偏振遥感图像特性表征及分析

Characterization and Analysis of the Polarization Images in Remote Sensing

本文基于实验型偏振CCD相机,在自然光照条件下,进行了自然目标和人工目标的偏振图像数据获取实验、结果显示:偏振图像信息与强度图像相比,低照度（阴影等）部分,特别是边缘信息得到了增强。从模拟目标样品的实验结果看,偏振信息对纹理探测效果十分明显,结合边缘信息的增强作用,偏振探测在军事侦察及伪装检测等方面有着广阔的应用前景。

This article is based on a experimental polarization CCD camera. In the sunlight, we obtain some polarization images of natural objects and manmade objects. As a result, compared with intensity images, low illuminance (shadow etc.), esperially information of edge is enhanced. The experimental results show that it is useful to detect texture by polarization information. Combined with the enhancement of edges' information , polarization detecting has wide application in military detecting and camouflage recogonision.
