Abstract
A method for constructing one or more 3D scene models comprising 3D objects and representing a scene, based upon a prior 3D scene model and a model of scene changes, is described. The method comprises the steps of acquiring an image of the scene; initializing the computed 3D scene model to the prior 3D scene model; and modifying the computed 3D scene model to be consistent with the image, possibly constructing and modifying alternative 3D scene models. In some embodiments, a single 3D scene model is chosen and is the result; in other embodiments, the result is a set of 3D scene models. In some embodiments, a set of possible prior scene models is considered.
