Research and Implementation of Value Added Tax Invoice Parsing and Recognition System
Value added tax invoices are the most commonly used payment vouchers in various economic transactions,and manual processing of invoices during financial reporting is inefficient.Based on this,the paper designs and implements a value added tax invoice parsing and recognition system.The system classifies different types of invoice documents.Electronic invoices in text type are directly parsed using XML document processing tools,while scanned copies of paper invoices are recognized using PaddleOCR.Before identifying scanned copies of paper invoices,first parse the QR code to obtain the location information and text content of the QR code.Based on location information,the invoice image is directional corrected,and the corrected image is sent to the OCR recognition module for text recognition.The content obtained through QR code parsing is used to verify the OCR recognition results,thereby improving the reliability of the recognition results.
