1. A method of determining a relative position and orientation between a base camera and a non-base camera, comprising: measuring a path of a moving object with the base camera in a base coordinate frame; measuring the object path with the non-base camera in a non-base coordinate frame; calculating transformation parameters based on the object path; and applying the transformation parameters to the object path measured by the non-base camera such that that the object path measured by the non-base camera may be expressed in the base coordinate frame.
