Problems solved by technology

[0003] Generally, barcodes are printed on paper media or displayed on the screen. For camera-based barcode reading devices, the camera takes dozens of pictures per second. However, most of the captured pictures do not meet the specifications. For example, barcode The display is incomplete or the photos are blurred, but the current barcode recognition program will also send these pictures to the reading engine for processing, and the barcode reading engine processing is the module that consumes the most CPU resources. A large number of pictures that do not meet the specifications waste CPU resources. , leading to a relatively low reading speed, and at the same time affecting the CPU to process other businesses

Embodiment Construction

[0020] In order to make the above objects, features and advantages of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The invention provides a method for realizing barcode reading. The method obtains qualified barcode photographed images by adding the preprocessing judgment function of pictures, so that the barcode photographed images read by the barcode recognition engine all meet the standard range, so as to achieve The purpose of saving CPU resources and improving the speed of barcode reading.

[0022] The implementation steps of this method can be found in figure 1 , including the steps of obtaining qualified barcodes and the steps of reading qualified barcodes:

[0023] S11. The step of obtaining a qualified barcode, specifically including:

[0024] S11.1 acquires the image captured by the barcode;

Abstract

The invention discloses a method and a device for realizing barcode recognition. The method comprises the following steps of: performing graphic processing on a shot barcode image, obtaining an envelope image, and judging whether the envelope image meets the barcode readable standard, only processing the shot barcode image of which the envelope image meets the barcode readable standard by using a barcode reading engine, and deleting the unqualified shot barcode image, so the number of the shot barcode images processed by the barcode reading engine is reduced greatly, the CPU (Central Processing Unit) resource is save, and the barcode reading speed is increased.

Description

technical field [0001] The invention relates to the field of barcodes, in particular to a method and device for realizing barcode reading. Background technique [0002] With the continuous acceleration of the mobile Internet process, barcodes are more and more widely used in electronic certificates, anti-counterfeiting traceability, print magazines and digital publishing and other fields. The resulting barcode recognition software and barcode reading equipment will also be developed rapidly. According to the reading method, barcode reading equipment is divided into laser head method and camera method. For the camera method, the barcode recognition software program reads the shot The photo of the barcode is sent to the reading engine, and the reading engine translates the barcode in the photo into useful information. [0003] Generally, barcodes are printed on paper media or displayed on the screen. For camera-based barcode reading devices, the camera takes dozens of picture...
