Embodiment 1

[0055] This embodiment provides a plug-in-based invoice recognition method, mainly using the QT plug-in mechanism to flexibly increase the recognition plug-in that can be used to identify the image information of the invoice; refer to figure 1 , the method includes:

[0056] S01. Import the pre-created recognition plug-in into the dynamic link library; wherein, the recognition plug-in is created based on a recognition algorithm adapted to the corresponding type of invoice;

[0057]The identification plug-in referred to in this embodiment is an application plug-in in QT. QT has a built-in plug-in mechanism, through which the software can support plug-ins set by users. Among them, QT has two APIs related to plug-ins. The first one is used to expand the QT library itself, which is called advanced API. The other is to expand the application program developed by the QT library. The two APIs are different, the latter is based on the former. In this embodiment, the low-level API ...

Embodiment 2

[0093] Based on the method provided in Embodiment 1, this embodiment also provides a plug-in-based invoice identification and management system. This system is mainly developed using the QT creator integrated development environment. When developing, a plug-in interface is configured. The plug-in interface The configuration process is an existing technology, and will not be repeated in this embodiment.

[0094] refer to Figure 6 , the system includes a database, an invoice input module, an invoice identification module, a user management module, an invoice management module, a backup module and a log management module.

[0095] Wherein, the plug-in interface is used to import the pre-created recognition plug-in into the dynamic link library; wherein, the recognition plug-in is created based on a recognition algorithm adapted to the corresponding type of invoice;

[0096] The invoice input module is used to obtain the image information of the invoice to be identified, and its...

Abstract

The invention discloses a plug-in-based invoice recognition method, and a recognition and management system; wherein, the recognition method includes: importing a pre-created recognition plug-in into a dynamic link library; wherein, the recognition plug-in is based on the corresponding type of invoice Create a recognition algorithm; obtain the image information of the invoice to be recognized and its type; call the corresponding recognition plug-in from the dynamic link library according to the type of the invoice to be recognized to identify the image information of the invoice to be recognized, and then Get the required invoice information. The advantages of the present invention are: 1. Employees can enter invoice information by themselves, and submit the invoice information to the background for processing by financial personnel, thereby reducing the burden on financial personnel; 2. Whenever a new type of invoice appears, it can be dynamically submitted to The recognition algorithm for this type of invoice is added to the system, so that the system can recognize new types of invoices, and solve various invoice recognition problems from an engineering perspective.

Description

technical field [0001] The invention relates to an image recognition technology, more specifically, it relates to a plug-in-based invoice recognition method, and a recognition and management system. Background technique [0002] In foreign countries, many companies have devoted themselves to the research of OCR, such as AcuForm in the United States, ABBYY in Russia, A2iA in France, etc., and their products are mainly used in accounting business and printing business. Russian company ABBYY has developed a professional OCR software ABBYY FineReader Professional. FineReader software not only supports the recognition of multiple languages, but also can recognize color documents, and there are many other powerful functions. A2iA Company has designed a check recognition software, which not only processes checks quickly but also has a high recognition rate [4]. With the in-depth research on the OCR system, its products are also used in many fields. [0003] There are many open s...
