摘      要：Underwater target motion estimation is a challenge for ocean military and scientific *** this work,we propose a method based on the combination of polarization imaging and optical flow for turbid underwater target *** imaging can reduce the influence of backscattered light and obtain high-quality images *** optical flow shows the motion and structural information of the *** use polarized optical flow to obtain the optical flow field and estimate the target *** experimental results of different targets under varying water turbidity levels illustrate that our method is realizable and *** precision is verified by comparing the results with the precise displacement data and calculating two error *** proposed method based on polarized optical flow can obtain accurate displacement information and a good recognition *** target segmentation based on the Otsu method further proves the superiority of the polarized optical flow under turbid *** study is valuable for target detection and motion estimation in scattering environments.
