Two-dimensional code reading method and device based on Linux system

Abstract

The invention provides a two-dimensional code reading method based on a Linux system, and the method comprises the steps: carrying out the networking of mobile payment equipment which is distributed in a plurality of scenes and supports the cooperative application of configuration sensors, input equipment and a printing device, and enabling the mobile payment equipment, an electronic terminal based on the Linux system and a server cluster to be connected; obtaining parameter data to generate a two-dimensional code image; when it is monitored that the payment event is triggered, code scanning payment and non-contact card swiping payment are supported, and a first distance measurement sampling point is monitored, reading operation is completed in a deduction scanning mode. The method aims ata two-dimensional code image. Otsu algorithm coarse segmentation and secondary segmentation are adopted, feature extraction is carried out on a two-dimensional code image through a deep self-learningalgorithm, and for an electronic terminal based on a Linux system, code scanning payment and non-contact card swiping payment are efficiently and accurately recognized and paid in a network distribution environment where code scanning payment and non-contact card swiping payment are supported in multiple scenes with large environment parameter changes. The invention further provides a two-dimensional code reading device based on the Linux system.

Description

technical field [0001] The present disclosure relates to the field of mobile payment technology and the field of image recognition technology, in particular, to a method and device for reading two-dimensional codes based on a Linux system. Background technique [0002] In the prior art, cash register methods applied in multiple scenarios are POS machine card swiping, cash and other methods. Open the electronic terminal for the payer in very few scenarios, and provide static QR codes for multiple scenarios (the static payment image will inevitably contain some impurities, interference, etc. during the production and image collection process, Make the image have noise, fuzzy, uneven gray level) to scan, read the information of the QR code, and complete the payment operation. The above cash register method makes the form of cash register single, and because multiple scenarios are different due to the actual environment, for example, in the electronic terminal based on the Linu...

AI Technical Summary

Problems solved by technology

The above cash register method makes the form of cash register single, and because multiple scenarios are different due to the actual environment, for example, in the electronic terminal based on the Linux system, in the scene where multiple environmental parameters change greatly, the recognition of the two-dimensional code, Even the accuracy and speed of payment put forward higher requirements

Existing solutions do not have the accuracy, speed and ease of reading QR codes
