1. A measurement method for determining an ACTUAL position (5?) of an omega profile component (2) relative to a shell component (1), the method comprising:

optically acquiring, via a measuring unit, in a contactless manner, a profile cross section of the omega profile component

(2), the measuring unit frontally acquiring the profile cross section, the omega profile component (2) being placed on the shell component in the ACTUAL position;

establishing, by an evaluating unit (4) coupled to said measuring unit (3), a plurality of adjacently spaced apart measuring points (6, 6?) at first and second mutually opposing flank sides (7a, 7a?, 7b, 7b?) of the profile cross section of the omega profile component (2);

extending, via the evaluating unit (4), a first regression line (8a, 8a?), through the measuring points (6, 6?) on the first flank side (7a, 7a?);

extending, via the evaluating unit (4), a second regression line (8b, 8b?) through the measuring points (6, 6?) on the second flank side (7b, 7b?);

determining, via the evaluating unit (4), the point of intersection (9, 9?) of the first regression line (8a, 8a?) and the second regression line (8b, 8b?); and

determining, via the evaluating unit (4), the ACTUAL position (5?) of the omega profile component (2) relative to the shell component (1) from the point of intersection (9, 9?).
