Watermark embedding method, device, terminal and storage medium

Abstract

The application provides a watermark embedding method, device, terminal and storage medium, belonging to the field of information technology. This application provides a watermark embedding method suitable for the 3D field. By merging the original 3D model and the vertex data of the 3D watermark, and merging the material data of the original 3D model and the 3D watermark, the original 3D model and the 3D watermark can be synthesized into a 3D model. , so as to achieve the effect of seamlessly embedding the 3D watermark into the original 3D model. At the same time, the appearance of the original 3D model can remain unchanged before and after embedding the watermark, thereby avoiding the impact of the embedding of the watermark on the appearance and use value of the 3D model, ensuring that the 3D The display effect of the model. Furthermore, the function of encrypting and embedding the 3D watermark can be realized, and the 3D watermark cannot be easily removed or modified, effectively guaranteeing the copyright of the 3D model, thereby better promoting the digital asset of the 3D model.

Description

technical field

[0001] The present application relates to the field of information technology, in particular to a watermark embedding method, device, terminal and storage medium. Background technique

[0002] With the development of information technology, the method of embedding watermarks can be adopted, and information such as creators and copyright owners can be used as watermarks, and embedded into digital carriers such as images, videos, and documents according to certain rules, so that digital carriers can carry watermarks. It can be identified and recognized by users, thereby protecting the copyright of the digital carrier, and not affecting the use value of the digital carrier itself.

[0003] For the case where the digital carrier is an image, a patchwork (English: Patchwork) algorithm can be used to embed a two-dimensional watermark into the original two-dimensional image. Specifically, pixel point A and pixel point B are randomly selected from the original two-d...
