초록

건물은 3차원 도시 모델링, 지형분석, 생활정보, 항법시스템 및 LBS(Location Based Service) 등 응용목적에 따라 정보의 최신성이 특히 중요시 되는 객체로써, 해당정보의 빠른 수집과 갱신에 대한 요구가 증가하고 있다. 본 연구에서는 HSI 컬러모델을 활용하여 항공정사영상 및 항공 LiDAR 자료로부터 도심지 건물에 대한 3차원 공간정보를 추출하기 위한 시스템 개발을 목적으로 하고 있다. 특히 HSI 컬러모델, 재귀적 역행 알고리즘 및 미로찾기 알고리즘을 활용하여 영상으로부터 특정 건물의 외곽선을 추출하고 건물폴리곤을 생성하는 영상정보처리 알고리즘을 제시하였고 영상분할에 있어 HSI 컬러모델의 효용성을 제시하였다.

The building information should be up-to-date information and propagated rapidly for urban modeling, terrain analysis, life information, navigational system, and location-based services(LBS), hence the most recent and updated data of the building information have been required of researchers. This paper presents the developed system to extract the 3-dimension spatial information from aerial orthoimage and LiDAR data of HSI color model. In particular, this paper presents the image processing algorithm to extract the outline of specific buildings and generate the building polygon from the image using HIS color model, recursive backtracking algorithm and the search maze algorithm. Also, this paper shows the effectivity of the HIS color model in the image segmentation.
