Classification: CPC G | IPC G

Claim 12:
13. An apparatus for recognizing an imaged information-bearing medium, comprising:
a distortion correction module configured to acquire a first image of the imaged information-bearing medium, wherein in order to acquire a first image of the imaged information-bearing medium, the distortion correction module is configured to:
perform target detection and correction on the imaged information-bearing medium in an original image based on the acquired original image to acquire the first image;

a text recognition module configured to perform text recognition on the first image to acquire a text content of the imaged information-bearing medium;
an imaged information-bearing medium classification module configured to classify the imaged information-bearing medium to acquire a type of the imaged information-bearing medium; and
a text archiving module configured to archive the text content according to the type,
wherein the text recognition module is further configured to:
perform text detection on the first image to acquire multiple second images; and
recognize the multiple second images with a preset text recognition network model to acquire the text content of the imaged information-bearing medium;

wherein in order to perform target detection and correction on the imaged information-bearing medium in an original image based on the acquired original image to acquire the first image, the distortion correction module is further configured to:
perform image binarization based on the acquired original image;
perform edge detection to acquire an outline of the largest rectangle in the original image, or perform straight line detection to acquire groups of a horizontal straight line set and a vertical straight line set, and merge approximate parallel lines to determine an optimal boundary and vertices of the imaged information-bearing medium;
segment the first image from the original image by perspective transformation.
