3D facial reconstruction of based on OpenCV and DirectX

Face as a biometric identification in computer vision is an important medium, in areas such as video surveillance, animation games, security anti-terrorist has a very wide range of applications, creating vivid, strong visibility of 3d face model, now has become a challenging in the field of computer vision is one of the important topics. At first, this paper used the zhongxing-micro ZC301P cameras to build a binocular stereo vision system for recording images. After the camera calibration and binocular calibration, the three-dimensional data of facial images were extracted using the functions of OpenCV computer vision library, and then 3d face model were reconstructed preliminary by DirectX. According the reconstruction process, the human face three-dimensional reconstruction software was designed and developed. The paper laid the foundation for the next step work that is to obtain more clear and strong visibility of 3d face.
