| Summary: | 碩士 === 國立臺灣科技大學 === 資訊工程系 === 100 === 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.
