Apparatus for generating 3d volume mask model and method therefor

An apparatus for generating 3-dimensional (3D) volume mask data, comprising:

• a 2-dimensional (2D) mask data collector configured to generate 2D mask feature data, which contains feature points, by using contour data extracted from a 2D mask image, generate at least one group of triangles by using the 2D mask feature data and grouping every three proximal feature points, and generate a 2D mask mesh with the at least one group of triangles;
• a 3D mask model generator configured to calculate a vertex z-value in 3D space using X-Y coordinate values of a vertex of a 2D mask which are contained in the 2D mask mesh, and generate 3D mask model using the calculated vertex z-value;
• and
• a 3D mask model adjuster configured to modify the 3D mask model to be located in 3D space based on acquired 3D face scanning data, extract outer vertex data of the modified 3D mask model, and generate 3D volume mask model by connecting corresponding outer vertices and thereby creating volume for the 3D mask model.
