1. A system for providing absolute orientation estimation of an object viewed by at least one camera in a space, the system comprising: a. one or more cameras, each having a known camera orientation with respect to the space; b. at least one detection component for detecting the object within one or more camera images and for providing object image location information; c. at least one relative orientation estimation component for estimating the relative orientation of said object within each camera image using the object image location information; and d. at least one absolute orientation estimation component for integrating the object image location information and the relative orientation estimate to produce an absolute orientation estimate.
