The measurement speed and accuracy are much better than other similar systems or techniques. In rock engineering, 3D laser scanning technique has been used in geology mapping, rock blasting, rock slope maintains, and rock fracture measurement and analyses. This paper mainly presents 3D laser scanning technique and its applications in rock fracture measurement and analyses. In this paper we present...
Rock fracture tracing is very important in many rock-engineering applications. This paper presents a new methodology for rock fracture detection, description and classification based on image processing technique and support vector machine (SVM). The developed algorithm uses a number of rock surface images those were taken by sophisticated CCD cameras. The studied algorithm processes all the images...
Mineral analysis is very important in engineering geology. It is often that a geologist analyzes minerals on an image under microscope, or by taking photos. It is difficult to recognize minerals automatically due to the complexity of mineral images. This paper presents the newly studied an image segmentation algorithm for mineral particles. The algorithm consists of image pre-processing, gray level...
Rock aperture measurement is a hot topic in many rock engineering applications. To measure rock fracture aperture using digital image processing technique accurately, it is better to divide the aperture into a number of segments first, then, measuring each of those segments. Since information of aperture is concentrated at the corners, this paper presents a corner segment algorithm for measuring rock...
This paper presents that: (1) the analysis of rock fractures are very important in many real rock engineering applications; (2) it is necessary to apply image processing techniques into multiple rock fracture analysis by considering that the rock was cut into natural blocks; and (3) the newly studied methodology is valuable for presenting multiple rock fracture, the developed algorithms have been...
