Abstract: In order to polarization imaging of the target penetrating the glass and film, the polarized images model of targets penetrating the glass and film is firstly established according to the physical transmission process of light. The transmission coefficient of glass and film is estimated by the characteristics of optical modulation transfer function in the model. Secondly, the information reconstruction of the image penetrating the glass and film is realized by using the orthogonal polarization components of the target light and the ambient light. Then, the curve fitting method, the polarization filtering algorithm and the frequency domain iterative algorithm are used to estimate the parameters in the reconstruction algorithm, and finally the image of penetrating the glass and film reconstructed. Experiments were carried out in indoor simulation conditions and outdoor measured environments. The experimental results show that the method can effectively reconstruct the target information of people and scenes in the image of penetrating the glass and film.
