在建築物的施工或維護階段，如使用者需在現地檢視BIM，傳統的方式是於攜帶至現場的平板電腦或筆記型電腦上的BIM Viewer軟體上呈現，而欲透過BIM Viewer檢視現地中的某個建築元件，需先以手動方式尋找該元件的所在位置，選取其元件才能檢視其相關資訊與參數，此種方式不但需要手動的模型檢視操作操作，才能將資訊即時回饋給使用者，而且透過電腦觀看模型無法與現地真實所見情景結合，在畫面上無法同步。本研究提出擴增實境整合室內定位技術之BIM資訊現地呈現模式，其整合擴增實境與室內定位的技術，讓所建立包含建物元件屬性參數之BIM，可和現地影像疊加，直接呈現在現地中，其是以3D模型呈現BIM模型元件，輔以文字顯示BIM元件之屬性參數，透過擴增實境設備疊加顯示於建築元件上，即時回饋給使用者，建築物內需建置無線網路環境，且每一個房間是使用一組相同的Marker，貼於該空間中的各建築元件上，系統先透過無線AP進行室內定位，辨識出使用者所在之空間，再配合Marker做該空間中建築元件的辨識，即可基於所辨識出建築元件從雲端BIM資料庫中存取該元件的3D模型與相關屬性參數，疊加顯示於該建築元件上。本研究以WorldViz Vizard平台為開發環境，Vuzix頭戴式液晶顯示器(HMD)為擴增實境之顯示設備，基於所提模式開發了原型系統，其可讓使用者透過HMD即時檢視與現地所見建築元件相對應的BIM元件與相關參數，不需手動的模型檢視操作操作，即達成虛擬的BIM元件與現地所見情景間的虛實整合。

This study applied and integrated Augmented Reality (AR) and indoor positioning technologies to develop an in-site viewing model of BIM. In the proposed model, BIM information are displayed and superimposed on real building elements in 3D component models or surrounding texts using AR technology. The building must have wireless network environment inside, and each room use the same set of markers to markup on the building elements in the room. The system use wireless access point for indoor positioning to identify the user’s location in room, and then use markers to identify the building elements in the room. Once a building element is identified, the system retrieves the 3D model or property information from a Cloud-based BIM database and then superimposes them on the view of real building element. A prototype system was developed based on the proposed model using WorldViz Vizard platform. The proposed system achieves the integrated display of virtual BIM and real in-site scene in HMD without manual navigation for model viewing.
