1. A method of mirrored scanning for determining deviation introduced into a panel during manufacturing, wherein the panel comprises an outer surface and an inner surface, the method comprising:
fixturing the panel by holding it at at least two locations via a fixture;
performing a first metrology scan on the outer surface of the panel, with respect to a reference frame, thereby producing a first 3D surface scan of the outer surface of the panel;
performing a second metrology scan on the inner surface of the panel, with respect to the reference frame, thereby producing a second 3D surface scan of the inner surface of the panel, wherein the inner surface is opposite the outer surface; and
determining an inner mold line (IML) surface relative to an outer mold line (OML) surface, using the first 3D surface scan and the second 3D surface scan, thereby characterizing tooling deviation of a tooling fixture used to form the panel.
