基于视觉的物体表面质量客观评价方法的研究与应用

Study and Application of Objective Evaluation Method of Object Appearance Quality Based on Visual Perception

基于人的视觉对表面粗糙度的识别机理 ,定义了一个代表皱褶类表面的特征参数一单位面积上的不等曲率 ,介绍了推导过程。并用这个特征参数对服装表面接缝进行了客观评价 ,实验结果证明了其可行性 。

This paper defines a characteristic parameter presented puckering surface-disparity curvature of unity area based on human being's visual perception for surface roughness,which is applied to objectively evaluate seam pucker on garment surface.Experiment results a linear relationship among the parameter and subjective grades,which means a new way is put forward to measure surface roughness.
