Abstract-For an application of polarization-difference (PD) to determine significantly polarized reflection regions in bad weather, after a theoretical introduction of polarizationdifference imaging (PDI) and dichromatic atmospheric scattering model, a series of experiments are conducted in our research. Those experiments contain three aspects: a queue scheme for image data memory that is applied to reduce noise in the process of polarization image capturing; a comparison of degree of polarization (DOP) of horizontal sky-light on rainy and clear days; an application of PD to determine significantly polarized refection regions in bad weather. Our outdoor experiments indicate that on a rainy day PD can correctively determine the significantly polarized reflection region and on a clear day PD fails to correctly determine significantly polarized reflection regions in an outdoor scene.
