Certificate identification model training method, certificate identification method, certificate identification system, certificate identification equipment and medium

The invention relates to the technical field of artificial intelligence, and provides a certificate identification model training and certificate identification method, system and device, and a medium. The certificate identification model training method comprises the following steps: acquiring a plurality of certificate images; adding a data label to each certificate image according to whether the certificate image contains moire features or not; the certificate images containing the data labels are grouped, an image data set containing multiple groups of image data is obtained, and each group of image data comprises multiple certificate images containing the data labels; and respectively inputting each group of image data in the image data set into a to-be-trained certificate identification model for iterative training, and updating the weight of the model based on an iterative training result to obtain a trained certificate identification model. According to the invention, whether the certificate contains
