  • Considering camouflage target polarization detection under the complicated background, basing the Chinese color system and CIE1976L*a*b* color space, the 256 gray levels table was established by LMS and l color space. A best polarized reference direction was found out by field experiments of the high polarization degree target-background contrast. Representing polarization information advantages- disadvantages and reflecting polarization detection capability strengths-weaknesses was further researched. Experimental results showed that, the?linearly polarization direction of perpendicular to the incident is a best reference direction, the polarization image of LMS space was reduced few information than its gray image in the bright illumination, but possessed the stronger ability of representing target polarization information; polarization image of l space was compared its gray image in low illumination, not only the contrast of targets and background was obviously improved, but also the detecting ability of shadowed target was stronger, the calculation results is consistent with the interpretation results of human eye.
