Seal recognition method and system based on deep learning and storage medium

The invention discloses a seal recognition method and system based on deep learning and a storage medium, belongs to the technical field of machine vision, and aims to solve the technical problems of few seal recognition scenes, poor seal fan-shaped character correction effect and low character recognition accuracy.According to the technical scheme, he method includes: acquiring a to-be-recognized image; detecting a seal in the to-be-recognized image by using the target detection model, and obtaining coordinate information and a seal type corresponding to the seal in the to-be-recognized image; according to the coordinate information corresponding to the seal in the to-be-recognized image, cutting out the to-be-recognized seal image; using the image rotation angle classification model to recognize the rotation angle of the to-be-recognized seal image, and correcting the to-be-recognized seal image according to the rotation angle; detecting characters in the corrected to-be-recognized seal image by using a cha
