Text content extraction method and device

The invention provides a text content extraction method and device, and the method comprises the steps: carrying out the character recognition processing of a target image, and determining a marking graph containing a character identifier according to a processing result; inputting the mark graph containing the character identification into an image processing model for processing, and obtaining a reference graph which is output by the image processing model and contains prediction lines; determining mark information corresponding to the character identifier in the mark graph and line information corresponding to the predicted line in the reference graph; calculating connection parameters according to the mark information and the line information, and constructing a target relation graph corresponding to the target image based on the connection parameters; and extracting the text content in the target image by using the target relation graph, thereby improving the text integrity degree of text content extract
