本文主要研究内容
作者王振武(2019)在《透玻透膜偏振成像方法研究》一文中研究指出:透玻透膜成像技术在民用卡口登记、交通监控肇事人员、公安追踪逃犯和军事反恐行动等领域有广泛的应用需求,但是因为贴膜玻璃的影响,普通监控设备无法实现透视监控。为实现对贴膜玻璃的透视监控,本文首先根据光线的传输过程建立了透玻透膜偏振成像模型,提出一种利用正交偏振信息的透玻透膜偏振成像方法,然后根据反射光的成像过程,提出一种基于分离反射的透玻透膜成像方法。分别开展模拟实验和室外实测实验,实验结果表明,所提方法能对透玻透膜成像质量有明显改善,具有一定的应用前景。本文的主要研究内容如下:(1)研究薄膜反射光和折射光的偏振特性,分析薄膜的光谱特性。研究光线在薄膜介质分界面处反射和折射时偏振特性的变化规律,测量薄膜的透过率光谱曲线分析薄膜的光谱特性,并分析普通相机难以透视贴膜玻璃的原因。(2)建立透玻透膜偏振成像模型,提出一种利用正交偏振信息的透玻透膜成像方法。根据光线的传输过程建立了透玻透膜偏振成像模型,结合光学调制传递函数特点表征出玻璃和薄膜的传输特性,实现对玻璃和薄膜透射率的估计,并根据目标光和环境光偏振信息的差异,利用目标光和环境光的正交偏振分量实现透玻透膜图像的信息重构。(3)建立透玻透膜反射成像模型,提出一种基于分离反射的透玻透膜偏振成像方法。根据光线在双表面介质处反射和折射的物理过程,建立基于物理层次的反射光成像模型,然后利用反射层和透射层场景信息的互斥性,通过求解出使背景层和反射层互信息最小的入射角度值,进而分离出反射层并保留背景层信息,实现基于分离反射光的透玻透膜成像。(4)针对透玻透膜成像需求,开展室内和室外实验,对两种方法所得的实验结果进行分析,并将两种方法所得结果进行对比。实验结果表明所提算法能有效重构出目标信息,提升了图像中目标的对比度,有效改善了透玻透膜成像质量。
