Method for Water Surface Sun Glint Suppression Based on Polarized Radiation Image Fusion

Adaptive Polarizing Suppression of Sea Surface Glare Based on the Geographic Polarization Suppression Model

“…Therefore, the expression for the solar and lunar altitude angles is shown in Equation (11), and the light incidence angle is shown in Equation (12).…”

“…Within passive optical monitoring, glare resulting from the reflection of sunlight and moonlight off the sea surface can cause local saturation and distortion in optical detectors, significantly compromising the effectiveness of maritime target surveillance. Thus, accurately suppressing sea surface glare is an urgent issue that needs to be addressed for effective all-time maritime target monitoring [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

“…In addressing the suppression of sea surface glare within passive optical imaging, researchers have proposed various solutions. These include the use of the Bidirectional Reflectance Distribution Function (BRDF) [1] model to suppress sea surface glare; suppression based on the physical relationships of different spectral bands [2]; glare suppression using Noise-Driven Suppression of Glare Control (ND-SGC) [3]; and methods based on polarization filtering [4][5][6][7][8][9][10][11][12][13][14][15][16]. Compared to the BRDF model, spectral band relationships, and ND-SGC methods, polarization filtering offers significant advantages in terms of real-time capability, ease of implementation, and suppression effectiveness.…”

“…Consequently, researchers have proposed combined image processing approaches to enhance the adaptability of sea surface glare suppression methods. In 2019, Chen Wei et al [12] introduced a solar glare suppression method based on the fusion of polarimetric radiance maps. In 2021, Ye Song and colleagues [7] implemented effective suppression of sea surface glare through the temporal fusion of image sequences generated with real-time polarization information.…”
