Disclosed are a three-dimensional modeling apparatus of an underground structure, and a method thereof. The three-dimensional modeling apparatus of the underground structure comprises: a laser sensor for measuring the distance from a structure; a plurality of red, green, blue-distance (RGB-D) cameras installed to obtain a three-dimensional image; a horizontal support stand for mounting and fixing the laser sensor, the RGB-D cameras, and a global positioning system (GPS) module onto a safety helmet; a storage unit for storing a design drawing and a three-dimensional model of an underground structure, and second-dimensional geographic information system (GIS) data; and a control unit for generating a depth map image through the distance and the three-dimensional image inputted by the laser sensor and the RGB-D cameras to be combined with the design drawing of the underground structure stored in the storage unit so as to generate the three-dimensional model of the underground structure, and storing two-dimensional GIS data extracted in a GIS shape in the storage unit by converting the three-dimensional model of the underground structure into a two-dimensional coordinate. |
