Detection of Water Leakage in Underground Tunnels Using Corrected Intensity Data and 3D Point Cloud of Terrestrial Laser Scanning

Detection of water leakage is one of the most important regular tasks for underground tunnel inspection. In this paper, a new method is proposed for the water leakage detection in underground tunnels by using the corrected intensity data and 3-D point cloud of a terrestrial laser scanning (TLS) sensor. In the proposed method, the distance effect on the TLS… CONTINUE READING
