Abstract  

In response to the lack of quantitative characterization methods of surface morphology in the study of microscopic properties and functional mechanism of scraped surfaces, the 3D-motif method was used to characterize the scraped surface morphology. The scraped surface was measured by using LI-3 contact three-dimensional surface morphology measuring instrument, and the two-dimensional grayscale image of the scraped surface was generated by three-dimensional point cloud data. Then, according to the definition of catchment basin in 3D-motif method, the motif segmentation and merging for the grayscale image of scraped surface were conducted by using watershed algorithm. Taking the overall texture region motif segmentation results of scraped surfaces with different precision levels as the object, the feature saliency was defined, and six motif parameters, including depth, area, direction angle, anisotropy rate, flatness coefficient and feature saliency, were extracted and calculated for the scraped surface on two different area scales (25 mm2 and 0.25 mm2). Combined with the distribution of some motif parameters and the change trend of the number of motif, the scraped surface was characterized and analyzed from the dimension and morphology of the morphological features, achieving the complete characterization of the three-dimensional morphology of the scraped surface with fewer parameters. The results can provide a theoretical basis for further analysis of the microscopic properties of scraping surfaces.

Key words： scraped surface      3D-motif method      surface morphology      watershed algorithm

基于3D-motif法的刮研表面形貌表征

针对刮研表面微观特性和功能机理研究中缺少表面形貌量化表征方法的问题，采用3D-motif法对刮研表面形貌进行表征。使用LI-3型接触式三维表面形貌测量仪对刮研表面进行测量，并利用三维点云数据生成刮研表面的二维灰度图像。然后，根据3D-motif法中集水盆地的定义，采用分水岭算法对刮研表面的灰度图像进行motif分割与合并。以不同精度等级的刮研表面的整体纹理区域motif分割结果为对象，定义了特征显著度并提取计算了刮研表面在2种不同面积尺度（25 mm2和0.25 mm2）上的深度、面积、方向角、各向异性率、扁平系数和特征显著度等6项motif参数。结合部分motif参数的分布情况和motif数量的变化趋势，从形貌特征的尺寸和形态两个方面对刮研表面进行了表征和分析，实现了以较少参数完整表征刮研表面的三维形貌。研究结果可为后续刮研表面微观特性的深入分析提供理论基础。
