【摘要】 将多分辨分析的思想应用于表面信号的分离,用B-样条函数构造双正交小波基,并构建B-样条小波评定基准线。实验对实测的表面形貌使用多种滤波方法,并将各种方法所得的基准进行比较,证明了B-样条小波在粗糙度评定中的适用性。更多还原

【Abstract】 This text use the notion of multiresolution analysis to separate surface signal,use the B-Spline function to construct biorthogonal wavelet,and then build the B-Spline wavelet reference line.The test use various filtering method to surface texture,and compare the reference line obtained from these methods.It convinces that the B-Spline wavelet is applicable to roughness assessment.更多还原
