First Claim
Patent Images
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.

Abstract
A system and method to estimate the absolute coarse pose of a rigid body, and more specifically of an individual'"'"'s head as captured by overhead wide-angle cameras, by integrating position and pose information. Position information ideally includes three-dimensional position information provided by range finders or derived from images captured by multiple cameras. The three-dimensional position information can additionally be employed to determine the anchored viewing ray for the object.
