assumption that the rays refract only twice when traveling through the object (只发生了二次折射)

Consistency between 3D positions of surface points and normal
This paper presents a new refraction-based approach for reconstructing homogeneous transparent objects, through which light is redirected twice.(提出了一种基于折射的方法进行重建透明物体，其中光线只进行二次重定向) By introducing a novel position-normal consistency constraint,an optimization procedure is designed, which jointly reconstructs the 3D positions and normals at two refraction locations.(引入位置法线一致性约束，重建折射位置处3D位置和线) The refractive index of the object can also be reliably estimated by minimizing a new reconstruction error metric.(物体的折射率可以被最小化重建误差而估计)
