Embodiment Construction

[0042] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0043] For some multi-length text recognition scenarios, such as long pictures, books, etc., a single photo cannot capture the full picture of the scene to be recognized. Related technologies usually need to take pictures in blocks to obtain a collection of images in the entire scene, and then Then perform OCR recognition on them separately, and finally need to manually sort and process the r...

Abstract

The invention provides a text recognition method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a to-be-recognized video, and determining each key frame in the to-be-recognized video; carrying out shooting state classification on each key frame to obtain a shooting state of each key frame; and based on the shooting state of each key frame, integrating the candidate recognition texts of the overlapping region in each key frame to obtain a recognition text of the to-be-recognized video. According to the method and device, the electronic equipment and the storage medium provided by the invention, full-view collection is carried out on a multi-space scene in a video recording form, so that the problem of missing collection in the multi-space scene is avoided, the to-be-recognized video contains a collection sequence, manual sorting is not needed, and the manual demand of text recognition is reduced. Besides, the candidate recognition texts of the overlapping region are integrated based on the shooting state of each key frame, so that automatic text integration for the overlapping region is realized, and the reliability of the recognition texts is ensured.

Description

technical field [0001] The present invention relates to the technical field of computer vision, in particular to a text recognition method, device, electronic equipment and storage medium. Background technique [0002] With the development of science and technology, OCR (Optical Character Recognition, Optical Character Recognition) technology has been widely used in people's life and work. [0003] However, for some multi-length text recognition scenarios, such as long pictures, books, etc., a single photo cannot capture the full picture of the scene to be recognized, and it may be necessary to take multiple photos and perform text recognition separately. The text recognition results of the whole scene can only be obtained by manually sorting the recognition texts of multiple photos. [0004] Considering that the content in multiple photos taken for a scene may overlap or be missing, manual processing is required after text recognition, resulting in an increase in labor cos...
