Abstract

Underground lifelines such as water supply/sewer pipe, power cable and gas pipe are indispensable facilities to the life of urban society. These lifelines have been constructed long time ago and buried positioning information is not precisely recorded. Moreover, they have been concentrated on the narrow area and are complicatedly entangled in 3-dimension. In the fourth industrial revolution, a 3-dimensional visualization for underground lifelines is strongly required, and a database (D/B) with precise positioning information should be preceded. In this study, image processing technology for precise positioning of underground buried lifelines is introduced, which is able to build the database more accurately, efficiently and practically.

지하에 묻혀 있는 상·하수도관, 전력시설, 가스관, 통신시설 등의 시설물들은 국민생활에 필수적인 도시기반시설이다. 이러한 시설물들의 위치 정보가 상당히 누락되어 있으며, 시설물들의 종류가 다양하고 좁은 공간에 집중적으로 매설되어 있어 3차원적으로 매우 복잡하게 얽혀있다. 4차 산업혁명과 더불어 지하 매설관의 정확한 위치정보와 속성정보들을 3차원적으로 시각화하여 전달하는 것이 요구되며, 여기에는 정확한 D/B 구축이 선행되어야 한다. 따라서 본 연구에서는 지하매설관의 3차원 시각화를 위한 D/B 구축을 정확하고 경제적이며 현장 적용이 가능한 기법을 소개하고자 한다.
