WIPO Patent Application WO/2020/181834
Kind Code:
A1
Abstract:
A method and apparatus for identifying a card number, a storage medium, and an electronic device. The method comprises: obtaining distribution format information of a character bit of a card number sequence, the distribution format information comprising character bit spacing information of the card number sequence (S11); identifying a character sequence in a target image by means of a pre-trained neural network model, and obtaining character bit spacing information of the identified character sequence (S12); determining whether the character bit spacing information in the identified character sequence is consistent with the character bit spacing information in the obtained distribution format information (S13); and if the character bit spacing information in the character sequence is consistent with the character bit spacing information in the obtained distribution format information, determining that the identified character sequence is a target card number (S14).
