Thanks to the augmented reality technology, virtual information can be embodied and integrated in the real world, enabling the increasingly wide applications of virtual information detached from the physical world in real-world scenarios. On this basis, this study proposes an efficient real-time virtual try-on technique that can be applied to a variety of practical scenarios. For example, in the e-commerce scenario, users can select the corresponding model file of a certain style online for virtual try-on before purchasing the product and make their decisions upon the virtual try-on results. The proposed method maps the model file to a graphical state that can be added with the real-time video stream on the basis of the face pose parameters. After the addition is performed in a specific region, the result is fed back to the video frame. The final added model file is able to adapt itself to the position change of the head. The experimental results show that the proposed method delivers a good performance in face distance and position, graphics rendering, and real-time wearability.
