Abstract

Augmented reality (AR) technology visualizes a real type object that cannot simulate in virtual reality technology by overlapping a virtual object and real object in a computer system. This study suggests a methodology and prototype system for applying AR system to rebar distribution work in a civil engineering project. Rebar work in civil engineering project is a representative activity that is progressed by empirical approach of skilled labor rather than formalized manual. AR technology improves the constructability of rebar work because AR tool can identify missing rebars and different rebars comparing with the drawings. AR system developed in this study can enhance the understanding of rebar work using 3D modeling with real image of construction site and save construction cost by reducing reconstruction work.

증강현실(Augmented Reality, AR) 기술은 현실 환경을 기반으로 컴퓨터에서 생성한 가상의 객체정보를 중첩해봄으로써 가상현실 상에서 느낄 수 없는 실감형 모델을 구현하는 기술이다. 본 연구에서는 토목공사 철근배근 작업에 증강현실 기술을 적용하는 방법론과 시스템 시제품을 구성하여 철근공사 작업의 증강현실 적용성을 검증하고 있다. 토목공사 현장의 여러 작업들 중에서 철근공사는 절차화된 매뉴얼방식보다는 숙련공의 경험적 방식에 의해 작업이 진행되는 대표적 공정이다. 이러한 공정에 증강현실을 적용하면 당초 계획도면과 비교하여 누락된 철근배근 및 상이한 배근 상태를 시각화하여 계측할 수 있으므로 시공성을 향상시킬 수 있다. 구축된 시스템은 3차원으로 모델링 된 철근객체를 실제 시공현장에 중첩하여 시각화함으로써 철근 조립공정들의 작업 이해도를 높이고, 검측단계에 활용함으로써 철근조립작업에서 발생할 수 있는 하자와 재작업으로 인한 비용증가를 억제할 수 있을 것이라 기대된다.
