擴增實境(augmented reality; AR)是從虛擬實境(virtual reality; VR)延伸的技術，主要是在現實環境中結合了三維虛擬物件，其特色為擁有高真實性、高互動性和高教育性等，現在已逐漸的在各個領域裡有許多廣泛的應用。在本篇論文中，我們設計了一個使用擴增實境與IPV6技術的網路對戰系統，利用我們所提出的基於邊緣偵測的即時視覺追蹤技術，以一般的USB攝影機作為視覺感測元件，並使用具有特定圖案的自訂標籤來標記三維虛擬物件。我們在來源影像中利用邊緣和骨架方向來對四邊形做偵測，再利用所找出的四邊形頂點對其做正規化，來進行標籤辨識，並且進一步的利用這些頂點來估算真實世界中，標籤與攝影機之間的空間關係。我們所提出的方法最終能使電腦在攝影機的畫面中感知多個標籤並加以辨識該身分，進而將各個三維虛擬物件合成於畫面中特定的位置，且結合新一代網路通訊協定(IPV6)，利用Streaming技術傳輸其動作與音效，保證遊戲品質與畫面流暢性，提供玩家高品質連線對戰的樂趣。此外，在現有擴增實境網路對戰系統中多半沒有考慮實體層的拓樸架構(Physical Topology)與使用者位址，以至於造成頻寬的浪費以及延遲的增加。因此，本篇論文同時提出一個IPV6參考實體網路架構、使用者位址與貢獻度的即時串流系統架構，利用貢獻度分群與近距離供應的概念，有效降低延遲，提高使用者滿意度，並節省網路頻寬與伺服器負載，提升系統效益。

Augmented reality is an extended technology from virtual reality. It focuses on combining with the real world and three-dimensional virtual objects. Augmented reality has high reality, high interaction, high education, and the other characteristics. For now, it has a lot of wide applications in various fields gradually. In this thesis, we design a multiplayer online games system which uses the techniques of augmented reality and IPV6. By using our real-time visual tracking techniques based on edge detection and employing a common USB camera for capturing source images, we can make the three-dimensional virtual objects display on our defined marker that combined with the source images in camera’s scan. In the beginning, we use the edges and skeletons to detect the quadrangular markers from source images. And then, we normalize quadrangles by making use of those vertices of quadrangle we found before for marker recognized. We can estimate the spatial relations in real word between patterns and the camera further. Our proposed method enables computers to sense each marker whether exists in the sight of the camera, which identity the marker has, and what pose and position it is. With this information, computers can superimpose virtual objects on the specific markers respectively, so that users can interact with the virtual objects simultaneously by interacting with the markers. We also combined with a new generation of Internet protocol (IPV6), and using streaming technology to transfer actions and sound effects, which can ensure the quality of the game and screen fluency. So, we provide high-quality games for players.
