Method for Water Surface Sun Glint Suppression Based on Polarized Radiation Image Fusion
A new sun glint suppression method is proposed based on polarized radiation image fusion. Herein, the polarization measurement of sun glint is performed using the simultaneous polarization imaging technology and the polarized radiation images of 0°, 45°, and 90° are obtained. In the polarized radiation image with the strongest glint suppression, the residual strong glint region is selected and used to generate a regional glint suppression polarization radiation image based on the calculation of Stokes parameters. The selected polarized radiation image is fused with the regional glint suppression polarized radiation image to further suppress the glint intensity. The indoor experimental results demonstrate that the proposed method can effectively suppress glint and eliminate image saturation. In addition, the obtained fusion image is more uniform than the intensity image, and the target details and contour information are clear, which significantly improves the contrast of the target relative to the flare background.
