利用图像识别技术提取粗粒煤图像的物理特征

基于图像处理原理,利用图像识别软件,对粗颗粒煤图像进行分析,提取了煤颗粒形状系数、直径和灰度值物理特征值,对图像特征参数进行分析。量化分析了3￣2mm、2￣1mm、1￣0.25mm粒度级别浮沉实验中各个密度级对应的煤颗粒平均直径关系、平均灰度值关系、平均形状系数关系。 Based on the principium of picture management,we analyzed the coarse coal picture and characteristic parameter of this picture to extracted some physical features,such as particle form parameter of coal,diameter and gray-scale value using some picture identify software.Quantify analysis of the average diameter connection,average gray-scale value connection,and average form coefficient connection of the corresponding coal particles in the Float-and-sink size fraction experiment of some size levels which were 3~2mm,2~1mm and 1~0.25mm had been done in this paper
