A geometric information on roughness of rock fractures based on image processing
一种基于图像处理的岩石裂隙粗糙度几何信息算法

This paper presents a method for measuring roughness of rock fractures based on digital image processing technique. Four self-defining geometirc characteristic parameters such as the difference between the wave crest and the trough of the rock curve, the number of corner points, the number of intersection points and the width between the rock curve and the fitting straight line were got under the VC platform. The joint roughness coefficients were analyzed and quantized by geometirc characteristic parameters. By analyzing and comparing the data from experiments, we find that there are obvious relations between these four parameters and roughness coefficient, showing that the new method is simple and feasible.
