【摘要】 将数字图像处理技术引入到对煤矿顶板岩石裂纹图像的分析当中,这种通过图像研究裂纹的方法不依赖具体的岩石岩性及其力学特征。首先对裂纹图像进行多分辨率小波变换,分析图像的不同频带所包含的信息,接着对裂纹图像实现边缘提取,为图像的定量测量提供依据。更多还原

【Abstract】 Digital image processing technology was introduced to the research on crack image of roof rock in this paper,which is independent from lithology and mechanical characteristics of certain rocks.Firstly,the crack image would be divided into different frequency band contain different informations by multi-resolution wavelet transform,subsequently,the edge extraction of the image that provide a base for quantitative measurement of the image would be accomplished.更多还原
