“…The moon’s polarization pattern can also be used for positioning at nighttime. Chen et al obtained a positioning error within tens of kilometers, yielding a latitude accuracy of 0.62° (1

) and a longitude accuracy of 0.02° (1

) [ 274 ]. Yet, how all light patterns properties (polarization information and intensity information) of the sun or the moon could be combined to obtain the best level of performance remains an open question.…”

This review article aims to address common research questions in passive polarized vision for robotics. What kind of polarization sensing can we embed into robots? Can we find our geolocation and true north heading by detecting light scattering from the sky as animals do? How should polarization images be related to the physical properties of reflecting surfaces in the context of scene understanding? This review article is divided into three main sections to address these questions, as well as to assist roboticists in identifying future directions in passive polarized vision for robotics. After an introduction, three key interconnected areas will be covered in the following sections: embedded polarization imaging; polarized vision for robotics navigation; and polarized vision for scene understanding. We will then discuss how polarized vision, a type of vision commonly used in the animal kingdom, should be implemented in robotics; this type of vision has not yet been exploited in robotics service. Passive polarized vision could be a supplemental perceptive modality of localization techniques to complement and reinforce more conventional ones.
