摘要： 针对高炉内矿石颗粒外形不规则和边缘暗淡模糊等特性，提出了双圆比的概念，运用图像预处理、彩色形态学平滑、颗粒点定位、颗粒最大区域扩张、双圆尺度检测等方法，能够很好地对矿石颗粒尺度分布情况进行检测.对比实验表明，该算法比经典算法具有更高的准确度.

Abstract: Particle size distribution of ores can directly be used as a basis for the blast furnace process control, so it is crucial for the optimization of control dynamics and system structures. The doublecircle ratio concept and method were used to detect the particle size distribution of dim and obscure ores. The paper uses several steps to detect ores’ granularity and distribution, such as preprocessing, morphological smooth, particle positioning, largest expansion and double circle detection. A series of comparative experiments prove that this novel algorithm improves the accuracy of granulometry compared with classic methods.
