摘要

近年來，諸多研究表明結合擴增實境技術(AR)與建築資訊模型(BIM)能對施工方面帶來許多好處，如提高施工的安全性，降低返工之施工勞動成本和應用模型可視化來實施工程進度之監控。因此，許多研究致力於將AR應用於工程領域中。然而，應用AR於工程進度監控方面的實施仍然遇到許多挑戰，像是AR之開發、研究、設備花費成本過高，複雜且不完整的BIM到AR所需模型之模型轉換過程，以及施工現場與BIM模型資訊的不對等。為了對這方面進行貢獻，本研究注重於定義關於應用AR於工程監控作業的BIM模型需求，且針對AR日常監控作業來開發一個更加方便的模型轉換流程。本研究所提出之方法包括三個步驟：(1) AR監控作業之模型要求，(2) 模型準備流程(3) 現場實驗驗證。首先，第一步先針對相關文獻進行討論，並參考相關文獻之模型訊息來定義AR應用於施工監測作業時之BIM模型需求。接下來第二步提出一個模型轉換流程來將BIM模型轉換到AR設備HoloLens中使用之模型，並通過對工程之施作系統、排程、與工作區域進行討論分析。通過這項模型轉換流程，BIM模型已經可以成功轉換到AR所需之模型中並進行有效的可視化應用。最後，該研究成果成功通過兩個案例之研究以及工程專業人員的深入訪談中得到有效之驗證。

Recent research has focused on applying Augmented Reality (AR) technology in the architecture, engineering, and construction (AEC) industry. Research shows that Building Information Modeling (BIM) with AR can bring several benefits, such as improving safety, lowering labor costs, and enhancing visualization. However, it is still challenging for AR implementation because of the high investment in research and development of AR-oriented processes, high cost of tools and AR devices, incomplete and complicated BIM to AR process, and inadequate connection between on-site and BIM information. In order to contribute to the body of knowledge, this research focuses on defining BIM requirements that may support effective monitoring activities with AR. Additionally, a workflow that enables a practical process for AR-based daily construction monitoring tasks is introduced. In this research, the proposed method includes three steps: (1) AR tasks model requirements, (2) model preparation, and (3) on-site experiments. At first, it is essential to do a literature review to define the BIM model requirements for AR construction monitoring tasks. After that, we presented a BIM-to-AR workflow to transfer the BIM model to an AR-ready model for HoloLens by building's working system, schedule, and work area. This workflow facilitates the BIM conversion process and successfully efficiently visualizes the model. In the end, the result has been validated through two case studies and in-depth interviews with construction practitioners.
