Certificate picture generation method, device and equipment, and storage medium

Abstract

The invention relates to the field of artificial intelligence, discloses a certificate picture generation method, device and equipment and a storage medium, which are used for improving the accuracy of generating a certificate picture conforming to a real scene. The certificate picture generation method comprises the steps of obtaining a sample certificate picture, wherein the sample certificate picture comprises sample text data and sample background data; using a picture similarity comparison algorithm for forming certificate background data and certificate character data based on the sample certificate picture, and the certificate character data comprising character language data and font style data; writing the certificate text data into the random position of the certificate background data to generate an initial certificate picture; preprocessing the initial certificate picture to generate a plurality of preprocessed certificate pictures; and adopting a preset random scaling function to perform multiple times of random scaling on the plurality of preprocessed certificate pictures, so that a plurality of target certificate picture groups can be generated. In addition, the invention also relates to a blockchain technology, and the sample certificate picture can be stored in the blockchain.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device, equipment and storage medium for generating a certificate picture. Background technique [0002] With the development of society, various industries are involved in certificate pictures, and the certificates can be ID card pictures, membership card certificate pictures, work certificate pictures and student certificate pictures, etc. Therefore, many application scenarios will use the model to recognize the ID picture. [0003] In the existing technology, there are more and more detection and recognition algorithms for various types of certificates. Usually, a large number of certificate pictures are used to train the certificate detection model and carry out certificate recognition. Since the certificate detection model needs to use training data, that is, the certificate pictures have relatively high High privacy and high security, the process...

Problems solved by technology

[0003] In the existing technology, there are more and more detection and recognition algorithms for various types of certificates. Usually, a large number of certificate pictures are used to train the certificate detection model and carry out certificate recognition. Since the certificate detection model needs to use training data, that is, the certificate pictures have relatively high High privacy and high security, the process of obtaining is more difficult, so the way of generating numbers is used to generate ID pictures

However, when generating ID images, it is unable to meet the generation requirements of multiple languages ​​and IDs, resulting in a low accuracy rate of generating ID images that conform to real scenarios.
