A case study: Mobile augmented reality system for visualization of large buildings

CE consumer devices are becoming powerful enough to realize augmented reality (AR) systems on mobile devices, and to visualize complex virtual scenes. This is not limited to CE and increasingly demanded for professional applications. One of them is to visualize power transmission lines and their impact on the landscape. This might help discuss diverse opinions and to optimize the planning in various directions. We propose a mobile augmented reality system by utilizing a consumer Tablet-PC. A main task of AR is camera-pose estimation which can be computational intensive. For that reason we decided to use a marker-based approach with four color spheres.
