摘　　要：提出了将成熟的二维数字水印技术运用到三维模型水印的思想。鉴于寻找三维模型几何与拓扑不变量的难度,提出了将三维数据转换到二维空间,直接运用二维水印算法。利用平面参数化建模方法,把原始几何信号转换成具有相同频谱特性的平面信号,实现了基于网格平面化的三维数字水印算法。The concept of applying the mature 2D digital watermarking technology to 3D watermarking was presented. Due to the difficulty of Geometric invariants in 3D mesh watermarking, the method to convert 3D data into 2D data by directly applying the 2D watermarking method was put forward. This paper shows that turning an original geometric signal into a surface signal with the same frequency by applying the method of complanation can realize the application of 3D watermarking algorithm based on mesh complanation.
