We developed a system that can easily and efficiently reconstruct 3D faces. The system takes a video sequence of the face having a pan rotation from one single regular camera. Based on the corresponding points tracked by optical flow, we can reconstruct the 3D face using the factorization approach in an orthogonal projection model. Then we improve the orthogonal model to approximate the perspective model to get a more reliable result. The proposed system also solves the missing point problem. Finally our smoothing method can make the 3D face look smoother and more realistic by interpolating additional vertices.
