Underwater polarization imaging technology can enhance the contrast of underwater images. But due to the limitation of detector′s dynamic range, it is difficult to obtain accurate polarization information, which decreases the final enhancement results. An underwater image denoising method based on three images with arbitrary polarization analyzing angles is proposed. The enhancement results with different polarization analyzing angles are studied. The results showed that for active linear polarization illumination, it′s better to choose three angles near the orthogonal polarization direction of the incident light. For non-polarized light illumination, it′s better to choose three angles near 45° away from the polarization angle of backscattered light. The results can support the underwater active polarization imaging enhancement technology in highly turbid media, which may expand the application of underwater active polarization imaging technology.
