GIS-based Augmented Reality: A realistic approach to environmental visualisation (Paperback)

The aim of the research presented in this book is to devise a photorealistic visualisation method, which uses off-line video-based augmented reality technique in an immersive environment. The application of such technique in simulating the dynamics of landscape changes could improve public communication and community awareness of environmental changes. The proposed technique makes a linkage between GIS modelling and realistic video frames. Combination of computer graphics and video footage is not new by itself but using GIS as reference, environmental changes may be augmented to video frames in their correct spatial position. Also, because of using the real texture, computer-generated objects could be well matched to background frames and look hardly detectable. Despite limited interactivity in comparison with fully interactive visualisation systems, because of its capabilities in realistic representation of environmental changes, the proposed system has the potential to improve the communication between policy makers and non-experts and to improve decision-making process.

本書所呈現的研究目標是開發一種逼真的視覺化方法，該方法利用離線視頻增強現實技術在沉浸式環境中進行。將這種技術應用於模擬景觀變化的動態可以提高公眾溝通和社區對環境變化的認識。所提出的技術將地理信息系統（GIS）建模與逼真的視頻幀相結合。雖然計算機圖形和視頻素材的結合本身並不新鮮，但通過使用GIS作為參考，環境變化可以在視頻幀中以正確的空間位置進行增強。此外，由於使用真實紋理，計算機生成的物體可以與背景幀完美匹配，幾乎不可檢測。儘管與完全互動的視覺化系統相比，互動性有限，但由於其能夠逼真地呈現環境變化，所提出的系統有潛力改善政策制定者與非專業人士之間的溝通，並改善決策過程。
