Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that when the item with the barcode to be decoded moves too fast and the decoding time is too long, the current decoding method while scanning while decoding is likely to miss a shot or solution due to insufficient decoding time or due to movement. The speed is too fast, which leads to the poor quality of the captured barcode image and affects the accuracy of decoding. A method of reading and decoding barcodes using the enhanced code reading mode is proposed.

Embodiment Construction

[0023] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0024] Please refer to figure 1 , the present invention provides a method for reading and decoding barcodes using enhanced code reading mode, comprising the following steps:

[0025] S1: Complete the decoding preparation work, the decoding device is facing the delivery track of the items with barcodes, and the number of barcodes on each item is at least 1.

[0026] S2: Start the decoding device. When the items with barcodes pass through the decoding device, trigger the decoding device to continuously capture and cache N barcode images, N≥2.

[0027] S3: output the N images to the decoding library.

[0028] S4: The decoding library sequentially decodes all the barcodes on the N images until all the barcodes on the images are decoded.

[0029] S5: Output the decoded ...

Abstract

The invention provides a method for reading and decoding a bar code by applying an enhanced code reading mode, which comprises the following steps of: shooting a plurality of image bar codes when thebar code quickly passes through decoding equipment, and decoding the shot image bar codes one by one within a longer time interval before the next article pasted with the bar code to be decoded arrives; and until all the bar codes in the image are decoded, outputting the decoded data. According to the invention, a plurality of shot bar code images are decoded in sequence by utilizing the long moving time of the interval distance between two articles pasted with bar codes to be decoded, so that the plurality of bar code images comprise a clear and complete bar code image, the decoding time is sufficient, the decoding accuracy is high, and the situation of missing decoding can be effectively prevented.

Description

technical field [0001] The invention relates to a decoding method of an image barcode, in particular to a method for reading and decoding an image barcode by using an enhanced code reading mode. Background technique [0002] Bar code technology is an automatic identification technology produced and developed in the application practice of computers. It is designed to realize automatic scanning of information, and it is an effective means to realize fast, accurate and reliable data collection. The application of barcode technology solves the bottleneck problem of data entry and data acquisition, and provides favorable technical support for logistics management. A barcode is a symbol composed of a group of regular bars and corresponding characters, which is used to represent certain information. The core content of barcode technology is to use photoelectric scanning equipment to read these barcode symbols to realize the automatic identification of the machine, and quickly an...
