Learn about the Kailing OCR intelligent data extraction platform extension module: image capture processing and invoice recognition features

In today's digital era, image capture and processing and invoice recognition technologies play an important role in enterprise document management and financial processes. This article will introduce in detail Kailing TechnologyOCR intelligent data extraction platform Relevant functions and advantages of the two extension modules.

I. Image collection and processing

The image collection and processing workflow includes steps such as uploading images, image preprocessing, OCR, content analysis, naming and archiving, aiming to improve image quality and the accuracy of subsequent processing.

In terms of image capture, we have a browser-based document scanning SDK designed specifically for web applications, with a simple and easy-to-use API. With just a few lines of JavaScript code, powerful applications can be developed to scan all common documents into a web browser. This SDK supports TWAIN-compliant scanners and document cameras, including multiple models of scanners and document cameras, and is self-developed, controllable, and easy to integrate. At the same time, it supports domestic scanners and document cameras with high compatibility. The operating system is Windows 7 and above, and browser compatibility includes IE9 and above, Chrome, Firefox, Edge, 360, and others.

Image processing functions include cutting and correction, edge trimming, text correction, and purification and HD. Cutting and correction can automatically detect edges and cut single or multiple files/documents in an image, return the corresponding coordinate information and image base64 content, and provide rotation angles and support image correction and straightening. Edge trimming and text correction help optimize the image layout and text readability. Purification and HD can purify, smooth, sharpen, and denoise images, effectively removing interfering information, and can be used for digitization of historical archives to facilitate subsequent structured recognition processing and information extraction.

II. Invoice recognition

Invoice recognition covers a wide range of scenarios, including national tax document scenario recognition and financial write-off scenario recognition. National tax document scenario recognition covers multiple invoice types, such as general machine-printed invoices, general fixed-amount invoices, highway passenger transport invoices, shipping passenger tickets, taxi invoices, parking fee invoices, toll and bridge fee invoices, itineraries, train tickets, overseas invoices, etc. In financial write-off scenario recognition, intelligent document recognition technology supports automatic classification of dozens of common documents including national tax invoice types, local invoice types, and other invoice types, and can accurately recognize all fields such as document details and official seals, facilitating tax deduction, compliance inspection, and other scenarios, with recognition accuracy up to 95%.

Powerful full-category invoice recognition. For VAT invoices, it recognizes all invoice face information, provides line-item recognition, supports recognition of supervisory seals and financial seals, and also provides flags such as refined oil, agent-issued, blockchain, and toll, as well as invoice consumption type fields, providing a basis for accurate secondary classification and reimbursement compliance judgment. For travel invoices such as train tickets, bus tickets, and flight itineraries, it extracts passenger name and ID number fields to facilitate input VAT deduction. Toll invoices provide a field indicating whether the road is an expressway, as a reference for deduction. In addition, invoice special seal recognition is supported.

Significant product advantages and complete recognition fields, including recognition of relevant fields for VAT invoices, travel invoices, toll invoices, etc. At the same time, it supports mixed cutting of multiple invoices. The patented cutting model supports recognition of more than ten mixed pasted invoices. The system automatically cuts and classifies them and then recognizes and returns them one by one. It is suitable for a variety of common financial and reimbursement scenarios, reduces manual classification costs, greatly improves invoice recognition efficiency, and meets the needs of multi-image capture and pasted invoice recognition, with an automatic cutting and classification accuracy rate of over 99%.

In terms of technical advantages, intelligent document recognition can spatially layer machine-printed and printed content and then re-correct it, improving compatibility with content misalignment.

At the same time, content slices with red seals are directly added to training, enabling the engine to more accurately recognize character content covered by seals.

The comprehensive accuracy of fields for intelligent invoice recognition is above 95%, and the accuracy of key fields such as amount, invoice number, invoice code, and date reaches above 99%. For travel receipts, recognition of taxi tickets and passenger transport tickets nationwide is better, and the accuracy for air transport electronic ticket itineraries is above 92%, far higher than other products by 10-15%. In addition, accuracy is improved through multiple methods such as image optimization technology before recognition, high fault tolerance during recognition, and multiple alternative options after recognition. At the same time, the product has low variable costs; any image format extracted by any image extraction device is supported for recognition, with no need to replace or purchase front-end extraction devices.

The product also has the advantages of supporting recognition of images in multiple formats and generalized invoice recognition, with strong scalability, automatically classifying and recognizing various types of bills involved in scenarios such as business-finance-tax reimbursement and tax accounting. On the basis of supporting 21 categories of national tax invoices, it horizontally expands existing recognition scenarios, incorporating structured recognition of national fiscal electronic bills such as customs special payment statements, medical outpatient fee bills, central non-tax revenue unified bills, and social organization membership fee receipts into the existing recognition system.
