Embodiment Construction

[0020] In the present disclosure, unless otherwise stated, using the terms "first", "second", etc. to describe various elements is not intended to limit the positional relationship, temporal relationship or importance relationship of these elements, and such terms are only used for Distinguishes one element from another. In some examples, the first element and the second element may refer to the same instance of the element, and in some cases, they may also refer to different instances based on contextual description.

[0021] The terminology used in describing the various described examples in this disclosure is for the purpose of describing particular examples only and is not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, there may be one or more elements. In addition, the term "and / or" used in the present disclosure covers any one and all possible combinations of the listed items.

Abstract

The disclosure provides a text image correction method, comprising: obtaining an initial image comprising a to-be-recognized object obtained by oblique shooting of a binocular camera, the binocular camera comprising a first camera and a second camera, the optical axes of the first camera and the second camera being not perpendicular to the placement surface of the to-be-recognized object, the initial image comprising a first initial image comprising a to-be-identified object and obtained by oblique shooting of the first camera and a second initial image comprising the to-be-identified object and obtained by oblique shooting of the second camera; determining a rotation matrix that the to-be-identified object rotates around a set point on the to-be-identified object to be perpendicular to and corresponding to the optical axis of the first camera; determining a 3D image including the to-be-identified object based on the first initial image and the second initial image; obtaining a rotation correction image obtained by rotating the 3D image around the set point to be perpendicular to the optical axis of the first camera by using the rotation matrix; and flattening and correcting the rotation correction image to obtain a final correction image.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a text image correction method, device, equipment and medium. Background technique [0002] In the related art, before text recognition is performed on a reading material such as a book or a magazine, the image may be corrected for bending, so as to overcome the problem that the accuracy of character recognition is affected by the bending of the reading material. However, due to the limitations of the correction algorithm itself, the text recognition effect on curved reading materials still needs to be improved. [0003] The approaches described in this section are not necessarily approaches that have been previously conceived or employed. Unless otherwise indicated, it should not be assumed that any approaches described in this section are admitted to be prior art solely by virtue of their inclusion in this section. Similarly, issues mentioned in this...
