Embodiment Construction

[0075] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0076] In order to improve the extraction efficiency of text elements, the inventor of this case conducted research, and the initial idea was:

[0077] Based on OCR (Optical Character Recognition, Optical Character Recognition) technology, the text content of the text area in the text image is acquired, and then elements are extracted from the image based on the acquired text content.

[0078] However, extracting features from an image based only on the text content of the text regi...

Abstract

The invention discloses a text element extraction method, related equipment and a readable storage medium. The method comprises the following steps: after acquiring an image of a text to be subjected to element extraction, determining spatial information of each text region in the image and text content of each text region; and then, on the basis of the spatial information of each text region in the image and the text content of each text region, performing element extraction on the image to obtain the elements of the text, so that the efficiency is improved compared with a mode of manually reading and extracting the text elements.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, relates to a method for extracting text elements, related equipment and a readable storage medium. Background technique [0002] Key information in texts (such as legal documents, news releases, bills, etc.) is generally called text elements. For example, the buyer and seller in the invoice can be invoice elements; the buyer and seller, cargo information, payment amount, payment method, delivery method, and liability for breach of contract in the contract can be contract elements. [0003] At present, when text elements need to be used, they are often extracted by manual reading. However, the text contains a lot of information, and there is a problem of low efficiency in extracting text elements by manual reading. [0004] Therefore, how to improve the extraction efficiency of text elements has become an urgent technical problem to be solved by those ski...
