Problems solved by technology
[0002] Due to the special application scenarios of letters of credit, there is almost no dedicated recognition engine for letters of credit in the industry. The existing letter of credit recognition usually adopts manual entry and manual verification, or uses a general character recognition engine, such as the tesseract engine. Or a general OCR recognition model based on deep learning
[0003] However, due to the complex content of the letter of credit format, the dense text, and the need to judge whether the check box is checked or blacked out, there are two formats, form and non-form, and the existing identification technology solutions cannot recognize the complex structure of the letter of credit. Accurately extracting the layout, it is also impossible to accurately locate the long text of the letter of credit

The invention relates to a credit card identification method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a credit card image to be identified; segmenting the to-be-identified credit card image to obtain a plurality of text regions; performing character recognition on the text area to obtain a recognition result of the text area; and performing post-processing on the recognition result of the text region according to a preset rule to obtain structured target information. By adopting the method, accurate identification of the credit card image can be realized.
