CONTROL APPARATUS, ROBOT AND ROBOT SYSTEM
A control apparatus, a robot and a robot system to which settings for calibration can be easily and appropriately made are to be provided.
A control apparatus that can control driving of a robot, an imaging unit and a display unit based on input of an input unit, includes a display control unit that allows the display unit to display an input window for inputting a robot as an object to be controlled, and allows the display unit to display an imaging unit input part that guides input of an attachment position of the imaging unit corresponding to the input robot, and a calibration control unit that performs a calibration of correlating a coordinate system of the robot and a coordinate system of the imaging unit based on the input attachment position of the imaging unit.
CONTROL DEVICE, ROBOT, AND ROBOT SYSTEM
A control device, which controls a robot having a movable unit including a plurality of arms, includes a processor that performs calibration between a coordinate system of an imaging unit disposed in an arm different from an arm positioned on a most distal side of the movable unit and a coordinate system of the robot. The processor performs the calibration, based on a captured image obtained by causing the imaging unit to image a marker.
Simultaneous Kinematic and Hand-Eye Calibration
Described are machine vision systems and methods for simultaneous kinematic and hand-eye calibration. A machine vision system includes a robot or motion stage and a camera in communication with a control system. The control system is configured to move the robot or motion stage to poses, and for each pose: capture an image of calibration target features and robot joint angles or motion stage encoder counts. The control system is configured to obtain initial values for robot or motion stage calibration parameters, and determine initial values for hand-eye calibration parameters based on the initial values for the robot or motion stage calibration parameters, the image, and joint angles or encoder counts. The control system is configured to determine final values for the hand-eye calibration parameters and robot or motion stage calibration parameters by refining the hand-eye calibration parameters and robot or motion stage calibration parameters to minimize a cost function.
