基于MATLAB的碎裂煤二维裂隙自动识别与信息提取

Cataclastic Coals with Two-dimensional Micro Crack Automatic Recognition and Information Extraction Based on MATLAB

裂隙煤系统信息获取是构造复杂区煤储层渗透性和结构强度评价的关键。基于MATLAB软件平台处理图像的优势,编程实现对构造煤典型裂隙系统的两张照片进行二值化、去杂、修复、分割等操作,得到与原裂隙信息基本一致且易于处理的新裂隙个体。在此基础上,自动提取裂隙面积、长度、平均宽度等参数,实现裂隙的定量分析。

Getting the information of cataclastic coal system is the key to evaluate the coal bed permeability of complex-tectonic area and the structural strength. By using the software of MATIAB image processing advantage, programed with typical crack system＇s photos. After binarization, removing miscellaneous points, repairing and segmentation, the new single crack with easy operation corresponded to the original cataclastic information was obtained, based on this, automatic extraction crack＇ s area, length, average width and other parameters were got to realize quantitative analysis of crack.
