“…As depth increases, multi-path scattering destroys the pattern coming from the sky and only in-water scattering, produced near the observer, remains. At very low depth, the influence of wavy water surfaces on the polarization pattern has been simulated and measured [ 264 ]. It was revealed that the wind speed also has an influence on the pattern.…”

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.

“…In recent years, domestic scholars have also started to investigate underwater polarized light. in 2017, Zhou [21] In 2020, Cheng [22] et al also combined the Monte Carlo numerical simulation approach with the Mie scattering theory to simulate the multiple scattering of suspended particles underwater and modelled the polarization distribution in turbid water within the Snell window. The maximum depth at which the polarization distribution pattern can be stably kept under distinct types of water quality is also calculated, and the effects of turbidity, wavelength, type of suspended matter and particle size on the underwater polarization distribution pattern are discussed.…”

Bionic polarized light navigation technology is an emerging autonomous navigation technology with the advantages of full autonomy, anti-interference, and non-accumulation of errors. This paper reviews the research progress of bionic polarized light navigation technology from three aspects: research on sky light polarization distribution patterns, polarized light navigation sensor technology and combined navigation methods. This paper firstly compares the research progress on the sky polarization pattern in recent years, and introduces the atmospheric polarization pattern analysis model and underwater polarization pattern analysis model; reviews the research status of polarized light navigation sensors at home and abroad in recent years, and divides the sampling mechanism of sensors into point-source and imaging polarized navigation sensors and introduces them respectively; the current development of polarization sensors towards miniaturization and integration makes it possible to integrate polarization sensors with other navigation systems, and a combined navigation method with polarized light navigation sensors is introduced. Finally, the development trend of bionic polarized light navigation technology based on the polarization distribution characteristics of sky light is discussed, and the key issues to be solved in the development of navigation technology are presented.

“…Sabbah et al [5] considered the water interface refraction to simulate the underwater polarization pattern based on the Mueller matrix and Stokes vector. Some researchers discussed the effect of wavy water surface [10], water molecules [11], suspended particles [12], and other various factors [13] on the underwater polarization patterns. You et al [14] developed a hybrid of the matrix operator and Monte Carlo radiative transfer models to predict the polarized light field.…”

The feasibility of underwater polarization navigation technology in low visibility waters, especially in large depths, has always been questioned. To explore the influence of depth on underwater polarization navigation technology, we study the ocean polarized light fields at different depths. In this paper, we first establish the model of the coupled atmosphere-surface-underwater optical transmission, which can simulate the underwater polarization patterns at different depths. Then underwater detection equipment with ROV and polarization camera is constructed and we use it for underwater experiments. Finally, we research the effects of other environmental factors through experiment and simulation. Our study provides theoretical references for the application of underwater polarization navigation. Based on previous research work, this paper builds a relatively complete underwater polarization transmission model, which improves the polarization transmission theory. Underwater experiment results further prove the feasibility of underwater polarization navigation technology at deep depths. Due to the robustness of polarized light, polarization navigation technology also has great application potential in low visibility underwater.INDEX TERMS Ocean polarized light field, underwater depth, polarization navigation, Monte-Carlo method
