determining an upper-view datum plane which passes through the upper-view critical line and is perpendicular to the front-view datum plane according to the upper-view critical line, and determining a lower-view datum plane which passes through the lower-view critical line and is perpendicular to the front-view datum plane according to the lower-view critical line;
and determining a back-view reference plane which is parallel to the front-view reference plane and is respectively vertical to the left-view reference plane and the upper-view reference plane to obtain the skull six-view reference plane.
8. The method for acquiring skull correction information according to claim 5, further comprising a data fusion step comprising:
and carrying out data fusion on a skull six-view reference plane obtained by the first skull three-dimensional model and a skull six-view reference plane obtained by the second skull three-dimensional model to obtain a third skull three-dimensional model, wherein the first skull three-dimensional model is obtained by spiral CT, and the second skull three-dimensional model is obtained by nuclear magnetic resonance.
