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 that for a 3D laser image, the large scale part and surface roughness can be re-constructed by directly using depth information from laser scanning data; and the more detailed information or micro fractures (fracture network) can be detected by using some smart image segmentation algorithms. Some experiments and tests are illustrated for the above description.
