ABSTRACT:
An integrated controller for controlling both pan and vergent movements of a stereoscopic vision system, having two cameras, is described. The controller determines motion and direction based on a provided retinal error. Each of the cameras is moved until no retinal error remains which results from camera orientation. A butterfly controller accepts data input relating to retinal errors from any number of sources and provides a single signal relating to common motion and another signal relating to vergent motion to each control circuit. The circuits are designed to operate in common mode or differential mode thereby causing sensors to move in different directions when controlled by same control signals.
