Abstract: 7401 air defense tunnel was built in Zhengzhou in 1960s and 1970s. It is mainly used to prevent war air strikes. Due to its disrepair, some of the air defense tunnels have collapsed, and there is water seepage in rainy season. Based on the detailed investigation of 7401 air defense tunnel, the position, spatial dimension, slope and damaged area of 7401 air defense tunnel are accurately measured by Trimble SX10 3D scanning system. It provides data basis for 7401 air defense tunnel repair.

Key words: Trimble image scanner SX10, air raid shelter, point cloud data, measurement
