Abstract
A method of calibrating a vision based robotic system. The method includes engaging a calibration pin with a robotic tool and moving the calibration pin to a calibration block that includes at least one set of optical sensors having an optical transmitter to transmit an optical beam and an optical receiver to receive the optical beam. Further, the transmitted optical beam includes a center point. The method further includes: moving the calibration pin to the center point of the transmitted optical beam; determining a calibration pin center position relative to the robotic tool; and commanding a machine vision assembly having a camera to capture an image of a plurality of camera reading points of the calibration block and to determine a camera center position.
