基于偏振特征重构的海面耀光抑制方法研究
Sea surface glint suppression method based on polarization feature reconstruction
摘要
Abstract
Sun glint is a significant factor influencing sea surface target detection.For land observation plat-forms,a sea surface glint suppression method based on the reconstruction of common and feature compon-ents of linearly polarized images is proposed using the polarization characteristics of glints.We use a focal plane polarization camera to obtain four-channel linear polarized images,calculate the scene's polarization information,and generate a glint suppression image.Based on suppressing scene glint with polarization in-formation combined with the characteristics of linear polarization images,the light intensity components of the glint suppression image are decomposed into common and characteristic components,and new weight factors are reassigned to obtain the reconstructed glint suppression image.The glint polarization imaging ex-periments show that in the three sets of typical experimental data,the proportion of saturated pixels in the re-constructed glint suppressed image is decreased by up 79.07%.Compared to the intensity image,and the spa-tial frequency and contrast are increased by up to 73.77%and 172.73%,respectively.The method proposed in this paper effectively suppresses the glint noise in the sea scene and performs well in restoring background detail information.关键词
