Abstract

The invention relates to the technical field of computer vision, in particular to a seal recognition method, a device, equipment and a medium. The method comprises the following steps: collecting a to-be-recognized seal image; performing character recognition on the to-be-recognized seal image to obtain recognized characters, and performing feature vector extraction on the seal image to obtain a first feature vector; feature matching is conducted on feature vectors of existing seals and the first feature vectors, and seal characters of one or more existing seals with the matching degree exceeding a first preset threshold value are obtained; and performing similarity comparison on the seal characters of one or more existing seals and the recognition characters, outputting the seal characters with the highest similarity and exceeding a second preset threshold value as an recognition result; and when the similarity does not exceed the second preset threshold value, outputting the seal character of the existing seal with the highest matching degree as the recognition result.
