Visual sensor system for producing stereoscopic visual information

摘要

A visual sensor system for producing stereoscopic visual information comprises two sensors arranged on a plane and spaced by a predetermined distance from each other, light emitting elements arranged in one of the sensors for emitting light to an object through an imaging lens of the one sensor, a photo-sensor arranged on the other sensor for sensing the light reflected by the object through an imaging lens of the other sensor and determining a convergence position of the object based on an incident position of the sensed light, a changing device for changing a convergence angle between the two sensor on the focusing plane by relatively changing the direction of the other sensor, and a controller for controlling the changing device to change the direction of the other sensor toward the convergence position of the object.
