The invention discloses a target motion estimation method in a scattering medium. The method comprises the following steps: acquiring a polarization image of a target object in the scattering medium; performing median filtering and Gaussian filtering on the polarization image to obtain a polarization filtering image; calculating an optical flow field of the target object based on the adjacent frames of polarization filtering images; an estimated displacement of the target is calculated based on the polarized light flow field. According to the scheme, the robustness and noise immunity of target motion estimation can be improved, and the accuracy of target motion estimation in the scattering medium is improved. 本发明公开了一种散射介质中目标运动估计方法，包括：获取目标物体在散射介质中的偏振图像；对偏振图像进行中值滤波和高斯滤波，得到偏振滤波图像；基于相邻帧偏振滤波图像计算目标物体的光流场；基于偏振光流场计算目标的估计位移。本方案能够提高目标运动估计的鲁棒性和抗噪性，提高散射介质中目标运动估计的准确性。
