地理資訊系統整合擴增實境之區域導引系統

在本論文中，以智慧型行動裝置提供使用者園區個人導覽系統，一般的導覽系統大多運用全球定位系統 (Global Positioning System 簡稱 GPS) 與無線網路 (Wi-Fi) 輔助的 Assisted GPS (A-GPS)作為識別使用者位置的技術，然而若是需要在室內使用路線導覽的情形， GPS 類型的系統無法提供垂直位能差距等樓層資訊，使得其在應用場合上有所限制。因此在此篇論文中，提出一個以擴增實境(Augmented Reality)做為一個基礎的定位技術，讓使用者可以利用此方法在室內做為定位的基礎，再以 A star 演算法做最短路徑規劃建立導引地圖，讓使用者可以在不受限於室內/外的環境中獲得系統提供的導引路徑後順利在區域中的任兩點間進行移動。本文提出的技術非常適合應用於各種室內個人導覽系統，本文實現的系統不使用 GPS 或是 A-GPS 做定位辨識，省去手持行動裝置接收 GPS 訊號的耗能，替節省行動裝置耗能的前提下提供使用者導引所需的資訊提供了一個新的解決方法。

In this thesis, a personal park navigation system designed for the smart mobile device is presented for the users. In recent days, most of the navigation systems utilize Global Positioning System (GPS) and Wi-Fi assisted A-GPS as the tools for identifying the location of the user. However, this kind of navigation system cannot be used in the indoor environment because the GPS signal is blocked by the architecture. In addition, the vertical movement information such as the floor information is not available in the GPS. It implies that the ability of GPS is limited in the indoor situation. Therefore, in this thesis, a new navigation system is constructed of the iAugmented Reality (AR) and the A-star shortest path planning guide map. This system allows users to receive the navigation routing information no matter in the indoor or the outdoor environment. Users will easily be able to find the shortest path between two points in the system supported region. The proposed system is not constructed based on the positioning information from GPS or A-GPS, but the positioning information is generated by the AR code. Hence, the energy consumption of the mobile device is reduced because the energy for receiving the GPS/A-GPS signal and the Wi-Fi signal can be cut-off.
