摘要：

在对比多种岩石表面图像特征提取的基础上，提出了岩石表面图像中节理特征的提取方法，包括图像的增强、二值化、边缘提取、Hough变换等，提出了3个限制条件，以剔除提取的节理特征冗余线段，并给出了处理依据和流程.同时，编写相应的软件以对所提方法的可行性进行验证.结果表明，经所提线段分类与合并方法处理后，冗余线段的重复率大幅降低，其结果能够准确反映岩石表面裂隙特征的分布情况.

Abstract:

Basing on the comparison of several methods, this paper proposed systematic steps in extraction the features of rock surface image including image enhancement， binarization, edge extracting, Hough trasformation,etc. Besides, it proposed 3 restrictive conditions to reject the redundant line segments and gave the corresponding processing flow. In addition, it developed the software to test the feasibility of the method simultaneously. The result showed that the repetition rate of the line segments reduced significantly, which could indicate the distribution of the joints more precisely.
 

Key words: rock, surface image, joint feature, Hough transform, redundant line segment
