A reference system is used to translate pixels to real world dimensions. All
Scorpion image analysis tools have a reference as input. The tool will the
then position itself based on the reference.
A reference may be a tool,
e.g. a point or based on a point and a line, an edge of an object in the image.
References in Scorpion can handle translation, rotation, scaling and perspective.
Any number of references may be defined and combined in
Scorpion.
In robot guiding the robot calibration is normally performed by
ExternalReference, which provides a standard four point calibration.
The Calibrator tool handles lens distortion, lens magnification and
camera magnification using a Nth order nonlinear calibration based on a
precision grid.
