Abstract

The embodiment of the invention provides a character recognition method and device for a vertical text image, and the method specifically comprises the steps of obtaining a vertical text image to be recognized, the vertical text image comprising at least one column of vertical texts; converting each column of vertical text into a single-row transverse text; and inputting the single-row transversetext into an end-to-end character recognition model to obtain a recognition result. Therefore, the character recognition problem of the vertical text image is solved.

Description

technical field [0001] The present invention relates to the technical field of character recognition, in particular to a character recognition method and device for vertical text images. Background technique [0002] In real work and study, people will come into contact with quite a lot of text images, such as pdf files. If these files need to be edited, OCR recognition is required to convert them into editable text such as word. At present, the general text recognition method is based on horizontal text recognition. However, there are many vertical texts in actual work, such as ancient Chinese texts, Mongolian texts, Tibetan texts, etc. For these vertical texts Saying that current text recognition methods would be powerless. Contents of the invention [0003] In view of this, the present invention provides a character recognition method and device for vertical text images to solve the problem of character recognition for vertical text images. [0004] In order to solve ...
