WATERMARK EMBEDDING METHOD AND DEVICE, TERMINAL, AND STORAGE MEDIUM

Title:

WATERMARK EMBEDDING METHOD AND DEVICE, TERMINAL, AND STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2020/078323

Kind Code:

A1

Abstract:

A watermark embedding method and device, a terminal, and a storage medium, relating to the technical field of information. The method is applicable to the field of three-dimensional (3D), by merging vertex data of an original 3D model and a 3D watermark, and merging 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 that the effect of seamlessly embedding the 3D watermark into the original 3D model is achieved, and the appearance of the original 3D 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 3D model, and ensuring the display effect of the 3D model. Furthermore, the function of encrypting and embedding 3D watermark can be achieved, and the 3D watermark cannot be easily removed or modified, and the copyright of the 3D model can be effectively guaranteed, so that such a digital asset of the 3D model can be popularized better.
