멀티 디스플레이 시스템을 이용한 농업용 사회기반시설물 진단법 = Agricultural infrastructure health inspection using multi-display system

다국어 초록 (Multilingual Abstract)

Since construction materials employed to construct the infrastructure are often exposed to water and moisture, the life of the infrastructure is rapidly reduced than originally expected due to their aging acceleration. In particular, the surfaces of agricultural infrastructure, which cannot avoid contact with water, deteriorate faster than other infrastructures because moss and moisture-saturated sediments make them quickly deteriorate. Therefore, the inspection of agricultural infrastructure should be frequently and periodically performed. However, the existing infrastructure damage inspection methods are labor-intensive and huge indirect cost loss inevitable. Therefore, using a digital twin technology and a multi-display system, a new method is introduced that can detect damages to the agricultural infrastructures indoors rather than in the field. The multi-display system was operated on the BIM CAVE application developed by Dr. Julian Kang of Texas A&M University after revising the existing BIM CAVE application source code to be compatible with Autodesk Navisworks 2022. For producing a 3D model of agricultural infrastructure, aerial photography was performed using a drone with an ultra-high-definition camera attached. Also, a digitally twined 3D model of the infrastructure that reflected its on-site condition was created using photogrammetry based on taken photos. A simple survey (Kangwon National University IRB 2022-01-005-001) was conducted to investigate whether or not the proposed method enhances the sense of presence or the perception when the user tries to look for the damages to the agricultural infrastructure in the virtual environment. As a result, the proposed method could be an advanced infrastructure health monitoring approach if some minor technical limitations of the commercial software are overcome.
