Corrective lenses introduce distortion caused by the refraction effect, which changes the wear's appearance. To give users a more realistic experience, a virtual try-on system for prescription eyeglasses modifies an input video and virtually inserts prescription eyeglasses, producing an output similar to a virtual mirror. The proposed system generates a 3D representation of the corrective lenses mounted into the eyeglasses frame and modifies the video sequence to virtually insert the eyeglasses through image-based rendering. Unlike existing virtual try-on systems, this approach simulates the refraction effects due to the corrective lens and takes into account reflections and shading.
矫正镜片会引入由折射效应引起的失真，这会改变佩戴者的外观。为了给用户提供更逼真的体验，一种用于处方眼镜的虚拟试戴系统会修改输入视频，并虚拟插入处方眼镜，生成类似于虚拟镜子的输出。所提出的系统生成安装在眼镜框架中的矫正镜片的3D表示，并通过基于图像的渲染修改视频序列以虚拟插入眼镜。与现有的虚拟试戴系统不同，这种方法模拟了矫正镜片的折射效应，并考虑了反射和阴影。
