摘要： 为解决多路平行同时偏振成像系统由于光轴位置不同带来的成像偏差问题，设计了
一种多源图像融合的光学前端，对3 幅坐标不一的偏振图像进行实时配准研究。在平行光轴的基础
上，通过在系统结构内部安装光楔，计算不同视场图像的成像视差，求得三方向偏振图像各个像素
点对应的仿射变换需要的参数，并将其建立一套像素匹配存储表，通过直接查表的方式，调用仿射
地址和对应的权值完成三方向偏振图像的配准，最后利用配准后的图像求解出偏振度图像。实验结
果表明，该设计能够准确地实现三方向偏振图像的实时配准，避免了由于源图像的偏差产生的伪偏
振现象，使配准后合成的偏振图像能够准确的反映目标的偏振信息并且达到了实时配准的要求。

Abstract: In order to solve the problem of imaging deviation caused by the different position of optical
axis of multi channel parallel simultaneous polarization imaging system, a multi source image fusion
optical front-end is designed to research real time image registration of three different coordinates’
polarization images. First, we install a light wedge within the system structure based on the parallel
optical axis. Then we calculate the imaging parallax of different field image and obtain the parameters
of affine transformation that correspond with each pixel of three directions polarization image.
According to the parameters, a pixel matching table storage was established. At last we call affinity
address and the corresponding weights by looking-up the table directly to complete three directions
polarization image registration. Experimental results indicate that this design can accurately achieve the
three directions polarization image registration in real-time, it avoid pseudo polarization phenomenon
which caused by deviation of the source images. The polarization image which is obtained after
registration can accurately reflect the polarization information of objectives, and it can also register the
polarization images in real time.

Key words: polarization image, image registration, parallel optical axis, binocular parallax, affine
transformation
