Abstract

The invention provides a watermark embedding method, device and terminal and a storage medium, and belongs to the field of information technology. The present application provides a watermark embedding method suitable for the 3D field, By merging the original 3D model and the vertex data of 3D watermark, merging the material data of the original 3D model and 3D watermark, the original 3D model andthe 3D watermark can be synthesized into a 3D model, Thus, the effect of seamlessly embedding the three-dimensional watermark into the original three-dimensional model is realized, and the appearanceof the original three-dimensional model can remain unchanged before and after embedding the watermark, thereby avoiding the influence of the embedding of the watermark on the appearance and the use value of the three-dimensional model, and ensuring the display effect of the three-dimensional model. Furthermore, the function of encrypting and embedding 3D watermark can be realized, and the 3D watermark cannot be easily removed or modified, and the copyright of 3D model can be effectively guaranteed, so that the digital asset of 3D model can be popularized better.

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...
