This demonstration explains how the FANUC Robotics iRVision 3D vision system is calibrated. The first step is to teach a user frame to the calibration grid. One method to teach the user frame is with a pointer tool; a new method is to use the camera moving it over the calibration grid and taking pictures of the grid. Note: The Calibration Grid user frame can be taught before the camera is calibrated by using a feature called visual TCP (Tool Center Point). Now that the robot knows where (in ...
