We explore the combination of Shape-from-Polarization constraints with photometric constraints (i.e. photo-polarimetric shape estimation) provided by one or two light sources. We propose several alternative differential constraints and show how to express them in a unified partial differential system which solves directly for surface height. Combinations of these constraints provide different practical advantages, as for example an albedo invariant height estimation. Numerical results on synthetic and real-world data confirm the effectiveness of our proposed method.
