A Tunnel Crack Extraction Method Based on Point Cloud
Tunnel cracks, water seepage, stage-shift deformation and other problems will have a great impact on the safe use of the tunnel, among which the accidents caused by tunnel cracks account for a large proportion. Therefore, regular detection of tunnel cracks is needed. The traditional manual detection method is less efficient and easy to produce missed detection. With the rapid development of 3D laser scanning technology, it can be used in the extraction of tunnel cracks. In this paper, the tunnel point cloud processing, using CTA algorithm combined with edge detection to achieve rapid detection of tunnel cracks, finally using the method of connected domain analysis to extract the location of the disease.
