Zusammenfassung:The present invention discloses a method for extracting 2D pipeline drawing data, which includes the steps of: preparing plan drawing data of an underground pipe, which extracts data for pipes, nodes, and valves from CAD plan drawings through pre-processing; extracting drawing data for extracting data for each type of entity used in a CAD drawing; processing the extracted data for adding data by finding a crossing point and a connected point of a pipe among the extracted entities; and matching the pipes, nodes, and valves matching the node name to a pipe data point. 본 발명은 전처리 작업을 통해 CAD 평면 도면에서 파이프, 절점 및 밸브에 대한 데이터를 추출하는 지하매설관 평면도면 데이터를 준비하는 단계와, CAD 도면에서 사용하는 엔터티 종류별 데이터를 추출하는 도면 데이터를 추출하는 단계와, 상기 추출된 엔터티 중 파이프의 교차점(crossing point) 및 연결점(connected point)을 찾아서 데이터를 추가하는 추출 데이터를 가공하는 단계와, 상기 파이프 데이터 포인트에 절점 이름을 매칭시키는 파이프와 절점, 밸브를 매칭하는 단계를 포함하는 2D 관로 도면 데이터 추출 방법을 개시한다.
