摘要
彩色分焦平面偏振相机是一种新型偏振成像装置,能够同时获取目标0°,45°,90°和135°四个偏振方向的彩色三通道(RGB)强度信息,但需要解决分辨率损失和像元错位的问题。本文提出一种适用于分焦平面相机的彩色偏振图像配准方法。通过实验对所提配准方法进行验证,结果表明:所提配准方法能够降低像元错位问题对后续彩色偏振图像解析精度的影响。
The color division of focus plane polarization camera is a new type of polarization imaging system that can simultaneously obtain the color three-channel(RGB)intensity information of the four polarization directions of 0°,45°,90°and 135°,but the problem of resolution loss and pixel misalignment needs to be solved.In this paper,a registration method of color polarized images suitable for division of focal plane camera is proposed.The registration method is verified through experiments,and the results show that it can effectively reduce the effect of pixel misalignment on the resolution accuracy of color polarization images.
