Embodiment 1

[0031] An embodiment of the present invention provides a method for comparing paper documents and electronic documents, see figure 1 A flow chart of a comparison method between a paper document and an electronic document is shown, including the following steps:

[0032] Step S102, acquiring the first picture corresponding to the paper document.

[0033] Paper documents include paper documents derived from electronic documents, such as paper texts, contracts or clauses. The first picture is the electronic version of the document obtained after converting the paper document. To obtain the first picture corresponding to the paper document, you can obtain the first picture after judging that the clarity is qualified. For example, you can follow the steps below:

[0034] (1) Receive the picture file obtained by scanning the paper document by the picture acquisition device.

[0035] The paper document is scanned by the picture acquisition device, and the scanned document is used ...

Embodiment 2

[0065] Embodiment 2 of the present invention provides a method for comparing paper documents and electronic documents, see figure 2 A flow chart of another method for comparing paper documents and electronic documents is shown, including the following steps:

[0066] Step S202, reading the text file of the electronic file.

[0067] The electronic document text file refers to the original electronic document for comparison.

[0068] Step S204, converting into a PDF file.

[0069] The PDF file is obtained by converting the format of the text file of the electronic file into the PDF format.

[0070] Step S206, splicing multi-page files.

[0071] Stitch each page of the PDF file together sequentially.

[0072] Step S208, forming an original image file.

[0073] The original picture file refers to the file formed by splicing PDF files.

[0074] In step S210, the scanner scans the paper version of the document.

[0075] Paper documents refer to paper documents used for compa...

Embodiment 3

[0092] Embodiment 3 of the present invention provides a device for comparing paper documents and electronic documents, see image 3 A schematic structural diagram of a device for comparing paper documents and electronic documents is shown, including a first picture acquisition module 31, a second picture acquisition module 32, an algorithm module 33, and an output module 34. The functions of the above-mentioned modules are as follows:

[0093] The first picture acquisition module 31 is used to acquire the first picture corresponding to the paper document, and the first picture is obtained by scanning the paper document by the picture acquisition device;

[0094] The second image acquisition module 32 is used to perform image conversion on the electronic document to obtain the second image;

[0095] The algorithm module 33 is used to compare the first picture and the second picture by a preset comparison algorithm to obtain a comparison result;

[0096] An output module 34, co...

Abstract

The invention provides a contrast method, device and system of paper document and electronic document, and relates to the technical field of the document contrast. The method comprises the following steps: acquiring a first picture corresponding to the paper document, wherein the first picture is acquired by scanning the paper document by a picture collection device; performing picture conversionon the electronic document to obtain a second picture; contrasting the first picture and the second picture through a preset contrast algorithm to acquire a contrast result; and outputting the contrast result. The first picture acquired by scanning the paper document and the second obtained through electronic document conversion and splicing are contrasted by using a preset contrast algorithm, andthe contrast result is output, the contrast efficiency can be increased, the contrast time is reduced, and the error rate is lowered.

Description

technical field [0001] The present invention relates to the technical field of document comparison, in particular to a method, device and system for comparing paper documents and electronic documents. Background technique [0002] With the development of the economy, the pace of legal construction continues to advance, and there are more places where paper documents are used to restrict economic behavior in economic activities. The terms of paper documents are becoming more and more perfect, the content is becoming more and more complicated, and the number of pages is also increasing. . Correspondingly, the demand for reviewing paper documents and performing multiple confirmations on paper documents continues to rise. Usually the paper documents have been reviewed by the electronic documents, and the other party stamps the paper documents first, then the company will check the paper documents again before the company stamps again to ensure that the terms have not been modif...
