted, a plurality of barcodes on the high-pixel image can be automatically identified, and barcode data can be obtained with one step.

Description

technical field [0001] The invention relates to the field of barcode image recognition and processing, in particular to a barcode reading method for high-pixel images and a barcode reading device for high-pixel images. Background technique [0002] With the development of science and technology, the application of barcode technology has gradually penetrated into our daily life and work. Two-dimensional codes can include coding schemes such as QR codes, DM codes, and Hanxin codes, which can encode information such as characters, text, and images. After error correction coding, the obtained two-dimensional code stream is represented as a two-dimensional code symbol, which is currently widely used in document reading, logistics and electronic data exchange. The main functions of barcode technology in the prior art include information acquisition, website jumping Transfer, anti-counterfeiting traceability, preferential promotions, member management and mobile payment, etc. [0...
