Embodiment Construction

[0046] The inventor found in the research on character recognition technology that for multi-frame text line recognition, after obtaining multiple images including the same text line, OCR can be used to perform character recognition on each image respectively to obtain the character recognition results; and then according to preset rules, the character recognition results of all images are combined to obtain the character recognition results of the text line. However, because the text line may have different defects (such as occlusion, displacement, distortion, missing characters, etc.) in different images, the character recognition results of these images are inaccurate, so that the character recognition results of these images are integrated. The character recognition result is also inaccurate, which leads to low character recognition accuracy for multi-frame text line recognition.

[0047] Based on the above findings, in order to solve the technical problems in the backgrou...

Abstract

The invention discloses a character recognition method and related equipment thereof, and the method comprises the steps: after obtaining a plurality of to-be-recognized images including the same character information, determining a coding feature corresponding to a to-be-recognized text according to the plurality of to-be-recognized images, wherein the coding feature corresponding to the to-be-recognized text is used for representing character information carried by the plurality of to-be-recognized images; and decoding the coding feature corresponding to the to-be-recognized text to obtain a character recognition result of the to-be-recognized text. Visibly, the coding features corresponding to the to-be-recognized text can accurately represent the character information carried by all the to-be-recognized images, so that the coding features corresponding to the to-be-recognized text can more accurately represent each character in the to-be-recognized text, therefore, the character recognition result of the to-be-recognized text determined based on the coding feature corresponding to the to-be-recognized text is more accurate, and the character recognition accuracy of multi-frame text line recognition is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a character recognition method and related equipment. Background technique [0002] With the development of character recognition technology, the application range of character recognition technology is getting wider and wider. Among them, the character recognition technology is used to perform recognition processing on characters appearing in an image. [0003] However, due to defects in some character recognition technologies (such as optical character recognition (Optical Character Recognition, OCR) and other technologies), the recognition of these character recognition technologies in some application scenarios (such as application scenarios such as multi-frame text line recognition) is accurate. Sex is lower. Wherein, "multi-frame text line recognition" refers to the recognition of the same text line appearing in multiple images (especially multiple fram...
