摘要
阐述了分形与分形维数的定义 ,给出了铁谱磨粒分形维数和无标度区间的计算原理。编制了磨粒图像处理及磨粒分维计算的计算程序 ,并以片状磨粒为实例 ,提取了该磨粒的轮廓分维特征、磨粒表面纹理特征、表面纹理方向特征与磨粒表面间隙度特征四个特征值 ,为有效识别磨粒提供科学依据。
The definition of the fractal and fractal dimension were expatiated, the calculation principle of fractal dimension was set forth. The debris image processing program and debris fractal dimension calculating program were designed. Taking the slice debris as an example four characteristic value such as boundary fractal dimension, debris texture fractal dimension, texture direction fractal dimension and clearance value were extracted. The extraction provides scientific bases for recognizing debris effectively.
