증강현실 기반의 프리캐스트 교각의 사전시공 시뮬레이션 및 시공성 정밀도 관리방안

Abstract

Geometry control of precast members is the most important technology for modular construction. In this paper, image-basedmodeling and rendering (IBMR) technology was adopted for 3D modeling of precast elements. It is necessary to use match-casting methodfor precast post-tensioned column assembly. Preassembly using 3D models created by image processing can minimize construction error. Augmented reality devices are used to check the geometry of the segment. Laboratory-scale tests were performed. The proposed processhas been applied to the real precast bridge pier segments.
