The measurement absolute error for polarization imaging system was obtained by analyzing polarization measurement principle. In the polarization experiment, the real polarization of the polarized light and the polarization images were calculated, and the absolute error of polarization was obtained, which is consistent with the theory analysis. The accuracy of the polarization imaging system was detected.
