Abstract: We describe a real-time facade tracking system that uses, as setup information, only two images of a facade,\ncaptured on the moment. No more previous information is needed, such as a facade 3D model, dimensions or\naspect ratio. Feature points and their local descriptors are extracted from that pair of images and used during the\ndetection and tracking of the facade. Additionally, parallax and topological information is also used in order to\nincrease the overall robustness of the tracking process. Experiments show that the system can detect and track a\nwide variety of facades, including those that are not entirely planar, partially occluded or have few distinguishable\nvisual landmarks. The reliance on on-the-spot information, alone, makes this system useful for Outdoor\nAugmented Reality applications, in an Anywhere Augmentation urban context.
