Abstract


In order to solve the traditional gesture sensitive 2D image - based face recognition algorithm , the image of the face of a 3D face model synthesis specify attitude , so as to improve the performance of face recognition algorithm based on 2D image program . 3D face model reconstruction algorithm practical difference for the past , a high degree of complexity of the algorithm and noise-sensitive defect , the paper proposed a method using three different posture depth map obtained by stereo vision reconstruction of 3D face model . The method by hand to determine the combination of the computer correction feature points to the initial integration of the depth chart , then the use of improved ICP algorithm to get the final three-dimensional face model . 3D face model , combined with the Euclidean space rotation transformation and projection matrices generated face images under different poses . The experimental results show that the fusion of an average error of only 1.32 mm, the two - dimensional face image generated posture real .
