The Calibration Tool allows you to calibrate your imaging system using real world coordinates using sub-pixel accuracy. Once your system is calibrated you can obtain real world measurement data with sub-pixel accuracy using the other tools. The Calibration Tool makes it simple to manage and test your calibration objects. You can have multiple calibration objects open at once. This is needed if you are using a multiple camera setup. You calibrate the system using simple point & click operations. The calibration is a Full Projective Transformation. This means that the camera can be located anywhere with respect to your object, it does not have to be normal to the plane.
