| 摘 要： | 通过对SOLIDWORK软件设计的CAD模型数据特点及软件本身自动成环检测技术,以曲线可以用相交面来替代为例,构造出相交曲面的CAD表示冗余信息,通过修改冗余信息进行水印嵌入;另外还提出可以将水印信息嵌入在CAD模型颜色等属性和CAD模型数据编码冗余信息中,具体嵌入方法可以借鉴已有图像水印方法.

| Abstract: | This paper describes a new method for watermarking CAD model designed with solidwork.The method is intended for verification purposes and is based on constructing curvessurfaces redundancy watermarking.The color attribute and encodement of CAD model are also considered to be watermarked.For how to modify the redundancy,the image watermarking algorithm can be used for reference.The robustness against some attacks are anlaysized.The attacks include geometrical transform,modifying character,and modifying color attribute. |
