| Popis: | 99 This thesis presents stereo vision used to reconstruct a 3D face model. The main method uses the facial features to find the corresponding points in left and right images. The disparity relation of the corresponding left and right image points is used to calculate the face depth information. This information is used to reconstruct a three-dimensional face model. The feature point demarcation is based on principle component analysis (PCA) and active shape model (ASM) to complete face image segmentation and the corresponding points search. The general camera lens has radial distortion, which impacts the matching errors on the left and right images. The camera calibration method is used to calculate the internal and external camera parameters for image distortion correction. The left and right image disparity map is used with Matlab to draw a three-dimensional face model. The experimental results demonstrate the reconstructed 3D face model has good identification properties. |
