摘要
数字水印技术为网络环境下的三维模型提供版权保护。介绍三维模型数字水印的特征、分类及其攻击技术,重点分析三维点云模型、三维网格模型、参数曲面模型、体数据模型数字水印技术以及三维模型数字水印算法性能评价的研究现状,归纳、总结出三维模型数字水印技术的研究难点以及需要深入研究的问题。
Digital watermarking technology has provided a copyright protection for 3D models at the network.The characteristics,classifications of the digital watermarks for 3D models and the techniques of attack to them are briefly illustrated.The present studies and functional evaluation of watermarks of all kinds including point clouds model,mesh model,parametric surface model and body data model are analyzed.The difficulties and matters of 3D model watermarking which need further study are finally concluded.
