Example Embodiment

[0020] In the present disclosure, unless otherwise stated, the term "first", "second" or the like will be used to describe the positional relationship, timing relationship or important relationship of these elements, which is used for the relationship between the various elements. A component is separated from the other element. In some examples, the first element and the second element can point to the same example of the element, and in some cases, based on the context, they can also refer to different examples.

[0021] The terms used in the description of the various described examples are merely intended to describe the purposes of specific examples. Unless the context explicitly indicates that if the number of elements is not specifically defined, the element can be one or more. Moreover, the terms "and / or" of the present disclosure encompasses any of the listed items and all possible combinations.

[0022] Readings such as books or magazines typically have a certain types...

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...
