Abstract

In order to better characterize the polarization characteristics of reflected light in oil spill monitoring by remote sensing on the sea surface and improve the accuracy of oil spill detection, the quaternion method is introduced into the oil spill detection system, and a kind of oil spill monitoring technology based on quaternion is proposed in this paper. Firstly, the quaternion matrix method for calculating the sea surface reflection polarization information is proposed, and the relationship between the characteristic parameters of quaternion and the refractive index of oil film is discussed. Then， four kinds of oils crude oil, soybean oil, lubricating oil and diesel oil are used as the experimental samples for oily pollution on water surface, and the characteristic quaternion parameters, s and p components of different samples are obtained through the reflection images at different polarization directions, so the identification of different oil products is realized.. The experimental results show that the quaternion polarization characteristics can be used as an important parameter for oil identification.
