The target-actual comparison results from the superimposition of the measured volume model or surface model and the CAD dataset from your design department. The model obtained from the test piece is superimposed on the CAD model by means of a specific alignment logic. In the second step, the deviation between the model obtained and the CAD specification is calculated and displayed via a false-colour model of the test piece. The colours represent a certain deviation on the basis of a freely selectable scale.
What is particularly significant is that such a fast and straightforward analysis allows information to be obtained on the complete geometry of the test piece and not just on individual points.
