摘　　要：利用图像处理中的二维傅立叶频谱分析方法对羊毛毛丛的卷曲频率和卷曲清晰度进行了理论表征和实际测量并通过对比实验对该方法的测量结果进行了理论评价与分析,结果证明该方法对毛丛卷曲特征的测量有效、客观。The wool staple crimp features, including the staple crimp frequency and the crimp definition, are indicated and measured in theory and practice by means of two - dimensional Fourier power spectrum analysis in image processing. Meanwhile, the results measured by the method are discussed and evaluated through comparing with that of other crimp testing methods. It is obvious that the method is a quick, efficient and objective one in the analysis of wool staple crimp frequency an crimp definition.
