Underwater polarized image processing based on active illumination and image fusion of circular polarized light

Compared with the traditional optical imaging and measurement technology, polarization imaging and polarization measurement technology is a new type of optical detection technology combines polarization measurement with image processing. It can not be solved by traditional optics in the field of target detection and recognition. This paper mainly studies the restoration technology of polarization image in turbid underwater environment, and uses the method of rotating polarizer to collect polarization image by active circular After calculating the Stokes vector, the polarization degree image, polarization angle image, intensity image and visible light image are fused by NSCT image fusion method. Finally, the fusion image is processed by LSCN image enhancement method to improve the quality and effect of the image.
