OCR-based code scanning payment cash register software amount recognition system

Abstract

The invention relates to an amount recognition system for code scanning payment cash register of merchants, and an implementation method of the amount recognition system. The amount recognition system is characterized in that: original cash register software of merchants does not need to be modified, and code scanning payment cash register software is additionally installed to achieve support for code scanning payment; when the code scanning payment cash register software is installed for the first time, a screenshot region in the cash register software is set by using a button (1) marked with ''selecting amount appearing region'', the code scanning payment cash register software automatically performs screenshot on a settlement amount region of the cash register software according to a preset range when carrying out code scanning payment settlement each time, an opencv computer vision library is used for performing preprocessing on a picture to generate a binary image and save it, then a specific amount is recognized and amount input is automatically achieved through OCR (optical character recognition) according to a language package which is specially trained and corrected.

Description

technical field [0001] The present invention relates to an amount recognition system for cash register software for scanning code payment for merchants, and its implementation method, in particular, the code scanning payment software automatically takes screenshots according to presets and performs OCR (Optical Character Recognition, Optical Character Recognition) to identify and automatically input the transaction amount . It belongs to the field of financial payment. Background technique [0002] With the continuous evolution of payment methods, the gradual expansion of payment channels, and the continuous promotion of new payment methods, scanning code payment came into being. Scanning code payment transactions refers to generating a payment wallet account security index information on the mobile phone, such as payment index information of Alipay and WeChat. This payment index information can be a one-dimensional code or a two-dimensional code, and then through the cas...

AI Technical Summary

Problems solved by technology

The cash register system manufacturers used in the first method require the cooperation of merchants while spending a lot of manpower, material resources, and financial resources on upgrading and transformation.

This method is very easy to destroy the information, data, settings and other content accumulated in the original cash register system, and may also cause system compatibility problems

The second solution is easier to implement on the cash register system, but it increases the operating requirements of the cashier staff. When there are many payers, the cashier is easy to enter the wrong amount, which makes the software less user-friendly.
