This paper described a system that could be used to estimate 3D facial pose rapidly and accurately,and proposed a robust pose estimation method for 3D face models,which was based on facial reflective symmetry.With extended Gaussian image and smallest enclosing ball theories,the method detected the symmetry plane of 3D face at first,and searched the tip of nose,then estimated the pose approximately.In order to obtain more accurate result,the method corrected the approximate estimation in a given confine.The experiments using real face data obtained by 3D scanner,demonstrated the effectiveness as well as robustness.
