擴增實境定位技術應用於建築與城市戶外導覽之研究-以“古蹟導覽系統”與“隱形招牌”應用爲例

The Research of Augmented Reality Registration Technology Applying on Architecture and Urban Outdoor Guiding Systems-Using "Cultural Heritage Guiding System" and "Invisible Shop Signboard" as Examples

摘要


擴增實(Augmented Reality, AR)技術應用於建築與城市戶外導覽的研究普遍受到各國的重視,然而相關案例最終落實於真實環境中的比例極少,形成一種特殊的現象。經過分析之後發現,此一現象的主要原因在於擴增實境的戶外定位技術遭遇瓶頸。現今主要採用的兩種定位技術當中,「儀器辨識定位法」的成本高而精度低,而「影像辨識定位法」的圖形條碼則對於視覺環境衝擊過大。有鑑於此,本研究針對上述問題,開發出兩套建築與城市戶外AR導覽技術,並且以「古蹟導覽系統」與「隱形招牌」爲例進行實測。經視覺衝擊評估(Visual Impact Assessment)後證實,本研究所開發之技術在建築與城市戶外導覽上,除了定位精確快速、系統成本低之外,更具有視覺環境衝擊輕之較佳效果。

並列摘要


Many countries have focused on the researches of augmented reality (AR) technology applying in urban and outdoor architecture guiding systems. However, only few of these researches are practicable in real outdoor environment. After analyses, we found that this situation is due to the obstacles of developing the outdoor registration technique in AR systems. Nowadays there are two major registration techniques called ”instrument registration technique” and ”image registration technique”. However the first technique is in high cost and low accuracy, while the later using registration pattern causes huge visual impacts in visual environment. Therefore, this research develops two AR outdoor guiding systems to overcome these obstacles, and uses ”Cultural heritage guiding system” and ”Invisible shop signboard” as demonstration examples. After assessments, it is approved that the techniques we created are not only with accurate image registration ability and low cost feature, but also with negligible visual impact for visual environment.
