Subject : 3D Mapping Technology of Underground Structures Specialty : Cartography and Geographic Information Engineering Name : WangJing (Signature) Instructor: Yang Yongchong (Signature) ABSTRACT Currently, underground building measurement and three-dimensional expression is a new field, three-dimensional mapping technology of domestic and foreign underground structures is relatively small, compared with the ground, three-dimensional digital topographic mapping technology mapping technology of underground structures have the same place, but due to the special environment of the underground building which, in the measurements by the conditions, the underground structures of three-dimensional mapping technology to carry out specialized research. This paper we study the definition and classification of underground structures, and then follow the split step measure control order, introduced the Total Station mapping technology, 3D laser mapping technology built drawings mapping technology, the last underground building three-dimensional expression, the main work of this paper is as follows: ⑴Discusses the definition and classification of underground buildings, Background and Significance of the underground building three-dimensional mapping technology, the status of the underground space mapping technology, mapping technologies routes of the underground buildings and raised the content of this article. ⑵According to the order of first control Scattered detailed description of the Total Station surveying and mapping underground structures, and focus on the shaft forms the ground and underground contact measurement method, as well as feature points of the top of the underground structures for the mine a well directed and well directed thinking applied to the control measurement of the underground buildings, and finally a brief introduction to the prism measurement technique. ⑶Details the use of 3D laser scanning equipment for field data collection and point cloud
