Abstract
Systems and techniques for reconstructing one or more surfaces of an object including one or more opaque surfaces behind one or more refractive surfaces are provided. The systems and techniques may include obtaining one or more images of the object including an opaque surface located behind a refractive surface and determining one or more refractive surface constraints using the one or more images. The one or more refractive surface constraints constrain one or more characteristics of the refractive surface. The systems and techniques may further include reconstructing an opaque surface representation or a refractive surface representation using the one or more refractive surface constraints, the opaque surface representation representing the opaque surface of the object, and the refractive surface representation representing the refractive surface of the object.
