| 摘 要： | 针对一种基于图像处理的岩体结构面迹线半自动检测的方法进行了研究。该法的基本思路是在图像中人工指定少量难以正确识别的主要裂隙控制点,然后将图像一分为二,分别对二者进行边缘检测,得到两张包含结构面迹线和伪边缘的分段线图片,之后根据距离、角度原则分别对两张图片中的分段线进行迭代连接,最终将检测结果叠加,得到完整裂隙迹线检测结果。该法将主要裂隙与次要裂隙区域分开处理,能够更好地减少二者之间的干扰,所以能够更好地保证主次裂隙识别的完整性与正确性,因而具有更高的精确性。

| Abstract: | A semi-automatic detection method of rock mass discontinuity trace based on image processing was presented.The basic ideas are as following:A small number of main crack control points which are difficult to identify are manually designated in the image,and then the image is divided into two parts,and edge detection is carried out respectively.Two segmented line pictures including discontinuity trace and fake edge are obtained.According to the principle of distance and angle,the segmented lines in the two images are connected iteratively.Finally,the results are superposed to get the complete fissure trace detection results.This method could reduce the interference between the primary and secondary fissures by detecting them separately,and ensure the integrity and correctness of the identification of the primary and secondary fissures with higher accuracy. |
