Problems solved by technology

However, due to the attenuation of the edge resolution of the camera lens, the sharpness of the edge area of ​​the image captured by the camera is lower than that of the central area, which makes the current OCR recognition scheme reduce the recognition accuracy of the edge area of ​​​​the image captured by the camera.
[0004] It can be seen that when the text to be recognized is located at the edge of the image, the recognition effect of the current OCR recognition scheme is poor. Therefore, it is urgent to provide an image processing scheme that can improve the text recognition effect when the text to be recognized is located at the edge of the image.

Abstract

The embodiment of the invention relates to an image processing method, a device, equipment and a storage medium. In at least one embodiment of the disclosure, the position of the object used for indicating the to-be-recognized text in the first image can be determined through the first image collected by the image collection device, and then the pose of the image collection device is adjusted in combination with the position of the object, so that the central area of the field of view of the image collection device can cover the to-be-recognized text. Therefore, after the pose of the image collection device is adjusted, the second image collected by the image collection device again is collected, and the to-be-recognized text in the second image is located in the central area of the field of view of the image collection device, so that the to-be-recognized text is prevented from being located in the edge area of the field of view and is not influenced by resolution attenuation of a lens edge. The text recognized based on the second image is more accurate, and the text recognition effect is improved.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of text recognition, and in particular to an image processing method, device, equipment, and storage medium. Background technique [0002] OCR (Optical Character Recognition, Optical Character Recognition) means that an electronic device (such as a scanner or a digital camera) checks characters printed on paper, determines its shape by detecting dark and bright patterns, and then uses character recognition to translate the shape into a computer text process. [0003] In the current OCR recognition process, a fixed-focus camera or a zoom camera is usually used to collect images, and then recognize text information in the images. However, due to the attenuation of the edge resolution of the camera lens, the definition of the edge area of ​​the image captured by the camera is lower than that of the central area, which makes the current OCR recognition scheme reduce the accuracy of edge a...
