摘要
提出了一种基于偏振特征的目标识别技术。实验采用He-Ne激光作为照明光源,根据目标散射光偏振度的差异,利用DSP图像采集系统获取了目标的偏振图像,并利用图像融合技术计算了目标的Stokes图像和偏振度图像。结果显示:偏振成像有效地滤除了杂乱背景散射光的影响,明显提高了目标成像的对比度和分辨率。所以偏振成像技术可以有效地提高目标探测和识别效率。
A technique of target identification based on polarized characteristics is presented. In the experiment, the target is illuminated by He-Ne laser,and in terms of polarization diversity of scattering light,the polarization images of the target are obtained by the DSP system of collecting image. The Stokes images and polarization images are calculated by fusion technique. The result shows that the scattering light of background is filtered by polarization imaging ,the contrast and resolution are increased obviously. So the technique of polarization imaging can increase detective and discriminative efficiency.
