Abstract

Spatial data is becoming very important as a medium that connects various data produced in smart cities, digital twins, autonomous driving, smart construction, and other applications. In addition, the rapid construction and update of spatial information is becoming a hot topic to satisfy the diverse needs of consumers in this field. This study developed a software prototype that can match the position of an image-based 3D building model produced without Ground Control Points using existing spatial data. As a result of applying this software to the test area, the 3D building model produced based on the image and the existing spatial data show a high positional matching rate, so that it can be widely used in applications requiring the latest 3D spatial data.

최근 스마트시티, 디지털 트윈, 자율주행, 스마트 건설 등의 분야가 발전하면서 각 분야에서 생산되는 다양한 데이터를 서로 연결하기 위한 매개체로서 공간정보의 가치가 매우 중요해지고 있다. 특히 데이터의 최신성을 위해 공간정보의 신속한 구축과 갱신이 필요하다. 본 연구에서는 정밀한 위치정확도가 이미 검증된 기구축 공간데이터를 이용하여 지상기준점 없이 제작된 영상기반 3차원 건물모델의 위치를 정합시킬 수 있는 소프트웨어 프로토타입을 개발하였다. 이 소프트웨어를 실험대상지역에 적용한 결과, 지상기준점 없이 제작된 3차원 건물모델과 기구축 공간데이터가 높은 위치 정합률을 보여 최신의 3차원 공간데이터를 필요로 하는 분야에 적용될 수 있음을 확인하였다.
