【摘要】 本文基于纹理触觉的多尺度和多频率特征,将织物的表面形貌图经过傅里叶变换后得到组成表面纹理的谐波最高峰和相应空间周期两个指标。然后,按这两个指标、粗糙度(SMD)和纹理空间周期对织物粗糙感进行排序,并比较分析这些排序与触觉评价排序值的一致性,发现表面纹理明显的织物触觉粗糙感主要源于纹理空间周期。更多还原

【Abstract】 On the basis of multi-scale and multi-frequency about tactile textures, Fourier method was used to transform time-domain signal of surface morphology to frequency domain, and obtained the peak of harmonics and its corresponding spatial period. Each of these two indexes as well as SMD and the texture spatial period was selected to rank fabric roughness, and then each of four ranking sets was used to test consistency with rank set of perceived roughness magnitude for all fabric specimens. The result showed that roughness sensation of fabrics with observable textures depends on the spatial period consisted of surface patterns, and has relatively low correlation with the height cues of surface profile.更多还原
