摘要: 利用边界检测、直方图滤波等图像处理技术作为对破裂岩体或含节理、裂隙岩体 的图像(数码照片)信息处理的基础,建立表征岩体中块度分布的二值化图像. 通过对二值 化图像的逐行和逐列扫描统计得到岩体块度分布的表征岩体多尺度特征的分维指数和特征块 度.

Abstract: Fractal dimension and characteristic lengths of rock masses are obtained by image processing. The edge detection and pixel scanning methods are used to acquire these parameters. From the numerical results, it is shown that when the scanning is fine enough the results are stable. So the method presented here would give reasonable values of the parameters in consideration.

Key words: rock scale information, image processing, fractal dimension
