Abstract
A system and method of generating a virtual view of a scene captured by a network of cameras. The method comprises simultaneously capturing images of the scene using a plurality of cameras of the network; determining, using the captured images, a model of atmospheric conditions in the scene; and defining a virtual camera relative to the scene. The method further comprises rendering the scene from a viewpoint of the virtual camera by adjusting pixels of the captured images corresponding to the viewpoint, the adjusting based on a three-dimensional model of the scene, locations of the plurality of cameras relative to the scene, the viewpoint of the virtual camera, and the geometric model of atmospheric conditions.
