A method of machine vision calibration is described for machine vision systems whose camera field of view resides in the working envelope of the manipulator. The resulting calibration technique is easy to use and adds no additional cost to the automation workcell. Machine vision applications in the past have typically been implemented as stand-alone devices. This required calibration fixtures to be made which were costly and prone to error if not used correctly. For industrial automation applications of machine vision, a high priority must be placed on ease of use and low cost. For robotic processes that use machine vision to determine position and orientation information, some form of calibration must be performed.
