钻孔图像的煤矿地质信息获取方法

Acquisition method of coal mine geological information based on borehole image

针对煤矿地质信息获取耗时且二、三维应用较少的问题,该文在总结前人研究成果的基础上,提出一种基于数字钻孔图像得到煤矿地下空间信息的方法;首先采用深度匹配算法实现全景环形孔壁图像的快速裁切;其次通过种子填充法实现多幅孔壁图像的自动无缝拼接得到完整钻孔图像;然后以此图像为底图进行地层素描以提取地下空间地质信息;最后利用提取后的信息生成二维钻孔柱状图和真实三维钻孔模型。实际应用表明,该方法可以满足矿山地质信息快速准确提取的要求。

Aiming at the time consuming problem and few applications in 2Dand 3Dof coal mine geological information acquisition,a method to extract underground space information of coal mine based on digital borehole images was proposed.Firstly,aquick cut to the panoramic annular image of borehole was made by depth matching algorithm;secondly,seed filling method was used to obtain the hole wall image by splicing the borehole images automatically and seamlessly;then this image was set as a base for formation sketch to extract geological information of underground space;finally,two-dimensional histogram drilling and true three-dimensional model were generated by extracted data.Practical application showed that the proposed method could meet the requirements to extract mine geological information quickly and accurately.
