초록
Colmap은 혁신적인 인공지능 기술 중 하나로, 3D 재구성 작업에 있어 매우 유용한 도구로 사용된다. 또한, 이미지와 해당 메타데이터를 활용하여 세밀한 3D 모델을 구축하는 데 탁월하다. 2D 이미지, 카메라의 위치 정보, 깊이 정보 등을 결합하여 Colmap은 3D 모델을 생성한다. 이를 통해실제 세계의 객체들을 포함한 상세하고 정확한 3D 재구성을 이뤄낼 수 있다. 또한, Colmap은 대규모 데이터 세트에서 효율적으로 작동할 수 있도록 GPU를 활용하여 빠른 처리를 제공한다. 본논문에서는, 우리나라 전통탑의 2D 이미지를 수집하고, Colmap을 사용하여 3D 모델로 재구성하는방법을 제시했다. 본 연구는 우리나라의 전통적인 석탑 복원 과정에 이 기술을 적용했다. 이로써, 문화재 복원 분야에서의 Colmap의 응용 가능성을 확인했다.
Abstract
Colmap is one of the innovative artificial intelligence technologies, highly effective as a tool in 3D reconstruction tasks. Moreover, it excels at constructing intricate 3D models by utilizing images and corresponding metadata. Colmap generates 3D models by merging 2D images, camera position data, depth information, and so on. Through this, it achieves detailed and precise 3D reconstructions, inclusive of objects from the real world. Additionally, Colmap provides rapid processing by leveraging GPUs, allowing for efficient operation even within large data sets. In this paper, we have presented a method of collecting 2D images of traditional Korean towers and reconstructing them into 3D models using Colmap. This study applied this technology in the restoration process of traditional stone towers in South Korea. As a result, we confirmed the potential applicability of Colmap in the field of cultural heritage restoration.
