摘　　要：为了实现透过玻璃和薄膜对目标进行偏振成像,根据光线的物理传输过程建立了偏振透玻透膜成像模型,结合光学调制传递函数特点表征出玻璃和薄膜的传输系数。利用目标光和环境光的正交偏振分量提出一种偏振透玻透膜图像信息重构方法,分别采用曲线拟合、偏振滤波和频率域迭代算法实现重构算法中参数的估计,重构出透玻透膜图像。开展了室内模拟条件和室外实测环境下的实验,结果表明该方法能有效重构出透玻透膜图像中的人员、景物等目标信息。In order to realize polarization imaging of the target penetrating glass and film,the polarized imaging model of penetrating glass and film is established according to the physical transmission process of light.The transmission coefficient of glass and film is estimated combining with the characteristics of optical modulation transfer function.An information reconstruction method of image of penetrating glass and film is put forward by using the orthogonal polarization components of the target light and ambient light.The curve fitting method,polarization filtering and frequency domain iterative algorithms are used to estimate the parameters in the reconstruction algorithm,and finally the image of penetrating glass and film is reconstructed.The experiments are carried out in indoor simulation conditions and outdoor environment.Results show that the method can effectively reconstruct the target information of people and scenes in the image of penetrating the glass and film.
