Joint interactive visualization of 3D models and pictures in walkable scenes

PhotoCloud is a real-time distributed system which allows an end-user to interactively explore and visualize large mixed datasets composed of (up to) several thousands of calibrated 2D photographs joint together with a high-complexity 3D description of the scene. The system is not tailored to any specific data acquisition process, but aims at generality and flexibility. One major focus in our design is scalability in terms of geometric complexity and number of photographs, tackled by means of multiresolution and dynamic hierarchical representation of the data.
