The forming analysis system compares the 3D positions of measuring points in a flat and in a deformed state.
For the automatic spatial orientation of the individual images or views, coded points are position close to or on the measuring object.
Therefore, by means of images made from other angles of view, it is possible to calculate the camera location using this point relation.
During the acquisition of an image set it is the goal to record points from multiple different directions that show the largest possible angles (A, B, C) to each other.
As a default, Forming analysis system presumes an exactly regular initial pattern which is on one plane and for which the point distance is known.
The full-field color representation of the strain results from the 3D positions of these grid line intersection points.
