Abstract

Digital twin is a technology that creates a virtual space that replicates the real world and manages the real world efficiently by integrating the real and virtual spaces. The digital twin concept for water facilities is to effectively manage water pipes in the real world by implementing them in a virtual space and augmenting them to the interior space of the building. In the proposed method, the Unity 3D game engine is used to implement the application of digital twin technology in the interior of a building. The AR Foundation toolkit based on ARCore is used as the augmented reality technology for our Digital Twin implementation. In digital twin applications, it is essential to match the real and virtual worlds. In the proposed method, 2D image markers are used to match the real and virtual worlds. The Unity shader program is also applied to make the augmented objects visually realistic. The implementation results show that the proposed method is simple but accurate in placing water pipes in real space, and visually effective in representing water pipes on the wall.

디지털 트윈은 현실 세계를 복제한 가상 공간을 만들고 현실 공간과 가상 공간을 통합하여 효율적으로 현실 공간을 관리하는 기술이다. 건물에 설치되어 있지만 시각적으로 보이지 않는 수도관 설비를 가상 공간에 구현하고 이를 건물의 실내 공간에 증강함으로써 현실 세계의 수도관을 효과적으로 관리하는 것이 수도 설비에 대한 디지털 트윈 개념이다. 제안하는 방법에서는 Unity 3D 게임 엔진을 이용하여 건물의 실내에 디지털 트윈 기술을 적용하는 방법을 구현하며, 디지털 트윈 구현에 필요한 증강현실 기술은 ARCore 기반의 AR Foundation 툴 킷을 사용한다. 디지털 트윈 응용은 현실 세계와 가상 세계를 정합하는 것이 필수적이다. 제안하는 방법에서는 2D 이미지 마커를 이용하여 현실 세계와 가상 세계를 정합한다. 또한 증강된 오브젝트를 시각적으로 현실감 있게 표현하기 위하여 Unity 쉐이더 프로그램을 적용한다. 구현 결과는 제안하는 방법이 간단하지만 정확하게 수도관을 현실 공간에 배치하고, 시각적으로도 효과적으로 벽면 위에 수도관을 표현하는 것을 보여준다.
