摘　　要：针对现有煤岩识别方法存在煤岩界面传感器结构复杂、可靠性差、普适性差等问题,提出了一种基于机器视觉的煤岩界面识别系统设计方案,给出了系统总体结构,分析了系统识别煤岩界面的工作原理,重点讨论了图像特征选取和分类器的设计。该系统根据灰度共生矩阵理论提取煤岩图像的22种纹理特征,采用增l减r法搜索出优选特征,最后运用线性函数判别法构建煤岩分类器模型。实验结果表明,该系统的煤岩分类器模型性能稳定,具有较强的识别能力。In view of problems that coal-rock interface sensor has complicated structure, low reliability and universality in existing coal-rock identification method, the paper proposed a solution of coal-rock interface identification system based on machine vision. It gave general structure of the system, analyzed its working principle and focused on discussion of image feature selection and classifier design. The system extracts 22 textures of coal-rock images according to the theory of gray-level co-occurrence matrix, employs method of increasing l and decreasing r to search the optimized features, and builds coal-rock classifier model by linear function recognition. The experiment results show that the coal-rock classifier model of the system has stable performances and strong identification ability.
