The Research Of3D Face Reconstruction Based On Geometric Transformation

In recent years, with the development of computer graphics,3D face in television, games, teaching, medical and other fields has wide applicati-on.3D face reconstruction has also become one of the current research focus; With these year’s development, re-searchers have put forward a lot good ways.Although there are many methods on3D face reconstruction, most of the current3D face modeling technology requires a complex and compute process, this paper puts an easier and more efficient way based on geometric transformation, includes the fol-lowing aspects.First of all, Proposed a new algorithm to generate a specific face mo-del. This algorithm is mainly about triangulation based on face feature points, then adjust the generic model based on Barycentric coordinates’ affine transformation invariance.Secondly, proposed a method about getting the front of the face feat-ure points information according to the symmetry of the human face if the face in the image has an angle.Finally, texture mapping with OpenGl technology, and the texture co-ordinates is also got with Barycentric coordinates’ affine transformation invariance.With the method proposed by this paper, in the platform of VS2010combination OpenGl technology,3D face reconstruction system is completed and get realistic3D face reconstruction.
