摘要
偏振红外成像是红外成像技术的一个发展方向。偏振红外成像是利用红外光线的偏振态进行的"偏振梯度"成像和"偏振滤波"成像。从理论上说,即使两物点之间没有温差,只要存在着一定的偏振梯度,也能够清晰地成像,即偏振成像不但有普通红外成像的特点,还具有矢量成像的优势。换句话说,偏振红外成像和传统红外成像是兼容的。笔者的研究工作集中于同一景物的不同偏振态红外图像的融合。根据图像融合的一般原则,针对偏振红外图像的特性,提出了在像素层的一种融合算法。经过仿真表明该方式有一定的效果。通过融合增强了红外图像的图像效果。
Polarization infrared image is the developing orientation of infrared image technology.It is the 'polarizing gradient' image which use the infrared polarization.In theory,'Polarizing filter' image is that although there is no temperature difference between the two objects,it can take the image clearly only it exists definite polarization gradient.Polarization infrared image can take the image clearly not only when it has temperature difference but also in the low temperature conditions.That is,Polarizing image not only has the feature of normal infrared image,but also has the superiority of vector image.In another words,polarization infrared image and traditional infrared image is compatible.For instance,polarization infrared image can provide the message about objects target,differentiate flat metals board and cylinder,and differentiate the tank and heating flat board.All is set up on the basis of different polarizing signal.Obviously,polarizing image may take the relative cool objects.Our research focus on the mix of infrared image between different polarization in the same scenery.According to the principle of image mix and in light of the feature of the polarization infrared image.Through emulator,it indicates the way has definite effects.It enhance the image effects of the infrared image.
