Patent ID: 8506182

Claim:
A stereographic camera system comprising: an upright support having a longitudinal axis; a camera support coupled to a first end of the upright support, the camera support mounting first and second cameras, the first camera being movable with respect to the second camera to set an interocular distance and a convergence angle between the first and second cameras; a ballast coupled to a second end of the upright support; a balance mechanism for moving a movable portion of the stereographic camera system relative to the upright support in response to movement of the first camera with respect to the second camera to maintain a constant weight distribution of the stereographic camera system; and a control system to control the balance mechanism using the following equation: Y=m 1 X 1 +m 2 X 2 +b, Where Y=a position of a balance motor that positions the movable portion, m 1 =a predetermined Convergence Factor, m 2 =a predetermined Interocular Factor, X 1 =a position of a convergence motor that sets the convergence angle, X 2 =a position of an interocular motor that sets the interocular distance, b=a predetermined Offset.
