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.
