Abstract

A stereo-camera head is provided, particularly for robotic applications, in which the parameters of focus, zoom and camera convergence are adjusted by remotely controlled motor drives. Camera separation distance and iris function can be similarly controlled. Twin cameras can be mounted on a common base by means of camera cradles pivotally mounted on the base or by means of rotary carriers that are mounted to traverse along respective lead screws driven by respective stepper motors. Alternatively, there may be a single camera lens system transmitting both left and right images received from left and right movable optical elements via a beam splitter/combiner. Two CCD imaging chips can receive the left and right images from the single lens system via a second beam splitter/combiner. A controlling micro-computer can be employed to keep the stereo images within human tolerance of fusion limits.
