As the utilization range of smart devices for infrastructure has widen its application owing to flourishing of smart devices, studies on the technologies to graft IT onto underground utilities are actively carried out. In particular, as underground utilities have a characteristic of invisibility, studies on a management system converged with augmented reality are demanded for the efficient management in underground utilities. Accordingly, in this paper, we build a database of underground

... es in order to produce accurate locations and information about underground utilities in a visualized form, and by analyzing the data, build a system which automatically generates cross section of the underground utility at the location where the user requires. Also, we provide the user with efficiency in identifying accurate locations of the underground utility and in information management by producing the exact location of the underground utility as data on the basis of augmented reality and by visualizing it in realistic data.
