A camera tracking system determines the three dimensional (3D) location and orientation of the film plane of a camera providing live recording of a subject, thereby defining a 3D coordinate system of the live action scene into which animated objects or characters may be automatically mapped with proper scale and 3D visual object by a computer animation system.

[ I claim:] [1.] Apparatus for providing, to user animation equipment, the three dimensional coordinate data identifying the location and orientation of the image plane of a recording camera which is visually recording subjects on a three dimensional film stage, comprising:a target assembly, having a plurality of light reflective markers disposed in a geometric pattern thereon, said pattern including a target plane, said target assembly being adapted for mounting to the recording camera in a manner such as to position said target plane parallel to the film plane of the recording camera;a motion capture system, having a plurality of viewer cameras and associated video processors, for recording the spatial location and orientation of said target assembly markers in each of a plurality of successive sample intervals with each of said plurality of viewer cameras; and for providing at an output thereof said recorded location and orientation as a two dimensional data set from each of said plurality of associated video processor in each said sample interval; andsignal processing means, responsive to each said two dimensional data set from each said associated video processor in each said sample interval, for reviewing at least two of said two dimensional data sets in each said sample interval and for reconstructing therefrom a result set of three dimensional coordinate data for each said sample interval, each said three dimensional data set being indicative of the location and orientation of the film plane of the recording camera in its related sample interval.
