Text recognition method for table certificate image and computing equipment

Abstract

The embodiment of the invention provides a text recognition method for a table certificate image and computing equipment, and the method comprises the steps that the text content recognition of any type of table certificate image is carried out, first text content is determined, when the number of the character strings of the first text line in the first text content is different from the number of the key fields of the table certificate of the type, any character string of the first text line and each character string in the second text line are spliced, the spliced character strings are verified, and when any spliced character string conforms to the text content rule of any key field in the table certificate of the type, the spliced character string is determined as the text content of the key field, so that the text content of each key field can be determined. Therefore, the scheme can effectively improve the accuracy of identifying the text content in the table certificate image, and reduce the cost consumed by maintaining different content templates.

Description

technical field [0001] Embodiments of the present invention relate to the field of financial technology (Fintech), and in particular to a text recognition method and computing equipment for form certificate image documents. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field, and the traditional financial industry is gradually transforming into financial technology. However, due to the security and real-time requirements of the financial industry, higher requirements are also placed on technology. In the financial field, when users handle financial services (such as loan business, etc.), in order to ensure the safety of financial business operations, users are required to upload relevant certificate images for auxiliary review. At this time, users are required to upload their own relevant certificate images. , such as uploading your own housing property certificate image, motor vehicle regis...

AI Technical Summary

Problems solved by technology

Specifically, for a certain type of form certificate image uploaded by a certain user, when performing recognition processing on this type of form certificate image, it may first be based on the four corners of each cell of the type of form certificate The coordinate value is segmented for each cell, and then OCR recognition is performed for each segmented cell to obtain the text content in each cell, and then the text content identified for each cell is analyzed through the content template and structured processing, so that the complete content information corresponding to each key field in this type of form certificate can be obtained. However, this solution is due to scanning deviation, shooting deviation, or The position of the fields in this type of form certificate image changes, so when each cell is segmented according to the coordinate values ​​of the four corners of each cell, the segmented cells will appear to be inaccurate. As a result, the text content corresponding to at least one key field identified is also inaccurate

Among them, since the existing scheme configures a content template for each type of form certificate that meets the content format requirements of the type of form certificate, and the content template corresponding to each type of form certificate is fixed, in When the content in a certain type of form certificate changes, it is necessary to redesign and develop the content template corresponding to this type of certificate, so the versatility is poor and the maintenance cost is high

For example, for house property right certificates, the content of the house property right certificates defined in different cities will vary greatly, so it is necessary to configure a content template for the house property right certificates defined in each city, which will lead to house The content template corresponding to the property right certificate has a long development cycle and high labor costs
