Claim One:
1. A method for representing objects tracked within two-dimensional video data by three-dimensional models, the method comprising: detecting and tracking movement of an object within a field of view environment of a two-dimensional data feed of a calibrated video camera, wherein the camera is calibrated to place the camera within a spatial height, orientation and position context of a three-dimensional model of the environment of the camera field of view; localizing a centroid of the tracked object; determining an intersection of the centroid with a ground-plane within the field of view environment; initializing a three-dimensional mesh-based volumetric model appropriate for the tracked object within the spatial context of the three-dimensional model of the environment by using a back-projection of a corresponding two-dimensional image of the tracked object as a function of the centroid and determined ground-plane intersection; projecting a texture of the two-dimensional object onto the three-dimensional model; and upgrading two-dimensional tracks of the object to three-dimensional motion to drive the three-dimensional mesh-based volumetric model.
