초록

최근 실내공간에서 활동하는 인구가 증가함에 따라 3차원 실내공간정보에 대한 관심이 높아지고 있다. 실내공간정보를 포함하는 3차원 실내공간 모델링은 LoD 4 (Level of Detail 4) 수준의 객체지향 형태로 수행되고 있으며, 원시자료에 따라 준공도면, 레이저스캐닝, BIM데이터와 카메라를 이용하여 모델링 데이터를 구축할 수 있다. 3차원 실내공간 모델링을 수행하기 위해 정립된 프로세스는 실내공간 모델링 데이터 구축작업의 기반이 되며 구축된 모델링 데이터는 실내공간 보행자 내비게이션, 시설물관리 및 재난관리 등 다양한 어플리케이션에서 활용가능하다. 그러나 정립된 실내공간 모델링 프로세스 기반으로 수행되는 작업이 매우 복잡하고 모델링 작업에 많은 시간이 소비되어 효율적인 모델링을 하는데 한계가 있다. 따라서 본 연구에서는 효율적인 실내공간 모델링 수행 지원을 목적으로 원시자료의 활용도 평가를 제안한다. 기존 3차원 실내공간 모델링 프로세스 분석을 통해 활용도 평가를 위한 필요요건을 정의하고, 검증 방법을 제안한다. 또한 제안된 방법은 서울시 3차원 실내공간 모델링 프로젝트에서 사용된 준공도면을 적용하여 수행한다.

As the number of people who live indoor space has been increased, the interest in 3D indoor spatial information has been grown. Object-Oriented 3D indoor space modeling including indoor spatial information has performed in level of detail 4, and modeling data is able to be constructed based on various raw data which are as-built drawing, laser scanning, BIM data, and camera. 3D indoor space modeling has been worked based on established indoor space modeling process, and the result can be used for various application fields such as indoor space pedestrian navigation, facility management, disaster management, and so on. However, the modeling process has limitations to perform indoor space modeling efficiently, because the process is complicated and wastes time at modeling work. In this paper, we propose evaluation on practical use of raw data for 3D indoor space modeling purpose on supporting efficient indoor space modeling through analyzing the established process. Therefore, we define the requirements to evaluate the practical use of raw data and propose the verification method. In addition, as-built drawing which has been used in Seoul 3D indoor space modeling project will be applied to proposed method as a raw data.
