Abstract

The purpose of this study was to investigate the symmetry relationship between evaluation of smoothness and roughness of fabrics and the physical factors related to the evaluations, using a set of images obtained by photographing the surfaces of eight fabrics. These fabric surface images were created by setting the distance between the fabric and the camera at approximately 1 m and gradually reducing the distance for each of the eight fabrics. Based on these images, we conducted an experiment to evaluate the smoothness and roughness of fabrics on a seven-level unipolar scale. Results showed that the evaluation characteristics of fabric smoothness and roughness with consideration of the shooting distance of the fabric surface images differed for each fabric. Furthermore, analysis of the correlation between evaluation of smoothness and roughness of fabrics indicated that symmetry was not established between evaluation of smoothness and roughness of some fabrics.

织物表面图像平滑度与粗糙度评价的对称关系研究

本研究的目的是探讨织物的光滑度和粗糙度评价与评价相关的物理因素之间的对称关系，利用一组由8种织物表面拍摄的图像。这些织物表面图像是通过将织物与相机之间的距离设置为大约1米，并逐渐减少8种织物之间的距离来创建的。基于这些图像，我们进行了一个实验，在7级单极尺度上评估织物的平滑度和粗糙度。结果表明，考虑织物表面图像拍摄距离的织物光滑度和粗糙度评价特征在不同织物之间存在差异。此外，对织物的平整度评价与粗糙度评价之间的相关性分析表明，某些织物的平整度评价与粗糙度评价之间不存在对称性。
