【摘要】 介绍了小波分析理论在曲面去噪中的应用,在所设计的原始曲面上随机设置噪声,对含噪声的原始曲面型值点数据进行Hilbert扫描和小波分解,提取低频分量,再应用Unigraphics软件中的NURBS完成曲面重构,并对曲面重构的精度和效率进行了分析、验证。更多还原

【Abstract】 The paper introduces the application of wavelet analysis in the surface de-noising,a large amount of noises are randomly extracted from the constructed original surface that are analyzed by using Hilbert curve and wavelet analysis,and lower frequency component is extracted,then the surface are reconstructed by NURBS in Unigraphics,it’s efficiency and precision are analyzed and validated.更多还原
