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 containing holograms; segmenting all the certificate images into a plurality of image blocks according to a set interception size and a set step length in a sliding manner; adding a data label to each image block according to whether the image blocks contain hologram features or not; grouping the image blocks containing the data labels to obtain an image block data set containing multiple groups of image block data; and respectively inputting each group of image block data in the image block 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 ide
