The invention aims at a method for creating a real-time realistic- looking image of a pair of virtual glasses positioned on a real user face image issued from a single image, a bundle of pictures, a video clip or a real-time camera stream, characterized in that it comprises the following steps: 100. A face analysis process to estimate the 3D rotation matrix, the 3D translation vector, morphology parameters of the user's face; 200. A glasses positioning process associated with a try-on mode for look or real-size simulation that estimate the 3D rotation matrix, the 3D translation vector, and global and local deformation parameters of the virtual glasses, and arms articulation, adapted to the morphology parameters computed in step 100; 400. A realistic rendering process to mix the real user face image with the virtual glasses positioned in step 200. 本发明旨在提供种用于创建位于个真实用户脸部图像上的副虚拟眼镜的实时逼真图像的方法，所述真实用户脸部图像来自单个图像、组图片、视频剪辑或实时相机视频流，该方法特征在于包括以下步骤：-100、个人脸分析过程，该过程用于估计用户脸部的3D旋转矩阵、3D平移矢量和形态参数；-200、个眼镜定位过程，该过程与用于外观或真实尺寸模拟的试戴模
