Abstract

Cities are one of the most pertinent application spaces for current Augmented Reality systems but have proven to be technically challenging. They are abundant with information, while also requiring occlusion of that same information at different levels of depth. With more and more detailed 3D city models becoming available through the CityGML standard, we introduce an approach that can display contextual multimedia annotations on buildings in AR and properly occlude them without depending on complex computer vision analysis. Our approach also integrates directly with CityGML through an Application Domain Extension (ADE). We implement a prototype that allows for the dynamic textual labeling of urban environments on a variety of AR-capable smartphones using the Unity game engine.
