Calibration

Calibration

Calibration is used to correctly position a workpiece or a resource, e.g. a fixture, in the virtual workcell.

There are two calibration methods available:

	3 Point calibration Position adjustment measured from 3 pairs of calibration points. Typically being applied to position workpieces on a fixture or to position other devices that usually have fixed measurable reference positions to place and align the component.
	Linear least square calibration Position adjustment measured from n pairs of calibration points by minimizing the sums of the squares of deviation between the measured and expected values. Typically being applied on resources, or workpieces, that have clear reachable and defined points or edges on the real and virtual component, that can be picked and measured.
	Multi point calibration Position adjustment measured from multiple points on the surface of the workpiece or resource. Typically being applied on workpieces of which the real shape has a degree of deformation compared to its original digital shape and that have no clear defined positions that can be picked to measure.
